Classic guide for enterprises to buy wireless routers

With the rapid development of wireless technology, wireless routers are more widely used. So I have studied how to buy a suitable wireless router for enterprises. I would like to share with you here and hope it will be useful to you. Wireless network technology is becoming increasingly popular. Wireless technology can be seen at airports, trains, office buildings, and coffee shops. Wireless Internet access is also addictive like smoking. For this reason, many CEOs are also unwilling to lag behind. They are frequent visitors to airports and coffee shops. After experiencing the convenience brought by wireless Internet access, they will return to the Enterprise and start to deploy their own wireless networks. Indeed, the infinite network can bring great convenience and freedom to the user. As long as the user experiences the wireless network technology, it is difficult for the user to abandon it.

However, after some enterprises deploy wireless networks, enterprise managers find that the effect is not as good as that in airports and other places. This is mainly because the airport is relatively wide and there are basically no closed places in the terminal. Therefore, the wireless signal will be better. However, in enterprises, as offices are independent of each other, there is a relatively closed space. Therefore, the signal transmission is blocked, affecting the performance of the wireless network. Therefore, the wireless routing technology can avoid spider-like network cables of enterprises and keep enterprises' offices clean and tidy, so that users are not bound by network cables. However, network administrators need to implement wireless network technology in enterprises, which is not as convenient as in the airport terminal. The network administrator must consider the limitations of the location. Different routers have different adaptability to the environment. Therefore, network engineers need to select a router suitable for their own enterprise environment. However, it is really difficult to select a suitable wireless router for your company among a wide range of wireless router products. The more types of products, the more choices the network administrator can choose, but it will make the enterprise unable to adapt.

I have also had several selection experiences of wireless routers. In general, the network administrator must master some wireless router testing methods. During the selection of wireless routers, the data provided by some manufacturers basically has little reference value. Rather, enterprises should conduct scientific tests based on their actual conditions. Only in this way can we obtain scientific data support for our decisions.

I. Selection of Test Platform

Most enterprises may not have wireless NICs on their desktops before deploying wireless networks. The re-purchase of wireless NICs also requires a lot of investment. With the development of Intel's technology and the increasing popularity of laptops, wireless networks of many enterprises are mainly designed for laptops. For example, my company will not assign expensive wireless network cards to all desktop hosts. Now we are basically eliminating desktop computers. Therefore, it is best to use the current mainstream operating platform of the enterprise for testing. In the future, I plan to use a laptop to replace a bulky desktop computer, so I tested it with a laptop. This can better reflect the compatibility between devices. After all, Intel's technology is absolutely mainstream in the current situation.

In addition, if you use a desktop computer for testing, there is another disadvantage. Because nowadays, desktop computers are usually placed in the corner of the desk, and some even use cabinets. The signal is poor because of unnecessary barrier. Therefore, unless enterprises want to implement wireless networks based on desktop computers (which is not recommended by the author), it is better to choose laptops with strong mobility for testing.

2. The key is penetration testing.

Nowadays, mainstream wireless routers often claim that the indoor distance can reach 100 meters and the outdoor distance can reach 400 meters. However, the author can be responsible for everyone, and this value does not have much reference value for enterprises. This value has a precondition, that is, 100 meters of non-partitioned space or open-air open space. This harsh condition may only be met in some public places, such as the airport and bus station terminals and waiting rooms. For enterprises, due to space restrictions, offices are often isolated into independent areas. Therefore, this transmission distance is of little reference value to enterprises. Therefore, the network administrator also needs to perform some penetration tests based on the layout of the enterprise.

First, test the signal of the glass partition. This is because the office of the company is mainly partitioned by HEMP glass. The manager's office and general clerks are divided into relatively sealed spaces by glass. In addition, since each independent office has an air conditioner, the door is usually closed. Therefore, a test is required. The test method is also very simple. Avoid the tested wireless router in a large external office. Then, test the signal and traffic in the office. For example, Microsoft has a wireless signal detector in its operating system. It is like a mobile phone. It will grade the signal at multiple levels. This function can be used to determine the strength of wireless signals.

Second, test the same office signal. In the same spacious office, the signal strength is acceptable generally because there is no barrier. So why do we still need to test it? This is mainly because the wireless signal is the same as the mobile phone signal and is easily disturbed. If the signal is disturbed, the signal strength is weak. As I have tested, if the enterprise office prevents two wireless routers of different brands at the same time, the wireless signal of a vro will be disturbed. Even if there is no blocking, only two signals are displayed on the operating system. If you disable another wireless router, the signal can reach the full range. Therefore, if an enterprise already has a wireless router and wants to deploy another wireless router to improve the coverage of the wireless network, it is best to perform this failover test. Check whether the new wireless router conflicts with the original device.
