Hi Peter, I did not intend to imply that space itself was an impediment to IP, rather, that when the TD venture was formed IP was not as pervasive as it is today. Hence, the model that was developed didn't take IP into account as much as it would today. TD's LEOs would not introduce egregious latency, so they would not be disruptive to IP flows, as you suggested. But GEOs, being much higher up, are not as kind and often require tweaking of the IP stack in order to optimize transaction/turn times. I'm not suggesting that this is an imperative, only that sometimes it's done to improve performance due to the greater propagation times that are encountered. Correct me if I'm wrong about this. FAC

MeshNetworks Introduces Its Multi-Hopping Software for 802.11 [FAC: We discussed MeshNetworks here briefly several days ago (msgs 4959, 4960). The following is from convergedigest.com ] MeshNetworks, a start-up based in Maitland, Florida, introduced a software system for extending the range and robustness of existing Wi-Fi networks by adding multi-hopping peer-to-peer capabilities to off-the-shelf 802.11 cards. The MeshLAN software transforms wireless LAN cards into router-repeaters, which enhances and extends the wireless reach of each subscriber in the network. A MeshLAN-enabled Wi-Fi user who is out of range of an access point can hop through one or more users to reach the access point. Furthermore, the MeshLAN routing intelligence will automatically shift transmissions from congested access points to uncongested ones. The software leverages the built-in peer-to- peer mode included in every 802.11 card. MeshNetworks said its software will also work with 802.11 variants, including 802.11a, 802.11b, and 802.11g. meshnetworks.com MeshNetworks, February 6, 2002 In January, MeshNetworks was granted an experimental license by the FCC for demonstrations of its mobile ad hoc peer-to-peer broadband technology in both the 2.4 MHz and 5.7 MHz bands. The FCC's action enables MeshNetworks to conduct large-scale demonstration networks in Orlando/Maitland (FL), Washington, DC, Denver/Boulder, and Dallas/Fort Worth. The license also grants MeshNetworks the ability to simultaneously demonstrate small- scale networks in five different locations anywhere in the US. In November 2000, MeshNetworks secured $26 million in its second round of financing. MeshNetworks is working on a chipset for wireless communications based on ad hoc Quad-Division Multiple Access (QDMA) technology. The concept would enable mobile devices, such as cell phones and PDAs, to network through each other in addition to cell towers so that the devices become part of the network. Investors include Redwood Ventures, ITT Industries, BancBoston Ventures, Patricof & Co. Ventures, and 3Com Ventures, among others. MeshNetworks was founded by Milcom Technologies to commercialize wireless technology developed for the Department of Defense for a battlefield handheld terminal supporting voice, data and video communications.
