PURPOSE:To provide a communication method realizable with inexpensive device while reducing operations for establishing synchronization in low-speed frequency hopping type frequency spread communication. CONSTITUTION:For each session, hopping synchronization is established in a step 1-1. In the step 1-2, the communication of one frame is performed. In the step 1-3, whether or not the communication of the entire frames included in one session is completed is inspected and the step 1-2 is repeated without performing the operation for establishing the hopping synchronization until the communication of the entire frames included in one session is completed. As a result, since the operation for establishing the synchronization is performed only once at first during one session, data communication efficiency is improved. |
