Is it faster with 2 antennas or 4 antennas? I believe there must be many friends who are swaying around because of the “antenna” problem when choosing a router, and they can’t make up their minds. Let’s take Huawei Router A1 as an example, let’s talk about those things between the chat line and the router!

 

Which is faster, internal antenna or external antenna?

To answer this question, you might as well take a look at the status quo and differences between external antennas and internal antennas: external antennas appeared earlier than internal antennas. Early wireless router antennas were basically external; in recent years, internal antennas It has become popular, and all mainstream manufacturers have introduced routers with built-in antennas. Due to the built-in antenna, the appearance of the router is more fashionable and concise, and it is more in line with the aesthetics of modern people.

 

The angle of the external antenna can be adjusted, and the different placement of the antenna has a greater impact on the performance and network speed of the router. If the angle is not placed properly, it will affect the user’s Internet experience; and the built-in antenna is designed to be optimized by default. No need for user adjustment.

 

External antennas are easier to implement. If you encounter complex scenarios and environments, there are more solutions; built-in antennas must take into account the optimal space and antenna performance, which is relatively difficult to implement and requires manufacturers to have higher capabilities.

 

In fact, the internal and external antennas are just a solution to the router antenna design. Under current technical conditions, the router will not simply differ due to the internal or external antennas and the signal. Therefore, whether the external antenna or the internal antenna should not be the primary consideration when choosing a router.

 

What is the relationship between the wireless protocol and the number of antennas?

When choosing a router, users should pay more attention to the wireless protocol and the number of antennas, because they directly determine the Wi-Fi transmission rate.

 

Through official promotional materials, you can basically calculate the Wi-Fi rate of Huawei Router A1.

11ac 2*2 in the data indicates that it supports 802.11ac and 2 antennas, so the Wi-Fi rate is 433.3*2=866.6. 11n 2*2 indicates that it supports 802.11n and 2 antennas, so the Wi-Fi rate is 150*2 =300. The total of the two is 1167.6 (Gigabit), rounded to about 1200Mbps. The “Gigabit WiFi”, “Gigabit wireless router”, and “11AC technology” promoted by Huawei refer to this.

 

If you master the relationship between the wireless protocol and the number of antennas, you can easily avoid the various “pits” of the merchants when choosing a router in the future. For example, if a router claims to support Gigabit, it must support 11ac. If it does not support 11ac, it is definitely false propaganda! Another example is the number of router antennas (assuming 4), but only the highest rate of 300Mbps, which means that it actually only needs 2 11n antennas (2*150=300), and the extra two antennas are very likely It’s just a display, used to bluff people and increase their worth!

 

Should the router choose a product with a relatively high price and configuration?

Whether it is necessary to buy a higher-end wireless router depends on the cost performance of the product and the actual needs of users. The main consideration here is the home broadband and the size of the apartment. At present, the home broadband in most areas in China is 100M and below, and you can choose a dual-band route of 1200M. If the home broadband is greater than 100M, you need to choose dual Gigabit routers, such as Huawei Router A1 Enjoy Edition, can give full play to every megabit speed of ultra-100M fiber. Of course, if it is a large apartment with an area of ​​more than 120 square meters, multiple routers need to be used for intelligent networking to achieve seamless Wi-Fi coverage throughout the house.

 

Knowing yourself and the enemy can survive all battles. I believe that after understanding the relationship between routers and antennas, friends will be more calm and wise, less entangled and hesitate when buying routers in the future!
