Mobile-to-mobile convergence (MMC) is a technology that facilitates the interoperability of mobile communications devices without the need for any fixed capabilities or proprietary service provider. In MMC, a single cellular telephone, smartphone or softphone-equipped device can switch automatically between Wi-Fi and cellular networks.
Mobile-to-mobile convergence offers an alternative to conventional cellular and wireless solutions. A network incorporating MMC offers features such as:
- Functionality with the existing private branch exchange (PBX)
- Interoperability with a wide-area network (WAN)
- Support of dual-mode devices
- Ability to maintain control in a workforce that employs mobile devices exclusively
- Seamless roaming among Wi-Fi and cellular networks
- Continuous access to multiple applications including voice, e-mail, instant messaging (IM) and customer relationship management (CRM).
Mobile-to-mobile convergence differs from fixed-mobile convergence (FMC) in which a specific service provider is employed to enable seamless handoff between Wi-Fi and cellular systems. The first practical MMC solution was developed and made widely available by DiVitas Networks, based in Mountain View, California.
