Are You Ready for Next-Generation Mobile Network?
Finally, the most-awaited 5th Generation (5G) technology for mobile broadband has become a reality. Different countries including the United States (US), South Africa, South Korea, and China have started to rolling out fixed 5G in specific cities around their country. While other countries like Sweden, Turkey, and Estonia have also taken significant steps to provide a 5G network to their citizens.
Many telecommunication companies including Vodacom, MTN South Africa, AT&T Inc., Sprint Corp. (S), Verizon Communications Inc. (VZ), T-Mobile US Inc. (TMUS), KT Corp, Telefonaktiebolaget LM Ericsson (ERIC), and China Mobile are actively developing, testing, and deploying 5G networks in the selected cities.
In South Africa, Vodacom has launched 5G services in three major cities including Johannesburg, Cape Town, and Pretoria. They have initially deployed 20 live sites in the cities for the 5G network. Besides this, MTN has announced to deploy 100 5G sites covering areas of Johannesburg, Cape Town, Bloemfontein, and Port Elizabeth. While a much more comprehensive roll-out is expected in the next few years.
However, many people are still wondering if it’s worth upgrading to 5G compared to the currently deployed 4G LTE technology (Checkout our article here on Data Connectivity).
5th Generation Mobile Network is a new global wireless broadband standard after 1G, 2G, 3G, and 4G networks (See Article Here for more). It’s designed to connect every individual and everything together including smart devices, objects, and machines around the globe.
What 5G will offer?
The 5G wireless technology is meant to deliver multi-Gbps data speeds with higher performance, ultra-low latency (explained below), increased efficiency, massive network coverage, more reliability, and a more uniform user experience to more users.
This next-generation mobile broadband has been designed to eventually replace or enhance the existing 4G LTE technology to provide exponentially faster download and upload speeds. Moreover, 5G will also drastically reduce the latency of most devices i.e. the time they take to communicate with wireless networks.
What’s the Underlying Technology in 5G? (technical details)
5G is based on OFDM (Orthogonal Frequency Division Multiplexing) in which a digital signal is modulated across several different channels to reduce interference. It uses 5G NR (New Radio) air interface alongside OFDM principles to provide faster and better mobile broadband services.
5G or 4G | which is better?
There are several reasons that make 5G much better than 4G. One of the reasons is that 5G is designed to support new services that were not present in 4G technology e.g. mission-critical communications and device-to-device interconnection.
In terms of speed 5G can significantly provide up to 20 Gbps peak data rates and 100+ Mbps average data rates. This means that 5G can supports 100 times increase in traffic capacity and network efficiency compared to 4G.

In mobile networks, latency is the time a network takes to transmit some data and deliver it to its destination. It is also known as the round-trip delay measured in milliseconds (ms). As the latency of the network reduces, its performance gets better.
OFDM can transmit multiple carrier signals at a time such that there’s no interference.
5G NR is the global standard for a unified and more capable air interface for a 5G wireless network. It’s responsible for delivering significantly faster and more responsive mobile broadband experiences.
