Examples: Alvarion carrier WiMax (2.5Ghz), macro and micro uses 48V (maybe you can get it in 24V, the stuff I've seen has all been 48V) With packet optical, if you put a Cyan box in that uses 24V you need separate linecard spares as they aren't compatible with the 48V stuff in core. More microwave backhauls are at 48V. Newer all-outdoor ones are using POE+ / 802.3at which is 48V. Cisco ASR901S pole-mount routers output POE+ so you have one outdoor box to take your fiber and go to microwave to other sites. Most Ethernet switches are AC or -48DC.

The wireline world is 48 volt. So I can see why they would use 24 volts, but 48 is usually only for central office buildings, where there is no radio gear except, perhaps, some old-fashioned fixed microwave. A handful of competitive players are doing microwave collocation in COs, but given the cost, a power converter would be the least of their worries. > > > ----- Mike Hammett Intelligent Computing Solutions > http://www.ics-il.com > > ----- Original Message ----- From: "Robert" > <nos...@avantwireless.com<mailto:nos...@avantwireless.com>> To: "paolo > difrancesco" > <paolo.difrance...@level7.it<mailto:paolo.difrance...@level7.it>>, "WISPA > General List" > <wireless@wispa.org<mailto:wireless@wispa.org>> Sent: Saturday, April 6, 2013 > 11:18:33 AM > Subject: Re: [WISPA] Ubiquiti Rocket Titanium > > Exactly...
