You may have heard of Wi-Fi 6 since 2017. Wi-Fi 6 (the newest generation of Wi-Fi) is the next-generation wireless standard that’s faster than 802.11ac, is also known as 802.11ax.
Standards-based Wi-Fi 6 will be available in 2019. Wi-Fi 6 will dramatically improve the wireless experience, and it will enable new use cases for wireless that weren’t possible before.
What are the benefits of Wi-Fi 6? Read the following 6 points.
1. More reliable Wi-Fi
With added reliability, 802.11ax will no longer be the second choice to cellular, with a consistent, dependable network connection that will provide a seamless experience for clients, IoT, and all apps, especially voice and video.
2. More capacity for your network
Addressing the growth of wireless clients, especially IoT, 802.11ax can transmit more data across the airways than previous Wi-Fi standards, as well as serve hundreds and hundreds of active clients per access point.
3. Faster Wi-Fi with more bandwidth
With every new Wi-Fi standard comes an improvement in speed. 802.11ax is no different. It is up to 3 times faster than 802.11ac, improving the user experience and the performance of bandwidth-hungry apps such as voice, video, and collaboration.
4. Improving the 2.4-GHz band is ideal for IoT
The last improvement to 2.4 GHz was 10 years ago with 802.11n. With new improvements to 2.4GHz, 802.11ax is ideal for IoT devices that require more energy efficiency and better Wi-Fi coverage.
5. The Cisco advantage
Cisco goes beyond 802.11ax with innovation such as Cisco DNA Assurance and Intelligent Capture, Flexible Radio Assignment, High Density Experience and CleanAir allowing you to build value across the network, streamline operations, and facilitate business innovation.
6. When can I expect 802.11ax in my network?
Cisco is excited about how 802.11ax will benefit future networks. However, the adoption of 802.11ax, including supporting clients and enterprise-grade access points, is still in the future. Migration to the new standard, as with all such transitions, will take place in phases over time. During this transition period and well into the future, Cisco Aironet 802.11ac Wave 2 access points will be more than capable of meeting the needs of enterprises.

Enterprise and service provider customers alike are in the fortunate position to be able to pick between two great technologies:
• IEEE 802.11ac with MU-MIMO, beamforming, and speeds from 290 to 1300 Mbps within 80 MHz
• IEEE 802.11ax with up to 8 SS and 600 to 1800 Mbps for clients (with 1024 QAM) plus additional predictability for advanced applications
IEEE 802.11ac is available today and is robust for most current customer use cases.
IEEE 802.11ax is the future of wireless LANs, but Wi-Fi-certifiable 802.11ax access points will be available only in several months. Clients (smartphones, tablets, laptops, etc.) supporting 802.11ax are also expected to be available starting in 2019. IEEE 802.11ax will provide:
• 4K/8K video at range to multiple simultaneous users (a true relief to every parent of teenagers in a household for sure)
• Ultra-High-Density (UHD) clients
• Determinism for AR/VR applications and significant power savings, especially for IoT devices
Most enterprise customers deploy new access points at the same time that they fit out a building or retrofit a space. For these customers, we recommend installing 802.11ac wave 2 access points today, because of the sheer value of 802.11ac wave 2. Consider also the infrastructure (port speeds) of the LAN and WAN networks because 802.11ac can deliver higher than gigabit speeds today, and 802.11ax can certainly deliver it tomorrow, so your investment plans for the future make this evaluation relevant today.
Mission-critical applications increasingly require determinism and predictability. IoT scale continues to outpace projections. For these reasons consideration of 802.11ax is warranted. The incremental value of 802.11ax exceeds any reasonable price differential and protects your investment without compromising operational realities today.
IEEE 802.11ax is an exciting new step for wireless LANs. This sixth generation of Wi-Fi will not only deliver higher effective speeds, but will enable new business models and use cases, including:
• Full service provider carrier offload
• IT/IoT convergence
• Real-time applications such as enterprise-grade 4K/8K video or augmented or virtual reality
As with every other recent Wi-Fi advances, 802.11ax is backward-compatible, building on existing technologies and making them more efficient. This scenario enables a graceful installed base transition with ever-increasing gains as the client base converges toward 802.11ax. 802.11ax is worth considering as soon as it’s available, even if the client density for the technology is still evolving. In the meantime, enterprise and service provider customers looking at long-term investments in wireless LANs should strongly consider 802.11ac access points.

Cisco expands Catalyst 9000 portfolio with new 802.11ax-ready wireless controller- Cisco Catalyst 9800 Series Wireless Controllers.
With the new controller, customers can, for the first time, run consistent security, automation and analytics services across wired and wireless environments by leveraging the same OS, according to Cisco. The 9800 series controller can run on premise, in the cloud—public or private—or embedded virtually on Catalyst 9000 switches.
The new Cisco Catalyst 9800 wireless controllers are the next generation of wireless infrastructure products that have been built from the ground-up for Intent-based Networking. They are designed to take advantage of Cisco Digital Network Architecture (Cisco DNA™) and Cisco SD-Access. An open and programmable operating system provides flexibility of management and automation. The Cisco Catalyst 9800 is also the first in the line to offer flexible deployment and unprecedented scale options to meet the needs of your growing organization.
The Catalyst 9800 and certain 9200 model switches will be available in the fourth quarter. The remainder of the Catalyst 9200 switches available in the first quarter of 2019.
Cisco announced two big additions to its Catalyst 9000 family: the Catalyst 9200 switch and the Catalyst 9800 wireless LAN controller.
The Cisco Catalyst 9000 Series was built from the ground up for intent-based networking. It runs on a single, open, programmable OS that powers all access and WAN products. This allows Cisco customers to turn on new software innovations faster, simplify IT operations, and lower costs.
A single software controller automates the entire network, while programmable ASICs provide unmatched investment protection. And security is embedded into the network, instead of bolted on.
By extending the Catalyst 9000 Family to wireless deployments and mid-market customers, Cisco is bringing the new era of networking to even more customers. New products include:
- New Wireless Controller: For the first time, customers can run consistent security, automation and analytics services across wired and wireless environments by leveraging the same OS. The Cisco Catalyst 9800 Series Wireless Controller can be run anywhere—on premise, in any cloud, or embedded virtually on Catalyst 9000 switches. It supports today’s wireless standards and is ready for the 802.11ax standard. It also elevates wireless services with software updates without disruption, new threat defense and advanced programmability.
- Two models are available:
- Catalyst 9800-40--scales up to 2,000 APs, 32,000 clients and offers 40 Gbps throughput
- Catalyst 9800-80--scales up to 6,000 APs, 64,000 clients and offers 80 Gbps throughput
- New Mid-Market Switch: The Catalyst 9200 switches extend intent-based networking to simple branch deployments and mid-market customers. For the first time, the mid-market gets access to the full suite of enterprise services, all at a similar price point as the previous generation of Cisco switches. Simplicity without compromise. And with the security and resiliency customers have come to expect from the Catalyst family.
- Up to 48 ports of full Power over Ethernet Plus (PoE+) capability
- Resiliency with Field-Replaceable Units (FRU) and redundant power supply, fans, and modular uplinks
- flexible downlink options with data or PoE+
- Operational efficiency with optional backplane stacking, supporting stacking bandwidth up to 160 Gbps
- UADP 2.0 Mini with integrated CPU offers customers optimized scale with better cost structure
- Enhanced security with AES-128 MACsec encryption, policy-based segmentation, and trustworthy systems
- Layer 3 capabilities, including OSPF, EIGRP, ISIS, RIP, and routed access
- Advanced network monitoring using Full Flexible NetFlow
- Cisco Software-Defined Access (SD-Access): Simplified operations and deployment with policy-based automation from edge to cloud managed with Cisco Identity Services Engine (ISE); Network assurance and improved resolution time through Cisco DNA Center
The new switches use Cisco's own ASIC and run the same OS that powers all of the company's access and WAN products.
Availability, Services and Support
- The Catalyst 9800 Wireless Controllers will be available in Q4CY18
- The Catalyst 9200L switches will be available in Q4CY18, with the Catalyst 9200 switches available in Q1CY19
- Cisco and its partners offer a full lifecycle of services to help customers streamline the journey to truly intent-based networks.
Multigigabit Ethernet (mGig), N-BASET and 802.11bz are all methods by which faster speeds can be realized (faster than 1G) using existing infrastructure wiring such as CAT-5e. The goal is to deliver up to 5 times the speed in the Enterprise without replacing existing cable structure.
Note: Although the AP 2800 does not directly support mGig, these are ideal switches for providing the power required by the AP 2800 as well.
Here are the recommended mGig switches and PoE solutions for the AP 3800.
Figure1. Cisco line of mGig capable switches
Ideally a switch supporting IEEE 802.3bz (mGig, which is also referred to as N-BASET) will deliver the fastest Ethernet using older cable systems such as CAT-5 and deliver +30W for newer PoE devices.
Figure2. Cisco Multigigabit enables speeds over 1G on conventional CAT5e cable systems
In regards to cabling structure and Cisco Multigigabit Ethernet:
- Data rates up to 1G requires 62.5–MHz bandwidth (Cat 5e is 100 MHz)
- Data rates up to 2.5G requires 100MHz bandwidth (Cat 5e is 100 MHz)
- Data rates up to 5G requires 200MHz bandwidth, which is more than the specified Cat 5e 100MHz bandwidth, but within the Cat 6 cable
The main point is that 5G operations over Cat 5e may have issues using certain cable configurations due to the fact we are using Cat 5e cable beyond the specification.
Figure3. Cisco Multigigabit cable support at rates up to 5G
*Watch for cross-talk issues in bundles or when cables are in same pipe. Keep lengths of CAT-5e between 30-50m or below when using dense cable bundles; for example, cables in a dense area like a pipe or places where five or more cables are tied in a bundle.

Table5. Cisco Aironet Access Points license portability tiers1
1 Both physical and virtual wireless controllers are in the same tier for license portability purposes. In addition, Cisco ONE wireless controllers and unified access catalyst switch are classified in the same portability tier for Cisco ONE Wireless license portability. Cisco ONE Wireless license can be ported from a wireless controller to a unified access Cisco Catalyst switch and vice versa at no cost.
We know that Cisco ONE Software suites have been introduced to provide a cost-effective and flexible way for customers to acquire software for their data center, WAN, switching, and wireless needs. Do you know how to choose the Cisco ONE Software License for your Cisco hardware? In the following part it shows you the Cisco ONE Software Device Tiering Guide that tells you more…
As described in the FAQ for Cisco ONE Software License Portability, the hardware product series and/or tier on which you have deployed your licenses determines your portability options. Licenses are portable within a product tier (for example, Cisco 2900 Series Integrated Services Routers (ISR) to 2900 Series ISR).
Devices with greater capabilities are categorized in a higher tier because they gain more benefit from the capabilities in Cisco ONE Software. You can port your licenses to a higher tier, but an upgrade fee may be involved.
Table1 describes the different equipment refresh scenarios. Subsequent tables describe the tiers for each family of hardware.
Table1. License portability use cases
Refresh a device with a device in the same tier.
Example: Cisco 2901 ISR to 2911 ISR
If a Cisco Software Support Services (SWSS) contract is in place, the software can be used on the new device.
Refresh a device with a device in a higher tier.
Example: Cisco 2901 ISR to 3925 ISR
You must pay a software upgrade fee to use the software from the original device on the replacement device.
You must purchase an upgraded Cisco SWSS contract for the new software. You receive a credit for the old support contract.
The cost is the license cost on the new device minus the license cost on the old device, at current list prices, subject to customer-negotiated discounts.
You also need to consider the cost of the upgraded Cisco SWSS contract.
Refresh a device with a device in a lower tier.
Example: Cisco 3925 ISR to 2901 ISR
You are entitled to use the software deployed on your original device on a lower tier replacement device. You retain license portability rights associated with the original device family, so you can subsequently refresh the device back to the original device family.
You can opt to downgrade the license permanently to the lower tier device family, which would allow you to renew your Cisco SWSS contract at a lower price. In that case, the license entitlement is set permanently to the lower-tier family.
None. The support contract remains with the original device family.
If you permanently downgrade, you may renew your Cisco SWSS contract at a lower price.
Refresh a device with a next‑generation device.
Example: Cisco 3925 ISR to 4000 Series ISR
In this case, the transfer depends on whether the next-generation Cisco 4000 Series ISR is considered the same tier as the existing device, or a higher or lower tier. Depending on the tier, the policies outlined above apply.
In all cases, you must migrate your software licenses to a next-generation device before your older device reaches end of support. At this stage, your Cisco SWSS contact will have expired and you will not meet the portability criteria.
The tier of the next-generation device determines the cost. Depending on the tier, the policies outlined above apply.

More Detailed STEPS & Examples of Cisco Mobility Express Guide
The Cisco 2800 and 3800 Series Access Points target customers requiring support for mission-critical and best in class applications.
The 2800/3800 embodies ClientLink 4.0, an innovative antenna technology comprising four transmit radios and four receive radios called 4x4 in a Multiple Input Multiple Output (MIMO) configuration and supporting three spatial streams (3SS), together referenced as 4x4:3. Using this type of antenna system along with additional Modulation Coding Scheme (MCS) rates supporting up to 256 QAM and up to 160 MHz channel bonding, rates of up to 5 Gbps can be supported.
ClientLink 4.0 uses these features along with an additional antenna (N+1) to allow for beam-forming for all 802.11a/g/n/ac and now ac Wave-2 clients including those supporting 3 spatial streams.
MultiGigabit Ethernet, also known as MGig or NBaseT, provides multiple gigabit uplink speeds of 2.5 Gbps and 5 Gbps in addition to 100-Mbps and 1-Gbps speeds. All speeds are supported on Category 5e cabling for an industry first, as well as 10GBASE-T cabling. This is huge achievement which can result in significant cost savings for large campus network. No longer are you constrained to 1Gbps, nor do you have to worry about running new cabling in order to support the new speeds.
Cisco Catalyst Multigigabit technology solves these challenges on their newer Catalyst 3850, 4500E and 3560-CX switches, with the 3800 Series access point taking full advantage of the single-wire MGig connection. This is an incredibly important consideration for 802.11ac Wave 2 implementations, and should be reviewed before any deployment.
Peter Jones, Principle Engineer with Cisco and NBASE-T Alliance chair, gave an impressive presentation at TFDX earlier this year, detailing the technical achievements engineered to overcome this obstacle of capacity.
Expansion Module Slot
The 3800 Series AP sports a module port for future expandability. Physical modules can be fitted for value-adds like advanced security or hyperlocation technologies.
