Carbajo Martin believes that 5G can fulfill the promise to quickly and easily get fixed wireless access (FWA) into the home of customers interested in fast internet via Fixed Wireless Access (FWA).

Many promises were not kept

The promise of mobile "wireless" Internet access has already been made several times. The technology just wasn't powerful enough back then. And every provider of FWA has to be prepared for full competition from all forms of fast copper lines such as VDSL, SVDSL or G.fast and, above all, real glass fiber (FTTH / FTTB).

Telefónica Deutschland, reported Carbajo Martin, is already trying out this technology in Hamburg on 26 GHz. The technology supplier there is Samsung and the tests are soon to be transferred to a commercial status and accessible to a larger group of customers.

Test for yourself what is possible and what the market accepts

"On the one hand, we want to test the technology, but of course we also want to see whether the market accepts it and what customers think of this type of technology." There have been tests with this technology in other parts of the world, but they may be Conditions and circumstances here in Germany are different. That's why we wanted to try it out ourselves. "

Breakthrough at FWA?

Germany could be an interesting market for FWA offers. In the metropolitan areas, many people live in a small area and there is often little fiber optic. The large tenement houses are often "awarded" to certain cable TV operators via the "ancillary cost privilege", and the residents hardly have any alternatives. On 26 GHz o2 could come into the houses without having to ask the property management.

Telefónica wants to have its pilot tests ready by the beginning of 2019 before a decision is made as to whether the technology will be "rolled out" on a large scale.

Why it should work now (and has not worked so far) is actually obvious to Carbajo Martin: Only 5G technology offers the bandwidths and capacities that the customer expects.

"There are predictions that we will have to massively build 5G in 2022 or 2023 in order to be able to meet customer capacity needs, if we look at the current data growth. And it stands to reason that the rapid data growth will continue or increase even further.

We'll have to build it up

But Carbajo Martin is also honest: You can't build it today, but soon. The demand for mobile broadband connections is big enough that O2 has to build it up. The cell phone operators are doomed to succeed.
