5G is hot – just a little too hot for connected devices
- Monday | 14th October, 2019
Probably not hot enough to ignite your battery (probably), but enough to generate a definite burning sensation in your pants pockets. In a paper published last year three researchers at the Huazhong University of Science and Technology wrote:“the heat dissipation of smartphones restricts the maximum receiving rate of smartphones. Thus, smartphones cannot sustain the original receiving rate and may even have to shut off wireless communications.” This is obviously not an optimal outcome. This is already happening with the first mmWave 5G rollouts (what AT&T calls 5G+) — which, remember, is not the one that involves mmWave radios: The Wall Street Journal wrote in July that their Galaxy S10’s 5G switched off in the Icelandic summer. However, many potential impacts triggered by the maximum receiving rate of smartphones have not yet been investigated.
