4G LTE Drone Technology


Walkera 4G LTE Drone Technology by Ambar Group

The increasing popularity of drone technology is very evident in China and the US. Once exclusively used in military applications, today UAV’s can be used for aerial photography and as a hobbyist’s toy.

It’s continuous development can be credited to the fact that it is an open source technology for the most part. Even if you are not a professional UAV pilot, knowing how to operate one and understanding its pros and cons is enough to get you hooked.

Recently, 4G LTE drones have been making waves. For most of its existence, drones or UAV’s are radio-controlled. It’s basically an RC aircraft piloted using a hand-held radio transmitter.

It is remote controlled with the transmitter communicating with the receiver in the UAV that sends signals to the servos to control the craft. Here comes the downside. The maximum distance of commercial UAV’s is 5 miles tops if you have a big antenna on the transmitter. Otherwise, it is usually less than 5 miles. We are talking about drones used by civilians and those for photography.

If you insist on flying your drone beyond the max distance, you may end up losing your craft. Even though we say civilian used drones nowadays are inexpensive – we say that relative to the price when the technology just started to take off.

To avoid this incident from happening, most UAV’s are manufactured with a flight control system with a fail safe. Once the drone loses connection with the transmitter, it will return to its home point.

You are not likely to lose your drone, but the problem regarding the max distance remains. This is where 4G network connection comes in.

It is an alternative to the radio control system that can eliminate the rather short distances a drone can be controlled. In terms of using a drone for search and rescue missions, the 4G network allows a drone to fly several miles away from the controller or pilot.

Many drone enthusiasts are trying out a single board CPU to control their drone copters.

A joint venture between two reputable companies is developing a widely acclaimed 4G drone technology that we should not only mention, but look closely at. The result of these giant team-up are drone technology innovations for many applications.

Ambar Group and Walkera Cooperation

The Ambar Group, a drone tech company based in Israel, is known for developing latest technical solutions for drones used in professional aerial photography, civilian use, agriculture, engineering and military and police use, serving governments and various industries.

Walkera by Ambar uses 4G mobile Internet to fly drones without the 5 mile distance limit.

Ambar and Walkera’s joint cooperation brought forth the LTE Drone Series using the LTE Drone Management Software which is a huge market success.

The idea is to make your UAV fly even farther with a 4G network connection. 4G connection allows more data per user than previous generations.

The distance improvement in turn improves the efficiency of drone applications. Replacing the standard radio control feature of drones with 4G LTE network connection has several advantages experienced while in flight.

Advantages of 4G LTE Drones

First and foremost, the 4G LTE drones were developed to answer the common problems that 2.4 and 5.8 GHz communications often encounter. If you have been flying your UAV in urban areas using a 2.4 or 5.8 GHz, you know that the issue is the high SNR or signal to noise ratio.

Walkera 4G LTE drones are not affected with this because the control or communication is powered by 4G LTE mobile internet with 2.4 GHz for backup. We all know that 4G connection is more stable in urban areas which means this is a perfect real-world solution for radio-controlled drones. In rural areas as well, we are seeing a large improvement in mobile internet because of LTE networks. This means, flying a drone in large urban or rural areas won’t be a problem as far as SNR is concerned.

This eliminates the distance limit and the only concern you’ll have left is how long the battery’s power is going to last when flying and especially when transmitting images.

The 4G LTE drones by Walkera and Ambar are operated and controlled, transmitting images, from two separate locations that have mobile internet with 4G LTE networks.


As the Walkera and Ambar drones continue to improve its flight control efficiency, it’s applications grow unlimited as well in the following fields:

  • Civilian use such as professional aerial photography
  • Military reconnaissance, surveillance and unmanned cargo,
  • Public safety in terms of search and rescue, security and surveillance,
  • Science and research,
  • Agriculture,
  • Mining,
  • Mapping and Surveys
  • And more.

It’s safe to say that 4G LTE and UAV technology work well together. For existing and future applications, we can expect enhanced performance from Walkera 4G Drones.
