Repeater
Definition:
Electronic device that receives and retransmits it.
Telephone Repeater:
Repeater is inserted at one or more intermediate points in a long telephone line to amplify telephone signal so as to maintain the required current strength.
Carriers two audio signals one going in each direction.
Optical communication Repeater:
Increase range of signals in fiber optic cable.
Consists of photo transistor.
Amplifier.
Electronic filter.
Laser.
Extends coverage of radio signal.
Consists of radio receiver connected to radio transmitter.
It is simple to connect.
Cost is effective.
Ability to strengthen signal.
Disadvantage:
Data gets passed along by a repeater to all other LAN segment of a network regardless of whether it needs to go there or not.
Can't filter network traffic.
Application:
Fire station.
Police station.
Tracking system.

Fiber optic cable:
Carry the light.
Photo Transistor:
Light pulses to electrical signal.
Electronic filter:
Reshapes pulses.
Laser:
Converts electrical signal to light again and sends to fiber.
Radio Repeater:
Consists of radio receiver connected to radio transmitter.
What is the purpose of repeater in networking?
Retimes and regenerates signals to proper amplitude and sends them to other signal.
Repeater station:
Receives a weak signal and retransmit it at a higher level.
How does Repeater operate?
Used to extend coverage area of your wifi network.
Wifi:
Wireless fidelity.
Allows devices to connect to internet.
What is range Extender?
Used to expand the reach of wireless LAN.
LAN:
Local area network.
Connected to a particular area.
What is the best place to put a Wifi extender?
Between your wireless router and your computer, but extender must be within the range of wireless router.
How repeaters are divided for handling data?
Analog repeater.
Digital repeater.
Analog Repeater:
Transmit data in form of an analog signal.
Digital Repeater:
Also known as digipeater.
Transmits data by binary digital signal.
Difference between Repeater and Amplifier?
Repeater is an amplifier amplifying input signal out to other side.
Repeater also amplifies noise as well.
Advantages:
Cost is effective.
Ability to strengthen signal.
Disadvantage:
Data gets passed along by a repeater to all other LAN segment of a network regardless of whether it needs to go there or not.
Can't filter network traffic.
Application:
Fire station.
Police station.
Tracking system.
