The most normal thing is that the same router with external antennas and internal antennas always have the same coverage, but if in a router with internal antennas we put obstacles near it, logically it will be affected by them and they will provide less coverage. For this reason, many router manufacturers design them to stand upright and not put books on top of it, which is dangerous for both router cooling and WiFi coverage.
With the launch of the WiFi 4 standard, MIMO Multiple Input Multiple Output was launched, a technology that allows us to take advantage of more than one antenna to communicate simultaneously with a specific wireless client. This means that if a router has two antennas regardless of whether they are internal or external , it allows a WiFi client with two antennas to use both simultaneously for twice the speed.
The same happens if we have a router with three antennas and a WiFi client with three antennas, we will have triple the speed than if we used a single antenna.
A very important detail is that if a router has four antennas and the WiFi client only has two, then logically they will only be able to communicate with two antennas, but the other two remaining antennas of the router can be used by another WiFi client to send and receive data in how long the one currently transmitting ends. Therefore, a greater number of antennas will allow us a greater capacity of simultaneously connected WiFi clients.
A router that has a total of four antennas and supports MU-MIMO will be able to transfer data to the following clients simultaneously:. But if we connect WiFi clients with only one antenna, we could transfer data to up to four clients simultaneously. A very important detail is that, currently, the maximum number of antennas that we have available in top-of-the-range domestic routers is four antennas for each WiFi frequency band. Routers with internal antennas, there is no possibility of moving them anywhere, what is recommended is to leave the area where we are going to place the router free, so as not to have additional obstacles and that the WiFi signal reaches better.
Regarding external antennas, depending on how many antennas the router has and the design of the equipment, the most normal thing is to place them differently and not all vertically, to try to radiate in all directions as if it were a sphere. However, both MIMO and Beamforming technology will work together to always provide us with the best coverage, even if we have the antennas vertically. If you are in an environment where the coverage is really weak, it is possible that in this case it is worth moving the antennas to try to improve the coverage received by wireless clients.
In outdoor spaces, if a router has one or more antennas, we will not notice much improvement in terms of coverage. But indoors it is critical that a router incorporates two or more antennas, to take advantage of both the MIMO and MU-MIMO technologies that we have explained before, as well as to take advantage of the Beamforming technology.
If our router has two or more antennas for each frequency band, we can take advantage of all these technologies. Share Tweet. Fiona Hutcheson Hi.

If your wireless router is against an outside wall of your home, the signal will be weak on the other side of your home. Tip 2. Put your wireless router at a certain height. It is better to place the wireless router on a table or shelf and keep it at a certain height so that the omnidirectional antenna's transmitting ability can be utilized.
According to our actual situation, we suggest that the table should be about Actual test case sharing:. For an actual height test, we placed the router at a height of 6 ft. On Android, when we use the phone at a normal height On Android, when we hold the phone up to a 6 feet level. Note: The smaller negative number is better performance, eg, the Signal Strength will be better than the Signal Strength Tip 3. As we know, our antenna signals are radiated vertically and outward. If you only need to use it on the first floor of your home, we recommend you place antennas vertically, so that the antenna coverage can achieve the best on the same level.
We did a test on the effect of antenna placement on horizontal radio. If your router needs to be hung on the wall for use.
The antenna is placed vertically and then the wireless signal strength is received by the iPhone in the horizontal plane. Signal Strength The antenna is completely horizontal. So, if you only need to use it on the first floor in your home, or hanging on the wall to use the router in a horizontal direction, we recommend that you put the router antenna vertically.
Considering various requirements, we recommend the following antenna placement methods. Because it is not conducive to wireless model transmission in the horizontal direction. Tip 4. Stay away from high-powered appliances. When the router transmitting signals, the high-power electrical appliances, and iron products may cause interference to Wi-Fi, so try to avoid microwave oven, weak current box, TV, and other electrical appliances.
Tip 5. Avoid obstructions. In order to keep it neat, a lot of friends put the router in a cabinet.
