Revolution in Signal Iduna Park: 5G network for 82,000 fans under construction!

The exciting race for the 5G adoption not only kept the communication providers, but also the technology in general. According to RCR Wireless report, 5G is becoming increasingly popular worldwide, and the network operators are faced with the challenge of both expand and remain profitable. It is important to take into account the circumstances of our modern world: About 80 % of mobile traffic takes place inside - a fact that the network infrastructure presents challenges.

Large venues, such as sports stadiums, encounter an enormous increase in capacity requirements at events. A promising solution to the challenges of the interior supply is the combination of open ran 5G architectures with neutral, distributed antenna systems (DAS). This integration enables communication service providers to optimize the transition between far -reaching networks and interior networks, which significantly improves capacity, cover and reliability.

innovations in stadium networking

A shining example creates the Signal Iduna Park in Dortmund, Germany. There is an upgrade work to improve the mobile cover for up to 82,000 fans. According to RCR Wireless, the stadium is a real crowd puller and holds the European average visit of 1.37 million fans over 17 games in the 2011-2012 season. The upcoming DAS implementation will support both LTE and 5G connectivity for all four major German network operators.

An essential part of the in-house network includes multi-beamed antennas and over 150 remote radio units to guarantee high-speed cover. The design provides for medium -strong radios for 30 sectors, supplemented by weak and strongly powerful radios that are strategically positioned indoors, inputs and parking spaces.

Another remarkable progress is that 1 & 1 Telecommunications implement the world's first 5G open ran stadium network, using Rakuten Symphony’s RAN architecture. This open RAN setup needs significantly less space-just two rack units compared to conventional setups that need 300 square foot.

advantages of Open Ran

What makes open ran so attractive? The answer to this provides SOLID: With lower latency times, higher data rates and greater reliability, 5G brings exciting options for companies. Private 5G networks in particular offer robust solutions for Industry 4.0 and IIoT. They enable efficient, administrative and safe EDGE connectivity, which contributes significantly to the cost reduction and flexibility.

In addition, the Solid O-RAN technology has been proven in its agility and efficiency in private 5G networks. It enables the cost -effective use of the Citizens Broadband Radio Service (CBRS) spectrum and supports various architectures such as 4G LTE and 5G New Radio.

Open as an approach is a future-oriented, disaggregated approach for the provision of mobile Fronthaul and Midhaul networks. This concept completes the Next Generation RAN architecture and creates space for innovations such as network slicing and secure firmware updates across the air. This leaves even the old LTE networks more efficiently and opens up numerous options for new applications and services, from autonomous vehicles to IoT applications.

in a world in which 5G connections could grow to 8.3 billion by 2029 forecasted, it is clear that the challenges for expanding networks, while costs and complexity are managed. In order to cope with the innovative requirements, companies such as the O-Ran Alliance, which counts over 1601 members, have the goal of further developing the NG-RAN philosophies and defining a variety of open standards. Open Ran thus becomes a catalyst for the mobile networking of the future.
