A wireless local loop connects customer premise equipment to the local exchange on the public switched telephone network using radio signals. Compared to wireline local loops, wireless local loops are easier to deploy and less costly to maintain. One of the most important considerations in deploying wireless local loops is to determine the best channel allocation algorithm. This paper provides an overview of channel allocation algorithms for wireless local loops, reviews previous related studies, and recommends several future research directions. The algorithm overview and research review can help IS researchers and IS practitioners gain a solid understanding of the channel allocation algorithms. The research directions can serve to guide interested IS researchers in future research.
