Wi-Fi Networks need re-designing for growth.

Telsys.net Editorial Staff, July 20, 2007

Wi-Fi networks are experiencing more congestion as the number of users increase in an already congested and unlicensed spectrum.  With the growing proliferation of Wi-Fi devices the technology is being outpaced by the demand for the spectrum (2.4 GHz) and the different systems (Access Points, Bluetooth, cordless handsets, etc) requiring wireless access.

The Orthognal Frequency Division Multiple Access (OFDMA) air interface technology has to be traded in for a more efficient technology given that the frequency band in not licenced and is woefully congested and wrought with interference. The future of IEEE 802.11 probably lies in CDMA technology for more spectrum efficiency. First question that comes to mind is code management and how this will be handled by the IEEE in the evolution of the 802.11 standard as this path is explored.
