Characterisations of wirless link quality and sampling rate. a Different throughput values for sampling rates of 1.43 ksps/channel without UART, 1.25 ksps/channel without UART, 400 sps/channel with UART and 385 sps/channel with UART. Measurements were taken for a total of seven channels during a period of 20 minutes. b Connection quality is measured as the number of packages lost for the different sampling rates. When using UART the connection is stable for 385 sps/channel but fails for 400 sps/channel and higher; Otherwise the connection is stable for 1.25 ksps/channel but starts becoming lossy at 1.43 ksps/channel
