Emulating MIMO for Testing

By Glenn Fleishman

Azimuth Systems releases MIMO emulator to help test new devices: A robust testing suite can help manufacturers tweak designs before they reach production. Azimuth has added MIMO hardware and capabilities to its product suite so that engineers can examine interference and propagation issues in environments that emulate real-world use.

New 802.11n Proposal

By Glenn Fleishman

Everyone but Airgo has dogpiled on the Enhanced Wireless Consortium: The new group comprised of Intel, Atheros, Broadcom, and 24 other manufacturers and chipmakers has a merged proposal for Task Group N. Since this has become a mainstream issue, we’re covering it over at Wi-Fi Networking News. Read more there.

Chipmakers Present Their Own Secret 802.11n Plan

By Glenn Fleishman

A schismatic group of companies secretly working outside the IEEE 802.11n group’s process may submit a new proposal Monday: reports that Intel, Broadcom, Marvell, and Atheros have a new plan. All but Broadcom are also part of TGn Sync; Broadcom was part of the WWiSE proposal. The future of 802.11n has huge market consequences, and there’s more than a whiff of collusion when four giant semiconductor makers engage outside a standards process.

Still, by presenting their proposal, they may take potential prosecution off the table. But it’s unclear whether if their proposal isn’t accepted that they go back to the table or walk off and start a trade group as happened with 802.15.3a and UWB (ultrawideband). Intel leads the WiMedia Alliance (formerly the WiMedia Alliance and the Multi-Band OFDM Alliance).

Ruckus and Its CEO

By Glenn Fleishman

Interesting story about Ruckus multiple-antenna technology and Selina Lo, its CEO: The company changed its name as it introduced consumer-oriented hardware to shift its business away from competing in the commodity, already-overcrowded market of supplying consumer Wi-Fi MIMO add-on to video delivery. They’re already shipping devices to PCCW, the giant Hong Kong telecom provider.

The technology has to take off in the home, and it’s not compatible or interoperable with anything else. Still, it’s a great idea, and consumer buy odd technology if it works—and often when it doesn’t (viz., Atheros’s semi-abandoned Turbo dual-channel bonding mode).

Selina Lo is a hoot; I’ve interviewed her, and it’s always a pleasure to talk to someone that frank, although she freely acknowledges in this article she can offend people through her “rough” and “tough” attitude.
