WiFi enabled LTE small cell gateway is a type of a base station. Base station uses cellular wireless network for communicating with mobile phones or terminals. Base station connects mobile phones to a wireless carrier network and offers local coverage for a wireless network. The area of coverage varies from several miles to few city blocks. Each base station is typically owned by one carrier or wireless company and gives coverage only for that company’s network. It may also offer roaming coverage for other networks in case carriers have agreement for roaming and technology is compatible.
It’ll be very interesting to see how this plays out in terms of security. WiFi enabled gateways will definitely introduce phreaking vulnerabilities that aren’t really an issue with LTE repeaters.
On the other hand, high-level surveillance will be changed forever. People can conceivably be tracked through way more interesting (and detailed) means than triangulation. Any device that’s part of the “internet of things”, and announces itself as such, can be instantly traced in real-time as opposed to having to analyze logs after-the-fact. (Assuming that this functionality is included with infrastructure setup, and depending on how involved a given government is with their infrastructure/carriers.)
