"Fiber to the home would be unnecessary."

Posted on by • Tagged , • Leave a comment

Clearwire???s 40 MHz bandwidth will support peak speeds of 168 Mbps, twice as fast as anything Verizon, AT&T, Sprint and T-Mobile can throw it, according to John Saw, CTO of Clearwire.

LTE Advanced supports 8??8 MIMO downlink antennas. With a 40 MHz pipe, each sector might support 600 Mbps, or 30 subscribers streaming at 20 Mbps (times 3 sectors) ??? that???s wireless cable. Multi-casting might transmit a base of 6-8 local channels at little or low cost. Fiber to the home would be unnecessary.

“White space” viable for rural broadband – report | InternetNZ

Posted on by • Tagged , , , , • Leave a comment

A just-published report on radio spectrum “white space” has found that the technology is a viable alternative for getting high-speed broadband out into rural and remote New Zealand communities.

White space refers to radio spectrum frequencies allocated to a broadcasting service but are not used locally.

The report – written by telecommunications consultant Jon Brewer – explores a number of technology and regulatory issues, as well as several practical uses and trials of white space technology.

Brewer notes that approaches based on “white space” are inexpensive, lightweight and can provide more effective broadband coverage in geographically-challenged parts of the country.

In the report he highlights the potential of white space for three New Zealand rural communities – Parikino in the Wanganui District, Pourerere in Central Hawkes Bay and Clova & Crail Bays in the Marlborough Sounds.

The report was funded by InternetNZ (Internet New Zealand Inc) as part of its Community Projects Funding Round, held last year.

Vortex radio waves could boost wireless capacity ???infinitely???

Posted on by • Tagged , , • Leave a comment

It is hard to put into words just how significant Thide???s discovery could be. If the vortex preserves other aspects of wireless communications, such as multiplexing, then in the short term we could be looking at a wireless spectrum that can carry 10 or 20 times as much data. In the long term, as our understanding of orbital angular momentum grows, our wireless spectrum could effectively be infinite. To be honest, this is such a huge twist for wireless communications that the full repercussions are not yet known.

New standards make using carrier Wi-Fi super easy

Posted on by • Tagged , , , , • Leave a comment

The IEEE technical standards body is developing 802.11u and the Wi-Fi Alliance has developed its Hotspot 2.0 initiative to further define and implement the use of the new standard. The new standards will essentially define how hot spots are discovered by devices and also provide a uniform mechanism for allowing subscribers to sign on to the networks, without the user selecting a particular network or entering a password. It also provides WPA 2 security to ensure that subscribers have the same level of security they expect when they’re on a carrier’s cellular network.

AT&T’s Randall & Stankey: Wireless data growth half the FCC prediction

Posted on by • Tagged , , • Leave a comment

With growth rates less than half of the predictions, a data-driven FCC and Congress has no reason to rush to bad policy. Wireless technology is rapidly moving to sharing spectrum, whether in-building small cells, WiFi, White Spaces, Shared RAN or tools of what the engineers are calling hetnets – heterogenous networks. The last thing policymakers should do is tie up more spectrum for exclusive use; shared spectrum often yields three to ten times as much capacity. 
 Bad compromises on the video spectrum are unnecessary because plenty of spectrum is unused. That includes the 20 MHz that M2Z would be building out today if Julius hadn’t blocked them; the 20 MHz the cable companies are sitting on and want to sell to Verizon; and the 30 MHz or so Stankey identifies as fallow at AT&T.

Another case for the removal of exclusivity and more general spectrum allocation. Making a decision now about what’s best denies the flexibility the likes of 802.22 et al can provide through smarter, cognitive, approaches.
