Direct-to-Device (D2D) Technologies

• The Department of Telecommunications (DoT) recently organized a high-level workshop through the Telecommunication Engineering Centre (TEC) to explore Direct-to-Device (D2D) satellite communication.

About Direct-to-Device (D2D) Technologies:

• Direct-to-Device (D2D) is an emerging satellite communication technology that allows standard, off-the-shelf mobile devices (like your smartphone) to connect directly to satellites without the need for specialized hardware, satellite phones, or intermediate ground equipment.
• It essentially turns satellites into cell towers in space, extending cellular coverage globally.

How it Works?

• Satellite Constellations: A network of Low Earth Orbit (LEO) satellites is deployed, equipped with large, powerful antennas capable of picking up low-power signals from standard phones.
• Spectrum Integration: These satellites use the same terrestrial LTE or 5G frequency bands that mobile operators already use on the ground.
• Seamless Handover: When a user moves out of the range of a traditional terrestrial cell tower, the phone automatically switches its connection to a passing satellite.
• Non-Terrestrial Network (NTN): The satellite acts as a relay, sending the signal to a ground station (gateway), which then connects to the core mobile network of the service provider.

Key Features:

• Standard Device Compatibility: Unlike traditional satellite telephony which requires bulky handsets with large antennas, D2D works with existing 4G and 5G smartphones.
• LEO Satellite Utilization: By using Low Earth Orbit satellites (500–2,000 km altitude), the latency (delay) is significantly reduced compared to traditional geostationary satellites.
• No Additional Infrastructure: It eliminates the need for expensive ground-based towers in geographically challenging terrains like mountains, deserts, or islands.
• Software-Defined Connectivity: Many D2D solutions are being integrated into the 3GPP (Global Telecom Standards) release 17 and 18, making it a globally standardized feature.
• Emergency SOS & Messaging: Early-stage D2D focuses on low-bandwidth services like emergency text alerts, though it is evolving toward full voice and data capabilities.

Significance:

• It provides a safety net of connectivity in areas where it is economically or physically impossible to build towers, ensuring 100% geographical coverage.
• In the event of an earthquake or flood that destroys ground-based infrastructure, D2D provides an indestructible communication link for rescue operations.

Scientists Develop New Method to Measure Distance in Deep Space

• Indian astronomers have developed a method to measure cosmic distances by studying how pulsars interact with the space they travel through.

About Pulsars

• Pulsars are highly magnetised, rapidly rotating neutron stars that emit beams of electromagnetic radiation from their magnetic poles.
• Origin: They are superdense remnants of massive stars (typically 1.4 to 2.3 times the mass of the Sun) that exploded as supernovae.
• Density: Primarily composed of neutrons, a pulsar compresses a mass greater than the Sun into a sphere about 20 km in diameter.
• Rotation: Pulsars spin at speeds ranging from several rotations per second to hundreds per second (in the case of millisecond pulsars).
• Magnetic Field: They have magnetic fields trillions of times stronger than Earth’s, which accelerate charged particles to emit narrow, laser-like beams.

How Does the Measurement Work?

• Dispersion: Astronomers measure the delay of radio pulses as they pass through the interstellar medium (ISM) to determine the interstellar electron density. Greater delay indicates a dense ‘path’ of matter.
• Scattering: They analyse how much a radio signal “smears” or spreads out as it passes through turbulent regions of the ISM. Greater blurring indicates a more disturbed or dense path of matter.
• K-Factor: By combining dispersion delay and scattering blur, a K-factor is derived to distinguish whether the medium is a single dense screen or multiple distributed layers.
• Ratio Analysis: The K-factor ratio resolves ‘distance ambiguity’ by differentiating a nearby dense cloud from a long, thin interstellar path.
• Scale Expansion: This data bypasses the 10,000-light-year limit of traditional parallax, extending cosmic distance measurement throughout the entire galaxy.
