[Asterisk-Users] Wireless LANs and Asterisk

[jurgen]

Hi Mike,

This is interesting - it's something that I've been considering doing
for the Asterisk rollout at my company. We don't have enough Ethernet
ports and I'm not thrilled about the expense of re-wiring the place.

Have you tried D-Link's dual-channel gear for even more bandwidth, or
do you feel that bandwidth is not really a problem? How resilient is
802.11g against interference from other sources? Microwave ovens,
gigarange phones, etc.

Thanks for reporting your success here to the list, just proves I'm
not alone with my funny ideas.
