Do we like the SXT’s? Yeah, very much.
But in the old days we could use two power inputs (for failover use when two power sources are used, one on the powerplug, one on the PoE-in port) on most CPE setups.
Now we can’t anymore. And about 50% of failures are power failures of power adapters.
More advantages of 2 PoE-In port CPE units: Yes!
One antenna per two (attached) houses. Now we always need a switch or extra router to place at one of the two clients and than we have the issue who is responcible for the power supply?
By having a dual power input with fail over (either two Poe-in ports or one poe-in with one normal port and the use of a power-take-off lead) you can hook-up two clients on one antenna and that antenna has than even better power redundancy for both of the clients than you would have with two antennas, one for each.
This would not only bring the cost per client down by at least 50%, it give better powerbackup and, of the highest importancy; reduce the amount of antenna’s that have to be associated to that one crowded AP!
(The AP is better in handling 6Mb of traffic towards 25 antenna’s than 3Mb towards 50… So, you can either use more antennas per AP, or grant better speed/latency to your AP associated clients.)
Remark; Ok, three port would be an idea as well. But I think we can settle for 2 port units…
