HotSpot Idea using Antenna Sector!

Hello,

I was planning to change my network design due to the bad weather as it is really affecting on cables .. always we have to replace cables at our customers side …

we are in the city ..My plan is to broadcast my SSID into whole 2 Kilo Meters with huge building as they re next or so close to each others . I dont want to install on the roof anymore . My signal on that distance is Perfect but we want to add more sectors to cover all buildings , all floors etc

I was thinking to have more than 6 sectors to cover all areas (2km) so customers can install for example DLINK ACCESS POINT 2100 or Mikrotik routerboards to have it inside their houses! .. at the same time I can broadcast using XAGYL 1Watt txpower .

Does that work with us perfect?

My real question is can we broadcast every 100meters or 200 meters using the same SSID! same channel !! .. because im using 2.4 GHZ 108Mbps-Turbo Channel to reach at least 16Mbps data-throughput globally on the whole channel but it doesnt matter about the speed for the end user which means they can have maximum 1 Mbps !

I really need your comments please
Thank you alot & I appreciate your help
