Wi-Fi experts from Cisco, Aruba, Ekahau, Extreme and Mist share best practices for Wi-Fi performance optimization, focused on three major phases of large-scale Wi-Fi installation: planning and pre-installation, post-installation performance testing and verification, and troubleshooting Wi-Fi performance issues.
Wi-Fi experts share best practices for establishing and maintaining optimal WLAN performance
Millimeter-wave technology is becoming less expensive and easier to deploy, making it a candidate for many wireless connections, including backhaul, personal area networks, LANs and even mobile devices.
From amplifier to wireless network topology, find concise definitions of wireless terminology
No advance in information technology in the past six decades has offered a greater range of quantifiable benefits than has virtualization.
Farpoint Group tests whether multi-user, multiple input, multiple output (MU-MIMO) wireless technology delivers on its promise to boost Wi-Fi system capacity and how much gain can be expected.
With a wealth of experience in the field, Friday explains how his company is inventing and bringing to market virtual BLE beacons.
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.
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.
PowerCloud Systems has released a cloud-based Wi-Fi solution that fills the gaps between residential products that lack management and features, and enterprise systems that can be overkill in smaller organizations.
The rapid adoption of 802.11n has become a significant milestone in the history of wireless LANs. The MIMO-based technologies used in most 802.11n systems provide enough throughput, reliability, and rate vs. range performance to effectively remove the last major barriers to the broad adoption of WLANs in the enterprise.
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.
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.
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.
