Backhaul to AP to multiple Ap - License Limitations??

RouterOS Wireless Networking
1

I want to backhaul using RB532 and Sr5 to a site, lets call this MainSITE and SiteA.
From SiteA I want to broadcast 900Mhz for clients. From SiteA I want to Backhaul to SiteB using sr5 again. At site B I want to broadcast 900Mhz.

Again from SiteA I want to Backhaul using Sr5 to SiteC and broadcast at 900Mhz.

Antenna config for Backhaul = Main Site to SiteA - 3ft Parabolic w/radome (Andrews or simular)
Antenna config for Backhauls = SiteA to SiteB and SiteA to SiteC Sector to Grid
Antenna config for 900Mhz SiteA, SiteB, SiteC = Sector panel to CPE yagi

RB532 w License level 4 from main site - would total # of connected users = max of 200?

From Site A can I locate 2 SR5 cards on the same enclosure for my backhauls with limited or no interferance? (900Mhz SR9 will be on a seperate dedicated 532 Board)

Secondly I am planning on using POE since tower access is not a problem. Is there a max distance on POE? When should one use a power supply rather than POE?

Any suggestions, thoughts, wisdom is very appreciated!

  1. Different license levels do not set any limitation to wireless clients number,
    http://www.mikrotik.com/software.php
    HotSpot provides 200 clients, etc.
    Most likely you will meet ‘standard’ limitations to distribute available wireless bandwidth, imagine 200 users will share one AP connection.

  2. As far as I know PoE cable limit is 100 m.

In most cases PoE cable length will be restricted by maximum Ethernet cable length. In particular this will apply to Mikrotik due to its wide power span.
However, several high-power card might cause too high drop or even temperature rise?
