Hope every body have good day
i have two cases
Case 1 : I am using AP-375 it covers between 50 to 100 M on open space , I want to provide outdoor coverage for an area larger than what the integrated antenna cover, which antenna can extend that coverage out to 300-400M ?Case 2 : I am using AP-314 With With 4 (AP-ANT-1W 2.4-2.5GHz (4dBi)/4.9-5.875GHz (6dBi) Hi Gain Dual-band Omni-Dir Indoor Antenna) , I have building with the following roughly measurement (Length : 27M . Width : 17M , Ceiling height :3M ) the building wall is cinder block , the ceiling is concrete , i have mounting AP along the walls and the ceiling on the hallway to provide room coverage (as you can see attached real site survey ) , i got bad coverage on the room which located on the back of the AP and the room which is 10 m far from the AP , the questions isQ1. what is the is best way to mount the AP based on the building infrastructure i have provided ?Q2. AP314 is 4x4 MIMO on 5Ghz and 2x2 MIMO on 2.4GHZ is the direction and the angel of the ant will be effecting the coverageQ3. is using an extra antenna instead of the 1W antenna will improve the signal coverage for ex 20 W Ant , if yes can you please recommend
Case 1: You need a second access point. Your clients' adapters would not have the strength to answer reliably to an access point at that distance.
Case 2: If you want coverage in rooms, you pretty much have little alternative but to mount omnidirectional access points in rooms near users. Cinderblock degrades wifi considerably and hallway mounting ends up putting users 2, 3 and possibly 4 walls of cinderblock between users and access points. Hallway mounting also introduces alot of cochannel interference which, in addition to providing poor coverage, provides poor performance.

Thanks for your answer and the helpful link you have provided below
I have totality understand the microcell architecture by adding AP's on the room near users , but i think this scenario is not be suitable for me for many reasons
1- i am not planning to renew my infrastructure and i want to use the the existing ap on the hallway
2- i can't put AP on the user room for many reason
which is mean i want to go ahead with hallway deployment with achieving the best performance , is i am able to do this by dual radio ap for ex ap105 on the both end of the hallway
If you deploy in the hallway, you have to accept (1) poor coverage in rooms (2) cochannel interference by so many access points needed in the hallway to provide adequate coverage in rooms. If you have wired connectivity in your rooms, I would consider putting a wallbox access point, so that you don't have to run any additional cabling: https://www.arubanetworks.com/assets/ds/DS_AP303H.pdf
so using different type of antenna (like 20w ant ) will not help ?
A sector antenna will provide better coverage down the hallway, but it will not give better coverage inside the rooms, if the access point/antenna is mounted outside, unfortunately.
Just to follow up, a sector antenna right outside a room will not provide more coverage than an omnidirectional antenna right outside the room. A sector antenna just focuses the energy in a different direction, but it does not create any more energy than an omnidirectional antenna.
