Error updating group for lan to lan connection
In the US, 802.11a and 802.11g devices may be operated without a license, as allowed in Part 15 of the FCC Rules and Regulations.
Some earlier WLAN technologies used lower frequencies, such as the U. Originally described as clause 17 of the 1999 specification, the OFDM waveform at 5.8 GHz is now defined in clause 18 of the 2012 specification, and provides protocols that allow transmission and reception of data at rates of 1.5 to 54 Mbit/s.
It specified two net bit rates of 1 or 2 megabits per second (Mbit/s), plus forward error correction code.
It specified three alternative physical layer technologies: diffuse infrared operating at 1 Mbit/s; frequency-hopping spread spectrum operating at 1 Mbit/s or 2 Mbit/s; and direct-sequence spread spectrum operating at 1 Mbit/s or 2 Mbit/s.
As a result, in the marketplace, each revision tends to become its own standard.
The 802.11 family consists of a series of half-duplex over-the-air modulation techniques that use the same basic protocol.
IEEE 802.11 is a set of media access control (MAC) and physical layer (PHY) specifications for implementing wireless local area network (WLAN) computer communication in the 900 MHz and 2.4, 3.6, 5, and 60 GHz frequency bands.
