Technology Set
RS-485 Communication | Utilized for reliable serial data transmission between the motor-driven antenna and the base station, RS-485 supports long-distance communications and multiple devices on the same bus, making it ideal for the RET's network communication needs. |
BeagleBone Black Microprocessor | This compact yet powerful microprocessor performs the control and supervisory functions necessary to manage the RET system, offering the flexibility and processing capability required for efficient operation. |
AISG Protocol | The Antenna Interface Standards Group protocol is employed to standardize the communication between antenna control systems and equipment, ensuring compatibility and functionality across different devices and systems. |
Applications for Desktop Linux | Developed to provide robust and user-friendly control interfaces for the RET system from desktop computers running Linux, facilitating easy and efficient management. |
Applications for Embedded Linux | Tailored for devices with limited resources, these applications run on embedded systems to control and monitor the RET system directly from the hardware, ensuring seamless operation in various environments. |
GUI Host Application Software | This graphical user interface application is designed to support test implementations, allowing engineers and technicians to interact with the RET system intuitively for setup, monitoring, and troubleshooting. |
Qt GUI Application for Remote Tilting Control | Provides a user-friendly graphical interface for controlling antenna tilt remotely, designed using the Qt framework known for its cross-platform capabilities. |
Multithreaded Daemon on BeagleBone Black | A background service that runs on the BeagleBone Black, handling tasks concurrently to ensure responsive and reliable control of the antenna system. |
Queued Processing of Packets Between OSI Layers | Manages data packets efficiently, queuing them for processing in a systematic manner to maintain order and integrity of communications. |
Debug Mode with Hex View of All Packet Traffic | Offers a detailed view of the packet flow in hexadecimal format, useful for debugging and ensuring accurate data transmission. |
Fine Tuning of HDLC Protocol Parameters with Configuration File | Allows for precise adjustments to the High-Level Data Link Control (HDLC) protocol settings via a configuration file, optimizing communication according to specific needs and conditions. |
Solution
The solution is comprised of a motor-driven antenna with communication to the BTS via RS-485 and a microprocessor that controls the communication and performs supervisory functions. Most of the RET systems use the AISG protocol (Antenna Interface Standard Group) which is an open specification for the control interface of these systems.
Our software solution facilitated the communication between a host computer and the motor-driven antenna through the RS-485 protocol and BeagleBone Black microprocessor performing control and supervisory functions.
Software packages developed by us included:
1) Applications for desktop Linux.
2) Applications for embedded Linux.
Our solution also provided a GUI host application software to support the test implementation.
