Our life and work have been greatly changed by the wireless technology like WiFi. Our house, office and public places are usually available for WiFi which can be provided by many devices. However, in most public places, WiFi is provided to end users via wireless access point (WAP). Especially for enterprise network, wireless access point is the necessary part of an efficient, complete and flexible data communication network.
Wireless access point is a device used to convert the data from wired Ethernet into wireless signal, letting the devices like computer, tablet and cellphone be connected to the Internet or a network. WAPs are usually deployed in office environment and some public places like train station and hospital. The deployment of WAP allows end users in public places get wireless access to the Internet at any place of a certain area.
The capacity of a wireless access point is related to many factors. Before buy wireless access point, several key factors should be considered.
The price of a wireless access point is closely related to the speed that it can support. It increases with the increasing of the speed. The most commonly used wireless access point usually support speed of 300Mbps, 1200Mbps, 1750Mbps or higher.
The wireless access point is an active device which means it requires electrical power during working. However, wireless access point is usually deployed on the wall or ceiling where power outlet is usually lack of. Thus. PoE (Power over Ethernet) technology is being used in wireless access point. Ethernet network cable can be used for power supply and data communication for wireless access point with PoE. Now, many wireless access point can support both PoE and power cord for power supply.
Terminals and Coverage
As above mentioned, wireless access point can only cover a certain area as the wireless signal can be easily weakened by a lot of things. The transmission distance of the wireless access point is limited. The coverage of a wireless access point is really important. The following listed several commonly used wireless access point with PoE for your reference about the terminals and coverage.
Single-Band or Dual-Band
The wireless signal has radio frequency bands. 2.4GHz and 5GHz are the two bands for WiFi. Generally, the 2.4GHz can provide longer range, while 5Ghz can provide more channels and has less interference. Some wireless access point can support only one of the two bands, and some can support both the 2.4Ghz band and 5GHz band. They are usually called single-band WAP and dual-band WAP.
Wireless access point as mentioned is usually designed into wall/ceiling mounted boxes. The installation steps of these boxes provided by different vendors are usually similar. Here takes the example of a ceiling mounted wireless access point to illustrate the installation (shown in the following picture).
To take a wireless access point into work, a length of Ethernet cable is usually used to connect the wireless access point to a PoE switch as shown in the following picture. However, if you are using a non-PoE WAP, an additional power cords and adapter is required to connect the power outlet to provide low voltage for the wireless access point.
Wireless access point is an ideal WiFi solution for public places like office, hospital, train station, etc. During the selection of a wireless access point, the speed, power supply, coverage and radio frequency band should be considered.
