Main things to remember for desgingin the wireless solution are coverage and capacity. Challenge for desgin anf tshoot wireless networks is the RF interferance in the form of cochannel interferance. It can cause signal degaration, poor performance, dropped connections. A higher nosie follor by the devices like Bluetooth, Voip phones, Microovens, secrity cameras can cuase it and it creates more re transmissions which might degrade the performance. AP installiation types- Celing , floor, side- SISO- one Tx and One RX- this is leagacy setup in 802.11 a,b,g MIMO-tranmit and receive multipile data streams via multipile antenanas at the same time- provides faster throughtput. MU_MIMIO- differnt users transmit data along separeate streams.
