As the frequency of a radio wave increases its data carrying capacity decreases.

A parity check is an example of an error correction code.

If five users are connected to a wireless network that offers a maximum data rate of $54$Mbi$\frac{t}{s}$ and a throughput of $60\%,$ the typical practical data rate available to each user in ideal conditions will be less than $7$Mbi$\frac{t}{s}.$

A wireless access point is an essential component of a Wi$-$Fi ad$-$hoc network.

MIMO and frame aggregation are techniques used in recent Wi$-$Fi standards for increasing capacity.

In Wi$-$Fi networks, the CSMA$/$CA protocol can only be used when RTS and CTS frames form part of the procedure.

The $2\mathrm{.}4$ GHz ISM band runs from $2\mathrm{.}4$ GHz to $2\mathrm{.}4835$ GHz $.$
