Hello all,
I recently started learning about 5G and would like to share my understandings as I continue to learn new concepts. This is my first blog post. So, please don't mind if there are some spelling/grammatical mistakes. Please do let me know in comments if you have a question/comments on my understanding.
What is 5G?
First we should ask the question "what is 5G?". As you may be aware, the International Telecommunication Union (ITU) lays out the requirements for every cellular generation. As for 4G, the requirement has been to support 1Gbps data throughput. Till 4G, the focus of cellular requirements were tied to only data throughput. But for 5G time frame, new industries & use cases emerged which demand for higher data throughput as well as improvements in other parameters. On one side, 5G is expected to support high data throughput and on the other side, it is expected to support billions of delay tolerant & low data throughput IoT devices. And then there are applications which need the data transfer to be with ultra-reliability with ultra-low-latency during ultra-mobility. Any technology that can be said as 5G needs to support all these use cases. Please note that, we'll only be discussing 5G developments by 3GPP in this blog.
As we discussed, 5G needs to support versatile use cases that will be deployed in a number of ways. 3GPP divided these developments in three folds and calls it NR*. Following is the pictorial representation of these requirements taken from Qualcomm's whitepaper. If you want to go through it in full, visit this.
*Why the name NR? - I think, just like for 4G, 3GPP came up with the name LTE as way of evolution to reach 4G standard. For 5G, the term NR is introduced which is abbreviated as "New Radio".
Deployment options of 5G:
Like the earlier cellular generations, 5G cant be deployed just like that considering its complexity and cost involved. So, 3GPP provided two deployment options for 5G. They are called NSA (non-standalone mode) and SA(standalone mode). In NSA mode, LTE/NR acts as an anchor carrier for dual connectivity mode and connects to EPC or 5G core network. In SA mode, NR is the only carrier and 5GC/EPC as the core network. Operator are expected to first start with NSA mode and then slowly move to SA mode .Each deployment type has different options which operators are free to choose from.
That is it for today for introduction. Will try to add new articles soon.
