Teletraffic models and planning in wireless IP networks

We discuss teletraffic issues on transmitting IP traffic over a wireless connection. Due to the different characteristics of the transmission over wireless and wired networks concerning error probabilities it is necessary to consider additional measures to mitigate frame errors either by modifying the transport control protocol (TCP) or introducing an error correcting radio link layer (RLL). We analyze a radio link protocol operating with a selective repeat automatic repeat request (SR-ARQ) and describe how different types of users operate with different activity factors and their impact on the system's capacity.
