I just got an email invite for CES which discusses a new Motorola Peer-to-Peer two-way adaptor, which I cannot find anywhere in Motorola's press release archives, i.e. Motorola Mediacenter - Press Releases
Nevertheless, I thought I would share the appropriate excerpt of the email message since it involves peer-to-peer (P2P), VoIP, FRS, and GMRS.
If I read this email correctly, it sounds like you hook up this adaptor to your PC and then using one of Motorola's two-way radios, you can communicate with your PC (via the adaptor) which then initiates a VoIP call to the 2nd two-way radio you are trying to reach. This helps get around the 5 mile limit on two-way radios as well as other benefits. Here's the excerpt:
Motorola New Peer-to Peer Two Way Adapter - lets you go beyond the 5 mile barrier. You can now talk with friends and family almost anywhere. Radio users can talk for free over the Internet to anyone else on the network by connecting almost any FRS or GMRS two-way to a computer and then transmitting the user's voice over VoIP. The users send voice data packets to and from each other, directly, in a true peer-to-peer fashion resulting in an evolutionary next generation of Motorola's industry-leading hand-held two-way radios.
If anyone finds out more info on this product, feel free to post a comment. It may even be an upgrade of an existing product that I was unaware of, but I doubt it.
