Table 8: Radio specifications
Table 9 shows the Highway NLoS (Non-line-of-sight) channel parameters that are used to obtain the receiver
sensitivity values in Table 8. This channel was used in RF testing at the third ETSI Plug test (CMS3).
Each tap is faded using Pure Doppler, but the second antenna has a Doppler increased by 11 Hz, which prevents
phase synchronization of channels. The RX Power listed in Table 8 refers to the power of Tap 0.
The values presented are typical values, measured at +25 °C.
