WLAN Throughput Performance - Research Paper Example   When there are multiple simultaneously active users transmitting data on the WLAN radio channel, the throughput decreases. This is because the users experience a collision. These colliding parties must wait for a defined back off period before retransmitting. This results in loss of air time thus affecting the system’s throughput.†¢ InterferenceRadio based WLAN are unregulated. Other products transmitting energy in the same frequency spectrum results in interference. For instance, microwave ovens can be a source of interference to a WLAN system. Most WLAN manufacturers design their products to account for this interference. Interference mostly arises from other access points (AP) on the same and adjacent radio channels. It can be mutual and harmful. In minimizing interference, different radio channels are used. Frequency hopping and other frequency optimization techniques are developing to help manage interference.†¢ Interoperability of wireless devices  WLAN s ystems from different vendors may not be interoperable. This is because different technologies will not interoperate. For instance, a system based on spread spectrum frequency hopping technology will not communicate with another system based on spread spectrum direct sequence technology. Moreover, systems using direct frequency bands will not interoperate even if they employ the same technology. In addition to that, systems from different vendors may not interoperate even if they both employ the same technology.
