TETRA and TETRAPOL are competitors in the market of Professional Mobile Radio (PMR). In a previous study we compared the trunked mobile radio systems TETRA V+D and TETRAPOL by evaluating random access performance. Here we present a comparison of the TETRA and TETRAPOL error correction schemes involved to secure LLC data links. The traffic performance of both systems was compared for ETSI scenario 8. Realistic models for the effects of propagation circumstances and co-channel interference are taken into account. The results of the traffic performance measurements exhibit differences in connection set-up times and transmission delays for data links in TETRA and TETRAPOL systems in favour of the TETRA system and reveal a strong dependency on random access delays.
