Commonly used distance measurement methods include tape measure distance and photoelectric distance measurement. The measuring distance of a tape measure is measured along the ground using a tape-like ruler that can be rolled up, which is a direct measuring distance. Photoelectric ranging is to use an instrument to transmit and receive modulated light waves between two points, and measure the distance according to its propagation speed and time. It belongs to electronic physical ranging. Photoelectric ranging is indirect ranging.

In September, government agencies issued the radio frequency band to operators through auctions. It is expected that Indian telecom operators will provide 3G services early next year. However, this new requirement of the intelligence department may delay the launch plan of the operator's 3G service.
Indian-related security agencies, including intelligence agencies, have warned that they are currently unable to monitor certain services, such as Skype's Internet phone calls, Google Talk's chat service and even some video calls. If 3G services are introduced, users are likely to use mobile phones to bypass monitoring. In short, such as the launch of 3G services, intelligence agencies currently have no power to monitor any high-speed Internet applications based on this platform.
Currently, the monitoring device is only installed on the 2G platform, and similar services based on 2G can be monitored. All the private telecom operators in the country currently do not provide 3G services.
Last week, the security department instructed BSNL and MTNL to provide a legal interceptor for all 3G voice and data services within 15 days.
The latest order from the Interior Ministry of India to the Ministry of Telecommunications states: "Until the solution is in place, all telecom operators cannot provide 3G services, especially in Jammu and Kashmir (Jammu and Kashmir, border areas)."
On Tuesday, the Ministry of the Interior also convened a meeting of all operators providing BlackBerry services to solve the security problems of encrypted transmissions. The Ministry of the Interior has repeatedly warned BlackBerry maker RIM that its failure to provide mobile applications for surveillance will be banned.
RIM proposed a compromise last month that allows security agencies to track e-mails without sharing encryption details. The intelligence department is currently testing the feasibility of this program. If the program can allow the intelligence department to listen, then RIM's security problems can be solved. However, when the Indian government asked RIM to share the details of encrypted transmissions, it was rejected. RIM said that the company itself could not read the customer's encrypted information.
At the same time, the Indian intelligence department has asked the Ministry of Telecommunications to suspend Nokia’s popular information services in India until it can provide monitoring. From the perspective of security, related departments have already seen the security risks of these services.

The Indian intelligence agency hopes that all telecommunications operators in the country will ensure that all services based on this platform can be monitored, intercepted and locked before launching 3G services.
