There are a few ways in which the latency can be lowered -- for example, by using asynchronous routing whereby inbound packets are received via the high-throughput, high-latency satellite link, and outbound packets are sent via a low-throughput, low-latency link, such as a modem. However, the impression I have when looking at the closednetworks.com website is that they are not utilizing satellite links, but rather fixed-wireless links within the city. > It would also be nearly useless for IP Telephony.
