tainor: Thanks for the information. If Birdstep’s switching technology is based on the fastest available net and then automatically connects to it, it will not infringe on Calypso’s patent. This is also the official stance of Calypso.
This technology might work great for data but might not be sufficient for voice: A Wi-Fi switching cell phone based on Birdstep’s technology would automatically establish a connection to the Wi-Fi network as long as it is faster than the cell network. We all are familiar with what a cordless phone sounds like when you are too far away from the base station. Birdsteps’s technology would initiate the switching process at any distance even if this speed is not sufficient for voice yet. This might result in static and scratching noises which you are trying to avoid in a phone call. That’s where Calypso’s technology comes in: It patented claim is that it only establishes the connection once you within a certain distance (predetermined parameter) of the base station. That way you make sure that the quality of service is sufficient for voice. That’s where investors see the value in Calypso’s patent.
