802.11 originally started around 1985 when the US FCC released the license for the use of the ISM band. This had a great impact on the development of industrial, scientific, and medical radio bands technology using radio frequency and developing other applications apart from communication purposes and systems. With the first 802.11 being capable of processing 2 Mb at maximum bandwidth, many applications were too slow for productivity.
Fortunately, the IEEE were finally able to establish a new standard marking the 802.11a and 802.11b making wireless communication up to par with the Ethernet standard at the very least. When routers and other devices were developed following the 802.11b standard, radio signaling frequency was still unregulated. What this meant was that anything that operated in the 2.4 GHz frequency, such as a microwave or wireless telephone, could cause interference...
