This reminds me of the ad-hoc network capability that's built into every machine made for the "One Laptop Per Child" project (http://one.laptop.org/). I assume that it's a form of "mesh" network, and I'm curious how many nodes it can handle, and if there is a relay or "help me" capability in the network that would connect a handset that was out of range to a tower via another (or two or more) handsets.

It could probably also be set up in a "Broadcast" mode where each handset could act like a CB radio on a common channel - something that could be handy in a disaster situation. If it is only a software app that can be implemented in most of the current handset platforms easily then it could well be of value when all the existing infrastructure "goes dark". -- Regards, David.

Two months with no resolution by the old company. Two months with no resolution by the new company. Then I take a shot in the dark and inadvertantly fix it when they couldn't. It wasn't the last thing they tried. I'd say that they NEVER identified what would fix it. It just shows that these VOIP companies hire budget people and no one with real troubleshooting skills. They make no effort to bring any of their people up to speed to resolve the more difficult problems. That's the sign of inferior management. The VOIP industry is giving itself a very bad reputation.

IMHO: Subscribers are willing to tolerate this lousy service, partly because they don't have a frame of reference to expect better, and partly because they like the cheaper price. The gold standard used to be the service level from the Bell System, but since Divesture, the Baby Bells' service quality has declined as they cut costs to be competitive. (Ironically, people expected more from the old Bell System since it was a monopoly and provided end-to-end service. Today, people don't blame the phone company if their ac power goes out and their phones do not work as a result.) As mentioned, after the hurricane my neighbors were quite surprised that I had still had phone service while they lost theirs. Further, people do so much of their talking on cell phones which have inferior voice and connection quality. To me this all illustrates the lower service expectations. I suspect that if company attempted to provide today a high level of service quality and first-rate customer support, it's prices would be so high that it simply couldn't compete in the marketplace. This isn't just telecommunications, but banking and other services, too.
