Mobile base station communication power generation

What are the primary sources of power for a mobile base-station?

The primary sources of power for these mobile base-station vary by region and can generally be categorized into 3 buckets: Reliable grid power: AC mains or grid power can reliably serve as the primary power supply.

What is the main source of power for a base station?

In the case of base stations situated in regions with bad-grid or off-grid power availability, the predominant source of power for the base stations is diesel generators. [4,6] Diesel generation is costly in both the procurement of fuel and travel required to maintain adequate fuel levels at the base stations.

How does a mobile station communicate with a base station?

The communications between mobile station and base station occur concurrently via two air interface channels from each base station separately. Both channels (signals) are received at the mobile station by maximal combining Rake processing (see Figure 11.20 ). Soft handoff occurs in about 20–40% of calls. Figure 11.20. Soft handoff in CDMA.

How much energy does a cellular base-station consume?

Less well known is that about 0.5% of the global energy supply is consumed by mobile communications infrastructure, alone, [6,7] Among the mobile communications infrastructure, cellular base-stations have the largest appetite, consuming around 80% of total power, in studies completed of 2G and 3G networks, and of 3G and 4G networks. [6,8]

What is the impact of base stations?

The impact of the Base Stations comes from the combination of the power consumption of the equipment itself (up to 1500 Watts for a nowadays macro base station) multiplied by the number of deployed sites in a commercial network (e.g. more than 12000 in UK for a single operator).
