The race is on to install 5G sites all over the world. But a 5G access point requires two to three times more power than a 4G site - and every engineer knows that more power consumption means more heat is generated. Active cooling is expensive and can be difficult to implement at the remote sites typical for telecom applications.
It may seem counterintuitive to start thinking about heat control at the integrated circuit level rather than at the board level. However, telecom infrastructure uses components in sufficient quantities that a small improvement in thermal management during construction can create big aggregate improvements.
