Perhaps it is not the most-common challenge one will hear about edge computing, but the availability of three-phase power is an issue for edge computing, albeit an issue firms such as Schneider Electric are solving.
Schneider Electric’s Edge Module includes single- or three-phase power, N+1 standard cooling, and package cooling units mounted on the outside of the module to eliminate the need for external condensers or piping, the company notes.
The Edge Module is specifically suited to the cell tower edge with its single-phase design equipped for 208 volts of power and supporting six racks.
The issue is that server farms are expected to require access to high-voltage, three-phase electricity, and cannot use 120 volt AC, which is single phase. Three-phase is used by electrical transmission facilities and supports heavy power loads for big motors, for example.
The issue is that cell towers have not generally had access to three-phase power, as it was not needed. The typical base station requiring less than 10kW will only be using single-phase power, experts tend to agree. Three-phase power would be used at power levels of 20kVA of alternating current and above, which will tend to be the case for server farms, experts also tend to agree.
