IEEE Supports 802.11n Proposal
Jan 20, 2006 - Mobile Radio Technology reports that an IEEE task force unanimously voted in favor of the 802.11n draft standard offered last week by a joint-proposal team led by the Enhanced Wireless Consortium (EWC). Although the 802.11n draft probably will not be ratified as a standard for about a year, industry observers have said they expect products based on the draft version of the standard to appear on the market this summer.

The 802.11n standard is expected to generate maximum data throughputs of 600Mb/s, making the wireless transmission of even high-definition video content between devices possible. In addition, the range of 802.11n is expected to be much greater than current Wi-Fi standards--up to 1,500 feet--and the new standard will be designed to operate at unlicensed frequencies in the 2.4GHz and 5GHz bands.

Mobile Radio Technology like Radio magazine is owned by Prism Business Media.

Ham Radio Antarctic DXpedition to Use Iridium Phones
Bethesda, MD - Jan 19, 2006 - Iridium Satellite is supplying mobile satellite phone systems for a group of amateur radio operators who are undertaking a DXpedition this month. The purpose of the DXpedition is to establish up to nine temporary radio stations on a remote uninhabited ice-bound island near Antarctica.

The radio site will be operational on Peter I Island for about two weeks in February. During that time, ham radio operators around the world will have an opportunity to log calls to the station.

The Iridium satellite phones will allow the team to stay in touch with home, obtain weather forecasts, provide daily uploads of log information and updates from the island. Updates will include photos and possibly video clips, which the DXpedition group will post to its website at

Emmis' Smulyan Talks about HD Radio
Indianapolis - Jan 16, 2006 - Emmis Communications posted a Q&A with its CEO Jeff Smulyan about HD Radio, the HD Digital Radio Alliance and more. We have selected the portions that are relevant to the technical side of radio.

Q: How is the HD Digital Radio Alliance selling HD Radio to consumers and auto makers?
A: Emmis is one of the founding partners of the alliance. The idea is to facilitate the rollout of HD Radio by ensuring a wide array of free, over-the air programming, making consumers aware that HD Radio brings them CD-quality sound, and pushing to bring more HD receivers to market at reasonable prices. To that end, members have agreed to launch new, commercial-free HD side channels, run spots on main stations promoting the benefits of HD radio and lobby car makers to install the receivers in new cars.

Q: One would imagine that formatting the HD side channels would be fraught with peril--how do you see those things being worked out where everyone is happy?
A: It really hasn't been difficult at all. We beta tested format selections for side channels with both alliance and non-alliance members a few months back and were delighted at how many unserved niches and format offerings programming directors came up with. The selection process for both the beta test and actual markets has gone incredibly smoothly, mainly because broadcast companies and their programmers have treated these side channels as an opportunity to provide listeners with the kind of diverse programming that many think is limited to pay radio. New, free format choices. That has a lot of potential to fuel interest in HD receivers.
