Abstract [en]

The field of automation and smart devices is currently expanding. As most devices require wireless communication, the market for low budget, low power radios is growing rapidly. Many applications, such as the remote control of machines, have real time requirements with minimal latency. In this report, the market of wireless chips in the sub-GHz region has been investigated in order to give Syntronic AB an insight of the current market. Several key features such as range, data rate and output power were ranked among the available chips. To provide Syntronic with a marketing tool when reaching out to customers in the remote control field, a demonstration prototype (demo) was implemented using one of the radio chips from the list. The demo shows real time requirements with low latency between two wireless nodes. The first node takes movement data from a computer mouse and transmits it to the other node controlling an array of light emitting diodes (LEDs). This report contains the selection of radio configurations, design of a new wireless communications protocol, and implementation of the system in hardware and software. Measurements show a latency of 3.6 ms and a range of approximately 450 m which is regarded satisfactory.
