Closing of receive window calculations missing 4.25

[JacoTuks]

Expected Behavior

According to The LoRa Modem Designer's guide, the duration of a preamble is (nPreamble + 4.25)*Tsym but in class-a-end-device-lorawan-mac.cc the +4.25 is omitted.

Actual Behavior

Both receive windows are scheduled to close too fast.

Code in question

class-a-end-device-lorawan-mac.cc

1. m_closeFirstWindow = Simulator::Schedule (Seconds (m_receiveWindowDurationInSymbols*tSym), &ClassAEndDeviceLorawanMac::CloseFirstReceiveWindow, this); //m_receiveWindowDuration

2. m_closeSecondWindow = Simulator::Schedule (Seconds (m_receiveWindowDurationInSymbols*tSym), &ClassAEndDeviceLorawanMac::CloseSecondReceiveWindow, this);
