CELLMetric Launches RF Channel Fading Options for Modus 6 LTE Composer
Cambridge based 4G cellular & digital broadcast company CELLMetric announces the launch of its new Long Term Evolution (LTE) RF channel fading option for Modus 6 LTE Composer at Telecom 2009 Geneva.
CELLMetric’s LTE Composer 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.
LTE Standard channel fading models included in the Composer option include Extended Pedestrian A Model (EPA), Extended Vehicular A Model (EVA) and Extended Typical Urban Model (ETU).
CELLMetric’s Modus 6 LTE test solution is compliant with Release 8 of the Third Generation Partnership Project standard (3GPP) and supports both Time Domain Duplex (TDD) and Frequency Domain Duplex (FDD) modes.
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 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.
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 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.
The user has complete control over the Physical Downlink Control Channel (PDCCH) with respect to Downlink Control Information (DCI) format types and search space locations. The following physical transport channels, synch signals and reference signal are supported:
o PCFICH Physical Control Format Indicator Channel
o PHICH Physical Hybrid Automatic Repeat Request Indicator Channel
o PDCCH Physical Downlink Control Channel
o PDSCH Physical Downlink Shared Channel
o PBCH Physical Broadcast Channel
o P-SCH Primary Synchronization Channel
o S-SCH Secondary Synchronization Channel
o CRS Cell Specific Reference Symbols
CELLMetric’s LTE base station test signal generator, comprising the LTE Composer Base Station Emulator software and Modus 6 air interface units, is available now from CELLMetric.
