Question

4. Suppose an 802.11b station is configured to always reserve the channel with the RTS/CTS sequence. Suppose this station suddenly wants to transmit 1,000 bytes

Answer 1

The time required to transmit the frame and receive the acknowledgment DIFS + 3SIFS +820μsec

What is Bytes?

• Digital information is stored in units called bytes, which typically have eight bits.
• The byte is the lowest addressable unit of memory in various computer architectures because it was historically the amount of bits needed to encode a single character of text in a computer.
• Network protocol specifications such as The Internet Protocol (RFC 791) refer to an 8-bit byte as an octet to distinguish them from the ordinary 8-bit definition.
• Depending on the bit endianness, an octet's bits are typically counted from 0 to 7 or 7 to 0, respectively. Since the initial bit is a zero, the eighth bit is a seven.

I hope you are trying to ask the question below:

Question:

Suppose an 802.11 b station is configured to always reserve the channel with the RTS/CTS sequence.

Suppose this station suddenly wants to transmit 1,000 bytes of data, and all other stations are idle at this time.

As a function of SIFS and DIFS, and ignoring propagation delay and assuming no bit errors, calculate the time required to transmit the frame and receive the acknowledgment.
