Experimental results from the UK test-bed on the DCS1800 radio channel

A collaborative LINK research project has been in progress since early 1990 to develop the DCS1800 test bed and use this equipment to investigate the radio path performance of a GSM-type TDMA system at 1.8 GHz. Prior to this programme, Orbitel possessed a 900 MHz digital cellular radio test-bed to verify the operation of the GSM system to be implemented throughout Europe. This test-bed was upgraded to operate in the 1.8 GHz band by the use of two low noise up/down converter units designed and built at Bradford University to Orbitel's specification. The authors detail results from initial field trials carried out in areas around Basingstoke and Bradford and compare them to measured results using a fading simulator with the GSM path profiles defined by ETSI.<
