Technology has come a long way in recent years, and this is especially true when it comes to wireless networking. One of the most impressive advances in this area is the ability of wireless networks to now extend as far as 30 miles. This is thanks to a variety of different technologies that have come together to make this possible. In this article, we will take a look at some of the key technologies that enable wireless networks to extend over such long distances.

What is a Wireless Network?

A wireless network is a computer network that uses wireless data connections between network nodes. A node can be a computer, printer, or any other device with built-in networking capabilities. Wireless networks are often used to connect devices that are not physically connected to the network, such as laptops and smartphones.

What is the Range of a Wireless Network?

One of the most common questions we get here at CU Boulder OIT Wireless Engineering is “What is the range of a wireless network?” The answer, unfortunately, is not nearly as straightforward as many people would like it to be. A number of factors – including (but not limited to) terrain, weather, obstructions, and interference – can all affect the range of a wireless network.

That being said, there are some general principles that can help give us a ballpark estimate for the range of a typical wireless network. For starters, 802.11b/g/n networks typically have a range of about 30-100 meters (100-300 feet) indoors; in outdoor open-air spaces with no obstructions, this range can be extended to several kilometers.

Of course, as with everything in life, your mileage may vary; in some cases, you may be able to extend your range even further with the help of specialized equipment such as directional antennas or amplifier/repeater units.

How Does Technology Enable Wireless Networks to Extend Their Range?

Wireless networks rely on a variety of technologies to enable them to extend their range. One of the most important is Multiple Input Multiple Output (MIMO) technology. MIMO uses multiple antennas to transmit and receive data, which allows for a more efficient use of the available spectrum and enables wireless networks to extend their range. Other technologies that are used to extend the range of wireless networks include repeaters, reflectors, and amplifiers.

What are the Benefits of Having a Wireless Network with a Long Range?

Wireless networking has a number of benefits over traditional wired networking, including increased flexibility, portability, and scalability. One of the key benefits of wireless networking is the ability to extend the network range to cover large areas. With the right technology in place, a wireless network can easily span over 30 miles.

There are a few different technologies that can be used to extend the range of a wireless network. One of the most popular is known as mesh networking. Mesh networking involves installing a series of nodes, or access points, across the area that needs to be covered. These nodes then communicate with each other wirelessly to relay information back and forth. This type of setup is often used in large businesses or public spaces where there is a need to cover a very large area.

Another technology that can be used to extend the range of a wireless network is known as point-to-point (P2P) bridging. P2P bridging involves connecting two wireless access points together using specialized radio equipment. This type of setup is often used in situations where it is not practical to install multiple nodes, such as when spanning long distances between two buildings.

No matter what technology is used, extending the range of a wireless network can offer many benefits. Longer range networks are more versatile and can be used in more situations. They are also more reliable since there are fewer “blind spots” where coverage is not available. If you need to cover a large area with your wireless network, talk to your IT professional about the best way to extend your network’s range.

What are the Disadvantages of Having a Wireless Network with a Long Range?

While wireless networks with a long range have many advantages, there are also some disadvantages to consider. One of the biggest disadvantages is that they can be more expensive to set up and maintain than shorter range networks. Additionally, long range wireless networks can be more susceptible to interference from other electronic devices, weather conditions, and physical obstructions. Finally, because they cover a wider area, it can be more difficult to troubleshoot and manage a long range wireless network.

What are the Applications of a Wireless Network with a Long Range?

While the 802.11 standard only allows for a maximum range of about 300 feet, there are a number of technologies that can be used to extend the range of a wireless network to up to 30 miles. Here are some of the most common applications for a long range wireless network:

-Backhaul for cellular networks: A long range wireless network can be used to connect a cell tower to the rest of the cellular network, eliminating the need for expensive and difficult-to-deploy fiber optic cables.

-Connecting remote locations: A long range wireless network can be used to connect two or more locations that are far apart, such as two office buildings or a school and a library.

-Wireless video surveillance: A long range wireless network can be used to connect security cameras to a central monitoring station, allowing for real-time monitoring of large areas.

-WiFi hot spots: A long range wireless network can be used to provide WiFi access in public areas such as parks, airports, and coffee shops.

How Do I Set Up a Wireless Network with a Long Range?

Extending the range of a wireless network can be accomplished in a variety of ways. One popular method is to purchase a wireless repeater, which takes the signal from an existing wireless router and amplifies it, then broadcasts the signal over a wider area. Another common solution is to add a second wireless router to act as a range extender; this can be accomplished by connecting the two routers with an Ethernet cable and configuring one of them as an access point.

In some cases, it may be possible to extend the range of a wireless network by making changes to the router’s firmware or adjusting the antenna. If you are using a Wi-Fi router with external antennas, you can try pointing the antennas in different directions to see if that gives you better coverage. You can also check for firmware updates that may improve your router’s range or allow it to work better with repeaters and range extenders.

What Are the Best Practices for Setting Up a Wireless Network with a Long Range?

The best practices for setting up a wireless network with a long range are to use a high-gain antenna, to select the proper frequency band, and to reduce interference from other devices. A high-gain antenna will increase the signal strength and allow the network to extend further. The best frequency band for long-range wireless networking is the 5GHz band, which has less interference than the 2.4GHz band. To reduce interference from other devices, it is important to use a channel that is not being used by nearby networks.


The range of a wireless network is determined by a number of factors, chief among them being the type of antennae used. Wireless networks using directional antennae can extend their range up to 30 miles, while those using omnidirectional antennae are limited to a range of about 3 miles. Other factors that affect range include terrain, weather, and interference from other electronic devices.
