5G networks promise higher speeds and lower latency compared to existing cellular networks. However, 5G signals are more easily obstructed since their wavelengths are shorter. Carriers are still learning how 5G will perform in different environments. Issues include signal obstruction by trees and effects of weather. More real-world data is needed to develop 5G properly. Applications of 5G include high-speed file sharing and downloads, streaming, and IoT uses like monitoring. Major players developing 5G include Samsung, Qualcomm, Nokia, and Huawei. Canada is conducting 5G trials and is positioned well for national 5G deployment.
