Remote Radio Head (RRH) controlling software

This product is dedicated to the RRH (Remote Radio Head) controlling software. RRH is a part of a Radio HW that is used in radio towers to convert digital user data into an over-the-air signal and vice versa.

Project background

As of today, 5G, or the fifth generation wireless is the most advanced mobile broadband technology standard. It hit the market in 2019 and took over 4G/LTE technology.  

According to the latest statistics, 5G connections will make over half of total mobile connections in North America, Asia Pacific, and China in 2025. Moreover, in 2025, automotive applications and consumer electronics are predicted to make up about 21.7 % of the global 5G infrastructure market, while industrial apps will account for just over 20 %.

Our client’s platform allows end-users to rapidly address evolving radio telecommunication technologies, including 5G solutions, and to significantly reduce time-to-market and time-to-revenue. 

Our client required a platform to facilitate rapid development of Remote Radio Unit (RRU) wireless transceivers, used to convert from wireless to wireline communications.

Business needs

Our client required a platform to facilitate rapid development of Remote Radio Unit (RRU) wireless transceivers, used to convert from wireless to wireline communications. 

Leveraging this platform allows the end-users of our client to rapidly address evolving radio telecommunication technologies (including 5G communication solutions), and to significantly reduce time-to-market and time-to-revenue. 

Our client was looking for: 

  • Senior developers with strong C/C++ expertise, experience with embedded applications development, legacy code support, Linux user-space, YANG, and acquainted w/RFC documentation, NETCONF, and git; 
  • A development team able to work flexible hours to provide EST time zone support (at least up to 9pm EST);  
  • Experts with a degree in radio technologies; 
  • Developers with hands-on embedded experience, deep understanding of client-server interactions, strong debugging abilities, Unit Testing, and Multi-threading.
Solution

We developed a flexible, modular software package (OS, launcher, watchdog, main application, and test systems) for setting up, operating, and detecting errors in a radio tower with support for all promising, and existing communication standards.

  • Provision of feature content and bug fixes in accordance with specifications
  • On-demand support to other teams (mostly EST time zone), which may include, but is not limited to, facilitation of debugging efforts, supplying guidelines, and providing walkthrough demos
Client values
  1. We gathered the required development team with the needed skill set fast, within only a few weeks.
  2. We are working on a solution that allows the end-users of our client to respond more rapidly to evolving markets and to reduce the duration of product development lifecycles.
  3. Our solution helps reduce time-to-market and time-to-revenue through the use of 5G technology.
  4. We provide our client with an easily configurable and extensible platform to facilitate the development of RRU’s for the distinct hardware solutions of a varying range of customers.

Testimonials

I think we can see the power of programming in full when ten top-level developers gather in one team for a long-term project. This way they can share their experience in solving truly tough problems and come up with really cool solutions. Such projects are the greatest luck and skills boost in a developer’s life. Happy I got the chance to join such a project. Without too many big words, we are creating the technologies of the future! I can boast now that I was a part of the great team that designed the radio tower for 5G. Pretty impressive, isn't it?
