Data transmission through a short-range radio system is prevented, during the time period (t2-t1), when data is being transmitted through a long-range radio system. Data is transmitted through the short-range radio system only when data is not being transmitted through the long-range radio system. The data to be transmitted through the short-range radio system is delayed until the data transmission through the long-range radio system is completed, and then transmitted. |
