PU is an exaggerated pronunciation of pew, an interjection that is appropriate when you smell something foul.
Unimpeded Maximum. Currently, routers running the 802.11n standard have the longest range. The unimpeded range, at the same data rates, is roughly double that of the previous 802.11g standard.802.11g was widely regarded as having an effective range between 100 and 150 feet, meaning the 802.11n standard â the latest adopted standard available â covers roughly 200 to 300 feet.he unimpeded range, at the same data rates, is roughly double that of the previous 802.11g standard. 802.11g was widely regarded as having an effective range between 100 and 150 feet, meaning the 802.11n standard â the latest adopted standard available â covers roughly 200 to 300 feet.
The first generation of wireless routers was âb,â followed by âg,â and now ânââthe newest generation. The primary difference among the router standards is speed (more on that in a bit) and range. You wonât find many âbâ routers available anymore (except on eBay, perhaps) because itâs old technology. If youâre currently using âbâ routers on your network, you should consider upgrading. Single band vs. Dual band. Wireless communications operate in two bandsâ2.4GHz and 5GHz. Routers based on 802.11b and 802.11g standardsâand some ânâ routersâuse the 2.4GHz band; however, the 802.11n standard allows wireless devices to use the 5GHz or 2.4GHz band.
