Internet surfing and online information exchange through e-mails have necessitated users to have easier and more convenient access. While broadbands allow for such access through a landline connection or through the use of USBs, these still pose an inconvenience and limited accessibility. The wireless network connection to the Internet, the IEEE 802.11 technology or commonly referred to as WiFi, is a preferred alternative. However, despite the advantages that WiFi offers, there are WiFi interferences that result in less than efficient connections.
Possible causes of WiFi interference
Many wireless technologies, other wireless local area networks (LANs), and electric devices cause WiFi interference. As WiFi depends on radio frequency (RF), interfering signals from other RF sources result in poor connection. Each 802.11 station only transmits packets when there is no other station transmitting. If another station happens to be sending a packet, the other stations will wait until the medium is free. In certain cases, even with RF interference, a WiFi station will automatically switch to a lower data rate, resulting in slower wireless applications. Devices that cause WiFi interference are portable phones, cordless phones, microwave ovens, Bluetooth devices (e.g., laptops and PDAs), wireless video cameras, outdoor microwave links, wireless game controllers, and fluorescent lights.
Dealing with WiFi interference issues
In order to minimize WiFi interferences, WiFi providers should undertake certain steps. Before installing a WiFi connection, know the other RF sources in the vicinity. Ensure that the area has strong wireless LAN signals. Tune access points to channels that avoid the frequencies of interfering signals. Or, deploy a WiFi connection along the 5 gigahertz band. Whenever possible, disallow or minimize the use of Bluetooth-enabled devices or microwave ovens within the area.
A WiFi user should be ready to accept that WiFi interferences can be experienced. However, the benefits of WiFi far outweighs the problems that come with it.
