电信公司在沟通点和DGCA之间的差距
电信部门,在11月下旬公报,指示电信公司禁用5 g基站在3.3 -3.6 GHz乐队,或mid-band,大约2公里内的两端跑道,几乎一公里从印度机场的跑道的中线。
孟买|新德里:电信服务提供商似乎陷入了通信之间的差距电信部(点)和民用航空总局(DGCA)提供5克服务在机场。没有迫在眉睫的决议,点强制禁用5 g基站周围的机场是拿走一块优质用户的潜在目标依赖Jio和Bharti Airtel5 g升级,说行业高管。
电信部门,在11月下旬公报,指示电信公司禁用5 g基站在3.3 -3.6 GHz乐队,或mid-band,大约2公里内的两端跑道,几乎一公里从印度机场的跑道的中线。
DGCA民航监管机构,然而,说它不想5 g基站关闭,并没有提及任何具体服务机场周围地区通信发送到电信部门。
“我们没有禁止5克机场附近,但要求他们只在低功率运行,限于58 dBm的乐队,“DGCA一位高级官员说,要求不透露姓名。德里、孟买和班加罗尔机场航站楼运行5 g协议下,他补充说。
DBm代表分贝毫瓦和是一个单元来表示信号强度在广播、微波和光纤网络。dBm值越接近于零,信号强度越强。
与此同时,Jio和附近的旅馆——两家电信公司在中国推出了5 g服务从10月——关闭的过程中他们mid-band 5 g基站附近的机场,按照点授权。
电信高管表示,这是导致中断5 g的采用,因为它本质上疏远了机场周围地区的消费者从升级到5 g网络的机会。
现有消费者,所面临的挑战,提出了所谓的“5 g黑暗”在机场,航空公司说,这可能会导致连接问题。
“这(点指令)似乎是一个下意识的反应,需要适当的研究。如果DGCA没有要求关闭基站,然后点电信公司的指示是不必要的,特别是因为它是早些时候保证5 g频率不会干扰航空频率,”一位高管表示,两家电信公司之一。
所代表的公司,印度手机运营商协会(COAI)上个月曾写信给点,认为他们的情况下保持基站。根据电信公司,飞机高度计系统上运行c波段电波从4.2 Ghz以上,而不是3.30 - -3.67 Ghz频段被用于5 g服务在印度,从而抵消干扰的恐惧。
然而,没有回应COAI的信,有过任何会议呼吁的问题。
两家电信公司和点没有回复等的邮件查询。
从长远来看,点要求会阻碍消费者和企业使用的部署情况下,运营商的恐惧。
DGCA同时给航空公司直到2023年底取代高度计,不能过滤掉细胞传输频率以外的各项规定,DGCA官员说。
“然而,这取决于飞机制造商也有一个全球供应链问题,”这位官员说。
高度计在4.2 - -4.4 GHz的频率范围,经营全球实践。
未来12 - 18个月是至关重要的电信运营商,他们试着推动5 g采用消费者。通常,周边地区机场在德里和孟买等城市覆盖大量的住宅和商业高端手机用户地址和房子。这些用户是在100 - 150 5 g用户Jio和旅馆都是针对推动5 g采用通过更好的覆盖范围和速度,无限数据津贴和身临其境的消费者用例。

“波段间频谱共享可能发现许多接受者”
他们补充说,波段间光谱的基本原理和活跃的基础设施共享在短期内还不存在两大电信公司,依赖Jio和Bharti Airtel5 g,追求截然不同的策略。这是自Jio选择了独立(SA)模式为其全国5 g网络推广而Airtel选择了non-standalone (NSA)模式,有非常不同的全球生态系统。

Mumbai | New Delhi: Telecom service providers appear to be caught in a communication gap between the Department of Telecommunications<\/a> (DoT) and the Directorate General of Civil Aviation<\/a> (DGCA<\/a>) on providing 5G<\/a> services around airports. With no imminent resolution, the DoT mandate on disabling 5G base stations around airports is taking away a chunk of premium users who would have been potential targets of Reliance Jio<\/a> and Bharti Airtel<\/a> for a 5G upgrade, say industry<\/a> executives.
The telecom department, in a late November communique, instructed telcos to disable 5G base stations in the 3.3-3.6 GHz band, or the mid-band, within about 2 kilometres from both ends of the runway and almost a kilometre from the centre line of the runway of Indian airports.
The civil aviation regulator, DGCA, however, says it didn\u2019t want the 5G base stations shut off, and that there was no mention of any specific service area around airports in a communication it had sent to the telecom ministry.

The civil aviation regulator, DGCA, however, says it didn\u2019t want the 5G base stations shut off, and that there was no mention of any specific service area around airports in a communication it had sent to the telecom ministry.
<\/div><\/div>\"We have not forbidden 5G near airport but have asked them to operate only at lower power, limited to 58 dBm of the same band,\" said a senior DGCA official, asking not to be named. Delhi, Mumbai and Bengaluru airport terminals are operating 5G under the protocol, he added.
DBm stands for decibel milliwatts and is a unit to represent signal strength in radio, microwave and fibre-optic networks. The closer the dBm value is to zero, the stronger the signal strength.
In the meantime, Jio<\/a> and Airtel<\/a> \u2013 the two telcos to have launched 5G services in the country from October - are in the process of turning off their mid-band 5G base stations near airports, as per the DoT mandate.
This, telecom executives say, is resulting in disruptions of 5G adoption as it essentially alienates consumers in the area around airports from the opportunity to upgrade to 5G networks.
For existing consumers too, it poses the challenge of the so-called \u20185G darkness\u2019 around airports, which may result in connectivity issues, carriers say.
\u201cThis (DoT directive) seems like a knee-jerk reaction to something that requires proper research. If the DGCA has not asked to turn off base stations, then DoT\u2019s instructions to telcos is unnecessary, especially since it was earlier assured that 5G frequencies will not interfere with aviation frequencies,\u201d said a senior executive at one of the two telcos.

<\/div><\/div>The companies, represented by the Cellular Operators Association of India (COAI), had written to DoT last month, arguing their case to keep the base stations on. According to telcos, aircraft altimeter systems run on C-band airwaves from 4.2 Ghz and above, and not 3.30-3.67 Ghz spectrum that is being used for 5G services in India, thus negating the fears of interference.
However, there has been no response to COAI\u2019s letter, neither has there been any meetings called on the issue.
