The upcoming 5G era is undeniable as it brings enormous performance improvements that will change the global communications market. To meet the change, the base station, smaller cells shall be widely increased in the different areas. Besides, all communication relative products like data storage, antennas, wireless devices, and so on that shall be upgraded as well.

5G refers to 5th Generation Mobile Networks and compared to 4G LTE, 5G outstands in coverage, spectrum efficiency and low latency. 5G system must achieve the following capabilities: Transmission rate of 10Gbps, coverage over 100,000 users and connection speed 100 times faster than 4G.

Base Station
Most of the 5G system is expanded on top of the existing 4G equipment and implements new technologies like mmWave and array module. The power consumption of 5G is soaring three times up to 11577W compared to 4G’s 6877W, this brings greater challenges to heat dissipation. In addition, high frequency and faster connection speed, cell base station’s limited space has resulted in heating power and a technical bottleneck. How to optimize the limited spaces would be a significant issue since well-designed thermal management is the foundation of 5G system reliability, reduction of future maintainance cost and prolonging life span.

Small Cells
5G small cells are designed to fit in available space such as on top of a light pole, building rooftops, traffic lights or utility poles. They can be installed in a rugged environment with outdoor temperature up to 60 celsius.

Small cells’ heat dissipations can easily reach 40W to 200W and due to constraints space, the components inside the system must be small and dissipate low heat. At times, a battery backup might be required in case of a power outage. Owning to the factors above, passive cooling is an ideal thermal solution, such as the heat sink soldered with vapor chamber or embedded with heat pipes and thermal module.
5G hubs dissipate heat around 7W to 10W. For low heat dissipation, thermal pad or graphite can easily solve the heat issue whereas heat sinks and heat pipes are for higher ones.
