What does AP stand for?
AP stands for Access Point. The device that lets wireless clients join a wired network, bridging Wi-Fi to Ethernet. Enterprise APs are often powered over PoE and managed by a controller; a rogue AP is one plugged in without authorization.
An access point is the device that connects wireless clients to a wired network. It has radios on one side and an Ethernet connection on the other and bridges between them: laptops and phones associate with the AP, and their traffic continues onto the switch. An AP announces one or more network names (SSIDs) and enforces the wireless security settings. In a home, the AP is built into the wireless router. In an office, many APs are placed for coverage, powered over their Ethernet cable and often managed together by a controller.
AP in practice: an example
A warehouse has poor Wi-Fi at its far end. A survey shows that the nearest access point is forty metres away, behind steel racking. The fix is another AP mounted in that aisle, cabled to the switch and powered by PoE, with the same SSID and security settings and a channel that does not overlap its neighbour's. Handheld scanners now move between the two without losing the connection.
What AP is confused with
AP vs wireless router: what is the difference?
A wireless router is three devices in one box: a router, a small switch and an access point. A standalone AP only bridges wireless clients onto an existing network and leaves routing, DHCP and NAT to other devices.
AP vs SSID: what is the difference?
The SSID is the network name that clients see. The AP is the hardware that broadcasts it. One AP can offer several SSIDs, and many APs can share one. What SSID stands for
Which exams cover AP?
AP is on the official CompTIA acronym list for two of the four exams covered here.
- Network+ N10-009: 1.0 (Networking Concepts); 4.0 (Network Security).
- A+ 220-1201 and 220-1202: on the acronym list, not tied to one objective.
Each number is a CompTIA exam objective and the name in brackets is its domain. The exam puts the term in a scenario; it does not ask you to recite the expansion.
Check yourself: two practice questions
Written by CertSprint for this page. They are not taken from any exam.
1. An office needs to extend Wi-Fi coverage to a new meeting room. The existing router already handles DHCP and internet access. What should be installed?
- An access point connected to the existing network
- A second DHCP server
- A modem in the meeting room
- A KVM switch
Show the answer
A. An access point connected to the existing network. An AP adds wireless coverage and bridges clients onto the network that already provides addressing and routing. A second DHCP server would cause conflicts.
2. An employee plugs a personal wireless device into an office wall port so that a phone gets a better signal. What is this device called from a security point of view?
- A rogue access point
- An evil twin
- A jump server
- A honeypot
Show the answer
A. A rogue access point. An unauthorized AP attached to the corporate network is a rogue access point: it opens a wireless door into the LAN that nobody manages. An evil twin imitates the name of a legitimate network instead.
