How many lbbp boards can be configured in a base station?

The number of LBBP boards to be configured in a base station that supports LTE depends on the number of cells, bandwidths, antenna configurations, and the number of CPRI ports to be supported by the base station. Each BBU working in LTE mode needs to be configured with at least one LBBP and each LBBP supports six RF modules.

Why are base stations important?

In modern communication networks, base stations, as core infrastructure, are crucial for stable operation.

How many WBBP boards can be configured in a base station?

The number of WBBP boards to be configured in a base station depends on the number of cells, number of uplink and downlink CEs, signaling processing capability, and number of CPRI ports to be supported by the base station.
