GPRS( 2.5G - GSM evolution)
GPRS -various test modes
􀂋 Test Mode A
ETSI 4.014 test mode commands the mobile into a
transmission mode of a PRBS (Pseudo Random Bit Sequence)
􀃎allow Tx measurements
􀂁 power versus time
􀂁 phase and frequency
􀂁 spectrum (modulation/ switching)
􀂋 Test Mode B
ETSI 4.014 test mode closes the mobile
internal BER loop for GPRS (CS1-4) coded radio blocks
􀃎 allow Tx and Rx measurements:
􀂁BER
􀂁 DBLER
􀂁 + all Tx measurements
described in Mode A.......
