What is Typical Range of Wireless Network

When we use a wireless network, the first thing that comes to our minds is the range.


The range of wireless network will help you get uninterrupted connectivity in every corner of your room. So, what is the typical range of wireless network? Let us have a look.



Factors Affecting Range of a Wireless Network




Range of a wireless network depends on different factors that include the number of access points as well as the type of wireless router used.

In a normal setting, a typical home based router can easily cover a small family. However, if you are using a wireless network for a small office or a large business, then you will need to build grids of access points all over the building.

The range of a wireless network also depends on the device used. The range of devices is affected by the following factors:

  • The 802.11 protocol it runs on
  • The strength of the device transmitter
  • The nature of the different physical obstructions such as concrete walls or stainless steel cupboards
  • Radio interference in its range such as home appliances like microwaves or different wireless routers from the surrounding neighbours



General Range of a Typical Wireless Network


After taking into consideration the various factors, the typical range of wireless network working on a 2.4 GHz band can reach about 46 meters, that is, 150 feet indoors. The same wireless network kept in an open area (outdoors) can reach a range of 92 meters, that is, 300 feet.

Old router models such as the 802.11a routers that used the 5 GHz bands could reach about 1/3rd of the above distance. The latest models of routers today that use dual band, that is, 2.4 GHz and 5 GHz simultaneously have better range than the previous models.

It has been found the 5 GHz WiFi connections are easily affected by the obstructions in the house. This includes brick walls, metal frames, etc. that can cause reduction in range up to 25%.

In case of residential buildings, routers using 2.4GHz radios are more susceptible to congestion and crowding. This is because most of the common appliances around the house use the 2.4GHz range. Thus, affecting the range as well as causing connectivity issues.

Conclusion


The 2.4GHz band will give you a better range of wireless network but with a slower speed. If you opt for a 5GHz band, you will get about 10 to 15 feet of range as it cannot penetrate hard or solid objects such as walls. However, it allows faster data transmission for uploading and downloading data.
