Cisco ASR 1000 Series Use Cases

March 21 2017 , Written by Cisco & Cisco Router, Network Switch Published on #Networking, #Cisco Routers, #Technology, #Cisco Technology - IT News

When your enterprises or organization are going to choose the Cisco ASR 1000 Series, you should know these Cisco ASR 1000 Series Enterprise and Service Provider Applications.

Cisco ASR 1000 Series routers sit at the edge of your enterprise data center or large office connecting to the WAN, as well as in service provider points of presence (POPs). The Cisco ASR 1000 Series will benefit the following types of customers:

  • Enterprises experiencing explosive network traffic as mobility, cloud networking, and video and collaboration usage increase: Cisco ASRs consolidate these various traffic streams and apply traffic management and redundancy properties to them to maintain consistent performance among enterprise sites and cloud locations.
  • Network service providers needing to deliver high-performance services, such as DCI and branch-office server aggregation, to business customers: Service providers can also use the multiservice routers to deploy hosted and managed services to business and multimedia services to residential customers.
  • Existing Cisco 7200 Series Router (end-of-sale) customers looking for simple migration to a new multiservice platform that delivers greater performance with the same design.

Tables2 and Table3 describe enterprise and service provider application examples, respectively.

Table2. Cisco ASR 1000 Series Enterprise Applications

Deployment Scenario

Description

System Characteristics

Embedded high-speed firewall:

With the Zone-Based Policy Firewall, the Cisco ASR 1000 Series acts as an implicit and complete barrier between any interfaces not members of the same zone. An explicit zone-pair policy must be specified (using Cisco Policy Language; that is, MQC) in each direction between each zone pair. The policy establishes within the router the kind of stateful inspection (Layer 4, Layer 7, or application) and session parameters to apply to each zone pairing.

Example: An explicit policy allowing HTTP and Domain Name System (DNS) to traverse the Internet-demilitarized zone (DMZ) zone boundary would be required.

● The firewall is embedded in the Cisco Flow Processor; no additional service blades or modules are required.

● Multiple gigabits of bandwidth are routed while at the same time the router performs Zone‑Based Policy Firewall and other baseline features such as QoS, IPv4, IPv6, NetFlow, and others.

● The Cisco ASR 1000 Series provides logging of all firewall session states off to network management applications capable of accepting relatively huge amounts of flow data. Third-party applications can handle the session data.

● Provides firewall performance of 2.5 to 200 Gbps, depending on the ESP used

● Offers high-speed logging of 40,000 sessions per second with NetFlow Version 9

Managed CPE: This implementation of branch-office architecture offers powerful investment protection with services and scale.

● Managed customer premises equipment (CPE) helps branch offices route correctly over various types of Ethernet to comply with service-level agreements (SLAs).

● This application encrypts multiple gigabits of bandwidth without any additional service blades or modules.

● Managed CPE optimizes the WAN to route around brownouts in the service provider network to further guarantee mission-critical applications.

● This application offers small form factors (1 rack unit [1RU] for the Cisco ASR 1001-X and ASR 1001-HX and 2RUs for the Cisco ASR 1002-HX and ASR 1002-X Routers), including software modularity and ISSU.

Note: ISSU is not supported on Cisco ASR 1001-X, ASR 1001-HX, ASR 1002-HX, ASR 1002-X, or ASR 1004. Managed CPE offers accessibility even when the Cisco IOS Software is down.

● Offers first-in-industry software redundancy support, without any additional hardware module, on Cisco ASR 1001-X, ASR 1001-HX, ASR 1002-HX, ASR 1002-X, and ASR 1004; hardware redundancy and ISSU are supported on the Cisco ASR 1006 and ASR 1013.

LiFi vs. WiFi-Basic Difference between LiFi and WiFi

February 8 2017 , Written by Cisco & Cisco Router, Network Switch Published on #Networking, #Cisco Technology - IT News

In the last article, we told what Li-Fi is and what LiFi system basics are. It seems a cool technology in network communication? Compared to today’s popular Wi-Fi, can you tell some difference between them? In this article we list some main differences between LiFi and WiFi. Which one is better? Let’s check.

We know that Li-Fi is the short form of Light Fidelity and Wi-Fi is the short form of Wireless Fidelity. LiFi uses light for data transmission while WiFi uses electro-magnetic waves at radio frequencies for data transmission. Due to less interference incurred by light compare to radio frequency waves, it is used in more dense environments.

LiFi covers distance of about 10 meters while WiFi covers about 30 meters. Both provides almost same data transfer rate. Let us understand Li-Fi internet and Wi-Fi internet network architectures.

Figure-1: Li-Fi internet

The figure-1 depicts Li-Fi internet network architecture. As shown in the figure there are two major components in Li-Fi internet viz. LED Lamp and Li-Fi Dongle.

• As shown lamp driver is connected with internet on one end and with LED lamps on the other end. Streaming content from internet are pushed to the LED lamps through Lamp driver software.

• LED lamps are placed at different locations as per requirement in the office or home premises for multiple users.

• Li-Fi dongle is used in order to use Li-Fi internet services by various users. As shown Person#1 is browsing internet in Laptop, Person#2 in tablet and Person#3 in smartphone.

• As shown LiFi dongle is composed of photodetector, amplification & processing and applications for different types of data.

• All the LED lamps can be swithed on and off using a power button switch provided.

• Li-Fi internet provides very fast data rate at 1 Gbps speed.

Figure-2: Wi-Fi internet

 

• The figure-2 depicts Wi-Fi internet network architecture.

• As shown in the figure there are two major components in WiFi internet viz. WiFi router and WiFi dongle or WiFi Stations.

• WiFi router is connected with ADSL modem or Cable modem. This modem is connected with network of internet service provider.

• WiFi router works on multiple bands (e.g. 2.4 or 4.9 or 5 GHz) as per requirement. It converts internet data packets into wifi compliant signals at above bands. WiFi works on IEEE 802.11 standards.

• These EM waves are received by WiFi dongles or Stations connected with IP compliant devices. Hence WiFi internet is used by various clients as shown in the figure-2.

In the following table we will list the basic difference between LiFi and WiFi technologies.

Feature Comparison: LiFi vs. WiFi

Lifi is not the replacement of wifi technology. It can be considered as incredible companion of the wifi technology. It operates between 380 nm to 780 nm optical range. LiFi is used to exchange data incredibly rapidly and securely at much lower power level compare to WiFi.

Introduction to LiFi Internet

February 6 2017 , Written by Cisco & Cisco Router, Network Switch Published on #Networking, #Cisco Technology - IT News

Do you hear of Li-Fi? Maybe you are familiar with Wi-Fi in today’s network world, but you may not know much about the new Li-Fi.

What’s the Li-Fi?

LiFi is the short form of "Light Fidelity". It works on the principle of Visible Light Communication (i.e. VLC). The network is also referred as VPAN or VLC Personal Area Network. The VLC transmits data by intensity modulation. It uses LEDs and Laser diodes (or photo detectors) at transmit and receive ends respectively. It works in 380 nm to 780 nm optical band which is visible light and hence the name VLC.

The VLC standard or VPAN standard defines three classes of devices viz. infrastructure, mobile and vehicle. These devices operate in one of the three topologies mentioned below. The different device has different coverage range, data rate and other requirements.

In this article we will share the LiFi tutorial that covers LiFi system basics. This LiFi tutorial covers LiFi network architecture, LiFi protocol stack, LiFi PHY, LiFi MAC, LiFi bands, LiFi modulation types (OOK, VPPM, CSK).

LiFi Network Topologies

It works in three modes as mentioned above in the figure above. In star topology, communication is established between central controller (i.e. coordinator) and devices. In peer to peer topology, one of the devices should become coordinator at the time of establishing association.

Each device or coordinator has unique 64 bit address. Device can use 16 bit address also upon request at the time of establishing association with coordinator.

LiFi Protocol Stack

 

The figure above depicts protocol stack used in a typical VPAN device. As shown protocol stack consists of PHY, MAC and upper layers.

Physical layer houses light transceiver. PHY switch housed in PHY layer interfaces with optical SAP which connects it to the optical medium. The optical medium composed of one or multiple optical sources or optical detectors (e.g. laser diodes or photodiodes).

MAC layer provides channel access for all types of data and control message transmissions.

Upper layer consists of network layer and application layer. Network layer takes care of providing network configuration, network manipulation, message routing etc. Application layer takes care of providing intended functionality as needed by the VPAN or LiFi device.

DME (Device Management Entity) is also supported by LiFi or VPAN network architecture. It makes interfacing between dimmer and PHY/MAC a reality.

LiFi PHY

There are three types of physical layer configurations supported in VLC or LiFi System Viz. PHY-I, PHY-II, PHY-III. Different rates can be achieved in different configurations. They can be used indoor or outdoor.
Refer LiFI PHYSICAL LAYER.

LiFi MAC

MAC layer takes care of resource management i.e. allocation of channels, IDs as well as entire network management. Refer LiFi MAC LAYER.

LiFi Modulation Types-OOK, VPPM, CSK

There are different modulation schemes used in different physical layer modes. OOK stands for On Off Keying, VPPM stands for Variable Pulse Position Modulation and CSK stands for Color Shift Keying.

Applications of LiFi or VLC system

 

There are many applications of LiFi or VLC system as lighting and data communications. Typical among them are lighting, signboards, street lights, vehicles and traffic signals or lights. The figure mentions emerging application of LiFi for internet data communication. It has also become popular due to wide adoption of IoT based technologies.

Benefits of LiFi System

Following are the benefits of LiFi system:

• It transfers data very rapidly.

• It transfers data securely as it can be used in Line of Sight mode of optical signal. It does not pierce through the walls and hence it cannot be easily intruded by hackers.

• It uses much low power for transmission compare to other systems such as WiFi.

Note: Information provided on this page is derived from IEEE 802.15.7-2011 draft version. The standard describes PHY layer and MAC layer of Short Range Wireless Optical Communication using Visible Light. The standard is also referred as VPAN or VLC-PAN. Here 'V' or 'VLC' stands for Visible Light Communication. Pls. refer latest standard specifications published time to time by IEEE for any updates.

What do the Audiences say about the new Li-Fi?

Shabaz202khan Jun 8, 2016

Lifi is nowhere near to become Wifi's alternative. There a huge difference between their working hence, application areas. Wifi is a lot more flexible to use than Lifi. It can be used parallel with wifi but there's no way it will replace wifi completely.

Here are some facts to support my upper statement. No matter how fast or secure Lifi is, there are still few drawbacks and limitations that may stop it from becoming a true alternative to existing wifi. Let me write a few-

1. Range and Line of Sight: This one is pretty common. Lifi requires a direct line of sight to work efficiently; your signal can be interrupted by almost any obstacle lying between you and your lifi source. Light can't pass through walls, hence, your signal is restricted to the room only; where the light can't reach. If you move out of sight of LED, you lose connectivity.

2. Cost: As I already told above, you need to be strictly in direct sight of LED to use it efficiently, meaning you may need at least one device for each of your sitting places in your house. And you also need an individual lifi receiver for each of your device that you want to use the internet on. Plus the fact that you may need to rewire your house too as the lifi LED will need ethernet wire to produce work. The cost is going to be way more than normal Wifi.

Juan Gonzalez

Comcast already use Wi-Fi with speeds over 2GBps, faster than the one you are talking. But, but, I belive that I read that Li-Fi is able to get over 200 GBps, so I think you need to update your information about this matter.

Read this http://www.telegraph.co.uk/technology/apple/iphone/12107410/Future-iPhones-could-feature-Li-Fi-a-technology-100-times-faster-than-Wi-Fi.html

RobStow

If 1Gbps is 100 times faster than your WiFi, that implies a slow10 Mbps WiFi.

I just transferred, via WiFi, a 3.909 GB rar file from my desktop to my laptop. That took 961 seconds ... which means I got about 32.5 Mbps *REAL* transfer rate. The modem/router from my ISP is about 2 years old and my laptop and desktop are both about 3 years old: might the file transfer have gone faster with newer/better hardware?

Deploying Cisco ASA FirePOWER Services in the Data Center

January 3 2017 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco Switches - Cisco Firewall, #Networking, #Cisco & Cisco Network, #Cisco Technology - IT News

The Data Center is a one of popular words in network communication. And it can be definited as a very complex world.

The Data Center not only provides a rich set of services and architectures but also hosts the crown jewels of an organization. It is extremely important to maintain visibility of everything that is happening in the data center.

The concept of “north-to-south” and “east-to-west” is often used in describing the types of communication (or flow) within and to the outside of the data center:

  • North-to-south describes communication between end users and external entities.
  • East-to-west describes communication between entities in the data center.

The following Figure illustrates the concepts of north-to-south and east-to-west communication.

 

The data center has many different high-throughput and low-latency requirements, in addition to increased high-availability requirements. In addition, automated provisioning and control with orchestration, monitoring, and management tools are crucial.

The data center architecture consists of three primary modular layers with hierarchical interdependencies:

  • Data center foundation: This is the primary building block of the data center, on which all other services rely. Regardless of the size of the data center, the foundation must be resilient, scalable, and flexible to support data center services that add value, performance, and reliability. The data center foundation provides the computing necessary to support the applications that process information and the seamless transport between servers, storage, and the end users who access the applications.
  • Data center services: These services include infrastructure components to enhance the security of the applications and access to critical data. They also include virtual switching services to extend the network control in a seamless manner from the foundation network into the hypervisor systems on servers to increase control and reduce operational costs (as well as other application resilience services).
  • User services: These services include email, order processing, and file sharing or any other applications in the data center that rely on the data center foundation and services, like database applications, modeling, and transaction processing.

The Figure below illustrates some of the components of the data center services architecture.

 

Examples of the data center service insertion components include the following:

  • Firewalls (In the example illustrated in the Figure above, Cisco ASAs with FirePOWER modules are deployed.)
  • Intrusion prevention systems (IPS)
  • Application delivery features
  • Server load balancing
  • Network analysis tools (such as NetFlow)
  • Virtualized services deployed in a distributed manner along with virtual machines
  • Traffic direction with vPath and Nexus 1000v
  • Application Centric Infrastructure (ACI) automated framework components for service insertion

In the case of virtualized environments, the Cisco ASAv (virtual machine) can be deployed to protect VM-to-VM communication. The Cisco ASA FirePOWER module in these environments is not supported, as the Cisco ASAv is just a virtual machine. Cisco FirePOWER virtual machines running network AMP can be deployed in those scenarios.

NOTE: The Cisco ASAv supports both traditional tiered data center deployments and the fabric-based deployments of Cisco ACI environments. The Cisco ASAv can also be deployed in cloud environments like Amazon Web Services (AWS).

The Cisco ASA with FirePOWER modules can be deployed in geographically dispersed cluster environments.

The following Figure shows an example in which four Cisco ASAs with FirePOWER modules are deployed in two separate sites (site A and site B).

 

In the example illustrated in the Figure above, the cluster of four Cisco ASAs is fully extended between the two data centers, using the cluster control links (CCL) operating at Layer 2 with a latency of less than 10 milliseconds. A single spanned EtherChannel for transient data is used on the cluster side. The local data links are also configured with EtherChannels at the switch pairs on each site.

TIP: The data VLANs between the switches are not extended to prevent network loops.

What You can Do with Cisco AVB?

December 1 2016 , Written by Cisco & Cisco Router, Network Switch Published on #Networking, #Cisco Switches - Cisco Firewall, #Cisco Technology - IT News

Cisco Simplifies Digitization of Audio Video Networks with IEEE Audio Video Bridging

Do you want more audio-video flexibility without spending too much money? If yes, you can try Cisco’s new AVB. What is Audio Video Bridging?

Audio video (AV) equipment deployments have traditionally been single-purpose, analog, point-to-point connections with one-way links. As AV deployments migrate to digital, they have continued to retain this inflexible point to-point architecture. This dedicated connection model also results in a mass of cabling that is difficult and costly to manage. In contrast, an open-standards based Ethernet infrastructure enables flexibility and transparent interoperability of multi-vendor AV equipment and integration of new services.

How did AVB come about, and what does it all mean? AVB is a set of technical standards created by the IEEE Audio Video Bridging Task Group. The IEEE AVB Task Group is a part of the IEEE 802.1 standards committee. IEEE 802.1 defined a set of standards that provided the means for highly reliable delivery of low-latency, time-synchronized AV streaming services through Layer 2 Ethernet networks.

The IEEE 802.1 Audio Video Bridging (AVB) standard enables this digital transition and accelerates the adoption of Ethernet-based AV deployments that are interoperable. The IEEE 802.1 AVB defines a mechanism whereby the endpoints and the network function as a whole. This allows high-quality AV streaming of professional AV over an Ethernet infrastructure. Instead of one-to-one, the network transport enables many-to-many seamless plug-n-play connections for multiple AV endpoints including talkers and listeners. This helps corporations lower total cost of ownership through fewer cables (CapEx) and no license fees for any proprietary technologies (OpEx). It also provides higher quality, time-synchronized AV with more scalability. This scalability includes a more efficient deployment, installation and management enabling new capabilities.

If you want to see how each standard interacts with AVB and for more about the subject, read the “Cisco Audio Video Bridging Design and Deployment for an Enterprise Network” white paper.

http://www.cisco.com/c/en/us/products/collateral/switches/nexus-7000-series-switches/white-paper-c11-736890.html

Cisco simplifies digitization of AV networks with AVB support on industry leading switches.

KVM (Kernel Virtual Machines) App Hosting on a Cisco Router-Benefits

KVM (Kernel Virtual Machines) App Hosting on a Cisco Router-Benefits

Use Spare Router Cycles to Host Linux VMs

In this summer, Cisco introduced a capability that we quietly rolled out in a software release last November (IOS XE 3.17). You can now host your own custom or third party KVM lightweight applications directly on your ISR 4000 or ASR 1000.

Kernel-based Virtual Machines, the KVM, are the standard virtualization technology in the embedded Linux world. If you’re writing applications to be hosted across a network, odds are you’re already using it. The ability to virtualize across the network is a key aspect of Cisco DNA so this capability dovetails very nicely with the larger solution for enterprise environments.

Get the Most from Your Branch Router

Many lightweight applications and network functions needed in a modern network or branch office are available as virtual machines (VM). If you need to host some of these functions in the network, use your Cisco router to do it instead of deploying a dedicated appliance at your branch site.

You’ll reduce complexity and cost by making use of spare compute horsepower that’s already in your router. Very efficient.

Run the Apps You Need...

Use the Cisco 4000 Series Integrated Services Router (ISR) and ASR 1000 Series Aggregation Services Router to host not only Cisco apps, but also third-party and homegrown Linux-based apps. These routers’ Cisco IOS XE operating system supports the Kernel-based Virtual Machine (KVM), a virtualization infrastructure for the Linux kernel that turns it into a hypervisor.

Both routers use a customized high-performance data plane for forwarding and manipulating packets. The control plane is entirely Linux running on an x86 Intel CPU. We designed the routers with extra CPU capacity for hosting VMs.

You can also turn to the Cisco 4000 Series ISR and ASR 1000 Series to host other network functions that can be deployed as VMs, including:

• Windows domain controller

• Print servers

• Network analytics

• Network functions such as WAN optimization (Cisco WAAS), intrusion detection and prevention (Snort IPS), and visibility and security intelligence (Cisco Stealthwatch Learning Network License)

Hosting those VMs directly on your existing physical router makes a whole lot of sense.

...With the Performance You Expect

VMs are not hosted in the data plane of the router, so there is no performance impact on packet forwarding or feature processing. Critical control plane functions run at a higher priority than hosted VMs.

This is industry-standard Linux virtualization at its finest.

Cisco Aironet 3800 Series APs, Flexible Radio Assignment Here

August 22 2016 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco Wireless - Cisco Wireless AP, #Cisco Technology - IT News

Putting the ‘Flexible’ in Flexible Radio Assignment

Putting the ‘Flexible’ in Flexible Radio Assignment

Flexible Radio Assignment-Cisco

Flexible Radio Assignment-Cisco

You can relax when you have Cisco Aironet 3800 Series Access Points deployed and running.

Why? Cisco Aironet 3800 Series Access Points and Cisco Aironet 2800 Series Access Points support 802.11ac Wave 2, increasing bandwidth for more devices. Cisco goes beyond the industry standard to provide advanced innovation that self-optimizes your network in unpredicted times of high density, with a feature called Cisco Flexible Radio Assignment.

In addition to the device deluge, there are times when a lot of people moving in and out of your network can complicate a high-density network environment. A manual approach to recalibrating your wireless network every time there is an unexpected usage change isn’t practical. Flexible Radio Assignment automatically adapts to these temporary high-density environment changes.

Flexible Radio Assignment is a Cisco innovation designed to provide a better mobile user experience for high-density networks by automatically detecting when a large number of devices are connected to a network. Once the detection is made, Flexible Radio Assignment changes its dual radios in the access point from 2.4 GHz/5 GHz to 5 GHz/5 GHz to serve more clients. The access point performs this function while still monitoring the network for security threats and RF interference that may affect performance.

Flexible Radio Assignment has three different modes of operation:

• Default operating mode, which serves clients on both 2.4 GHz and 5 GHz

• Dual 5-GHz mode, which serves clients on both 5-GHz radios

• Wireless security monitoring, which scans both 2.4 GHz and 5 GHz for security threats while also serving 5-GHz clients

How do these features work in an everyday setting?

The best way to describe this feature is by returning to the original scenario of a large number of office workers expecting to hear a speech from the boss.

As the first group of workers trickles into the conference room, the Cisco Aironet 3800 Series Access Points automatically determine that there is ample 2.4-GHz and 5-GHz wireless coverage. During the minutes before the meeting, these access points use the wireless security-monitoring mode in the 2.4-GHz radio to continually scan both bands for RF interference or security threats. Cisco CleanAir Technology eliminates any detected interference while rogue detection and containment and wireless intrusion prevention systems (wIPS) rectify security threats.

As the meeting looms closer and the high-density scenario is realized, Flexible Radio Assignment adapts in real time, and the Cisco access point radios provide the precise amount of 2.4-GHz and 5-GHz coverage. Some access points will convert both radios to the 5-GHz band to serve the additional clients and provide better coverage and performance during the high-density event.

This availability of the larger band is extremely helpful, as a majority of the audience is following the video feed of the conference over their wireless devices too.

Following the meeting, the access points return to default operating mode, offering 2.4-GHz/5-GHz coverage while other access points transition to wireless security monitoring mode.

The most amazing thing about this scenario is that, as the network administrator, you didn’t have to do anything to facilitate the extra bandwidth. The Cisco Aironet access point is intelligent enough to do the entire thing itself. This allows you to concentrate on more pressing issues.

Flexible Radio Assignment isn’t strictly for workplace environments.

It can be used in nearly any instance where a large group of people gather. Whether it’s in an educational setting, a hotel lobby, or a hospital, Flexible Radio Assignment is a boon to any wireless network.

From bring your own device (BYOD) to Internet-of-Things (IoT) devices, the proliferation of wireless items brings a new host of challenges as bandwidth-intense applications grow. Flexible Radio Assignment rises to these challenges and augments your wireless network to do more without making your job difficult.

Now if only the Flexible Radio Assignment could give Bob from accounting some new jokes.

802.11ac Wave 2’s Impact is World Wide, WHY?

July 13 2016 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco Wireless - Cisco Wireless AP, #Cisco & Cisco Network, #Cisco Technology - IT News

802.11ac Wave 2’s Impact is World Wide

802.11ac Wave 2’s Impact is World Wide

802.11ac Wave 2 APs

802.11ac Wave 2 APs

Everyone says I love 802.11ac Wave 2. The Impact of 802.11ac Wave 2 is World Wide, Why? We also talked about the 802.11ac Wave 2 and 802.11ac Wave 2 Access Points a lot.

Yes, make no mistake the affect of the 802.11ac Wave 2 standard is going to be global and won’t just affect specific business areas.

One key part of Wave 2 802.11ac technology that helps keep your organization ahead of the capacity crunch is multi-user MIMO (MU-MIMO).

(MU-MIMO allows an access point to transmit to multiple clients at the same time, instead of sending data to a single client at a time. These parallel transmissions improve RF efficiency when client devices also support 802.11ac Wave 2.)

With Muti-User MIMO (MU-MIMO), 802.11ac Wave 2 clients are on and off the network so fast allowing for more legacy clients to be served. Plus 802.11ac Wave 2-enabled smart phones, laptops and tablets, will jump on the 5Ghz band leaving the 2.4GHz bands for older devices.

With the higher speeds of 802.11ac Wave 2, it takes a lot less time to transmit data than it did with previous Wi-Fi standards. This preserves battery life on Wave 2 clients. That means in the long run, updating your wireless network to 802.11ac Wave 2 standards will provide a better user experience for your users.

Now, let’s look at why 802.11ac Wave 2’s Impact is World Wide.

Schools need to support 802.11ac Wave 2 because more and more students are bringing devices to class. And it’s not to sneak a peek at the latest Taylor Swift video; educators are using tablets and other mobile devices as part of the education process. While additional devices and apps that will consume bandwidth are a big reason for the upgrade, it’s not the only thing. Schools need an 802.11ac Wave 2 network that can:

• Support up-to-the minute notification on mobile devices.
• Detect externally launched attacks and insider threats.
• Automatically adapts to environment changes for optimal performa
nce.

Whether you’re a small coffee shop or a large department store, it’s not just your workers that need exemplary Wi-Fi, customers demand this service too. Cisco Aironet Access Points are great tools to gather data in order to understand customer traffic patterns and behaviors, prioritizing your business-driving apps and better protecting the privacy of your business. Your customers need to be able to jump on a network too and:

• Connect to a custom guest access network (which can be used as another advertising venue).
• Be able to find the things that they want, quicker.
• Adapt to flash crowds during sales eve
nts.

In the old days, putting out an array of stale donuts in the morning and offering travelers a bed for the night was the peak of hospitality luxury. Those days are long gone as guests are now a bit savvier than they once were and expect a multitude of high-end services. One of these services is a robust wireless network. If you’re in the hospitality game, you need an 802.11ac Wave 2 compliant network because:

• It delivers mobile check-in, key lock and room control
• It quickly deploys wireless access for conventions and social gatherings
• It adapts to crowd surges during high volume of registra
tion

Where Does Cisco Fit In?

That third bullet brings me to one of the most amazing things about the Cisco Aironet Access Points, and that are the innovations that only Cisco delivers:

Flexible Radio Assignment automatically adjusts radio bands to better serve the environment. A Cisco Aironet Access Point deployed in a hotel lobby can handle a crowd of people armed with mobile devices frantically looking to get settled in their rooms. Flexible Radio Assignment automatically triggers the access point to shift from the dual radios operation at 2.4GHz and 5GHz to both radios offering 5GHz.
• Cisco CleanAir remediates device impacting interference
• Optimized Roaming intelligently connects the proper access point as people move
Multi-Gigabit Uplinks provides faster wired network offload on existing Ethernet

Your Cisco 802.11ac Wave 2 access points aren’t static. They offer investment protection via the ability to expand along with your organization with three ports located on the Cisco Access Point. A smart antenna port allows you to add either another antenna be it of the Stadium Panel, Directional or Location variety. A built-in module port is perfect for connecting hardware such as a video surveillance device. While a USB port allows you to add a Bluetooth capabiities.

Preparing for 802.11ac Wave 2 is not a one-sized-fits-all solution. Cisco has a wide access point portfolio that offers different solutions to fit different situations. The Cisco Aironet 1830 and 1850 Series Access Points are perfect fits for small to medium-sized businesses. These devices offer the functions and features of an enterprise-level access point and they are the lowest cost 802.11ac Wave 2 AP on the market today.

For mission-critical organizations, look no further that Cisco Aironet 2800 Series Access Point. More robust than the Cisco Aironet 1830 and 1850 Access Points, the 2800 Series is built for large sized organizations. Rounding out the portfolio is the Best-in-Class solution: the Cisco Aironet 3800 Access Point. This product is targeted specifically for larger areas such as stadiums and arenas.
