An experimental study of inter-cell interference effects on system performance in unplanned wireless LAN deployments

Mesut Ali Ergin, Kishore Ramachandran, Marco Gruteser
2008 Computer Networks  
Environments in which these WLANs are deployed, have many nearby access points and stations on the same channel, either due to lack of coordination or insufficient available channels.  ...  However, we find that with a typical TCP-dominant workload, cumulative system throughput is characterized by the number of actively interfering access points rather than the number of clients.  ...  Acknowledgement We thank Dipankar Raychaudhuri and Ivan Seskar of WINLAB, Rutgers University for their valuable comments on this study.  ...

2014 2014 IEEE International Symposium on Dynamic Spectrum Access Networks (DYSPAN)  
Access to unlicensed spectrum has thus far been based on simplistic rules, such as a transmission power limitation, requirement for tolerance of interference, and a relaxed out-of-band transmission mask  ...  Moreover, constraints such as on transmission power can be relaxed under the proposed scheme, and the stability in performance of unlicensed spectrum can be improved.  ...  The work of Dr. Oliver Holland was additionally supported by the EU FP7 project ICT-SOLDER.  ...

A case for adapting channel width in wireless networks

Ranveer Chandra, Ratul Mahajan, Thomas Moscibroda, Ramya Raghavendra, Paramvir Bahl
2008 Computer communication review  
Through detailed measurements in controlled and live environments, and using only commodity 802.11 hardware, we first quantify the impact of channel width on throughput, range, and power consumption.  ...  For instance, when the throughput required is low, moving to a narrower channel increases range and reduces power consumption; in fixed-width systems, these two quantities are always in conflict.  ...  Improving fairness and balancing load in WLANs In today's 802.11g based WLANs, each AP is assigned a fixed width 20 MHz channel, and if possible, neighboring APs are placed on orthogonal frequencies.  ...
