what is a limitation of 5g mmwave, despite its high speed?

That means 5G may not project over long distances. Smaller frequencies also don’t penetrate obstacles very well, so everything from concrete walls to tree leaves may disrupt signals . That makes it a line-of-sight technology – your wireless modem or phone will need to be close to a base station for best transfer speeds.

5G Tower Range In general, the 5G Ultra Wideband network’s signal can reach up to 1,500 feet without obstructions. Verizon is leveraging small cell technology to help deliver more 5G signal which directly increases the coverage and speed of the network.

5G wavelengths have a range of about 1,000 feet , not even 2% of 4G’s range. So to ensure a reliable 5G signal, there needs to be a lot of 5G cell towers and antennas everywhere.16 Eki 2020

5 GHz networks do not penetrate solid objects such as walls nearly as well as do 2.4 GHz signals . This can limit an access points reach inside buildings like homes and offices where many walls may come between a wireless antenna and the user.
