transmit on orthogonal channels). There are different ways to achieve this separation[3], and two such techniques are discussed here: time division multiplexing (TDM) and binary phase modulation (BPM). These techniques are described as follows, in the context of frequency-modulated continuous-wave
Features include Orthogonal frequency-division multiple access (OFDMA), bi-directional multi-user MIMO and cellular optimization. With up to 2 spatial streams (2SS) and 80MHz channel bandwidth (HE80), the 500 Series provides groundbreaking wireless capabilities for budget-conscious deployments.
