Is It Cisco ClientLink 4.0 or ClientLink 3.0?

March 23 2016 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco Wireless - Cisco Wireless AP, #Cisco Technology - IT News

Optimize Your Mixed-Client Wi-Fi Network

Optimize Your Mixed-Client Wi-Fi Network

The Cisco ClientLink Advantage

The Cisco ClientLink Advantage

Mobile devices are so popular today, which range from laptops, tablets, smartphones to others. And now all kinds of mobile device types now connect to your wireless LAN. All these mobile devices might use a mix of new and old Wi-Fi technologies – 802.11ac, 802.11n, and 802.11a connections – for access. To keep the older and slower clients from impeding the performance of newer and faster 802.11ac Wave 1 and 2 connections, there is Cisco ClientLink.

ClientLink is a beamforming capability built into Cisco Aironet wireless LAN access points. When the access point (AP) concentrates signals toward the receiving client, that client is better able to “hear” the AP’s transmission, so throughput is greater. ClientLink also enhances performance in the uplink (client-to-AP) direction, so that the AP can also better hear the client communications. The result is improved performance in both directions.

By comparison, many competing 802.11ac-capable APs offer uplink-only enhancements, from client to access point. Many 802.11ac-capable AP suppliers also base their downlink enhancements on the optional transmit beamforming (TxBF) feature in 802.11ac, which requires TxCBF support in the client device to operate. Cisco ClientLink technology is unique in offering both uplink and downlink performance improvements, and it doesn’t require any special capabilities in the client device to work.

ClientLink works with all client technologies. It makes sure each client type always operates at the best possible rate, as determined by the 802.11 access technology supported, network conditions, and the distance of the client from the Wi-Fi AP. ClientLink helps maintain maximum client rates even at cell boundaries, when clients are farthest away from the AP.

How to Get the Most from 802.11ac?

The 802.11ac standard inherently provides performance increases compared with earlier 802.11 technology versions. But because 802.11-based equipment is backward-compatible with older versions of the standard, it pays to run a mixed-client network to get the most out of your device investments. At the same time, however, your older clients can delay communications for the faster 802.11ac clients, hindering 802.11ac performance benefits.

Cisco ClientLink overcomes this issue for more reliable mobile experiences. In Aironet 802.11ac APs, ClientLink uses four transmit antennas to focus transmissions in the direction of the Wi-Fi client, surpassing the industry norm. This support improves downlink signal-to-noise ratio (for better client “hearing”) and boosts the data rate over range so you can reduce coverage holes and enhance overall system performance. Table 1 illustrates the Cisco performance advantages of using ClientLink technology.

You get beamforming enhancements across your entire client population of new and old devices: Cisco ClientLink beamforming works with all client types, and IEEE-standard transmit beamforming (TxBF) is also built into all Cisco Wi-Fi-Certified 802.11ac access points to benefit the 802.11ac clients that support it.

ClientLink also works with multiuser multiple input, multiple output (MU-MIMO), part of the 802.11ac standard that enables concurrent transmissions between an AP and multiple 802.11ac client devices that also support MU-MIMO. As a result, Cisco ClientLink can now also provide performance boosts across a mixture of 802.11ac, 802.11 n, and 802.11a clients to further benefit your entire wireless network.

The wireless difference is in the implementation details. Turn to Cisco ClientLink-enhanced APs to get best performance from all Wi-Fi clients on your network.

Cisco LAP (Lightweight Access Point), Some Questions

April 9 2015 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco Wireless - Cisco Wireless AP

Cisco LAP (Lightweight Access Point), Some Questions

Cisco LAP (Lightweight Access Point), Some Questions

A LAP is an AP that is designed to be connected to a wireless LAN (WLAN) controller (WLC). The LAP provides dual band support for IEEE 802.11a, 802.11b, and 802.11g and simultaneous air monitoring for dynamic, real-time radio frequency (RF) management. The Cisco LAP is part of the Cisco Unified Wireless Network architecture. In addition, Cisco LAPs handle time-sensitive functions, such as Layer 2 encryption, that enable Cisco WLANs to securely support voice, video, and data applications.

APs are “lightweight,” which means that they cannot act independently of a wireless LAN controller (WLC). The WLC manages the AP configurations and firmware. The APs are “zero touch” deployed, and individual configuration of APs is not necessary. The APs are also lightweight in the sense that they handle only real-time MAC functionality. The APs leave all the non-real-time MAC functionality to be processed by the WLC. This architecture is referred to as the “split MAC” architecture.

You cannot configure the LAP to operate independent of a wireless LAN controller (WLC). LAPs cannot function independent of WLCs. LAPs function in conjunction with a WLC only. The reason is that the WLC provides all the configuration parameters and firmware that the LAP needs in the registration process.

LWAPP (Lightweight AP Protocol) is an Internet Engineering Task Force (IETF) draft protocol that defines the control messaging for setup and path authentication and run-time operations. LWAPP also defines the tunneling mechanism for data traffic.

A LAP discovers a controller with the use of LWAPP discovery mechanisms. The LAP sends an LWAPP join request to the controller. The controller sends the LAP an LWAPP join response, which allows the AP to join the controller. When the LAP joins to the controller, the LAP downloads the controller software if the revisions on the LAP and controller do not match. Subsequently, the LAP is completely under the control of the controller. LWAPP secures the control communication between the LAP and the controller by means of a secure key distribution. The secure key distribution requires already provisioned X.509 digital certificates on both the LAP and the controller. Factory-installed certificates are referenced with the term "MIC", which is an acronym for Manufacturing Installed Certificate. Cisco Aironet APs that shipped before July 18, 2005, do not have a MIC. So these APs create a self-signed certificate (SSC) when they are upgraded in order to operate in lightweight mode. Controllers are programmed to accept SSCs for the authentication of specific APs.

And what is CAPWAP?

In controller software release 5.2 or later, Cisco lightweight access points use the IETF standard Control and Provisioning of Wireless Access Points protocol (CAPWAP) in order to communicate between the controller and other lightweight access points on the network. Controller software releases prior to 5.2 use the Lightweight Access Point Protocol (LWAPP) for these communications.

CAPWAP, which is based on LWAPP, is a standard, interoperable protocol that enables a controller to manage a collection of wireless access points. CAPWAP is being implemented in controller software release 5.2 for these reasons:

  • To provide an upgrade path from Cisco products that use LWAPP to next-generation Cisco products that use CAPWAP
  • To manage RFID readers and similar devices
  • To enable controllers to interoperate with third-party access points in the future

LWAPP-enabled access points can discover and join a CAPWAP controller, and conversion to a CAPWAP controller is seamless. For example, the controller discovery process and the firmware downloading process when you use CAPWAP are the same as when you use LWAPP. The one exception is for Layer 2 deployments, which are not supported by CAPWAP.

You can deploy CAPWAP controllers and LWAPP controllers on the same network. The CAPWAP-enabled software allows access points to join either a controller that runs CAPWAP or LWAPP. The only exception is the Cisco Aironet 1140 Series Access Point, which supports only CAPWAP and therefore joins only controllers that run CAPWAP. For example, an 1130 series access point can join a controller that runs either CAPWAP or LWAPP whereas an 1140 series access point can join only a controller that runs CAPWAP.

For more information, refer to the Access Point Communication Protocols section of the configuration guide.

Is it a regular AP or a LAP? The easiest way to distinguish between a regular AP and a LAP is to look at the part number of the AP.

  • LAP (Lightweight AP Protocol [LWAPP])—Part numbers always begin with AIR-LAPXXXX.
  • Autonomous AP (Cisco IOS Software)—Part numbers always begin with AIR-APXXXX.

The Cisco Aironet 1000 Series LAPs are an exception to this criteria. The part numbers of the 1000 series LAPs are:

  • AIR-AP1010-A-K9 for a 1010 LAP
  • AIR-AP1020-A-K9 for a 1020 LAP
  • AIR-AP1030-A-K9 for a 1030 LAP

Note: The part numbers can vary, which depends on the country and regulatory domain. The part numbers that this list provides are just examples.

Make sure that you order the appropriate AP for your wireless LAN (WLAN).

These Cisco Aironet AP platforms are able to run LWAPP:

  • Aironet 1500 Series
  • Cisco Aironet 1250 Series
  • Aironet 1240 AG Series
  • Aironet 1230 AG Series
  • Aironet 1200 Series
  • Aironet 1130 AG Series
  • Aironet 1000 Series
  • Aironet 1140 Series AP

Note: The 1140 Series AP is supported only with WLC that runs 5.2 release or later.

Note: You can order these Aironet APs with Cisco IOS Software to operate as autonomous APs or to operate with LWAPP. The part number determines if an AP is a Cisco IOS Software-based AP or an LWAPP-based AP. Here are examples:

  • AIR-AP1242AG-A-K9 is a Cisco IOS Software-based AP.
  • AIR-LAP1242AG-P-K9 is an LWAPP-based AP.

Note: The 1000 Series APs and the 1500 Series APs are exceptions to this criterion. All the 1000 Series APs and the 1500 Series APs support only LWAPP.

How do I install and configure an LWAPP-enabled access point? LWAPP-enabled APs are part of the Cisco Integrated Wireless Network Solution and require no manual configuration before they are mounted. The AP is configured by an LWAPP-capable Cisco Wireless LAN Controller (WLC). Refer to the Quick Start Guide LWAPP-Enabled Cisco Aironet Access Points for information on how to install and initially configure an LWAPP-enabled access point.

If I want to configure my LAP and my wireless LAN controller (WLC) together, what shall I do? LAPs use Lightweight AP Protocol (LWAPP), and when they join a WLC, the WLC sends the LAPs all the configuration parameters and firmware. Refer to the Wireless LAN Controller and Lightweight Access Point Basic Configuration Example for a basic setup.

Also you cannot connect an autonomous AP to a wireless LAN controller (WLC) and expect the AP to work. Only LAPs work when they are connected to a WLC. Autonomous APs do not understand the Lightweight AP Protocol (LWAPP) or the CAPWAP protocol that the WLC uses. In order to connect an autonomous AP to a WLC, you must first convert the autonomous AP to lightweight mode.

The number of APs supported per WLC depends on the model number:

  • 2106—A standalone WLC that supports up to 6 APs with 8 Fast Ethernet interfaces.
  • 4402—A standalone WLC that supports either 12, 25, or 50 APs.
  • 4404—A standalone WLC that supports 100 APs.
  • 5500—A standalone WLC that supports 12, 25, 50,100, or 250 access points for business-critical wireless services at locations of all sizes.
  • WLCM—A WLC module that is specifically designed for Cisco's Integrated Service Router (ISR) series. It's currently available in a 6, 8 or 12 AP version.
  • WS-C3750G—A WLC that supports either 25 or 50 APs that comes integrated with the Catalyst 3750 switch. The WLC's backplane connections appear as 2-Gig Ethernet ports that can be configured separately as dot1q trunks to provide connection into the 3750. Or the Gig ports can be link aggregated to provide a single EtherChannel connection to the 3750. Because the WLC is integrated directly, it has access to all of the advanced routing and switching features available in the 3750 stackable switch. This WLC is ideal for medium-sized offices or buildings. The `50 AP' version can scale up to 200 APs when four 3750s are stacked together as a virtual switch.
  • WiSM—A WLC module that is designed specifically for Cisco's Catalyst 6500 switch series. It supports up to 300 APs per module. Depending on the 6500 platform, multiple WISMs can be installed to offer significant scaling capabilities. The WiSM appears as a single aggregated link interface on the 6500 that can be configured as a dot1 trunk to provide connection into the 6500 backplane. This module is ideal for large buildings or campuses.

802.11ac Solution, Benefits & Migration

March 30 2015 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco Wireless - Cisco Wireless AP

wifi-80211ac

wifi-80211ac

802.11ac vs. 802.11n
802.11ac vs. 802.11n

802.11ac is important? Do you want to upgrade to 802.11ac? Why? 802.11ac addresses the speed and capacity challenges facing the next-generation unified access network

● Wi-Fi is the primary access method for all new devices.

● Cisco VNI trend data shows that by 2016 over half of all IP traffic will originate on fixed Wi-Fi.

● Chip manufacturers have accelerated their delivery timetables for 802.11ac to meet device manufacturers’ demands.

● Wi-Fi is assumed. Device manufacturers have never included Ethernet ports on smartphones or tablets, and they are no longer including Ethernet ports on laptops.

Benefits of 802.11ac

802.11ac offers longer battery life, more bandwidth, greater client density, and fast client adoption.

Longer battery life: Better airtime utilization means devices are on and off the network more efficiently, conserving precious battery life.

More bandwidth: Three to four times higher throughput than 802.11n means users have better experience for data, voice, video, virtual desktops, etc.

Greater client density: More users and more devices per user can be accommodated.

Fast client adoption: Client devices such as smartphones and tablets are adopting 802.11ac faster than 802.11n.

802.11ac radios also support 802.11a/n clients.

● Most enterprise-grade access points provide at least two radios: 2.4 GHz for 802.11b/g/n and 5 GHz for 802.11a/n.

● 802.11ac is offered only in the 5-GHz band.

802.11g/a/n vs. 802.11ac

The differences are found in frequency, speed, modulation, battery savings, and channel width.

Frequency Band: 802.11n operates in both the 2.4-GHz and 5-GHz band. Both 802.11a and 802.11ac operate in 5 GHz band only.

Speed: Some of the latest generation of 802.11n access points have a maximum datarate of 450 Mbps. Wave 1 of 802.11ac provides a maximum datarate of 1.3 Gbps, and Wave 2 will offer a maximum datarate of 6.9 Gbps.

Modulation: 802.11ac provides 256 quadrature amplitude modulation (QAM) vs. 64-QAM for 802.11n. Basically, when you have better modulation, you can transport more data. 802.11ac can operate up to three times faster than 802.11n.

Battery savings: Since 802.11ac devices are more efficient over the air, they transmit for shorter intervals, conserving battery life. 802.11ac has been shown to improve battery life by up to 2x over 802.11n.

Channel width: 802.11n allows a 20 MHz and 40-MHz channel. 802.11ac allows up to 80-MHz channels in Wave 1 and 160-MHz Channel in Wave 2.

Has the 802.11ac standard been ratified? Yes; the ratification and publication of 802.11ac by IEEE was completed December 9, 2013, and ANSI approved it on December 11, 2013. (The 802.11 timeline updates can always be found under the “RevCom & Standards Board Final or Continuous Process Approval” at http://www.ieee802.org/11/Reports/802.11_Timelines.htm.)

What is the difference between Wave 1 and Wave 2 of 802.11ac?

The biggest difference is that Wave 1 802.11ac is available now and the expectation is that 802.11ac Wave 2 will come to market in CY15.

● 802.11ac Wave 2 will require new hardware, so it will not simply be a software upgrade to current 802.11ac platforms.

The main features of 802.11ac Wave 1 include: The maximum datarate is 1.3 Gbps; Channel bonding support for 80 MHz (mandatory); Three spatial streams, single-user multiple-input and multiple-output (MIMO); Two spatial streams are mandatory for non-battery-powered access points; Only one spatial stream is mandatory for battery-powered access points and clients; Faster modulation: 256-QAM

The main features expected in 802.11ac Wave 2 include: Multi-user MIMO; Up to 8 spatial streams; 160-MHz-wide channels; Maximum datarate is 6.9Gbps

Why deploy 802.11ac Wave 1?

◦ You can expand your network and adopt 802.11ac Wave 1 today, instead of buying 802.11n or waiting for Wave 2, which won’t be available until 2015.

◦ 802.11ac Wave 1 represents fundamental improvements and enhancements to 802.11n in terms of client performance due to three to four times higher throughput than 802.11n.

◦ Device users can expect to have better experience for data, voice, video, virtual desktop, etc.

◦ Wider channel bandwidth in 802.11ac means more real estate to support higher client density in conference rooms, auditoriums, and stadiums.

◦ Client devices are adopting 802.11ac faster than 802.11n.

◦ Smartphones, tablets, and laptops are on and off the network faster with 802.11ac, thereby conserving battery life.

What benefits can I expect with 802.11ac Wave 2?

◦ MU-MIMO switch-like behavior will allow for an even higher number of concurrent Wi-Fi devices.

◦ Higher throughput is expected with the additional spatial streams and 160-MHz-wide channels.

How does Cisco support 802.11ac? Cisco also offers the Aironet 2700 and 3700 Series Access Points, both of which have integrated 802.11ac Wave 1 radios. Cisco also offers an 802.11ac module that can be added to the Cisco Aironet 3600 Series Access Points.

● The Cisco Aironet 3700 Series also support a modular architecture that allows expansion to the Wireless Security Module, the 3G Small Cell Module, and support for future technology such as 802.11ac Wave 2.

Both the Cisco Aironet 3700 and 2700 Series supports Cisco’s High Density Experience (HDX) technology.

● Cisco’s HDX High-Density Experience is a purpose-built Innovative Chipset designed specifically for the high performance environments of 802.11ac.

● The features of HDX includes:

◦ Turbo Performance which Scales to Support More Devices

◦ Running High Bandwidth Apps

◦ Optimized Roaming which Intelligently Decides the Proper

◦ Access Point as People Move

◦ Cisco’s CleanAIr with 80MHZ channel support which mitigates interference and improves channel capacity

◦ Cisco’s ClientLink 3.0 which improves legacy and 802.11ac Client performance

◦ Cross AP Noise Reduction (future) which enables dense Access Point Coexistence/implementation

Cisco AP 3700 Series: Built-for-Purpose vs. Purpose-Built

April 17 2014 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco Wireless - Cisco Wireless AP

As more and more 802.11ac devices come to the market this year, businesses need to make sure the best possible 802.11ac wireless infrastructure gets deployed to make sure those 802.11ac end points are performing at both the best possible data rates and application throughputs to maximize the move to  802.11ac.

Cisco’s Aironet 3700 with HDX Technology does just that. If you’re thinking that the 3700 is just another 802.11ac AP, think again: not all 802.11ac AP’s are created equal.

To demonstrate this, let’s take a Cisco 3700 access point...

 3700 Cisco AP

When you open a Cisco AP, you will see dedicated memory (RAM) on the radio chipset itself (one on the 2.4 GHz radio, another on the 5 Ghz radio) to ensure the RF packets get processed “onboard” each radio instead of “offboard” in order to reduce latency and any packet processing collision from memory contention on the AP. Additional packet processing can be handled  on the “offboard” memory that is part of the network processor portion of the AP platform as well. This unique, innovative ASIC-based Wi-Fi chipset by Cisco exemplifies the built-for-Purpose design, and is the hallmark of Cisco’s 3700 Series AP.

Cisco’s 3700 Series AP

Contrast this with the competitive landscape that claims to be Purpose-Built, but in reality is leveraging off-the-shelf merchant silicon-based 802.11ac WiFi chipsets. You will see on these AP’s, the memory is only available “offboard”—introducing packet transfer latency and collision—due to a shared memory between the radios and network processor. It’s that difference that explains why with a Cisco 3700 AP, you can scale 40 or more clients without aggregate throughput drop.

Built-for-Purpose also means Cisco AP 3700 comes with HDX Technology’s ClientLink 3.0, which ensures that all 802.11ac devices are operating at the maximum 11ac data rates. I speak from personal experience--my 802.11ac enabled Macbook Air shows over 800 Mbps consistently. Without Cisco’s built-for-purpose feature set, an 11ac smartphone could be toiling around at 11n rates instead—now where’s the fun with that?

At the end of the day, a built-for-purpose AP from Cisco is going to go the distance and bring you and your end-users the highest performance, optimized for the latest devices. When building out your wireless infrastructure to support all the devices and services on your network, don’t forget: not all 802.11ac AP’s are created equal, so know what you’re getting into when selecting an access point.

Cisco HDX for 802.11ac

April 11 2014 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco Wireless - Cisco Wireless AP

The introduction of 802.11ac, the latest Wi-Fi standard, brings higher data rates, better performance, and better coverage compared to earlier standards. The 802.11ac standard uses a wider channel and an improved modulation scheme that also supports more clients. It is built on the success of the 802.11n standard, improving and enhancing the best practices and making it one of the most efficient standards to date. In addition, the presence of 802.11ac can provide more efficiency for 802.11n clients.

For some organizations, the technological efficiencies of 802.11ac is creating a race to upgrade their wireless networks. The race to upgrade is also being driven by the fact that the Wave 1 portion of 802.11ac, with a maximum data rate of 1.3 Gbps, could be the last Wi-Fi solution that organizations can expect before having to upgrade their switches. This combination of factors is causing 802.11ac adoption to increase at a rapid rate, resulting in better performance and coverage for wireless networks.

With increased performance and coverage comes increased traffic. There has also been an increase in the demand for client access, including 802.11ac-enabled clients, a trend that started before 802.11ac was approved as a standard. Many businesses and organizations in industries ranging from higher education and K-12 to healthcare, manufacturing, and retail are facing the same challenges: more users are coming onto the network, users are bringing more devices, more devices offer only wireless connectivity (no Ethernet port), security demands are greater, there are more operating systems to support, and lastly, application updates are needed on each of the devices. All this leads to the larger problem of high density.

However, not all 802.11ac access points are alike and some are not designed to handle higher density. To get the most out of an 802.11ac deployment, an organization must take into account certain fundamental considerations.

Enter Cisco High Density Experience (HDX) technology. Available on the Cisco Aironet 3700 and 2700 Series Access Points, Cisco HDX technology is a suite of solutions combining a feature set designed specifically to alleviate the introduction of more clients, more access points, bandwidth-hungry applications, and high-density network strain while providing an unparalleled user experience.

Cisco-2700-Series-AP-and-3700-Series-AP.jpg

HDX helps optimize performance, mitigation, scalability, and roaming for high-density wireless networks. Additionally, HDX is a hardware-based solution on a Wi-Fi chipset designed by and for Cisco. It is not simply a set of software features based on a merchant silicon Wi-Fi chipset. It is a purpose-built application-specific integrated circuit (ASIC) that allows networks to get the most out of 802.11ac while also improving the overall performance of their wireless network.

HDX-Cisco.jpg

 

HDX features include the following:

Cisco CleanAir for 80-MHz Channels

With Cisco CleanAir for 80-MHz channels, Cisco has fundamentally retooled the award-winning CleanAir technology to support the entire 80-MHz channel supported by 802.11ac while providing the same level of granularity and accuracy of RF interference detection as before.

The benefit of an 80-MHz channel is the potential to double usable throughput in comparison to the 40-MHz-wide channel used by 802.11n. However, a wider RF channel is also more susceptible to interference. In other words, 802.11ac devices “hear more” than 802.11n devices, primarily due to the wider channel support.

Not all 802.11ac access points perform well in the presence of interference. With the increasing number of clients per access point, number of access points in a given wireless network, and number of wireless networks themselves, wireless network operators and administrators are challenged to maintain performance when interference exists. In brief, for high-performance and high-density environments, spectrum intelligence continues to matter. When interference can be detected and identified, it can be mitigated.

For these reasons, Cisco CleanAir technology is a key feature in Cisco’s HDX solution. Because of the increased channel bandwidth for 802.11ac networks, and the increasing density of wireless networks, CleanAir is essential to help assure that no significant degradation or suboptimal performance results from the migration to 802.11ac and the concurrent growth in high-density deployments.

 

ClientLink 3.0

Cisco ClientLink 3.0, as part of HDX, can perform Cisco’s patented beamforming technology with 802.11ac clients as well as 802.11a/g/n clients. In fact, ClientLink 3.0 complements standards-based Explicit Compressed Beamforming Feedback (ECBF) in which more and more 802.11ac clients will actively participate. ClientLink 3.0 improves the downstream performance and throughput from the access point to the client as well as improving the upstream performance and throughput from the client to the access point. This improves the quality of the connectivity between client and access point, resulting in a more stable network connection.

ClientLink 3.0 will also benefit the wireless network transition from 802.11n to 802.11ac. Every new wireless standard adoption comes with the challenge of a mixed-device environment. We saw it when running 802.11n with the mix of 802.11a/g devices, and we are now seeing it with 802.11ac and a more convoluted mix of 802.11a/n devices. There is a high chance that your office or enterprise will have a blended presence of legacy 802.11a, 802.11n, and 802.11ac client devices coexisting together. ClientLink 3.0 helps solve issues involved in mixed-client networks by enabling higher data rates for both legacy and newer clients, even when they are connected to the same access point. With ClientLink 3.0, networks will be able to enjoy the benefits of 802.11ac with a more efficient and higher-performing Wi-Fi experience.

 

Turbo Performance

Turbo Performance with HDX technology allows the supporting access points to scale to 60 clients or more, with each client running media-rich video or interactive traffic, without any performance degradation. This is especially important in networks with high client density, in which some competitors fall short at 10 or 20 clients.

Turbo Performance is important with 802.11ac because of the higher data rates, which equate to more packets per second (PPS) flowing through the access point. For example, with 802.11n, an access point might have had to push 30,000 1500-byte packets per second (PPS) through the access point’s data plane. Today, with 802.11ac, that could be 75,000 PPS or more. More PPS means more load on the access point’s CPU, so to really keep up with the demands of 802.11ac, a redesigned access point is needed.

With Turbo Performance, Cisco has fundamentally retooled its access point design specifically for 802.11ac. The result is much less CPU-intensive processing and a much more efficient packet scheduler delivering 802.11ac speeds at a much larger scale than the competition. 802.11ac allows for speeds never before seen on a Wi-Fi access point. Cisco understood the demands caused by these increased speeds and, with HDX Turbo Performance, has fundamentally reworked the data plane in order to enable unrivaled 802.11ac performance and scalability.

 

Optimized Roaming

Optimized Roaming allows clients to roam more intelligently and cleanly between access points as well as between unlicensed and licensed cells. It addresses a fundamental problem called stickiness in which the client stubbornly stays connected to an access point that it connected to earlier, even though the client has physically moved closer to another access point.

With Optimized Roaming, a Cisco access point continuously evaluates the quality of the Wi-Fi connection for each associated device and can actively disconnect a device upon detecting that the device is moving into a region of poor coverage. This disconnection forces the client to enter its scanning mode much earlier than it ordinarily would, terminating a connection that is becoming essentially unusable and allowing the client to connect to an access point with better performance.

Optimized Roaming not only benefits the end user but also improves the overall performance of the access points and therefore the experience of other users. A client that is gradually degrading in performance (and possibly degrading faster than it can dynamically rate-adapt to or compensate for) may cause a large number of retransmissions, which consume airtime. If enough clients are being sticky, the performance of the access point can be degraded. Therefore, sticky clients that maintain poor connections can easily affect well-behaved clients.

Optimized Roaming helps prevent a negative experience for Wi-Fi users by monitoring the connection quality of all devices and proactively prompting poorly performing client devices to seek a better connection much sooner.

 

RF Noise Reduction

RF Noise Reduction allows the access point to be more efficient in its use of the RF spectrum and possibly to recycle channels. This feature allows neighboring or adjacent access points to use the same channel to increase overlay density and mitigate configuration errors. With RF Noise Reduction, it is possible to deploy more access points in a given area to meet strenuous service-level agreements (SLAs). This is important for networks with extremely high client density, because it allows the deployment of additional access points to handle the higher client demand. RF Noise Reduction will be available in a future release.

If you are an enterprise IT manager and you are considering deploying 802.11ac for your wireless network, you must ask yourself if all 802.11ac access points are alike. 802.11ac has some great benefits, such as wirelike speed and the ability to handle a high concentration of clients. However, there is more to consider when deploying 802.11ac. For instance, how do you handle RF interference now that 802.11ac supports 80-MHz channels? Will legacy devices such as 802.11a/g/n allow you to achieve the best performance that 802.11ac is capable of? How can you ensure that your users get the best wireless performance when they roam across a building? And lastly, as more clients join the network, is your performance going to suffer? These are all valid concerns that Cisco addresses with its HDX solution. HDX is a necessary component of a wireless network, complementing 802.11ac while helping ensure that you get the best performance out of your wireless network.

What did Aironet 2600 Series users say?

“The Aironet 2602E is designed for commercial use. This particular model requires separate controller to work. So be careful when you order it. It does not come with power supply; it's understandable, as it was designed for work with POE switch.”
