Not only is the volume of mobile data traffic continuously rising, but it is set to skyrocket over the next 3-5 years with the advent of 5G, putting mobile network operators under CAPEX pressure.
Higher frequency bands for 5G mean more challenges for ensuring coverage, especially in dense urban areas where capacity will be needed but where stringent EMF limits apply.
While small cells are a good solution for improving capacity, they have many drawbacks:
Integrates seamlessly into the surrounding environment. Can be fitted to any window or wall.
Antennas at lower heights enable better network densification in dense urban areas.
Low power usage means lower EMF levels.
Fibre and power come from inside the building. No need to bring fibre and power outdoors.
Indoor installation means no scaffolding or permits needed.
Simpler electronics and smaller, lighter enclosures (IP44).
