Over the time while IEEE 802.11 was developed, rate adaption algorithms had their own development stage. Most of rate adaption algorithms are not standardized and there are no rules on how one should operate. Therefore, this part of IEEE 802.11 is handled entirely by wireless vendors. Although, while IEEE 802.11 moved forward and introduced several performance increases with Quality of Service introduction,...
The usage of IEEE 802.11 wireless equipment has been growing in recent years. Nevertheless, the spectrum which is used by such equipment is already overcrowded and due to this, the performance of wireless devices is decreasing. Recently, IEEE 802.11 was updated with the latest IEEE 802.11ac version. IEEE 802.11ac provides higher modulation capabilities and more robustness against interference. With...
IEEE 802.11 is one of the most common technologies these days. Due to its simplicity and easy integration in various applications its usage in recent years has grown exponentially [1]. The increasing amount of wireless devices and various applications such as WBAN (Wireless Body Area Networks), WISPs (Wireless internet service provides) have increased the interference in unlicensed band, which reduced...
IEEE 802.11 has become one of the most used wireless access technologies amongst home users and Wireless Internet Service Providers (WISPs). Thanks to flexible use and easy deployment the amount of equipment grew exponentially. However, the growing number of wireless devices both at user premises and in WISPs infrastructure leads to increased interference, which reduces the total effective capacity...
This article describes one of many possible paradigms for future wireless applications. The spectrum in which Wi-Fi operates these days is overcrowded and currently applied rules for Wi-Fi operation are not up-to-date. By adopting a new set of rules for Wi-Fi, it is possible to eliminate some of the currently defined constraints such as Equivalent (Effective) Isotropic Radiated Power limitation (EIRP)...
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. Such rules originate from the rudimentary applications originally envisaged for such spectrum, which don't consider the current technical capabilities of radio devices. This paper introduces the concept...
The use of wireless equipment in the already-overcrowded ISM bands had been further growing in recent years. This increase leads to high interference levels, which causes unstable communication and an average throughput reduction in heavily-used channels. This calls for more robust, interference-aware means of channel-access for Wi-Fi and similar wireless devices in ISM bands. In this paper, we propose...
