What is the size of data sending frame in macaw?
All data packets are 512 bytes, and the control packets (RTS, CTS, etc.) are 30 bytes.
What is ACK RTS CTS?
RTS/CTS (Request To Send / Clear To Send) is the optional mechanism used by the 802.11 wireless networking protocol to reduce frame collisions introduced by the hidden node problem.
What is hidden and exposed terminal?
Hidden Terminal Problem: In a formal way hidden terminals are nodes in a wireless network that are out of range of other node or a collection of nodes. These nodes are known as hidden terminals. The problem occurs when nodes A and C start to send data packets simultaneously to the access point B.
What is RTS CTS threshold?
CTS/RTS Threshold: CTS means “clear to send” and RTS means “request to send.” These ask devices on a network for permission to send the next data packet. If your Wi-Fi network is stable, set the CTS or RTS Threshold to the maximum allowed — usually 2347.
What is near and far terminal?
The near–far problem or hearability problem is the effect of a strong signal from a near signal source in making it hard for a receiver to hear a weaker signal from a further source due to adjacent-channel interference, co-channel interference, distortion, capture effect, dynamic range limitation, or the like.
How do IEEE 802.11 solve the hidden terminal problem?
IEEE 802.11 uses 802.11 RTS/CTS acknowledgment and handshake packets to partly overcome the hidden node problem. RTS/CTS is not a complete solution and may decrease throughput even further, but adaptive acknowledgements from the base station can help too.
What is preamble mode?
What is Preamble Type. Preamble Type setting means that it adds some additional data header strings to help check the wifi data transmission errors. Short Preamble Type uses shorter data strings that adds less data to transmit the error redundancy check which means that it is much faster.
