The Lee model for point-to-point mode is a radio propagation model that operates around 900 MHz. Built as two different modes, this model includes an adjustment factor that can be adjusted to make the model more flexible to different regions of propagation.
Many GSM phones support three bands (900/1,800/1,900 MHz or 850/1,800/1,900 MHz) or four bands (850/900/1,800/1,900 MHz), and are usually referred to as tri-band and quad-band phones, or world phones; with such a phone one can travel internationally and use the same handset. This portability is not as extensive with IS-95 phones, however, as IS ...
smaller, simpler, cheaper antennas – 2.4 GHz antennas have less than half the size of comparable-strength 900 MHz antennas and require less lightning protection; availability of proven free software like OpenWrt , DD-WRT , Tomato that works even on old routers ( WRT54G , for instance) and makes modes like WDS , OLSR , etc., available to ...
The high-VHF band (137–174 MHz) and UHF bands (325, 900 MHz) are the most popular aside from the 25–28 MHz "HF CB" bands. There are notable exceptions to this, including the 78 MHz and 245 MHz Thai "CB 78" and "CB 245" VHF-FM bands, the 68–71 MHz Finnish band, the 30–31 MHz Swedish "Hunting Radio" band, and the 43 MHz Italian "VHF CB ...
