Decision Factors

This article reports the findings of a mobile communications survey mailed out to over 2,000 trucking firms. The findings indicate that 68% of respondents use some form of mobile communication system in their firm. Various types of mobile communication systems were reported, including two-way pagers, one-way pagers, cell phones, two-way radio, and satellite communications. Additionally, implementation decision factors for mobile communication systems were evaluated for both users and non-users of mobile communication systems.

To address the problem of wireless communication system existing blind spots in mine tunnels, this paper proposes a novel mine mobile communication systems without blind zones, based on Ethernet Passive Optical Network (EPON) and Radio on Fiber (RoF) technologies, which adopts WiFi, WiMAX and other wireless interface, as well as leaky antenna and distributed antenna. The key technical elements for designing the mine mobile communication system are clarified, and the system components and the dual-bus-shaped network structure are presented. Also, the operating principle and the features of the system are analyzed. In addition, the trend of the technology related to the future mine mobile communication system is presented.
