Am I on the right track

Hi guys,

After testing out Routeros 2.9.40 and beta 3v6. I think I am now ready to deploy my first POP.

Hardware:

2 gb ddr400
5x RB11
7x Sr5
Pentium 4 3.2
512 DOM L5 Routeros

3x 17dBi 90deg WIDE BAND Sector Antenna, 5.4-5.8GHz or
2x 16dBi 120deg WIDE BAND Sector Antenna
2x Dual polarity dish http://www.pacwireless.com/products/DA5x-27DP.shtml
RB532A to be used as backhaul to ISP 10Mbps

CPE
RB133c
RB52
Arc Wireless 4.9-5.9 GHz 23 dBi Panel Antenna with Integrated Electronics Enclosure

What I am planning to accomplish here is to provide is provide both voice and data to customer. Bandwidth 1-6Mbps per customer.

I have been ardently reading through the forums to get ideas from others deployment. I will be using 5.6 GHZ between clients up to 5 miles away and the base station and 5.8 Ghz for backhaul 2 miles link. In the future I will be increasing the number of POP throughout the city to provide a more robust network. The altitude of my POP is at 1500ft with clear line of sight to about 12 miles (this line of site is every WISP dream). Google Earth coordinates 18 03’49.79" N and 76 46’28.44" W. The main POP I will sectorized as much as possible as not to allow too many users on one radio. Will be using PPPoE for clients connectivity and bandwidth queueing at cpe end. Userman loaded on a separate machine for AAA and connected to th. Why am I using 5Ghz frequency band? This is to prevent as much interference from hotspot shops within clients range as they are using 2.4Ghz.

Is this setup a good one or am I overlooking something? Is linking a cpe 5 miles away to much for 5.6 Ghz, what range should I look for? Is having 5 ap cards in one box too many and as these will be sr5 cards how much interference between each other should I expect?

Any input will be greatly appreciated.

thanks
