Wireless repeater

As explained in Acing the CCNA Exam: Volume 2 Advanced Networking and Security

A wireless repeater is an access point that receives and retransmits a wireless signal to extend network coverage.

A wireless repeater is an access point configured to extend a wireless network beyond the coverage cell of a main access point. It receives the main AP’s signal and retransmits it into areas the main AP cannot adequately reach, making it useful in large homes and offices. section 18.4.1

Key operational facts:

• A repeater is typically a standalone device extending one AP’s range without additional infrastructure. section 18.4.1
• Retransmitting every packet consumes additional airtime and can significantly reduce wireless LAN throughput. section 18.4.1
• Unlike a mesh AP, a repeater does not form an interconnected network that intelligently selects traffic paths. section 18.4.1

Figure 18.19 AP2, in repeater mode, extends AP1’s cell by repeating (retransmitting) wireless signals it receives.

AP2 receives and retransmits AP1’s wireless signal, extending AP1’s cell into an uncovered area. section 18.4.1

How Acing the CCNA Exam: Volume 2 Advanced Networking and Security covers it

How deep it goes

Defines signal retransmission, standalone topology, mesh contrast, and airtime cost without detailing configuration commands.

Examples

Uses large homes, offices, and an AP2 repeating AP1’s signal as concrete coverage-extension examples.

What it assumes

Assumes a main access point and recognizes wireless coverage cells before introducing repeater operation.

What you can do after

Operate or configure an access point as a repeater and anticipate its throughput penalty.

How it connects

Contrasts wireless repeaters with mesh networks and mesh access points while relying on access points and wireless coverage cells.
