RF Optimization for Both Transmitter – Receiver

WHY RF OPTIMIZATION
- Suitable propagation Model-Path loss model  
- Traffic capacity – Hot Spot
- Coverage both indoor & outdoor
- Balanced between up link - Down link
- Co located transmitters & receivers
- Co located w/ other antennas

INTERFERENCE :
- Adjacent channel interference 
- Co channel interference
- Inter-modulation
- Transmitter EIRP to low
- Receiver sensitivity
- Voice quality - BER 
- Man made structures -Dynamic
- Growing up - City - Town
- Emerging data & video streaming
- Transmitter RF leakages

LINEARITY OF RF POWER AMPLIFIER : 
- Spurious
- Spectral

RF OPTIMIZATION FOR BOTH TRANSMITTER – RECEIVER

- Transmitter optimization
- Increase EIRP & RF power output
- Improve transmitter stability
- Improve transmitter noise rejection
- Antennas height & Spacing – for optimum space diversity

INTERCONNECTION ANTENNA – FEEDER – JUMPER : 
- Obtain optimum lowest VSWR
- Antennas RF isolation

RECEIVER OPTIMIZATION

- Remove - Interference & Intermodulation. 
- Improve receiver system sensitivity & selectivity
- Improve rejection of external noise & unwanted signals

CONVENTIONAL – TRUNKING REPEATER :
- Optimize coverage both down link - up link
- Repeaters RF optimization, TX and RX
- Indoor coverage
- Increase repeater duty cycle
- Increase HT – Portables talk time
