What is the difference between Rx Lev Full and Rx Lev Sub ? What you mean by Link Budget? Can you explain ?
Answer : RX Lev Full means Mobile transmit the measurement…
RX Lev Full :
- RX Lev Full means Mobile transmit the measurement report(SACCH multiframe) for every 480ms.
- This multiframe containes 104 TDMA frames, in 104 TDMA frames 4 TDMA frames for Decode the BSIC and remaining 100 TDMA frames for Average measurment of serving cell and neighbouring cell.
- This average measurment of 100 TDMA frames are RX Lev Full.
RX Lev Sub :
- DTX is a discontinuous trasmission, When the mobile conversation 40% of the time either Transmitter or Receive is idle. When DTX is ON, DTX will switch off the Transmitter or Receiver when they is no speech Pulses.
- Only few TDMA frames will transmit, the average of this TDMA frames is called RX Lev Sub, give you proper measurement of RX level.
Link Budget :
- A link budget is accounting of all of the gains and losses from the transmitter, through the medium (free space, cable, waveguide, fiber, etc.) to the receiver in a telecommunication system.
