How wide is/are the existing 2.4/5 GHz ISM band(s)?
- ChuckMcM 7y ago40Mhz and 20Mhz
- herpderperator 7y agoand 80 MHz and 160 MHz
- dboreham 7y agoWrong. 20MHz is the channel width (bonded together to make 40, 80 and 160MHz aggregate channels). There are three non-overlapping channels in the 2.4GHz band (so 60) and "many" in the existing 5GHz allocation. In some countries there's an extra usable channel in 2.4GHz. Once you bloat up to 160MHz (which is needed to achieve the highest marketing speeds) it is hard to find clear gaps in today's 5GHz because it isn't contiguous.
- tradertef 7y ago5 GHz is not ISM, but UNII in USA. Similar. 2.4 GHz has 83 MHz spectrum 5 GHz has 580 MHz spectrum but part of it is shared with radars. 6 GHz is 1200 MHz, double of what we have today!!
