In the 802.11g standards battle, PBCC eventually lost ground to OFDM, or Orthogonal Frequency Division Multiplexing, as the modem of choice. The equipment costs the same as other Wi-Fi networks but downloads files at double the rate.
The opposing technology approaches are orthogonal frequency division multiplexing (OFDM) and direct sequence (DS)-UWB. This increases the signal's range by reducing interference. The former method, backed by Intel, is more complex: it chops up the...
In the not too distant future, you will be able to add 3G Long Term Evolution (LTE), mobile WiMax, multiple in multiple out (MiMo) and orthogonal frequency division multiplexing (OFDM) to the mix. G-HSPA offers an alternative, back-up connection...
They radiate energy from high-speed data signals which becomes a source of interference for wireless services including broadcast radio as well as emergency, maritime, aeronautical, military and navigation services.
While 802.11a equipment is considered more secure and operates in different radio frequency than Wi-Fi to reduce interference, it is not compatible with Wi-Fi or upcoming 802.11g products. The 802.11g network is much faster, although it operates in...
You need to start with projects that are robust enough to resist the interference and abuse from politicians, technologists and civil-servants without jamming. This month I was asked to visit a Middle Eastern country and evaluate their progress...
