Mr. Patrick Neary:

I will correct the Chairman. Basically, the higher frequencies find it more difficult to get through walls and insulation. The lower frequencies penetrate walls more easily. Sticking to 5G, the frequency that was released in 2017 is 3.5 GHz. That is quite a high frequency. It is probably medium. That would struggle somewhat to get through walls but the 5G frequency that is going to be released next year is 700 MHz. That would penetrate walls a bit better. Ultimately, however, once the frequency hits a second wall it starts to diminish anyway. Wi-Fi calling will have a big impact once there is a Wi-Fi service. The NBP will have a big impact on how reliable the Wi-Fi service will be in rural areas. Once people have the Wi-Fi in place, they will be able to make high-quality calls. In the immediate term, there is the repeater, a solution that was brought into play last year.

The other aspect of 5G is that there is a native voice service available on it. A voice over IP service is available on 5G. It is not available today on 4G. That means that one needs 2G or 3G coverage to make a voice call today, which really means that the 4G coverage is not very useful for voice.
