OpenVoice: Low-cost mobile wireless communication project for rural area based on OpenWRT

Communication is one of essential elements of a life included the people who live at rural areas. However, in fact telecommunications in rural area get a lot of constraints such as expensive infrastructure, difficult terrain and electrical problem. In this paper, we offer a design of mobile wireless communication based on openWRT as solution for communication in rural areas. This design combines VoIP technology and mesh ad-hoc network implemented on embedded device with openWRT as main firmware. With this technique, we will get a lot of advantages such as mobility, flexibility, low-cost development and implement, and low power consumption. In this paper, we also take measurements from OpenVoice prototype to determine the ability and realibility if handled voice communication.
