India has concluded the auction of its 5G spectrum with the sale of airwaves worth Rs 1,50,173 crore. The release of 5G services in India is imminent, so we have compiled some pretty helpful resources for you. You can check the list of supported 5G bands in India along with the instructions to find 5G bands supported on your phone. In case you are in a dilemma, you can also check whether you need a new SIM card for 5G services. Coming to 5G development in India, the TSDSI (Telecommunications Standards Development Society, India) has designed an indigenous 5Gi standard, which is creating quite the buzz. But what exactly is 5Gi and how it’s different from the global 5G standard? To find answers to these questions, let’s first understand what is India’s 5Gi standard.
In this article, we have discussed 5Gi in India’s context, compared 5G and 5Gi, and explained the issues with its deployment. Expand the table below and learn everything about India’s indigenous 5G standard right here.

What is the 5Gi Standard?
5Gi is a local 5G standard developed by India, thanks to a joint collaboration between IIT Madras, IIT Hyderabad, TSDSI, and the Centre of Excellence in Wireless Technology (CEWiT). The homegrown 5Gi standard (also known as Radio Interface Technology or RIT) is aimed at improving 5G coverage in rural and remote areas of India’s diverse geographical terrain.
In December 2021, the ITU (International Telecommunication Union) approved the 5Gi standard and agreed to merge its specifications with 5G’s standard under a compromised formula. This is a huge win for India as 3GPP rarely approves competing standards to maintain global interoperability. But how does 5Gi differ from 5G, and what are the challenges in deploying 5Gi? To learn more, move to the next section.
What’s the Difference Between 5Gi and Global 5G: 5Gi vs 5G:?
In comparison to the global 5G standard, the 5Gi standard uses Low Mobility Large Cell (LMLC) to extend 5G connectivity and the range of a base station. It does so by using bands of the spectrum, which are lower than 5G’s operational bands but offers a high-range waveform. Ideally, the 5G frequency band ranges from 700MHz to 52GHz, but 5Gi can go lower than 700MHz and up to 36GHz without sacrificing the range.

There are two major benefits of using the 5Gi standard, especially in India. Let’s look at them in detail right here:
What are the Issues with 5Gi?
While TSDSI claims that 5Gi will reduce deployment costs and improve coverage, telecom partners in India are not entirely enamored by the indigenous technology. The telcos say that maintaining interoperability between 5Gi and 5G’s global standards will make things even more expensive. It will require further changes in hardware, and India’s cash-strapped telcos are not in a position to bear the brunt of additional compatibility. Even telecom vendors like Nokia, Ericsson, Huawei, etc. have shown reservations in supporting 5Gi.
Some experts believe that existing 5G phones, which have been released as per the 5G specifications, may become incompatible with 5Gi’s frequency bands. The COAI (Cellular Operators Association of India), which counts telecom companies like Airtel, Jio, and Vi as members, has asked the government to make 5Gi a discretionary standard rather than a mandatory one.
As far as mobile communication is concerned, interoperability is something everyone seeks for global compatibility with various handsets and service providers. In this regard, adopting a local 5Gi standard over the global, more compatible 5G standard would make things worse for all parties — starting from telecom vendors, cellular service providers to smartphone makers and finally, consumers. In fact, even Reliance Jio says that it supports local standards, but it should be in line with the global standard for ensuring compatibility.
Frequently Asked Questions
Will my 5G phone support India’s 5Gi network?
