Hello, I jus came accross cisco aironet 1600 series AP and in its tech spec saw ' 3 x 3 multiple-input multiple-output (MIMO) with two spatial streams'.
3*3 means there are three receiving antenna's and 3 transmitting antenna's right? so how can it only form two spatial stream???? please help it is confusing me!!
which is the equivalent Aruba product here? will it be 105 which is 2*2 or 115 which is 3*3 or we should place external antenna based models(e.g ap104) as this cisco product has external antenna?
thanks for your reply...this cisco ap can form 2 spatial strems, but however are 3*3 mimo....i think it is somekind of fancy thing cisco is advertising but in reality it is 2*2.....still i m not sure what it is...
To OP, you can have three available antennas for Rx/Tx but only two are actually used. So the net:net is that when compared to a 3x3:3stream AP, a 3x3:2stream can use all three atnennas to pick the best two, but only use two for Tx/Rx. it will then have 1.5dB less for MRC, TxBF, etc.
