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.
Speed Ratings. Wireless routers typically advertise their speed in megabits per second (Mbps). The first consumer Wi-Fi models offered 11 Mbps, followed by mid-range 802.11g routers at 54 Mbps, 802.11n routers anywhere from 150 Mbps to 600 Mbps, with 802.11ac routers now offering above 1 Gbps. You may be tempted to only look at those routers with the highest Mbps rating.
