Like many others we are also thinking what is 5G? How will it work? This article briefly skims through the important aspects of it. 5 G is the 5th generation in the cellular world, we will be able to send and receive the information less than one-thousandth of a second. That’s very quick though! It is 10-100 faster than the 4G we are current using provided by our cellular companies. The expected downloads will be in gigabits per seconds. A long movie of your choice will take only few seconds to download. Due to increase in cellular traffic and more number of users the companies have to look for ways for new technology and new infrastructure. The concept of millimetre waves is a new term. The waves will be 10-100 times higher than the radio frequency waves we are using in 4 G and Wi-Fi services. This will require more base stations.
