Abstract: A first communication device stores a transmission rate table including response times, and transmission rates associated with the response times, each first response time indicating a time for transmitting test data between the first and second communication devices, while transmitting load data between any pair of communication devices at one of different transmission rates. The first communication device determine a necessary transmission rate for actual data; detect a response time indicating a time for transmitting the test data between the first and second communication devices; determine a transmission rate associated with the response time, as a used transmission rate, based on the transmission rate table; determine an effective remaining transmission rate based on a maximum transmission rate of the communication network and the used transmission rate; and start transmission of the actual data when the effective remaining transmission rate is higher than the necessary transmission rate.

Abstract: A communication device for transmitting data to a plurality of radio terminals in radio communication includes: a first communication interface that performs radio communication with each of radio terminals in accordance with a first communication standard; and a controller that controls radio communication with each of the radio terminals, wherein the controller manages a modulation and coding scheme (MCS) level indicating a level of an MCS used for transmission of data for each of the radio terminals in association with a load amount indicating a communication load in the transmission of the data, wherein the controller, when detecting that the load amount is greater than a predetermined upper limit value, determines an allowable level of the MCS level corresponding to a load amount less than the upper limit value, and restricts the transmission of the data to use an MCS level equal to or higher than the allowable level.

Abstract: A controller receives first or second equipment identifier from a first wireless communication apparatus, by using one wireless communication circuit of the third and fourth wireless communication circuit. When the one wireless communication circuit is the fourth wireless communication circuit, the controller sets an encryption key information for wireless communications with the first wireless communication apparatus, to encryption key information including an equipment identifier that does not coincide with a received equipment identifier among the received plurality of encryption key information, and controls the third wireless communication circuit to transmit and receive encrypted transmission data to and from the first wireless communication apparatus by using key data included in set encryption key information.
