I doubt they would be there for a VOIP event. Their product roams between cellular and wi-fi, or short range wi-fi to wi-fi. I asked Mr. Schilling to express opinion about Birdstep 2.0. He said Birdstep doesn't infringe on their patent because of the above. Birdstep roams between wi-fi networks only.
Ok, techies, tell me if I got this right and fix my definitions where I've got them wrong. I've read so much in the last few weeks it's all running together in my head.
VOIP = Voice over Internet Protocol, allows phone calls over data lines in packets, requires hardwire cable, some providers require broadband connection
Wi-Fi = Wireless Fidelity , a local area network that uses high frequency radio waves to transmit a very short distance, a few hundred feet? using 802.11b protocol (had to google that)
Wi-Max = Wireless Maximum? (no clue), still uses radio waves, up to 10 mile range if antennas are directly facing each other, new technology allows shorter (2-3 miles) range if antennas aren't exactly aligned. Raging bull had an article of how it saved the day for a company conference after the cable lines were cut.
Cellular = Refers to geographical sections called cells, the cell phone transmits by low frequency radio waves in the 800 Mhz band within cells, with a call moving from base station to base station (old terminology) or between cpu's/switches (new)
Has anyone gone back and reviewed the rest of the competition's plans as pertaining to seamless roaming, so we know what they're planning to roam between? Given a successful prototype, we still need to compare apples to apples.
