Converts RF signals into optical or digital signals over fiber optic or Cat6 cabling, converting them back to RF at remote radio units near the antennas.
Designing a system that supports 2G, 3G, and 4G simultaneously requires careful handling of interference management, antenna placement, and frequency planning. 4G/LTE, in particular, requires higher Signal-to-Interference-plus-Noise Ratio (SINR) to achieve high throughput, making interference management crucial.

A successful deployment follows a strict engineering lifecycle detailed in the text: The principles of cabling, link budgeting, and interference
Even as we move into the 5G era, the fundamental physics of radio propagation detailed in the 3rd edition remain the same. The principles of cabling, link budgeting, and interference management are the building blocks upon which modern 5G indoor systems are designed.
To implement 2x2 MIMO successfully indoors, planners must deploy dual-polarized antennas or two separate physical antenna runs. The paths must maintain low cross-correlation to allow the receiver to distinguish between the two parallel data streams.
Chapter 7 of the guide emphasizes that noise (thermal and system-generated) is a fundamental constraint in any communication system. 3. Technology-Specific Considerations (2G, 3G, 4G) 3G/HSPA Challenges:
