For several years, certainly as long as I have been writing this blog, I have been hunting for a better cordless IP telephony solution for my home office. Cordless mobility is increasingly a critical feature for home office and small business users. While we have a satisfactory solution in place at the moment, there’s certainly room for improvement.
Siemens, a multi-national company headquartered in Germany, has a new subsidiary called Gigaset US specifically to market some of their range of consumer electronics in North America. This new company is headquartered in Dallas, Texas.

The CATiq blog as a press release from RTX Telecom about the release of a new DECT/CATiq 2.0 USB dongle. The release states that the device is basically a DECT/CATiq base station with a USB interface. That makes it an easy way to add cordless telephony capability to devices that might not otherwise have such capabilities.
This also makes it an excellent tool for testing DECT/CATiq systems. Such a tool was used by the DeDected group that reported on the state of DECT encryption at the CCC event in December 2008. The hardware that they used in their experiments was not widely available outside of Europe, and has since been discountinued.
Over at VoIP Supply’s VoIP Insider Cory Andrews poses a good question, ” When Will HD Audio Come to Mobile Phones?” He frames it up in the context of having first hand experience with enterprise class wideband hardware like the new Polycom VVX-1500 Media Phone, but then recasts the question in the mobile space.
With 3G here and 4G coming, the bandwidth is certainly there to support HD calling on mobile devices. Seems all that is currently lacking is a traditional carrier or mobile VoIP provider and a handset manufacturer with a wireless device that supports G.722 or alternative wideband codecs. I wonder if there are existing mobile phone devices with a large deployed base that could be made “HD capable” via firmware update?
I’m certainly not an expert in all facets of the technology involved, but I have been investigating wideband for some time, and tapping many sources along the way. After a while all the little pieces of information start to form a more complete picture of what’s involved.
