Voice Over IP On Wireless Mesh
infractor writes "ZDNet is reporting that the Linux based LocustWorld Mesh system now has SIP routing at every node. The LocustWorld boxes have been widely used in community broadband projects where DSL is not available, so successfully that they have been seen as a threat to next generation mobile networks. With the addition of VoIP support, these mesh networks can now compete with the telcos on voice as well as data services. More details here."
With the addition of VoIP support, these mesh networks can now compete with the telcos on voice as well as data services.
I would have to disagree with that comment. Yes, these networks can now provide voice services, but they cannot effectively compete. In reality, wireless VoIP is still being developed and will most likely not be of acceptable quality for another year or so. Mainly, latency is the biggest issue to be conquered at this time. I think until they are able to reduce latency times significantly in these applications, it won't be widely accepted. It's just too frustrating when theres a couple seconds in between speaking and hearing a response from the other person.
Furthermore, while a mesh network can still carry a high data rate, the high number of hops to a wired connection from some locations along the network could make talking over VoIP rather unbearable. I imagine that on a larger mesh network you could experience latency upwards of 1000 ms.

Compete? Maybe not. Remember when NPR discussed this and one of the callers started having problems - right in the middle of his praise for VoIP?
That said, I'm anxious to find an inexpensive way to replace my $90 cell, $50 broadband cable, and $40 landline. If I can cut these bills down significantly (by using my broadband to provide my landline) I'd be happy. And I'd bet that most bill-paying consumers would be too.
