Abstract: Several implementations of an access point, an application server, and instances of an application operating upon a cell phone are disclosed. These implementations support the cell phone and its application traveling on a vehicle, which wirelessly communicates through a wireless router, such as a Bluetooth router with an access point situated in a cabinet to direct a traffic controller driving a traffic light. The wireless router responds to a cell phone initiated by the app, by reporting the location and speed of the vehicle, often further including the vehicle type, such as a bicycle or heavy truck. The traffic controller may lengthen a green light in response to a heavy truck, to reduce wear on roadways. The access point may respond to a bicycle, by confirming its presence to the bicycle driver as well as adjust the traffic controller.

Abstract: A method of cellular communication among a subscriber unit, a base station and a switch controller is provided which comprises the steps of digitally encoding speech signals at the subscriber unit; generating radio forward error correction (FEC) at the subscriber unit to protect the encoded speech signals during transmission; transmitting the encoded speech signals together with the radio FEC by radio from the subscriber unit to the base station; error correcting the transmitted encoded speech signals at the base station using the radio FEC; generating wire FEC to protect the encoded speech signals during transmission; transmitting the encoded speech signals together with the wire FEC from the base station to the controller; error correcting the transmitted encoded speech signals at the controller using the wire FEC; and decoding the digitally encoded speech signals at the controller.

Abstract: An equalization method for digitally encoded signals transmitted in a plurality of non-contiguous time slots has a digitally encoded synchronization signal commencing in each time slot followed by a digitally encoded data signal having a digitally encoded marker signal at a predetermined time period. The synchronization signal of the assigned time slot ("first synchronization signal") and the digitally encoded data signal of the assigned time slot including the marker signal, and the digitally encoded synchronization signal of the immediately succeeding non-assigned time slot ("second synchronization signal") are all stored. The location of the minimum energy point of the stored digitally encoded signals is determined. Equalization is performed starting from the first synchronization signal to the minimum energy point. Then, the equalization commences from the second synchronization signal backwards until the minimum energy point is reached.
