CC1101 Network for Healthcare Cyber Physical System on Air Quality Data Acquisition

There is currently no dedicated network for IoT needs on the Siliwangi University campus, IoT device data communication still relies on the wifi network for internet network needs, which means that the quality of data transmission will be compromised if the network is overloaded with internet users. Siliwangi University needs a suitable, practical, and good network so that it can be used as a data communication line by the installed IoT devices. The viability of setting up an interconnection network on the Siliwangi University campus needs to be examined. In this study, the effectiveness of the CC1101 network used by Siliwangi University to monitor air quality via the Internet of Things was evaluated. The system consists of two components: nodes and gateways. The nodes use Arduino Nano microcontroller boards to transmit air quality data to the gateway, while the gateway uses a nodeMCU ESP8266 microcontroller board to transmit the data to the internet. According to the test findings for the CC1101 using the 433 MHz frequency, the most data that can be transferred is 64 bytes, and it can transmit data up to a distance of 68 m under line-of-sight conditions and 40 m under non-line-of-sight conditions. The data collected shows that there is an average data transmission delay of 859.698 ms and a packet loss of 3.12%.
