Theoretically, the routers that can cover an area with a diameter of more than 2000 square feet are called long-range routers but practically, long-range routers are routers that can cover and provide a good signal in every area of an entire house that has a floor space of about 1500 square feet.
In general and as a simple comparison, with a long-range router, users can still receive a good and strong signal behind the thick walls of the house while users who use a normal router cannot receive a good signal.
First , Check the WiFi Signal Level.
As mentioned in this article, you can check the signal strength at any area of your house or workplace by installing a simple app called “WiFi Analyzer” on your smartphone. This app displays the WiFi signal strength in real-time using visual methods and charts.

The average WiFi signal strength is about -80dBm to -35dBm (dBm is the unit for measuring signal strength). A larger number (a number closer to zero) means a higher signal strength. Your signal strength shouldn’t be less than -65dBm if you want to have good, high-quality service.
Now you can check if your router is a long-range router or not by simply using this method:
“If your signal strength in all areas of a large house or office is about -65dBm, then your router is probably a long-range one.”
What are the Benefits of a long range Router?
As it’s obvious, a long-range router covers a much larger area compared to a regular router. Covering the entirety of a large office or house is only possible by using a long-range router. Otherwise, you’d have to use two or even three regular routers to cover the entire area of your office or house.

Using two or three regular routers instead of just one long-range router can cause some issues, such as:
- The routers may conflict with each other.
- Connecting all of these routers to the main modem is in itself a technical challenge and it usually greatly reduces the connection quality.
- Users that move between the “borders” of these routers coverage area, keep getting disconnected ( Yellow Area )

What’s the Difference Between Long-Range Routers and Regular Routers?
From a technical standpoint, there’s a few differences between a long-range and regular router:
1- The Difference in Output Strength
The output strength of regular routers is usually between 100mw(20dBm) and 250mw(23dBm) while in long-range routers, it’s around 500mw(27dBm) to 800mw(29dBm).
2- The Difference in Antenna Gain
Normally, the antenna in regular routers has a gain of 2dBi (dBi is the unit for measuring antenna strength) while the antenna in long-range routers has a gain of 5dBi. The higher the gain in an antenna, the larger the size so you can easily distinguish a 2dBi antenna from a 5dBi one.
3- The Difference in Number of Antenna
Increasing the number of the antenna on a router increases the signal strength and speed of the router. A long-range router serves a high number of users so it should have a higher number of antennas compared to a regular router. This way, optimal quality and speed for all of the users are guaranteed. Regular routers have one or two antennas while long-range routers have more than three.
4- Beamforming Feature
Beamforming is a special technology that greatly increases the coverage and speed of the network. Not all long-range routers have this feature but high-level and main brands use this technology in their long-range routers. The interesting point about this technology is that using it can almost double the coverage of the router.
5- More Processing Power
Since a long-range router covers a larger area than a normal router, it can serve a higher number of users and devices. For this reason, most long-range routers are equipped with a more powerful processor (and memory ) than regular routers.
