The new 802.11ac is not a stranger in today’s Wi-Fi world. It is the emerging standard from the IEEE and couples the freedom of wireless with the capabilities of Gigabit Ethernet. Yes, 802.11ac is a faster and more scalable version of 802.11n.

Now, the new 802.11ac wireless networking standard (it was approved in January 2014) is getting all of the attention from device manufacturers.

The IEEE 802.11ac standard supports up to a total of 8 spatial streams, 160 MHz channels, and 256QAM modulation for a total potential interface rate of up to 6.93 Gbps (8 spatial streams, 256 QAM, 160 MHz channels). When compared against the IEEE 802.11n max physical rate of 600 Mbps, the differences in speed are considerable. The advances in antenna technologies and other enhancements, such as beamforming, will also affect signal strength and the maintenance of speed over distance will increase as well.

In this article we will take a look at the basic elements to look for in an 802.11ac access point (AP) and the currently available enterprise 802.11ac AP offerings from the top four market leaders (Cisco, Aruba, HP and Ruckus Wireless).

What to Look for in 802.11ac Access Points?wireless-witch-should-you-buy-an-802-11ac AP

If you want to select an 802.11ac access point, what to look for in it? Yes, there are a number of different feature offerings that are supported, in one way or another, for all of the available 802.11ac devices. Some of these things include: support for Wave 2, enhanced beamforming, intrusion protection, spectrum analysis/noise reduction, roaming optimization, and antenna options.

Let’s take a look at these features in more detail.

Support for Wave 2

The next best thing coming in the wireless space is the introduction of IEEE 802.11ac Wave 2. This is the name that is currently given to the next distribution push into the standard (it’s actually an amendment to the standard). The IEEE 802.11ac standard does support up to 8 spatial streams using 160 MHz channels; this will offer a considerable upgrade in speed even from the existing IEEE 802.11ac offerings. As of this writing, the best enterprise grade AP offerings have support for up to 1.3 Gbps of physical line speed. The first evolution of Wave 2 is going to support 1.7 Gbps using 160 Mhz channels; this is currently supported on some bleeding edge products using the Quantenna chipset, just not in the enterprise space. But the full Wave 2 amendment supports a push from the previous maximum physical rate of 3.47 Gbps to 6.93 Gbps.

Another big addition with Wave 2 is support for multi-user MIMO (MU-MIMO). This will be a big upgrade in terms of the usability of wireless LAN networks. In current wireless LAN networks, only a single radio device is allowed to communicate on the network during any given time (like an Ethernet Hub); with MU-MIMO, multiple radio devices will be able to access the system at the same time (like an Ethernet Switch).

Beamforming

The AP vendors mentioned in this article support some form of beamforming. So what is beamforming? Well at a high level, beamforming allows the transmitter and MIMO receiver to work together to achieve the best signal possible by using multiple antennas to transmit and receive signals. The point is to effectively increase the signal strength by attempting to prevent signals from cancelling each other out at the receiver. This is done through a number of different technical methods, the most relatively simple one being the alteration of the signal gain and phase.

As with everything in business, the actual results of a given solution can significantly differ from what the vendor promises. Make sure to take the time to test multiple vendors in the target environment to ensure the expected performance is achieved.

Wireless Intrusion Protection

As with every other piece of networking equipment, security is extremely important. Most vendors support some type of wireless intrusion protection, typically including support to detect rogue access points and clients. While this may be an add-on to some vendor’s product lines, it should be a major consideration in product selection.

Spectrum Analysis/Noise Reduction

Anyone who has ever implemented a wireless network is familiar with what noise can do to the network’s availability and capability (is the microwave running?). Most of the vendors have their own features that are intended to reduce both the noise created by their solutions and external noise that affects their solutions. This is done through a combination of both active and passive noise environment detection; based on the results from this added information the signal can be modified to best meet the requirements of a specific environment.

Roaming Optimization

In enterprise environments, it is vital that devices are able to work together to provide the best signal possible to clients as they move throughout the environment. This includes not just the ability for clients to have a signal, but also getting the best possible signal as they move. Each vendor has its solutions for this, but they should be tested to ensure that the performance expected is delivered in your environment.

Antenna Options

In the world of wireless, one thing that can never be overlooked is the selection of available antennas for a specific product. Since the environment that a wireless network must work within is almost always different, the ability to adapt a solution to use multiple types of antennas to achieve good performance is vital.

How to Select the Best 802.11ac Access Point? As with any wireless gear shopping experience, there are a number of different options available and the selection of the best solution is specific to the target environment and the requirements of the situation. If you’re considering a move to 802.11ac gear, take a look at the available options discussed in this article and compile that with the requirements of the intended environment. Then choose a few vendors that fill those requirements the best and test the access points in the environment to ensure their performance before purchasing.

Also keep eyes out for new devices coming to market. The IEEE 802.11ac standard is still fairly new, which means more new Wi-Fi gear is on the horizon. Please look forward to it.
