Engineering:Mobile-to-mobile convergence
Mobile-to-mobile convergence (MMC) is a technology that allows a mobile device to automatically switch between a Wi-Fi network and a cellular network without interrupting a voice call or data session.[1] The technology is especially useful in terms of lowering cost, providing wider coverage and provides more raw data.[2]
In an MMC system, a dual-mode handset equipped with a software client can detect available Wi-Fi networks and route voice calls and data through them as the primary connection. If the Wi-Fi signal weakens or is lost, the system automatically switches between the WiFi connection and the cellular network without manual help.[1] This is different from fixed-mobile convergence (FMC), which typically requires a service provider to permit the handoff between WiFi and 4G/5G mobile networks.[1]
History
The mid-2000s saw the first major push to commercialize mobile-to-mobile convergence. DiVitas Networks allowed enterprise users to seamlessly hand off calls between a corporate PBX over Wi-Fi and the public cellular network.[3] Early users noticed an improved voice quality on Wi-Fi but also highlighted flaws such as short battery life, unreliable roaming, and complex setup.[4]
