How to select the most suitable Wireless AP and the most suitable Wireless AP

With the popularization of networks and the wide application of smartphones, Wireless AP is increasingly used in various occasions. However, many people may not understand the choice of Wireless AP. On the basis of summing up your experience, I will share some comments on the Internet with you the precautions for choosing Wireless AP for your reference.

1. Notes

When selecting an AP for wireless coverage, the following aspects should be taken into account:

• Environmental Features: sparse distribution of terminals (such as warehouses) or high-density Wireless Access (such as meeting rooms and multi-function halls) outside or indoors ).
• Installation Method: ceiling, panel, or 86 box.
• Power Supply Mode: Standard PoE (802.3af or 802.3at), Passive PoE or DC (DC power supply ).
• Coverage: A single room, multiple rooms, area coverage, fixed-point coverage, and high-density coverage.
• Number of terminals: 10, 20, 30, or 50 terminals are connected to a single AP.

2. Take the hotel environment as an Example

AP layout in the lobby: the lobby space is large and there are few obstacles. You can deploy a ceiling AP based on the size of the lobby.

AP layout of guest rooms: General wall-mounted or panel-type AP can ensure the best wireless coverage and provide the best accommodation experience. Restaurant AP layout: catering, conference rooms, and other personnel-intensive areas use ceiling-and dual-band wireless APs that support high-density access to meet the needs of simultaneous access by multiple people. Note: Both the lobby and dining room mentioned above use the ceiling AP deployment, but there is a difference. The Lobby adopts the ordinary 2.4G ceiling style, while the dining room has higher requirements and must use the dual-band Ceiling style.

3. How to select a single frequency or dual frequency?　

After the application is completed, let's talk about the frequency selection. How can we determine the frequency selection for the 2.4G AP and 5.8G AP?

Although not all mobile phones support g Wi-Fi, we recommend dual-band Wireless AP for better wireless experience, especially in personnel-intensive areas.

4. How many clients does an AP have?

Based on the working principle of wireless products and the wireless sending and receiving capabilities of Wireless terminals such as mobile phones, a Wireless AP can achieve "one kilometer, access to hundreds of people. Generally, a single-frequency AP has 20 ~ 25 clients, one dual-band AP with 40 ~ 60 clients.

5. What is the appropriate range of AP coverage?

The coverage of Wireless AP is closely related to the installation location and actual environment. The following information is provided for your reference:

• Ceiling Wireless AP: it covers 6 surrounding rooms/dormitories, or a radius of about 12 meters. It is suitable for installation in environments with an open environment and a height not less than 3 meters. Due to the characteristics of the installation method, wireless blind spots are easily generated.
• Panel Wireless AP: covers 2 surrounding rooms/dormitories and 1-2 wall spaces. Better wireless coverage.

6. Avoid these mistakes

Think that expensive performance is good, buy expensive will not be wrong: may be confused by exaggerated advertising effect, will only increase costs.

The higher the wireless transmit power of the AP, the faster the Internet access: other factors need to be considered. It is not wise to pursue a high-power product. The ability to penetrate the wall is strong, and the speed of surfing the Internet must be fast: the ability to penetrate the wall does not mean that the coverage is far away or there are a large number of hosts.

As long as the Wireless AP hardware performance is good, there is no need to worry about anything else: the hardware is just the foundation and powerful software functions are required.

The higher the transmission rate of a Wireless AP, the better: You still need to check the network bandwidth. If the network bandwidth is small, the AP rate of Mbps will not go anywhere.

Summary

When selecting a Wireless AP, you need to take into account the AP parameters, user access volume, coverage, and software functions, as well as the power, stability, and on-site environment, focuses on "balance ".
