IEEE 802.11g-2003 or 802.11g is an amendment to the IEEE 802.11 specification that operates in the 2.4 GHz microwave band. The standard has extended link rate to up to 54 Mbit/s using the same 20 MHz bandwidth as 802.11b uses to achieve 11 Mbit/s.
As shown in the table below, the wireless 802.11n router modem has the best coverage in terms of distance. However, it doesn’t eliminate blind spots (dead zones) when it comes to internet sharing between 2 different houses.
Wprowadzenie standardu 802.11 g przyczyniło się do znacznego zwiększenia wydajności sieci bezprzewodowych oraz zmniejszenia wymaganego zużycia energii. W porównaniu do 802.11 a poprawił się również maksymalny zasięg – do 50 metrów w budynku oraz 100 metrów na otwartej przestrzeni.
802.11b, 802.11g, and 802.11n-2.4 utilize the 2.400–2.500 GHz spectrum, one of the ISM bands. 802.11a, 802.11n, and 802.11ac use the more heavily regulated 4.915–5.825 GHz band. These are commonly referred to as the "2.4 GHz and 5 GHz bands" in most sales literature.
27 gru 2022 · 802.11g was approved in June 2003. The standard made an attempt to combine the benefits provided by the last two standards – 802.11a & 802.11b. Thus, 802.11g provided the bandwidth of 802.11a (54 Mbps). But it provided a greater range by operating at the same frequency as 802.11b (2.4 GHz).
5 lis 2020 · A general rule of thumb in home networking says that Wi-Fi routers operating on the 2.4 GHz band can reach up to 150 feet indoors and 300 feet outdoors. Older 802.11a routers that ran on 5 GHz bands reached approximately one-third of these distances.
In 2003, the IEEE ratified the 802.11g standard with a maximum theoretical data rate of 54 megabits per second (Mbps) in the 2.4 GHz ISM band. As signal strength weakens due to increased distance, attenuation (signal loss) through obstacles or high noise in the frequency band, the data rate automatically adjusts to lower rates ( 54/48/36/24/12 ...
