Jio Platforms (JPL) is Flaunting their 5G Wares

In the world where we talk about just two or three major mobile network infrastructure vendors, challengers are rising, either using Open RAN/Networks as their base, innovations as a leverage or the might of a huge population to ensure their network infrastructure has been tested in the most extreme of scenarios. Jio Platforms (JPL) is probably relying on all the three conditions listed above. 

Jio Platforms Ltd. is an Indian technology company and a subsidiary of Reliance Industries Limited, headquartered in Mumbai, India. Jio Platforms has an end to end 5G solution consisting of 5G Radio, a complete 5G Core Network, AI/ML ATOM platform for 4G/5G, MANO for cloud CNF orchestration, ACI for cloud infrastructure deployment as well as the Cloud-native OSS Platforms.

In addition to these core platforms, Jio Platforms has also created its own cloud-native probing solutions for radio and core networks, simplifying network debugging and not requiring any systems integration with probe providers. To enable a SaaS-based model, JPL has also developed a sophisticated array of BSS solutions.

The entire product line is cloud native and can be deployed either on a public cloud or a private cloud.

In the recently concluded MWC 2023, Jio Platforms sponsored quite a few tracks and spoke in some as well. Aayush Bhatnagar, SVP of Technology at Jio Platforms gave a fantastic presentation in the track, '5G Advanced, Ready for Take-Off!'. His talk is embedded below:

While Jio relied on Airspan (for small cells) and Samsung for 4G/LTE networks, for 5G Jio has partnered with Ericsson, Nokia, Samsung, Cisco, Microsoft, etc.

Ericsson's press release mentioned that it will supply: Ericsson’s energy-efficient 5G Radio Access Network (RAN) products and solutions (from the Ericsson Radio System portfolio) and E-band microwave mobile transport solutions will be deployed in the 5G network for Jio.

Nokia's press release mentioned that it will supply: Equipment from its AirScale portfolio, including base stations, high-capacity 5G Massive MIMO antennas, and Remote Radio Heads (RRH) to support different spectrum bands, and self-organizing network software.

Telecom TV has a good summary of Jio Platforms presentation from DTW2022 (a version of their presentation video is available here). The JPL speakers mentioned that the company always had in mind that it wouldn’t be developing platforms, cloud-native functions and applications just for itself – it always had the broader market within India, and beyond, in mind. This was the reason they adopted a platforms-as-products (PaPs) strategy to its R&D.

It's yet to be seen how equipment from JPL interworks with ones from Nokia, Ericsson and everyone else. Right now Reliance Jio is busy launching 5G in more and more cities. The speeds, quality of experience and reliability will be the judge of their network and and a catalyst for adoption of Jio Platforms.

5G to Help Greenland Connect Over Vast Distances

Greenland, an island of just 56,000 people, is part of the Kingdom of Denmark but has broad autonomy. Greenland has, by law, only one service provider for telecommunications and the Internet, TELE Greenland, which is fully owned by the Greenlandic Home Rule government. TELE Greenland provides switched telephone and data, land mobile communications, and VHF and MF shore-to-ship communication. This type of monopoly is not uncommon in Greenland.

The state-owned TELE Greenland A/S Group was the main telecommunication and postal provider in Greenland and its headquarters are in Nuuk. It also operated the only mobile network in the country. TELE Greenland A/S was rebranded as Tusass in 2021 and all phone and postal services are under the Tusass label now. Tusass is Greenlandic slang for "talk to you later".

2G and 3G is on 900 MHz, 4G has started 2013 in Nuuk on 800 MHz (band 20) and is in these towns in 2015: Nuuk, Qaqortoq, Ilulissat, Sisimiut, Maniitsoq, Aasiaat and airport Kangerlussusuaq. Every settlement with more than 70 inhabitants has at least 2G coverage, but most areas of the country are uninhabited. Detailed coverage maps you can find here. At the end of 2018 their 4G/LTE coverage has risen to 92% of the population.

Ericsson has been contracted by Tusass to build a 5G network in Greenland, initially covering three towns. A further 10 towns, including Greenland’s capital Nuuk, are set to follow next.

Deploying Ericsson equipment and Netgear routers, Tusass intends to bring high-speed wireless internet to the sparsely populated island without resorting to expensive and hard-to-deploy cables.Tusass says it plans to invest around 1 billion Danish crowns ($131.3 million) to secure and expand Greenland's infrastructure and improve communication.

According to Jenny Lindqvist, head of Northern and Central Europe, Ericsson, a 5G network will help those living in Greenland “connect over vast distances,” a necessity in a country considered to be the least densely populated territory in the world. Only 56,000 people live in Greenland’s 2.16 million square kilometers.

“From a broad perspective, this partnership serves the digitalization of Greenland, from enabling use cases for control of critical infrastructure and remote devices to bringing new entertainment services for the people,” Lindqvist said. “Regardless of how challenging the project is or extreme the weather conditions, Ericsson remains committed to create a wireless Greenland together with Tusass.” 

In December 2022 Tusass revealed that it is planning to shut down its 3G services in 2023, in line with global trends. Tusass said that it took the decision to discontinue the technology ‘because spare parts are no longer produced, because support services are no longer provided and new technologies surpass the efficiency and quality of the old ones’. The operator disclosed that it will notify customers at least three months before the fixed shutdown date.

Nepal is Taking Right Steps in Direction of 5G

Unfortunately Nepal's telecom sector has several topographical and economic constraints which have impeded efforts to expand network infrastructure and improve the quality of service for end-users.

The fixed line market remains underdeveloped, and as a result most traffic is channelled via mobile networks. Fixed broadband penetration remains very low, though to address this the government has initiated several programs as part of the Digital Nepal Framework and the wider Optical Fibre Backbone Network Expansion Project, started in 2012. Supported by the Rural Telecommunications Development Fund, the programs include building out fibre backbone infrastructure and using this to provide broadband to schools and community centres nationally.

Operators have also invested in fibre networks, and competition in the market is intensifying. Cheap fibre-based services launched by CG Net in mid-2021 prompted responses from other ISPs to provide faster and more competitively priced offers.

Nepal’s mobile market is relatively developed, with a focus on LTE. In 2021, the regulator considered a range of spectrum bands which could be used for 5G.

Nepal has three GSM mobile operators: Nepal Telecom (state owned), Ncell (owned by Axiata) and Smart Cell (by Smart Telecom, limited coverage on 2G, 4G/LTE; no 3G).

2G is on 900 and 1800 MHz and 3G on 2100 MHz. In 2016 the government of Nepal begun the process of converting existing wireless licences to technology neutral permits, enabling operators to use their current 900 MHz for 3G and free their 1800 MHz (B3) frequency holdings to offer 4G/LTE services. 4G/LTE has been launched by all three providers in 2017. Due to its mountainous territory, coverage can be very spotty and data speeds extremely slow outside the Kathmandu central valley or Pokhara.

Nepal Telecom (NTC) is the state owned, national provider in Nepal. It has a monopoly on landlines and broadband, but competes with Ncell for mobile customers. 

NTC uses 900 Mhz for 2G and 2100 Mhz for 3G. Simultaneously, it runs a CDMA network too which will be switched off by 2021. GSM-coverage is slightly lower than Ncell. Until 2017 only about 60 3G sites have been installed and on air including Banepa, Bhaktapur, total 59 sites in Kathmandu and 1 site in Pokhara.

4G/LTE has started as first provider in Nepal in 2017 on 1800 MHz (B3) only in the Kathmandu Valley and Pokhara only opened for prepaid. NTC signed 40,000 LTE users in two weeks alone. In 2019/20 the 4G network was expanded and it has 4G coverage at these locations.

Nepal Telecom has a total of 18.95 million mobile broadband users where 7.26 million are 3G users, 11.55 million are 4G users and 136,573 are EVDO users. Just last year Nepal Telecom (NT) marked its 18th anniversary by announcing the commercial launch of VoLTE services, enabling customers with a compatible handset to enjoy high definition voice calling over its 4G network and simultaneous use of voice and high speed data services.

Nepal Telecom had originally planned to kick off 5G trials in mid-July 2021, but the timetable was delayed after a change of government prevented assignment of the additional spectrum resources required. Having finally been granted a testing permit and 60MHz of frequencies in the 2600MHz band the following November, NT then encountered further problems with equipment delivery, while plans to finally start the trial last month were thwarted by the extremely low number of compatible devices. The operator intends to launch test networks in all seven provinces of the country by the end of its current financial year (mid-July 2023).

Ncell is the no.2 in Nepal with a total of 8.88 million mobile broadband users where 1.93 million are 3G users and 6.95 million are 4G users.

Its 2G is on 900 and 1800 Mhz and reaches 90% of population, 3G is on 2100 Mhz in about 20 of the biggest towns. Ncell Coverage Map. Ncell is the better provider in the country, but there are still many areas uncovered and don't expect high speeds.

The start of their 4G/LTE was further delayed in 2017 by taxation issues and was finally launched in June 2017 on 900 and 1800 MHz in the Kathmandu Valley, including the areas of Nagarkot, Banepa and Dhulikhel. In summer 2017 the cites of Biratnagar, Birtamode, Damak, Dharan, Bharatpur, Hetauda, Birjung, Bhairahawa, Butwal and Nepalgunj were added to the 4G/LTE network. In 2019 seven of the country’s provinces and over 1,000 locations nationwide are covered, making it Nepal’s most extensive 4G network.

In September 2022 they announced the commercial launch of their VoLTE service, providing customers with superior quality HD voice and faster call connectivity. The new service is activated free of charge and is currently available on selected Samsung, Vivo and Huawei handsets. Customers enabling the service will receive 100 bonus minutes of on-net talk time valid for 28 days. Launched in June 2017, Ncell’s LTE network has been expanded to areas of more than 70 districts and now covers approximately 85% of the country’s population.

Smart Telecom is the third telecom operator in the country, they only has 2G and 4G services in its Smart Cell brand. They have a total of 127,551 subscribers to their 4G service.

They are on 2G/GSM on 1800 MHz. In 2017 a license to use 4G/LTE was granted to Smart and in October 2017 Smart has finally launched its long-awaited 4G/LTE service, with the company stating that it is now live in Kathmandu, Lalitpur, Bhaktapur and Pokhara. The new 4G service offers customers speeds of up to 70 Mbps. Smart Telecom has been granted 10 MHz of frequencies in the 1800 MHz (B3), while its two competitors Nepal Telecom (NT) and Ncell have only been allocated 5 MHz each in this spectrum band.
