License Free Private Wireless

Interference Mitigation

There is a large amount of license free spectrum available to deploy private wireless networks for industrial IoT use-cases. Additionally, governments around the world are aggressively making new frequency bands license free to meet the demand. However, the primary concern is interference with other users. Doodle Labs has optimized it’s Mesh Rider technology to mitigate the interference so our customers can take advantage of these license free bands and deploy reliable, fast, low latency, and secure private wireless networks.

Why Private Wireless Networks

Low latency, high reliability, high security and high speed, are the main reasons to consider private wireless. The public LTE network uses traffic management policies so that a very large number of people and enterprises can share the same network. Hence the user experienced latency, speed and traffic prioritization suffer. On the other hand, private wireless networks are dedicated and provide full management control for an enterprise’s critical operations. The enterprise can control the traffic priority for each machine, each sensor and each user to access the network. Enterprise’s data never leaves the private network and remains secure.

With over 20 years experience in developing private wireless networking products, Doodle Labs has identified many scenarios where benefits of a license free wireless network can be realized. The table below takes a quick look at the industries and use-cases that can benefit from the availability of free private wireless.

Interference Avoidance
State-of-the-Art RF

State-of-the-art COFDM and MIMO technology for exceptional multi-path and NrLOS performance in harsh, noisy environments. Mesh Rider provides spectral scan and channel selection across the entire mesh network to avoid interference.

Low Latency C&C

The Mesh Rider’s Ultra Reliable Low Latency Channel (URLLC) provides reliability and low latency that is simply not possible with public LTE networks. All URLLC traffic is transported with special priority for latency as low as 3-30ms.

License Free Bands

The Smart Radios are available in form factor compatible license free 915 MHz, 2.4 GHz and 5.8 GHz license free bands for global applications. 

The Smart Radios are available even in the newly released CBRS innovation band. Check out our Mesh Rider solution for the CBRS band.

Mobile Mesh

Self-forming and self-healing multi-hop relay capabilities of Mesh Rider improves the robustness, extends the penetration and provides adaptive coverage in the deep obstruction zones.

Optimized 4K Video

Mesh Rider has advanced channel for streaming low latency, crystal clear 4k multi-cast video.

Encryption and immunity against cyber attacks

Many applications transmit highly sensitive data. Communications must be secure and the network must be protected from unintended parties gaining access.

Regulatory Certifications

Smart Radios are modular certified in many countries so that our customers can readily start deploying the regulatory compliant license free private wireless networks.

Rugged MIL specs

Smart Radios have been deployed in some of the harshest conditions on Earth. They are certified to work through extreme temperatures and high vibration.


Private networks with Mesh Rider technology can be deployed with low capital investment. They have virtually zero operating costs in stark contrast to the recurring monthly cost of using the public LTE network.

License Free Bands

Frequency RangeDescriptionView Specs
902-928 MHz
License Free Band – USA, Canada, Mexico, Central, South and Latin Americas, Australia, New Zealand, and China

The 900 MHz band is license-free for use in many countries around the world. At lower frequencies, the radio signals can travel farther and penetrate through the walls and vegetation, providing better NrLOS operation. The 900 MHz band provides an excellent alternative to the crowded 2.4 GHz Wi-Fi band for long-range links.
