To purchase a wireless route product, refer to "three points"

With the rapid development of the routing industry, many families are using wireless routing products, such as wireless routers and wireless APs, which are in high demand. Here, we mainly analyze what needs to be paid attention to when purchasing wireless routing products. The wireless network market seems vague, but this does not mean that there is no chance. In addition, from the current trend, the application and popularization of wireless technology will be the trend of the times.

Taking Zhongguancun electronic store as an example, there are a lot of businesses operating on wireless networks, and the price war is becoming increasingly fierce. Even consumers feel the cruelty of market competition. As a consumer, how can we choose a suitable wireless routing product for our rapidly developing wireless technology has become a very real problem. What details and skills should we pay attention to when purchasing wireless routing products?

I. Viewing speed

Nowadays, people have higher requirements on network speed even than cars, as do wireless networks. The transmission speed of a wireless route product depends on the standard protocol. To learn about the wireless speed, we have to talk about the wireless protocol standards first. So far, the protocol standards of wireless networks have gone through three stages: IEEE802.11a, IEEE802.11b, and IEEE802.11g. Due to compatibility issues, IEEE802.11a has been eliminated early, and the wireless routing products represented by IEEE802.11b are also basically "evaporation" due to speed disadvantages ", currently, 54M wireless routing products using IEEE802.11g Protocol have become the mainstream.

In addition, we can see that the ipvm product is the product of the Super G produced by the manufacturer after the spread spectrum, including the 125M wireless product, including the Super G ipvm product, it should be regarded as a transitional product on the road to IEEE802.11n. There is no doubt that the speed of the wireless route is determined by your needs. For home users, 54M wireless products should be a good choice. According to the current market conditions, 54M wireless routes have entered a mature stage, while the performance is constantly improving, the average price of more than 200 yuan is also consistent with the psychological price of home users.

Wireless products such as 108 M and M are more suitable for SOHO or enterprise users, in addition to meeting user needs in terms of speed, some additional features and security are not comparable to those of 54M wireless routing products. However, in terms of price, the average prices of 108 M and M products are about twice that of 54M products.

Ii. view the appearance

As the saying goes: A person cannot look like a person. However, we pay more attention to the "appearance" of the wireless routing product when purchasing it. First of all, we can intuitively feel the style of this product from the aspects of exterior design, tone matching and volume, and make a visual effect score. Secondly, we can get a rough idea about the technical quality of the shell material of the wireless router product. At present, the shell design of the wireless router is mostly made of plastic or metal. Finally, I suggest you pay close attention to the heat dissipation port of the wireless routing product. For network products in long-term working conditions, the advantages and disadvantages of the Heat Dissipation Capacity will directly affect the product stability and service life, so by carefully observing the shell material, heat sink port and volume, we will probably get some information about the product's heat dissipation performance. Of course, this is also one of the best methods to detect wireless routing products before purchase.

3. view the antenna

Antenna is a crucial component for wireless routing products. Its quality has a direct impact on wireless routing products. So what do we rely on to determine whether the antenna is good or bad? It can be said that the antenna is a signal amplifier, which expands the reception and transmission of signals, while the gain of the antenna determines whether the signal can achieve better results within a certain range, therefore, antenna gain should be a factor that we should consider.

We usually refer to the antenna gain. The unit of measurement of the gain is dBi. The larger the gain, the better the signal sending and receiving. At the same time, the antenna gain is related not only to the antenna size, but also to the materials inside the antenna and the workmanship. Currently, most of the products on the market are 2dBi and 5dBi, but for home users, 5dBi antennas are enough, such as 8dBi and 16dBi high-gain antennas, mostly used in large environments, such as office buildings.
