'No need for cell towers': China has revolutionised smartphone communications

“不需要手机信号塔”：中国已经彻底改变了智能手机通信

NEW DELHI: In a landmark achievement for satellite communications, Chinese scientists have developed the world's first satellite capable of enabling smartphone calls directly, without the need for ground-based infrastructure. Named "Tiantong," which translates to "connecting with heaven," the initiative draws inspiration from the biblical story of the Tower of Babel, aiming to bridge communication gaps rather than create them.

中国科学家研发出了世界上第一颗不需要地面基础设施就能直接使智能手机通话的卫星，这是卫星通信领域的一项里程碑式成就。这项名为“天通”的计划的灵感来自圣经中巴别塔的故事，旨在弥合沟通上的鸿沟，而不是制造隔阂。

The Tiantong-1 satellite series, which began with its first launch on August 6, 2016, now includes three satellites in a geosynchronous orbit at 36,000km, covering the entire Asia-Pacific region.

“天通一号”卫星系列于2016年8月6日首次发射，目前包括三颗位于36000公里地球同步轨道上的卫星，覆盖整个亚太地区。

This breakthrough came to fruition when Huawei Technologies released the world’s first smartphone supporting satellite calls in September of the previous year, leading the way for other manufacturers like iaomi, Honor, and Oppo to follow suit, a South China Morning Post report said.

《南华早报》的一篇报道称，去年9月，华为发布了全球首款支持卫星通话的智能手机，引领小米、荣耀和Oppo等其他制造商纷纷效仿，这一突破取得了成果。

These technological advancements have proven invaluable, particularly in emergency situations where traditional communication networks are compromised. For instance, during the 6.2-magnitude earthquake in Gansu province on December 18, affected individuals could maintain contact with the outside world thanks to the satellite call function available on their smartphones.

事实证明，这些技术进步是无价的，特别是在传统通信网络受到破坏的紧急情况下。例如，在12月18日甘肃省6.2级地震期间，受地震影响的个人可以通过智能手机上的卫星通话功能与外界保持联系。

“Direct satellite connectivity for mobile phones has become a new development trend, and satellite communication will gradually become popular among the general public,” noted a team led by Cui Wanzhao from the China Academy of Space Technology. Their work, detailed in the Aerospace Science and Technology journal, highlights the overcoming of significant technical challenges related to passive intermodulation (PIM), which can degrade the quality of satellite calls.

中国空间技术研究院崔万钊领导的研究小组指出：“手机卫星直接连接已经成为一种新的发展趋势，卫星通信将逐渐在公众中普及。”《航空航天科学与技术》杂志详细介绍了他们的工作，强调了他们克服了与无源互调(PIM)相关的重大技术挑战，PIM会降低卫星通话的质量。

apple phones in US already work with Elon Musk 's satellites without any change in hardware. Congratulations China for successfully stealing another technology from the US.

美国的苹果手机已经可以在硬件没有任何改变的情况下用埃隆·马斯克的卫星打电话。祝贺中国又成功从美国窃取了一项技术。

This technology has been here for decades! Were just used for military and security purposes and not in mass scale. They have just put satellites in orbit for mass use now. So what's the big deal here?? Is this innovation? I don't think so...

这项技术已经存在几十年了，只是用于军事和安全目的，而不是大规模使用。他们刚刚把卫星送入轨道，以供大规模使用。这有什么大不了的？这是创新吗？我不认为是。

What the bid deal! We have invented phones that run just by chanting mantras into them…Jai Sri Ram Jai Sri Ram, Jai Sri Adani Jai Sri Adani, Jai Sri Ambani Jai Sri Ambani.

有什么大不了的！我们发明了只要对着念诵咒语就能运行的手机，

Meanwhile in India, they are still pop on railway tracks

与此同时，在印度，人们仍在铁轨上排便

Companies who have already invested 1000s of Crores on telecom towers in India will not allow this technology to take hold in India .

已经在印度电信塔上投资了10亿卢比的公司不会允许这项技术在印度扎根。

China is always ahead of others no matter what. These are few inventions that are made public. There could many that are kept secret.

无论如何，中国总是走在别人前面。这些是少数被公开的发明，有很多是保密的。

We invented "Zero" , it is base of this technology.

我们发明了“零”，它是这项技术的基础。

For andh-bhakts , "this technology was already in India during the Vedic period. We just need to download it from somewhere".

对于印度教信徒来说，“这项技术在吠陀时期就印度就有了。我们只需要从某个地方下载就行。”

For Pappu bhakht, India never has any technology , only pappu and Pakistan has high level technological knowledge.

对于拉胡尔的追随者来说，印度从来没有任何技术，只有拉胡尔和巴基斯坦有高水平的技术知识。

what is this nonsense technology, we have known distance between sun n earth , We know black holes , we know gravity , we knew zero which is base of this technology.

这是什么垃圾技术，我们知道太阳和地球之间的距离，我们知道黑洞，我们知道重力，我们知道零，这是这项技术的基础。

China is already a developed country now in league with US, Canada & Wetern Europe, Austrlia/Nzl. Just go and check their infrastructure how it had developed in last 20 years.

中国现在已经是发达国家了，和美国、加拿大、西欧、澳大利亚/新西兰属于同一个俱乐部。去看看在过去20年里他们是如何建设基础设施的。

Modi's revolution to put all oppositions in Jail and fight election alone without any opposition party..

莫迪的变革是把所有反对派都关进监狱，在没有任何反对党的情况下独自参加选举。

Vashisht

What is the big deal ? This has already been invented by our ancient Vedic maharishis 1000s of yrs ago . Detailed blueprint & technical specifications for all latest technologies is already available in our ancient Vedas & Upanishads. Other countries are merely copying from us .

这有什么大不了的？我们古老的吠陀大师在1000年前就发明了这种技术。所有最新技术的详细蓝图和技术规格都可以在我们古老的吠陀经和奥义书中找到。其他国家只是在抄袭我们。

Sambit

Weren't sat-phones already in use? Not clear from the article, what the innovation was? Did they reduce antenna size?

卫星电话不是已经在用了吗？从文章中看不明白，创新是什么？他们减小了天线的尺寸吗?

This is not a new technology. Elon Musk's Starlink already started doing it several years back. It was always known that the Chinese copied Musk's techonlogy. Now its openly tauted by the chinese copy masters.

这不是一项新技术。埃隆·马斯克的星链早在几年前就已经开始这样做了。众所周知，中国人抄袭了马斯克的技术。现在他们被嘲笑为：山寨大师。

china is china far superior to india in everything. india is 1 million years back of china. what a shame.

中国在各方面都比印度优越得多。印度比中国落后100万年。真丢人。
