Abstract
In this paper, we consider a radio infrastructure network (RIN), which consists
of Bluetooth Access Points (APs) to provide services to ad hoc users. The RIN
inherently supports both voice and data connectivity. Since Bluetooth offers
the establishment of Synchronous Circuit-Oriented (SCO) traffic, the concept
under study features a low-cost alternative to indoor cellular base stations.
However, a single AP can serve a maximum of only three SCO channels and may not
be capable of satisfying the voice traffic demands in hot spots. In order to
offer more bandwidth in a location with high voice traffic, two or more APs may
be placed in the same coverage area. Respective AP clusters will be denoted as
Multi APs. Three Multi AP concepts for doing the SCO allocation are presented
and discussed. Our findings show that employing Multi APs significantly reduces
the blocking probability
