What are the wireless LAN protocols?
Different Wi-Fi Protocols and Data Rates
| Protocol | Frequency | Maximum data rate (theoretical) |
|---|---|---|
| 802.11n | 2.4 or 5 GHz | 450 Mbps3 |
| 802.11g | 2.4 GHz | 54 Mbps |
| 802.11a | 5 GHz | 54 Mbps |
| 802.11b | 2.4 GHz | 11 Mbps |
What type of protocol is 802.11 b considered?
Specifications for Wireless Local Area Networks & Protocols that will be supported on the network. (Protocols are also referred to as 802.11.)…Standard Protocols / 802.11.
| Wi-Fi Protocols | Release Date | Maximum Data Rate (Mbps) |
|---|---|---|
| 802.11b | Sep 1999 | 11 |
| 802.11a | Sep 1999 | 54 |
| 802.11g | Jun 2003 | 54 |
| 802.11n | Oct 2009 | 600 |
Why is the physical layer in IEEE 802.11 subdivided?
IEEE 802.11 standard, popularly known as WiFi, lays down the architecture and specifications of wireless LANs (WLANs). Users connected by WLANs can move around within the area of network coverage. …
What is the difference between 802.11 a and 802.11 b?
Due to its higher cost, 802.11a is usually found on business networks whereas 802.11b better serves the home market. 802.11a supports bandwidth up to 54 Mbps and signals in a regulated frequency spectrum around 5 GHz. This higher frequency compared to 802.11b shortens the range of 802.11a networks.
Is Wi-Fi physical layer?
All Wireless LANs operate on the Physical and Data Link layers, layers 1 and 2. All Wi-Fi systems use these layers to format data and control the data to conform with 802.11 standards. Medium arbitration-controlling when the AP can access the medium and transmit or receive data-is done at these two layers.
Which modulation techniques are used in wireless LANs?
Wireless LANs use digital modulation to transmit digital signals. An RF signal can be modulated by manipulating the frequency, phase, or amplitude. Amplitude modulation is not sufficient alone for wireless LAN technologies since the amplitude is often affected by interference.
