Most of the outdoor 5G tests today use millimeter-wave frequencies, 28GHz and higher. Compared with today’s mobile networks, this technology uses pretty high frequencies because the already existing ones use 3GHz. Technologies with lower frequencies can have a bigger range, than those which use higher frequencies.
So what happens when we come to the point of 5G indoor connectivity?
The key to effective indoor mobile cellular coverage and capacity is a far traveling signal. Modern architecture can become a real problem when it comes to letting the radio signals to pass through them. It is hard enough for some of today’s licensed spectrum to get through building walls, and with 5G technology which uses short-range radio signals, it will be almost impossible.
5G will intensify in-building connectivity issues, impacting not just business within the buildings, but also CRE building and facilities managers who want to get top companies into their office space.
If they want to lessen this problem and improve indoor connectivity, design engineers can specify a full spectrum distributed antenna system network, which will be in the best position to support indoor 5G moving forward.
DAS is a kit of cabling, small remote units, and antennas that are distributed throughout a building and linked to a central distribution hub, which connects to the RF source used by the mobile operators. This only refers to indoor connectivity, with 5G there will be a separation in outdoor and indoor connectivity, unlike now where indoor network borrows signals from the outdoor network when necessary. Users will receive a guaranteed level of service.
Will this be the perfect solution for 5G technology indoor implementation, we will wait to see in 2020.
