Calypso Warns It Will Enforce Roaming Patent
By Mobile PIpeline News
Calypso Wireless said Wednesday it is contacting mobile device vendors to warn them that it will enforce a patent that covers roaming between cellular data systems and shorter-range networks such as wireless LANs.
A number of vendors have said they will release mobile devices that work both with wide area wireless data networks such as those based on EDGE and CDMA technology shorter-range networks such as wireless LANs. The patent, which was granted last week, covers a method of seamlessly roaming between the two types of networks, Calypso said.
The Florida-based company said in a statement that the patent "could have a significant and immediate impact on the development of the industry, as well as major implications on the way that OEMs such as Nokia, Ericsson and Motorola do business."
The company said that it already is negotiating with one major manufacturer to license its roaming technology. It claimed, however, that the patent was a win-win proposition because it adds significant capabilities to wireless devices.
"Our technology could dramatically boost overall wireless handset sales, and change the industry's growth projections globally," David Davila, Calypso's president and CEO said in a statement. "By teaming up with us, OEMs will now be able to manufacture and market such devices and dramatically boost their sales."
