mobile-to-mobile convergence (MMC)

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.
