RAS question
The V2V (Vehicle-to-Vehicle) communication technology announced for rollout by end-2026 uses which radio frequency band?
Correct answer: (B) 5.875-5.905 GHz.
The V2V vehicle-to-vehicle communication rollout announced for end-2026 uses the 5.875-5.905 GHz radio frequency band.
Explanation
V2V communication is tied to a dedicated spectrum allocation, not to ordinary mobile internet bands. The government is moving towards mandating vehicle-to-vehicle communication by the end of 2026, and the Department of Telecommunications has agreed in principle to earmark 30 megahertz in the 5.875-5.905 GHz band for these applications. The technology lets vehicles exchange data without requiring mobile internet. Its purpose is direct wireless exchange between nearby vehicles, including information such as location, speed and braking, so that real-time hazard warnings can be generated even when visibility or physical obstruction makes human detection difficult.
Why the other options are wrong
- (A) 2.4 GHz is not the dedicated V2V band for the end-2026 connected-vehicle framework.
- (C) 700 MHz is not the band identified by the Department of Telecommunications for these V2V applications.
- (D) 3.5 GHz is not the earmarked spectrum range for the announced vehicle-to-vehicle communication rollout.
Concept
This tests spectrum allocation for an emerging road-safety technology, a standard Science and Technology current-affairs theme in RAS. It recurs because such questions link telecom regulation, connected mobility and public-safety applications.
