AirMagnet breaks new ground in wireless spectrum analysis

Everyone needs a Wi-Fi spectrum analyzer, but there are times when analyzing cellular spectrum is also essential. Fluke Networks' new AirMagnet Spectrum ES provides a broad range of capability at a very attractive price. Spectral analysis, a longstanding fixture in electronics and manufacturing test, and, more recently as a valuable tool for understanding coverage, interference, and other elements of Wi-Fi, is the art and science of extracting meaning and insight from wireless systems at Layer 1 -- radio waves.

Averail Access aces mobility management test

Enterprise mobility management (EMM) can encompass a broad range of functions, from managing mobile devices, to applications, expenses, personnel, and policies. But perhaps the most important aspect is mobile information/data/content management, tracking the distribution and usage of sensitive organizational data, as well as ensuring appropriate security and policy compliance.

Tips for buying a three-stream access point

The decision to buy a three-stream access point (or likely, a whole lot of these) in an enterprise environment is more complex than throughput alone. You need to begin with overall IT requirements, objectives, planning cycles, and operational strategies.

A note on nomenclature

Wireless LAN devices (access points and clients) supporting (up to) three spatial streams are often denoted as "3x3" devices, referring to the minimal number of transmitters and receivers required to make this particular configuration of MIMO work. But there is so much variability in terminology here that a standard nomenclature is required.

What you need to know about 802.11ac

A question we're hearing with increasing frequency concerns the upcoming 802.11ac standard, which promises to do to 802.11n what .11n did to .11g. While the IEEE 802.11ac standard likely won't be completely finished before the end of 2013, and, while the Wi-Fi Alliance similarly has issued no interoperability criteria for 802.11ac, consumer-grade products claiming compliance with the aforementioned 802.11ac standard could be on store shelves as soon as the middle of 2012.
