Re: [WISPA] Cat5E
There are a handful of listings on E-Bay. Just do a search for aerial cat5. http://cgi.ebay.com/250-CAT-5E-OUTDOOR-AERIAL-SELF-SUPPORTING-W-MESSENGER-/360248674569?pt=LH_DefaultDomain_0&hash=item53e07e8909 On 4/10/2011 5:05 PM, Blair Davis wrote: > Looking for an aerial, shielded, Cat5E with steel messenger wire > suitable for a 250ft span. > > Anybody got or seen such a thing?

For a growing-up network, I think two half-duplex could be used for better performance. For instance, two OSPF links with unequal inverted costs, so each one will normally have unidiretional traffic, fall-back to bidirectional if one of the links fail. Rubens WISPA Wants You!

Re: [WISPA] RED queues out, PCQ queues in - anyone else doing this?
Rubens, Thanks for the reply! I'm using a 5GHz AirMax back haul (PtMP) to two 2.4GHz APs (All UBNT gear). The 5GHz back haul has never broken a sweat. Our "upstream" is a 1M/256K high latency connection so there just isn't that much data to move. You got me thinking about the ack packets. Besides possibly a queue type, what do you think about prioritizing them high? Thanks!
