Inter-cell interference in spread-spectrum wireless LANs employing handshake protocols
K.A. Mohamed, László Pap · 2002
We consider the performance of infrastructure wireless LANs based on frequency hopping transmission techniques. The service area is partitioned into overlapping cells, and each cell is assigned a distinct signature sequence that is shared by all terminals inside the cell. A sequence of request-to-send/clear-to-send (RTS/CTS) handshaking procedures precedes the transmission of data frames. Though handshake procedures prevent primary interference, the inter-cell interference lasts and may limit the performance. We develop a unified analysis framework for modeling the inter-cell interference and evaluating the performance of FHSS WLANs in the case of a finite number of users, fixed frame lengths and asynchronous frame transmissions.
