there was a group a couple years ago that did linux drivers specifically to resolve this. Basically they have 2 cards one is always Tx one is always Rx, and they can do full duplex that way. The goal was with 802.11 (wifi) specifically and for a mesh layout specifically (although it could be used with a single node). 802.16 (wimax) supports both TDD (half duplex) and FDD (full duplex), so depending on what you are doing specifically you may not have to do anything sneaky like the aforementioned linux drivers. -- Trixter http://www.0xdecafbad.com Bret McDanel Belfast +44 28 9099 6461 US +1 516 687 5200 http://www.trxtel.com the phone company that pays you! _______________________________________________ --Bandwidth and Colocation Provided by http://www.api-digital.com-- asterisk-biz mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-biz
