Communication radio terminal for communication system, has module for transmitting and receiving wake-up signal over frequency channel, where another module transmits and receives data signal over another frequency channel

摘要

The communication radio terminal (100) has a module (110) for transmitting and receiving a wake-up signal over a frequency channel, where another module (120) is provided for transmitting and receiving a data signal over another frequency channel. The former frequency channel is formed in a high frequency band than the latter frequency channel. The frequency band of the former frequency channel amounts 2 to 2.6 gigahertz, and the frequency band of the latter frequency channel amounts 950 megahertz or less. Independent claims are included for the following: (1) a communication system with a server; and (2) a method for operating a communication system.
