What is an EARFCN calculator?

An EARFCN (E-UTRA Absolute Radio Frequency Channel Number) calculator converts between channel numbers and actual frequencies used in LTE and 5G networks. It helps network engineers identify the exact frequency a cell is operating on.

How do I calculate antenna tilt?

Antenna tilt is calculated based on antenna height, desired coverage radius, and signal propagation characteristics. Mechanical tilt physically adjusts the antenna angle, while electrical tilt uses phase shifting. Proper tilt optimization improves coverage and reduces interference.
