- is used to extend the coverage
area of your Wi-Fi network.

2. Network Repeater
-The specific characteristic of
this is that whatever it
receives it transmits to the
other LAN segment. This
does not understand the
frame format and also
physical addresses. In other
words, it is a transparent
device. Therefore, multiple
LANs connected by
repeaters may be
considered as a single LAN.

- is used to amplify
signals to support and
carry long distance calls.
