How to choose a wireless AP?
What problems should be paid attention to when choosing Aruba wireless AP? With the rapid development of the Internet, people's demand for wireless AP is getting higher and higher. To build a wireless network, a wireless AP is essential and attracts everyone's attention. So how should wireless AP equipment be chosen?
Wireless AP is the abbreviation of Access Point, translated as "wireless access node". It mainly provides wireless workstations with access to wired LAN and wireless workstations from wired LAN. communication.
Plainly speaking, a wireless AP is a communication bridge between a wireless network and a wired network. Since the coverage of the wireless AP is a circular area that spreads outward, the wireless AP should be placed in the center of the wireless network as much as possible, and the straight-line distance between each wireless client and the wireless AP should not exceed 30-40 meters. To avoid communication failure due to excessive communication signal attenuation.
In a wireless network, an AP is equivalent to a wired network hub, which can connect various wireless clients. The network card used by the wireless client is a wireless network card, and the transmission medium is air. It only connects the wireless clients, but Internet sharing cannot be done through it. How to use the network wireless ap?
The deployment of wireless APs is different in different environments, and the deployment methods of wireless APs are different in various scenarios such as hotels, squares, and office areas.
1. What are the main factors for choosing a wireless AP?
Five factors are mainly considered: environmental characteristics, installation method, power supply method, coverage area, and machine capacity.
(1) Environmental characteristics: whether the AP is installed outdoors or indoors, and whether the terminal distribution is sparse (such as warehouses) or high-density wireless access (such as conference rooms, restaurants, etc.).
(2) Installation method: Commonly used are ceiling, panel, etc.
(3) Power supply mode: standard PoE (802.3af or 802.3at), Passive PoE or DC (direct current power supply).
(4) Coverage: single room, multiple rooms, area coverage, fixed-point coverage, etc.
(5) Capacity: A single AP can access 10, 20, 30 or 50 terminals.
2. Different types of regions should choose different product types:
(1) Ordinary ceiling-mounted wireless APs are used in general areas, which can achieve a wide range of signal coverage, and small signal blind spots are allowed.
(2) Panel-type wireless APs are often used when accurate and efficient coverage is required, which can guarantee the best wireless coverage effect.
(3) Ceiling-mounted dual-band wireless APs that support high-density access are generally used in densely populated areas to meet the needs of simultaneous multi-person access.
3. How much area is suitable for the wireless AP to cover?
The coverage of the wireless AP has a great relationship with the installation location and the actual environment. The reference information is as follows:
(1) Ceiling-mounted wireless AP: Covers 6 surrounding rooms/dormitories, or a radius of about 12 meters, suitable for installation in an environment with a relatively open environment and a floor height of not less than 3 meters. Due to the characteristics of the installation method, it is easy to produce wireless blind spots.
(2) Panel-type wireless AP: Covering the surrounding 2 rooms/dormitories, 1-2 walls, the wireless coverage effect is better.
