For the past year, we've researched and investigated the radio over cellular space, also known as Push-to-Talk Over Cellular, or PoC. We've encountered dozens of "pop up" U.S. companies selling China engineered, manufactured, and hosted devices for extremely low prices.
The devices are advertised as encrypted and marketed and sold to businesses and government agencies.
We estimate millions of these devices are currently in operation. From our research, we've found that many of these companies' claims are misleading or false. For example, one Chinese manufacturer white labels its products under numerous U.S. names, and claims that the servers hosting its radios are on Amazon servers in the U.S. In reality, they are hosted by Alibaba, the Chinese tech conglomerate and are vulnerable to Chinese spying by sending back user data to China. more
