Need suggestion on WiFi Network in an Urban area

hi everybody !

I am Litu writing this letter to you from Dhaka, Bangladesh. Actually I’m writing this one to get some vital help from you on establishing a WiFi Network in an Urban area. Following are the details of my proposed Network.

a) The Area:

1.The place is called Uttara Model Town, which is within the capital city Dhaka & is about 2 (Two) Kilometers in Radius.

2.The place is full of densely built houses mostly 6 sroried (About 70 Feet in height) Buildings. The houses are made of Brick in Concrete Structure. Moreover, the houses are very closely built to each other (Approx. 5to7 Feet gap between two houses).

3.Not many trees are there in the area but still the number of trees we have here could be sufficient to cause signal drop.

b) The Plan

1.I’m planning to cover the whole of above mentioned area under WiFi Network with Mikrotik router Board RB333 & XR2 with 120 degree 16dBi Sector Antenna x 2 on each node as AP & 1(One) 5Ghz 12dBi Omni Antenna for Backhaul for WDS Mesh Routing.

2.I would like to offer service to my clients having no outdoor antenna in the client’s premise. Rather they will have 600mW PCI Card with 2dBi SMA Antenna installed in Client’s PC. The option would be an USB WiFi Dongle of 500mW power with integrated SMA Antenna.

3.The total number of Base Stations I’ve planned is 3(Three). I assume that, with the power of the radio & antenna stated above will cover atleast 750 Meters in the environment stated. I also plan to put the antennas at around 100 Feet above the ground.

Please take a close look at the attached picture where I have tried to illustrate what I’ve explained above. Please suggest me the if I’m going the right way. I would deeply aprreciate any further suggestion from you to help me build a robust & smooth WiFi Mesh
Network.

Thank you in advence for your kind cooperation & your earliest attention in this matter. Looking forward to hearing from you soon.

Best Regards,

Litu

I doubt 5ghz will work for this application.

I’d be suprised if you get good results off of 2.4 ghz either. Signals of this frequency just don’t penetrate through brick very well. You might be better off trying an XR9 for the AP and build little indoor client units.

I’ve never had good luck getting indoor coverage. It always seems to work best to get an antenna outside the building and bring it indoors via a cable.
