Abstract
A method of controlling operation of an end device using a one-way radio broadcast includes sending an encrypted message from a client application of a computing device to a first network server, sending the encrypted message from the first network server to a second server included with radio broadcast automation equipment, transmitting the encrypted message in a radio broadcast signal using one or more radio broadcast transmitters, receiving the radio broadcast signal at an end device, and decrypting the encrypted message using the end device. The encrypted message includes control information to control operation of the end device.
Claims21
A method of controlling operation of an end device using a one-way radio broadcast, the method comprising:
- sending an encrypted message and geographical target information from a client application of a computing device to a first network server, wherein the encrypted message includes control information to control operation of an end device;
- sending the encrypted message and the geographical target information from the first network server to a second server included with radio broadcast automation equipment, wherein the second server is operatively coupled to a plurality of one-way radio broadcast transmitters;
- commanding, by the first network server, the second server to select, one or more of the plurality of one-way radio broadcast transmitters that have broadcast regions that correspond with the geographical target information;
- transmitting the encrypted message from the second server only to the selected one or more of the plurality of one-way radio broadcast transmitters;
- and
- transmitting, by the one or more of the plurality of one-way radio broadcast transmitters, the encrypted message in a radio broadcast signal to the end device;
- wherein sending the encrypted message includes sending an encrypted message that includes an identifier of the end device, the identifier identifying the particular end device;
- and
- wherein the first network server is included in an Internet of Things (IoT) cloud and the end device is an IoT device.
A backend system that provides a one-way data transmission service, the system comprising:
- a first network server;
- a second server included with radio broadcast automation equipment, wherein the second server is operatively coupled to a plurality of one-way radio broadcast transmitters;
- wherein the first network server is configured to receive an encrypted message and geographical target information from a client application and send the encrypted message and the geographical target information to the second server;
- wherein the first network server is further configured to command the second server to select one or more of the plurality of one-way radio broadcast transmitters that have broadcast regions that correspond with the geographical target information;
- wherein the first network server is included in an Internet of Things (IoT) network cloud and is further configured to encode the encrypted message to include an identifier of one end device, the identifier identifying the particular one end device;
- wherein the second server is configured to initiate transmission of the encrypted message with the control information in a radio broadcast signal to the one end device using the selected one or more one-way radio broadcast transmitters, wherein the encrypted message includes control information to control operation of the one end device;
- wherein the identifier allows the one end device to decrypt the encrypted message when the identifier is a match for the respective end device;
- and
- wherein the one end device is an IoT device.
