Which of these is not a feature of WLAN hotspots?

It requires no registration
It requires no password
It is usually free
It does not require mobile station

Correct Answer

A. It does not require mobile station

Explanation

WLAN hotspots are wireless networks that allow devices to connect to the internet. They typically require registration, as users need to provide their personal information to gain access. They also usually require a password for security purposes. Additionally, while many WLAN hotspots are free, some may require payment for usage. However, one feature that is not typically associated with WLAN hotspots is that they do not require a mobile station. A mobile station refers to a device, such as a smartphone or tablet, that connects to the hotspot. Therefore, the correct answer is "It does not require mobile station."

Two
Three
Four
Five

Correct Answer

A. Two

Explanation

IEEE 802.11 has two basic modes of operation: infrastructure mode and ad hoc mode.
