5G and Its Impact on Network Topology

By CIOReview | Thursday, November 15, 2018

5G is no longer just an idea; it has come to the fore with improved performances. 5G promises a lot of new services like a new and broad spectrum, more bandwidth, Ultra-reliable Low Latency Communications, lower cost per bit, higher efficiency, architectural enhancements, etc. Mobile operators have vowed to implement 5G and started to ship 5G enabled devices. 5G takes a cloud-to-user approach and unifies multivendor solutions into single standard based architecture. IoT devices have increased many folds, and it is expected to grow more in the coming years. With the boom in IoT devices, network operators are under pressure to deliver a quality network with enhanced performance and better security.

The 5G network will significantly boost mobile edge computing. The presently available cloud computing provides centralized storage, so the data has to be computed from the centralized storage only. 5G will provide decentralized computing which will enable computing of the data at the device only. This is gathering wider recognition because of its performance, security and artificial intelligence. The data and its processing will move closer to the user than the cloud as companies want local performance without depending on the cloud.

The enhanced features of 5G are discussed below:

Enhanced Mobile Broadband: 5G’s enhanced mobile broadband (eMBB) provides high speed and dense bandwidth to the users. With speed in gigabits, 5G provides an alternative to the traditional fixed line services.

Low latency communications: low latency communications feature of 5G provides transmission of high volume of data with minimum delay. This feature will be able to help in critical services like augmented and virtual reality, remote surgery, self-driving cars, and industrial automation.

Network Slicing: network slicing allows the network to be segmented according to a user’s need or a business’s requirement. The operator will define the granularity of a network to meet a business requirement.

Internet of Things: IoT devices are connected to sensors which require very low bandwidth and to cars also along with many other devices which require the bandwidth of a mobile device. The network slicing feature provides flexibility to businesses to manage their own devices and services on the network.

5G services are about redefining services and enhancing performance to best suit a user. It brings the data closer to the user than the cloud.
