![]() They provide highly accurate network synchronization but come with their set of limitations. GNSS solutions deploy GPS receivers together with the base station antennas. There are two main methods to deliver synchronization to base stations and small cells in today’s mobile networks, Global Navigation Satellite System (GNSS) such as the Global Positioning System (GPS) and Precision Time Protocol (PTP). GPS-based synchronization solutions come with compromises The synchronization requirements cover both neighboring base stations and devices across the network. Moreover, new features and advanced network techniques such Massive MIMO, Carrier Aggregation (CA), License Assisted Access (LAA), and Coordinated Multi-Point (CoMP) transmission and reception technologies require further enhancements in synchronization. With 5G comes an increased focus on TDD (Time Division Duplex) technology, which requires a much tighter synchronization, compared to, for example, FDD (Frequency Division Duplex) as in most 4G/LTE networks. While the requirements for 4G/LTE network synchronization are quite demanding, the launch of 5G is bringing new and more stringent synchronization expectations for mobile networks. Network synchronization is a critical function for mobile networks, driven by the demands for higher capacity and speed for new applications and services. Why is 5G network synchronization critical? This is the perfect time for operators to consider technology solutions that can help them achieve network synchronization quickly, securely, and cost-effectively. In 2022, we will be seeing an increasing number of telco companies leveraging 5G synchronization to ensure they’re ahead of the 5G rollout curve. ![]() According to a report by Kearney (April 2020), the synchronization cost is estimated between 3-5% of the total 5G network rollout cost, i.e., $1.5-2.5 billion in 2027 and can in many cases require a large forklift upgrade of old infrastructure to enable PTP network synchronization - this is prohibitive for a large number of operators. However, so far, this requires investment which raises 5G rollout costs quite significantly. Telecoms operators around the world are therefore facing the pressing need to deliver accurate and secure 5G synchronization across their networks. Without precise and accurate time synchronization, the 5G services cease to work and a faulty synchronized base station will interfere with the 5G operations of other operators as well. Time synchronization is critical for 5G to function. 5G networks are set to handle new mission critical applications, including real-time industrial applications, autonomous cars and bluelight communication. The 5G infrastructure market is growing exponentially with a CAGR of 60% and is estimated to reach a total market size of about $50 billion by 2027. However, there is a set of requirements that need to be fulfilled for 5G rollout to speed up and take place cost-efficiently nationally. The promise of super-fast, low-latency bandwidth is transforming all industries and sectors, opening up new use cases and opportunities for innovation. ![]() ![]() 5G is here and is changing how we communicate, work, and play. ![]()
