1. A wireless communication system by which an in-vehicle wireless communication device and a wireless communication device perform wireless communication with each other, the in-vehicle wireless communication device being mounted in a vehicle and including a first wireless communication unit for performing wireless communication with the outside of the vehicle and a first processing unit for performing processing relating to communication, and the wireless communication device being installed outside of the vehicle and including a second wireless communication unit for performing wireless communication with the vehicle and a second processing unit for performing processing relating to communication,
wherein
the first processing unit of the in-vehicle wireless communication device determines a communication amount of data transmitted and received via an in-vehicle network of the vehicle and calculates a free capacity based on difference between the communication amount in the in-vehicle network and a communication capacity of the in-vehicle network,
the first wireless communication unit of the in-vehicle wireless communication device transmits communication amount information including information on the calculated free capacity to the wireless communication device,
the second wireless communication unit of the wireless communication device receives the communication amount information transmitted by the in-vehicle wireless communication device,
the second processing unit of the wireless communication device adjusts the size of data to be transmitted to the in-vehicle wireless communication device according to the free capacity, and
the second wireless communication unit further transmits the data with the size adjusted by the second processing unit to the in-vehicle wireless communication device.
