1. A computing system comprising: a communication unit including a microelectronic configured to: communicate a cell location A without a grid location A for identifying one of grid cells where a current location A is located, communicate a cell location B with a grid location B for identifying one of grid areas with one of the grid cells where a current location B is located, and a control unit including a processor, coupled to the communication unit, configured to: generate a grid identification prediction based on predicting a grid identification of one of the grid areas where the cell location A is located nearest to the cell location B, and generate a proximity result based on the grid identification prediction matching the grid location A for determining whether the current location A is near the current location B.
