CellMetric launches 4G LTE eNodeB Test Signal Generator

CellMetric’s Modus 6 LTE base station test signal generator consists of one or more Modus 6 air interface units providing the RF transmission and LTE Composer, a PC based application which generates the protocol and RF transmission scenarios to emulate eNodeB base station transmissions. The LTE Composer application has been developed in close collaboration with Qasara Ltd, ( www.qasara.com ) a specialist LTE technology development company. The combination of the two tools provide a highly flexible, comprehensive and cost effective solution for LTE User Equipment (UE) and handset baseband and RF development and testing.

CellMetric’s LTE tester provides a highly sophisticated RF and protocol sequence generation environment in which LTE RF and baseband chipset companies and cellular handset developers can quickly test their solutions against a repeatable and deterministic test stimulus over the air. This capability includes RF channel emulation allowing the signal generator to generate a RF signal as seen either at the output of the base station transmit antennas or at the input of the user equipment’s receive antennas. Both transmit and receive Multiple-input Multiple-output (MIMO) antenna configurations can be emulated by using two synchronised Modus 6 air interfaces. Modus 6 supports LTE RF channel bandwidths of 1.4, 3, 5 and 10 MHz in the band 824 MHz to 2155 MHz that is FDD bands I, II, III, IV, V, VI, VIII, IX and X and TDD bands a, b and c.
