0 Introduction Introduction 1.4. Purpose Cellular telephone systems transmit signals in two directions between base transceiver station (BTS) and mobile stations (MS) within the signal coverage area. If weak signal transmissions occur within the coverage area because of indoor applications, topological conditions or distance from the transmitter, extension of the transmission range can be achieved by means of an optical distribution system.
0 Introduction The ION-U L 7/8/85/17/19 is capable of supporting both SISO and MIMO. RF signals are transported to the remote units via single mode fiber at 1310 nm. MIMO is achieved with the use of 4 fibers and the pairing of two interlinking RUs. The system includes an Automatic Gain Control (AGC) that avoids field adjustments and reduces design, installation, and optimization time. The ION is easily set-up and supervised via a graphical user interface (GUI).
