People can connect as many devices to the LAN as they want, and they can plug in any of the popular firewalls and routers sold for cable or DSL modems. WLL has advantages over satellite broadband because of its lower transmission delay. Also, the services typically don't discriminate against certain applications, like Napster, for example. And WLL service is likely to improve as the technology matures. Breezecom and Western Multiplex, for example, are delivering next-generation radios with greater bandwidth and more capabilities to manage the connections, so that carriers can offer guaranteed levels of service.
Price is another matter.
As WLL proliferates, equipment prices should fall. Thus, some of the largest potential competitors in the WLL space are introducing service in areas already covered by one of the wired broadband flavors. Afterword by cw. Frank talks about the higher cost of Wireless Broadband. That's not the case with TerraNovaNet.
