Bit Error Rate Testing

(Or Frame Error Rate Testing)

Q Remove RF Channel from Service and Place in Test Mode

– May be problematic for busy, operational systems

– Need to verify consistent interpretation of the test bit sequence and value

of status bits to avoid baseline errors

Q Digital analyzer or Instrumented Radio Used for Drive Test

– Consider any differences between analyzer or instrumented radios and

the radios which will be used

Q Collect Data

– Configure for sufficient settling time prior to each measurement to

ensure valid BER tests

– Traditional sampling rates (> 40 wavelengths) for measurements in fading

environments still apply

– At normal speeds, the above sampling period will collect sufficient bit

samples to be statistically valid

Q Analyze Data

– Use processes recommended in TSB-88 to segment and analyze test data
