2190-4 is a multi-purpose cellular transceiver or modem standard, designed for short-distance wireless communications. The application field covers a wide spectrum, from low data rate transmission to handovers, and from real-time sensor data to video-streaming. The range of applications is very wide, and thus it is important to understand the basics of how 2190-4 actually works.

The general working principles of this standard are built around the broadcast of digital information packets, either to a single device or to multiple devices in an area. These data packets contain the instructions necessary to complete a specific task or to transfer the data being sent. This data is then received and processed by the receiving device, depending on the specifics of the application being executed.

There are several different types of applications that use 2190-4 for digital communication, including telemetry, streaming video, home automation, and point of sale (POS) transactions among others. The range of applications is broad and diverse, making 2190-4 a versatile and cost-effective choice for short-range wireless communication.

For instance, telemetry applications use the standard to transmit sensor readings or reports to a central location. This could include temperature readings, wind speeds or rainfall measurements. With the telemetry application, the remote sensors constantly send data to the central location, allowing for remote monitoring and control of the area.

Streaming video uses 2190-4 to send the digital video from one location to another. This is useful for video surveillance, while also allowing for instantaneous viewing of the video feed. Home automation systems use 2190-4 to control devices such as lighting, heating, and security systems from a single location. These systems require real-time information, as any delays can have serious consequences if the wrong command is sent.

Finally, POS transactions use 2190-4 to securely transmit credit card information from a retail outlet to a processing center. This requires a secure encryption protocol to ensure that the sensitive data is not compromised. All of these applications can be integrated and managed using the 2190-4 standard, offering a comprehensive solution for short-range wireless communication.

In summary, 2190-4 is a multi-purpose cellular transceiver or modem standard, designed for short-distance wireless communications. It can be used to transmit sensor readings, streaming video, home automation commands, and POS transactions. Its versatility makes it an attractive choice for an array of applications, including telemetry, video streaming, home automation, and secure data transmission.
