LTE air interface characteristics & LTE Channel Function

The air interface is the radio-based communication link between the mobile station and the active base station. LTE air interface supports high data rates. LTE uses Orthogonal Frequency Division Multiple Access (OFDMA) for downlink transmission to achieve high peak data rates in high spectrum bandwidth. LTE uses Single Carrier Frequency Division Multiple Access (SC-FDMA) for … Read more

How to consider Interference Protection and Isolation Requirement in LTE Plan

Similar to any radio network, standard isolation would be required if equipment from different vendors are to be combined. Which including guard band, filtering as well as vertical/horizontal separation. In addition, indoor DAS (distributed antenna system) may contribute to interference problem particularly on the uplink due to PIM related inter-modulation, over drive of input RF … Read more
