Advantages of Repeaters :

  1. Cost –
    The cost of repeaters is less than compared to the other network. They’re going to be purchased at minimal expense. However, that does not deny the actual fact that it requires other kinds of expenses. One such is that the utilization of electricity.


  2. Network Performance –
    Repeaters don’t always depend on a processing overhead. So that’s why the performance of the system is also affected.


  3. Enhance Signal –
    Whenever a computer and a router is placed far apart, it’ll end in weak signals. Repeater has the potential to strengthen signals so as that they are often retransmitted much stronger with better performance.


  4. Network Extend –
    Other than enhancing signals, repeaters has the facility to extend the length of the transmission. It means it can extend the whole distance covered by the network albeit it is a wired or a wireless medium.


  5. Physical Barriers –
    Physical hurdles may lead to the weakening the overall signals of wireless connectivity. Employing a wireless repeater, these impacts are often reduced so as that there will be an assurance that signals are getting to be delivered to the computers.


  6. Media Support –
    In repeaters, networks are often connected for reception and transmission using various physical media. The foremost popular kind of media is that the cables.

Disadvantages of Repeaters :

  1. Network Traffic –
    Repeaters are unable to segment network traffic. Hence, they lack the potential to reduce congestion also as network traffic.


  2. Specification – 
    Repeaters are also unable to connect networks of varied architectures. For this purpose, either a gateway or a router is required.
