Wireless Access Point
What Is An Access Point?
An wireless access point is a device that provides access to a WLAN ( Wireless Local Area Network). Access points are often used in large, heavily frequented offices, while WLAN routers are more likely to be used in smaller offices or in your own four walls. The device supplies a certain area with WiFi signals and is connected to a wired router, switch or hub via an Ethernet cable.
How Does An Access Point Work?
An access point (also called AP or WAP for short ) receives data over a wired Ethernet. Converts it to 2.4 GHz or 5 GHz signals using the IEEE 802.11 protocol. In most countries there is only a limited number of frequencies available for APs. Therefore neighboring APs use different frequencies (channels) to communicate with the clients. This prevents interference between two wireless systems.
An AP sends and receives wireless traffic from nearby client computers. In contrast to a wireless router, an access point has no firewall functions. And cannot protect a local network from threats from the Internet.
The area that an AP can cover depends on many variables. Even if placing a device optimally, the radio signals can be disturbed by metal supports, mirrors or other devices.
Wireless communication is subject to special security aspects. That is why all APs have integrated data encryption . If using a sufficiently strong password, wireless networks becomes secure.
Users Can Move Freely
If an access point is not sufficient to supply an area, the range of a WLAN can be increased using a range extender . A range extender increases the range, but not the available bandwidth. Therefore, limited number of computers connected to a range extender.
By installing an AP in a large office, users can move freely throughout the room or building without a network outage. In this case, users can seamlessly pass from one access point to another without breaking the connection.

What Are The Advantages Of An Access Point?
When employees and guests connect their desktops, laptops, tablets or mobile phones to a wireless network, a high number of accesses can occur very quickly. Business access points can support up to 255 connections at the same time without the user noticing any restrictions. However, this operating state is only achieved under optimal conditions.
Other benefits include:
- Optional encryption methods such as WPA2 protect wireless communication against data spies.
- We can install An AP where an operated wireless network is present. Several of these devices can connect to an intranet .
- An access point enables guest access to be set up without restricting network security.
- The so-called clustering , an administrator can configure multiple access points simultaneously.
Wifi Access Point
What Is A Wifi Access Point?
The best known wireless access points are those in the context of the 802 series of wireless standards, commonly known as WiFi access points. While there are other wireless standards, most of the time the terms WiFi access point and AP are synonymous .
Most WiFi access points closely resemble routers. In fact, modern routers typically function as access points.
The term wireless access point with the term wireless coverage area is confusing sometime.
A wireless access point covers an area with a WiFi signal, while the area where one can connect to the Internet by air is called a wireless coverage area or HotSpot.
Problems With Wifi Hotspots In Companies
Most companies manage their own WiFi access points, but not many know how to achieve the best signal strength and the best possible download and upload speeds.
It is very likely that you have heard that the WiFi signal has a limited range and is affected by various obstacles, such as walls, and interference, caused by the surrounding WiFi network.
In some cases, you may discover that your WiFi hotspot is not strong enough to cover all areas of your business, no matter where you place it. What is the solution? Buy a new access point or install WiFi repeaters.
WiFi amplifiers, on the other hand, can quickly expand the reach of any wireless access point, but create an additional network that doesn’t benefit you unless you manually switch to it.
Why Access Points Are A Better Option For Companies
Although network repeaters are extremely useful for home WiFi networks. They are not efficient enough for the modern professional networks that today’s businesses demand.
Although network repeaters increase the coverage of a WiFi router, they do not increase the available bandwidth and depending on the number of devices connected simultaneously, a WIFi repeater can even reduce the overall network performance.
WiFi access points, on the other hand, can operate many simultaneous connections per device.
By installing WiFi access points throughout the company. Users can move freely in all facilities, without suffering interruptions in the service.

Advantages Of Installing Wifi Access Points
If both your employees and customers connect to the WiFi network using their computers, laptops, mobiles and tablets, the maximum number of connected devices would be filled quickly.
The WiFi professional solutions provide the ability to handle several concurrent connections offering the freedom to scale the number of devices that the network can support. However, this is only one of the advantages of using these WiFi access points, also:
- > Professional WiFi access points can be installed in any location where you can place an Ethernet cable.
- > The most modern models of WiFi access points are also compatible with the Power over Ethernet Plus (PoE +) function, a combo between an Ethernet cable and a power cable, so it is not necessary to install additional electrical wiring or a plug.
- > They include Captive Portal and the Access Control List (ALC), so you can limit access to guest users without compromising network security and managing accounts within your WiFi network.
- > Some access points include the clustering function, which offers a unique point from which the IT administrator can view, install, configure and protect the WiFi network as a single entity instead of as multiple access point configurations.
