Assessment of GSM-link quality dependence on radio dispersion in rural environments

The results of two separate measurement setups to investigate GSM-link quality dependence on radio dispersion in rural Faroese and Danish environments, a repetitive GSM-data burst sequence system, and a correlation sounder are presented. Both operated in the 900 MHz band. It is shown that the GSM system performance seems to be sensitive to Q16 both below and above the specified value of 9 dB, while the delay spread is of minor influence when Q16 is infinite. The burst error distribution seems quite unsensitive to interleaving for BER <10% and vehicle speeds of 40 km/h.<
