5G/LTE Interference Solutions: Advanced Filtering Technology
As 5G and LTE networks continue to expand across South Africa, satellite operators face increasing challenges with signal interference. Telemedia is proud to introduce our comprehensive range of 5G/LTE interference filters, designed to protect your satellite communications from unwanted terrestrial signals.
The Challenge
The rollout of 5G networks in the C-band spectrum (3.4-3.8 GHz) creates potential interference with satellite downlink frequencies (3.7-4.2 GHz). This overlap can cause:
- Signal degradation
- Complete loss of satellite reception
- Intermittent service disruptions
- Reduced system performance
Our Solution
Telemedia offers a complete range of professional-grade filters designed to eliminate 5G/LTE interference while maintaining optimal satellite signal quality.

Installation Guidelines
Site Survey
- Identify potential 5G/LTE interference sources
- Measure existing interference levels
- Determine optimal filter placement
- Calculate required rejection levels
Filter Selection
- Urban areas: Recommend TM-5G-WG for maximum rejection
- Suburban areas: TM-5G-PLL provides integrated solution
- Rural areas: TM-5G-IF may be sufficient
Installation Best Practices
- Install filters as close to the antenna as possible
- Ensure proper weatherproofing of all connections
- Use low-loss cables for IF connections
- Verify system performance after installation
