Why will IEEE 802.11ac Change the Wireless Experience?

PART II

Cabling and Wireless Installation Articles 3-23-2015

Last year I wrote an article (May 2014 http://oberonwireless.com/news/blog) on IEEE 802.11ac compliant products –suggesting that products built to this standard would feature “wired like” speeds, data rates beyond 1 Gig, unprecedented user density, scalability in large venues, and better client battery life. All this new capability is provided by larger swaths of bandwidth available in the 5 GHz band and sophisticated modulation and coding schemes enabled by advanced signal processing techniques. I described in that article that 802.11ac is being rolled out in two waves, actually referred to as Wave 1 and Wave 2. I also described that Wave 2 products will engage, for the first time, Multi-User Multiple Input-Multiple Output, or MU-MIMO, technology. MU-MIMO has the ability to significantly advance data throughput. In this article I will discuss Wave 2 data rates in more detail, compared to Wave 1 and prior technologies, and implications on the wireline network. I will also attempt to make a forecast of requirements for planning cabled infrastructure into the next decade.

Positioning a Wireless Router and Other Networking Components with Oberon’s 1016 Wireless Network Cabinet

In a corporate environment, Internet access and network connectivity are a vital part of day to day business. Even minutes of down time leads to lost productivity. As such, networking components are always locked and secured in a telecommunications room. The Wi-Fi and wireless components of the network present a dilemma, however, in that the wireless end points (access points) need to be out in the open workspace (rather than in a telecom room), yet still secured. In a corporate or campus environment, the access points are often locked and secured in Oberon wireless access point enclosures, providing the dual functionality.

Why will IEEE 802.11ac change the Wireless Experience?

Products built to the new IEEE 802.11ac amendment feature "wired-like" speeds, data rates beyond 1 Gig, unprecedented user density, scalability in large venues, and better client battery life. All this new capability is provided by larger swaths of bandwidth available in the 5 GHz band and sophisticated modulation and coding schemes enabled by advanced signal processing techniques. Among the technologies offered by the latest 802.11ac products is Multi-User Multiple Input Multiple Output or MU-MIMO. MU-MIMO is the ability of the wireless access point (WAP) to engage multiple clients simultaneously. Of course, prior generations of WAPs could engage multiple clients "simultaneously", but only in the sense that multiple clients could be associated with a WAP and be communicating with it, but only one at a time. The new MU-MIMO will permit multiple client devices to be communicating, truly, at the same time.

Wireless Networks in Healthcare: Infection Control Risk Assessment (ICRA) procedures and TIA-1179 Healthcare Facility Telecommunications Infrastructure Standard

The Joint Commission, which is the body that accredits healthcare facilities, has specified that facilities should establish Infection Control Risk Assessment (ICRA) procedures for mitigating the spread of infectious disease and agents. Recognizing that the air-handling (plenum) space above a suspended ceiling may accumulate dust, the risk assessment procedure may control access to the to the air-handling (plenum) space above suspended ceilings.
