Report calls out Huawei's 5G modem chip for its size and inefficiency

A new report from analytical firm IHS Markit (via Venture Beat) reveals that Huawei's 5G modem chip, like the one it is employing on the Huawei Mate 20 X 5G, is inefficient and too large. This has resulted in the production of a device that is bigger and less energy efficient than it could have been. The phone, the manufacturer's first to support the next generation of wireless connectivity, is powered by the company's own Kirin 980 SoC and also is equipped with its in-house Balong 5000 5G modem chip. Both were designed by Huawei's Hi-Silicon unit but manufactured by foundry TSMC.
But this inefficiency won't last too long. The report says that by next year, smartphone processors will have integrated 5G/4G/3G/2G multimode modems. This could lead to lower prices for 5G handsets since a separate modem won't be necessary. This will also eliminate the need for memory and power management chips that were being used just for the 5G modem chip. And lower prices will lead to more widespread adoption of 5G.
Huawei did some things right, says the report. Even though there is some duplication between the Balong 5G modem chip and the integrated modem inside the Kirin 980, the Mate 20 X 5G relies on just one modem (the Balong 5G modem chip). However, it does have separate 4G and 5G radio tuners, something IHS Markit expects to be integrated into one radio in the future.
