What are the disadvantages of millimeter wave?

More than coverage or connected time, 5G mmWave should be measured by its ability to reduce the growing data strain placed on cellular networks . 5G mmWave is a revolutionary cellular technology, providing access to massive bandwidth and capacity available in frequency bands above 24 GHz.

Disadvantages of 5G mm wave Millimeter wave goes through different losses such as penetration, rain attenuation etc. This limits distance coverage requirement of mm wave in 5G based cellular mobile deployment. Moreover path loss at mm is proportional to square of the frequency.24 Kas 2019

Disadvantages of Millimeter Wave

The main disadvantage of 5G is that it has limited global coverage and is available only in specific locations . Only cities can benefit a lot from 5G network and remote areas may not get the coverage it for some years. Moreover, the expenses for setting tower stations are high when compared to other networks.

5G mmWave signals more likely to be blocked by physical barriers such as walls, buildings, and trees because its signals are transmitted at higher frequencies (option D). This can be explained in the following way: Lower frequency bands cover a longer distance but have a slower data rate.

mmWave doesn’t go far enough for good coverage Base stations will likely offer up to a kilometer of directed coverage , although 500 meters (~1,500 feet) is probably a safer bet, after taking into account obstacles and foliage.
