A method and apparatus for improving a network is described. The network
uses the energy from a vehicle battery or vehicle generator to power an
intermediate transmitter device that receives the signal from a portable
wireless device and retransmits the information in the signal to a base
station. The intermediate transmitter device also receives information
from the base station and retransmits the information to the portable
wireless device. The described system expands the areas in which a
wireless device may be used.
