On July 9, a technical working group of the International Telecommunication Union<\/a> (ITU) approved an application for recognition of the 5G Radio Interface Technology<\/a> (RIT) submitted by Telecom Standards Development Society, India (TSDSI<\/a>) as a candidate 5G standard, along with the RIT submitted by 3GPP. TSDSI<\/a> is an autonomous Indian standards setting body, comprising industry and academia recognised by the DoT.
The highlight of the TSDSI RIT is that it improves upon the 3GPP RIT to bridge the digital divide<\/a>, by providing enhanced performance for ITU’s Low Mobility Large Cell (LMLC) rural use case. This enhanced RIT incorporating patented innovations of Indian researchers is otherwise fully compatible with the 3GPP RIT in every respect. India’s relatively late but vital contribution towards under-served populations has cleared hurdles to acceptance as a global 5G standard.
The TSDSI RIT is designed to make 5G technology work well in rural areas with low-speed mobility and large cells of up to 6 km radius. It primarily seeks to bridge the digital divide<\/a> by enabling affordable 5G broadband through indigenous technology, leveraging India’s rural optical fibre network BharatNet<\/a>. This brings 95% of India’s villages into the coverage regions of base stations deployed at gram panchayats (GPs) served by BharatNet<\/a>. The LMLC requirement mandated by ITU is only a 3 km coverage radius, insufficient for India’s rural areas and those of many other countries. The higher coverage is achieved with minimal but innovative enhancements to the 3GPP specifications, at negligible additional cost.
TSDSI initially approached 3GPP with its proposals, but found opposition in global telecom majors for varying reasons including paucity of global interest in enhanced rural coverage of the kind required in India. Despite persistent pressure from Indian entities, only a poor subset of its proposals was incorporated into their specifications merely as an optional feature, leaving over 33% of India’s villages unreachable from towers located at the GPs. Dissatisfied, the TSDSI working groups focussed on re-incorporating the necessary technology enhancements that would work seamlessly with the specifications developed by 3GPP, instead of simply settling for the best rural fit from what is available on the global shelf.
Indigenous technology development in India often encounters scepticism about our technical capacity and lack of global scale and volume. TSDSI’s efforts are no exception. There have been concerns around India’s “unilateral” standard setting degrading interoperability with the global 3GPP standard, undermining consumer choice, delaying rollout of 5G in India and increasing cost due to the two technology variants demanding separate hardware. Inclusive stakeholder consultations have been advocated, to avoid a “fragmented” 5G technology isolating India from global value chains.
These concerns do not account for TSDSI’s collegial pursuit of solutions relevant to India’s needs in harmony with global standards. We should not get diverted by specious arguments from those that may benefit from India not having its 5G technology variant.
The familiarity of all major telecom manufacturers with the technical specifications made by TSDSI should enable quick development of solutions, ensuring total interoperability between equipment conforming to both TSDSI and 3GPP RITs at negligible extra cost as it only requires a modest one-time software\/ firmware change in the base station and the handset. The indigenous TSDSI 5G standard would also provide opportunities for Indian companies to design innovative solutions for extended 5G applications not only for India but also for the world.
The TSDSI 5G RIT has been through rigorous domestic and international evaluation processes, and meets a critical Indian need without compromising global interoperability or adding cost. It will fulfil the unmet need of unconnected people in India and other developing countries. It neither islands our market or country, nor takes it down a technology fork that arrests future evolution of wireless technologies in step with the rest of the world.
It is a well-formulated and harmonious response to the pressing developmental needs of a very large number of consumers, who unfortunately often escape global attention. Indeed, it is our fervent hope that, sooner rather than later, the enhancements proposed in the TSDSI RIT will get folded into the 3GPP RIT (as originally intended by India) and a single global standard will address everyone’s needs, including those on the wrong side of the digital divide.

自主开发5 g技术如何实现远程印度村庄
TSDSI RIT旨在使5 g技术工作在农村地区低速流动和大细胞6公里的半径。它主要是寻求弥合数字鸿沟使负担得起的5 g宽带通过自主技术,利用印度的农村BharatNet光纤网络。
读到
7月9日,一个技术工作小组国际电信联盟(ITU)批准申请5 g的识别无线接口技术(RIT)提交的电信标准开发的社会,印度(TSDSI)作为候选人5 g标准以及3 gpp的RIT提交。TSDSI印度是一个自治的标准制定机构,包括工业和学术界认可的点。
TSDSI RIT最精彩的部分是,它改进了3 gpp RIT的桥梁数字鸿沟电联,通过提供增强性能的低流动性大细胞(LMLC)农村用例。这种增强RIT将印度专利创新的研究人员与3 gpp RIT否则完全兼容在各方面。印度人口相对较晚但至关重要的贡献供不应求的清除了障碍接受作为一个全球5 g标准。
TSDSI RIT旨在使5 g技术工作在农村地区低速流动和大细胞6公里的半径。它主要是寻求桥数字鸿沟通过使负担得起的5 g宽带通过自主技术,利用印度的农村光纤网络BharatNet。这让印度95%的村庄到基站的覆盖地区部署在克panchayats (GPs)服务BharatNet。LMLC要求由国际电信联盟只是一个3公里覆盖半径,不足为印度的农村地区和许多其他国家。较高的覆盖率达到以最小的但创新增强3 gpp规范,在额外的成本可以忽略不计。
TSDSI最初接近3 gpp的提案,但发现反对全球不同的原因包括缺乏全球电信专业兴趣增强在印度农村覆盖率的要求。尽管印度实体持续的压力,只有一个可怜的子集的提议被纳入他们的规范只是作为一个可选的特性,把超过33%的印度村庄从塔位于GPs遥不可及的。不满,TSDSI工作组关注re-incorporating必要的技术改进,与规范由3 gpp无缝地工作,而不是简单地解决最好的农村适合从全球货架上可用。
自主技术开发在印度经常遇到怀疑我们的技术能力和缺乏全球规模和体积。TSDSI的努力也不例外。有问题在印度的“单边”与全球3 gpp标准设置有辱人格的互操作性标准,削弱了消费者的选择,延迟推出5 g在印度和增加成本由于两种技术变体要求单独的硬件。包括利益相关者磋商一直主张,以避免“支离破碎”5 g技术隔离印度从全球价值链。
这些担忧不占TSDSI合议的追求与印度有关的解决方案需要在和谐与全球标准。我们不应该得到转移由那些似是而非的论点可能受益于印度没有5 g技术变体。
熟悉的所有主要电信制造商技术规范由TSDSI应该支持快速开发的解决方案,确保总设备之间的互操作性符合TSDSI和3 gpp研究院额外成本可以忽略不计,因为它只需要适度一次性软件/固件基站和手机的变化。土著TSDSI 5 g标准也将为印度公司提供机会为延长5 g应用程序设计创新的解决方案不仅对印度,也是世界的机遇。
TSDSI 5 g RIT已通过严格的国内和国际的评估过程,印度需要的前提下,满足一个关键的全球互操作性或增加成本。它将实现未满足的需求无关的人在印度和其他发展中国家。它无论是岛屿我们的市场或国家,还是把它缩小技术叉逮捕未来无线技术的进化与世界其他地区。
编制和和谐响应迫切的发展需求大量的消费者,谁不幸常常逃避全球关注。事实上,热切希望,迟早,TSDSI RIT的增强提出将并入3 gpp RIT(最初的印度)和一个全球标准将满足每个人的需求,包括那些在错误的一边的数字鸿沟。
