Communication networks are the central nervous system of the 21st century economy. The fifth generation of wireless—5G—will be essential to and inseparable from all we do. In many ways, we are already there. What for most was an abstract concept became all too real during the COVID-19 crisis.
The coronavirus pandemic has underscored the critical importance of communication networks: They are integral to our daily lives and our ability to function economically and as a society. Shutdowns of offices, schools, and stores have meant turning to apps to work, learn, and buy. Frontline medical workers and vaccine researchers have consulted colleagues via teleconference to get the latest insight and advice on combating the virus. Being connected means resilience, coping, surviving.
Getting 5G right is all the more urgent. Next-generation 5G networks will enable telemedicine, self-driving cars, and a proliferation of Internet of Things devices to fuel the future digital economy. Secure, reliable 5G networks will be essential elements of national infrastructure. Policymakers in Australia, Japan, and Vietnam understood this early on and took decisive action to secure their 5G networks. U.S. officials, slower out of the gates, are now the loudest voice on the risks of having equipment from untrusted vendors in 5G networks. The spotlight is brightest on the risks that Huawei poses to national security, including the threat of espionage or disruption. Given the Chinese Community Party’s ability to exercise control over Huawei, there is justifiable concern over data integrity on networks that deploy Huawei equipment. More serious is the potential to use 5G equipment as a vector to cripple critical infrastructure. Such risk is not only about communications—5G will be the backbone of controls needed for power grids, water supplies, and transportation infrastructure. Despite this, the United States has had only limited success convincing its allies to join it in banning Huawei.
