Hardware And Methodology, Explained
Here’s a less pretty (but more informative) view of our test environment:
As you can see, we conducted two line-of-sight tests, one at 10 feet between the access point and client and another at 70 feet. The map shows desk areas and partitions within the line-of-sight path, but as you can see below, no obstructions were actually in place. A third test at 100 feet was done with a large kitchen/break area blocking the direct data path.
We had a wired side of the network, attached to which was the access point being tested. For all tests, we used an AP and whatever network infrastructure was necessary to support it. For example, the Ruckus and Aruba APs used wireless controllers, while the HP and Apple did not. Attached to this was a data server running an IxChariot (version 7.1) endpoint, a program that drives data back and forth and reports results back to the console, which was running on a separate wired network node. We ran another IxChariot endpoint on the wireless client connected to the AP.
Specifically, our hardware was as follows:
- Apple AirPort Extreme: Dual-band 802.11n (3x3:2), standalone, version 7.5.1
- Aruba AP125: Dual-band 802.11n (3x3:2) with Aruba 3200 controller running ArubaOS (ver. 220.127.116.11)
- Cisco Aironet 3502i: Dual-band 802.11n (2x3:2) with Cisco 4402 controller (ver. 18.104.22.168)
- HP E-MSM460: Dual-band 802.11n (3x3:3) standalone running version 22.214.171.124-01-9514
- Meraki MR24: Dual-band 802.11n (3x3:3) running Meraki Enterprise Cloud Controller
- Ruckus ZoneFlex 7363: Dual-band 802.11n (2x2:2) with Ruckus ZoneDirector 1106 (version 126.96.36.199.38)
We brought in the Apple for two reasons. First, we wanted an example of a good consumer-grade router/access point as a basis for comparison against enterprise gear, because a lot of consumers and small business people remain baffled by the massive price gap between the two groups. Second, in the last couple of router roundups we did at Tom’s Hardware, readers complained that we omitted Apple. Well...here you go.
Of these six APs, only Meraki and HP employ triple-antenna, three-stream (3x3:3) configurations. In fact, these were the only two 3x3:3 APs we were able to find on the market in time for testing. The Aruba AP125 is a fairly standard model for the company, and it’s been around for a while. Likewise, Ruckus’s 2x2:2 ZoneFlex 7363 is fairly mid-range within the company’s lineup. The Cisco 3500 is the networking titan’s current high-end AP.
We would also like to point out that most of the access points reviewed here use omnidirectional antennas, as discussed extensively in our precursor to this piece.. Ruckus, which we showed last time, and Meraki, shown here, are two exceptions. To the untrained eye, Meraki and Ruckus seem to use very similar designs, each employing directional antennas in an effectively circular pattern. However, Meraki is using planar inverted F antennas (PIFAs). The larger ones are for 2.4 GHz and the smaller are for 5 GHz, thus leaving only three antennas for each band. We’ll see how this spin on the circular design performs in a bit.
