Military Exercises and IT Telecom: India's Ballistic Missile Defence system
- The Indian Ballistic Missile Defence Programme, an initiative to develop and deploy a multi-layered ballistic missile defence system, is a two-tiered system consisting of two interceptor missiles, namely Prithvi Air Defence (PAD) missile for high altitude interception, and the Advanced Air Defence (AAD) Missile for lower altitude interception. The two-tiered shield will be able to intercept any incoming missile launched 5,000 km away.
- The Ballistic Missile Defence programme aims to provide an effective missile shield against incoming enemy ballistic and nuclear missiles.
- A hostile missile needs to be intercepted at boost (launch) point, mid-course (flight through space), or terminal phase (during atmospheric descent).
Components
- Prithvi Defence Vehicle: It is capable of killing an incoming missile with a strike range of around 2,000 km outside the earth’s atmosphere. It will replace the existing Prithvi Air Defense (PAD) which has a maximum interception altitude of 80 kilometres.
The advantage of intercepting an incoming missile at such a high altitude is that the debris would not fall on the ground and there would be no collateral damage. - Advanced Air Defence: The endo-atmospheric missile, capable of intercepting incoming targets at an altitude of 15 to 25 km successfully destroyed the incoming missile.
Military Exercises and IT Telecom: Anti-Satellite Test (ASAT)- Mission Shakti
- On March 27, 2019, India conducted Mission Shakti, an anti-satellite missile test, from the Dr A P J Abdul Kalam Island launch complex. This was a technological mission carried out by DRDO. The satellite used in the mission was one of India’s existing satellites operating in a lower orbit. The test was fully successful and achieved all parameters and it required an extremely high degree of precision and technical capability.
- The significance of the test is that India has tested and successfully demonstrated its capability to interdict and intercept a satellite in outer space-based on complete indigenous technology. With this test, the country joins an exclusive group of space-faring nations consisting of USA, Russia, and China.
- The government has stated that it has no intention of entering into an arms race in outer space. The country has always maintained that space must be used only for peaceful purposes. The government has also stated that India is against the weaponization of Outer Space and support international efforts to reinforce the safety and security of space-based assets.
- India is also a party to all the major international treaties relating to Outer Space. India already implements several Transparency and Confidence Building Measures (TCBMs) – including registering space objects with the UN register, prelaunch notifications, measures in harmony with the UN Space Mitigation Guidelines, participation in Inter-Agency Space Debris Coordination (IADC) activities about space debris management, undertaking SOPA (Space Object Proximity Awareness and COLA (Collision Avoidance) Analysis and numerous international cooperation activities, including hosting the UN-affiliated Centre for Space and Science Technology Education in Asia and Pacific. India has been participating in all sessions of the UN Committee on the Peaceful Uses of Outer Space.
- India also supported UNGA resolution 69/32 on No First Placement of Weapons on Outer Space. Equally, India supports the substantive consideration of the issue of Prevention of an Arms Race in Outer Space (PAROS) in the Conference on Disarmament where it has been on the agenda since 1982.
Military Exercises and IT Telecom: Important Indian Defence Missions
The Indian Armed Forces are the overall unified military of the Republic of India encompassing the Indian Army, the Indian Air Force and the Indian Navy. The President of India serves as the commander-in-chief of the armed forces. With an estimated total active force of 1,325,000 personnel, India maintains the world’s third-largest armed forces after China and the United States.

Military Exercises and IT Telecom: Nuclear Triad
- A nuclear triad is a three-pronged military force structure that consists of land-launched nuclear missiles, nuclear-missile-armed submarines and strategic aircraft with nuclear bombs and missiles.
- Specifically, these components are land-based intercontinental ballistic missiles (ICBMs), submarine-launched ballistic missiles (SLBMs), and strategic bombers.
- The purpose of having this three-branched nuclear capability is to significantly reduce the possibility that an enemy could destroy all of a nation's nuclear forces in a first-strike attack. This, in turn, ensures a credible threat of a second strike, and thus increases a nation's nuclear deterrence.
- It includes the following components:
- Bomber aircraft: Aircraft carrying nuclear bombs, or nuclear-armed cruise missiles, for use against ground or sea targets.
- Land-based missiles (MRBMs or ICBMs): Delivery vehicles powered by a liquid or solid-fueled rocket that primarily travel in a ballistic (free-fall) trajectory.
- Ballistic missile submarines (SSBNs): Nuclear missiles launched from ships or submarines. They are classified under an umbrella of vessels and submarines that are capable of launching a ballistic missile.
- India’s Nuclear Triad
- India's nuclear weapons policy is that of "no first use" and "minimum credible deterrence," which means that the country will not use nuclear weapons unless they are attacked first, but the country does have the capability to induce the second strike.
- India completed its nuclear triad with the commissioning of INS Arihant in August 2016, which was India's first submarine built indigenously.
- INS Arihant is a nuclear-powered ballistic missile submarine armed with 12 K-15 missiles with a range of 750 km, which will later be upgraded K-4 missiles with an extended range of 3500 km.
- In November 2017, it tested the BrahMos missile from the Sukhoi-30 MKI platform. The INS Arihant was the first SSBN to be completed under India's program.
- The INS Arighat is currently under construction and close to completion. This would be the second SSBN of the three underway to be finished.
- After the INS Arihant was completed, India now contained air-launched nuclear missiles, nuclear-missile-armed submarines and strategic aircraft with nuclear bombs and missiles. This allows the country to join the nuclear triad.
Military Exercises and IT Telecom: Telecommunication Technology: IT and Computer
- The telecom services have been recognized the world-over as an important tool for socio-economic development for a nation.
- It is one of the prime support services needed for rapid growth and modernization of various sectors of the economy.
The two telecom technologies are:
GSM
- GSM (Global System for Mobile communication) is a digital mobile telephony system that is widely used in Europe and other parts of the world.
- GSM uses a variation of time division multiple access (TDMA) and frequency division multiple access (FDMA).
- GSM digitizes and compresses data, then sends it down a channel with two other streams of user data, each in its own time slot.
- It operates at either the 900 MHz or 1800 MHz frequency band.
- The key advantage of GSM systems to consumers has been higher digital voice quality and low cost alternatives to making calls, such as the Short message service (SMS, also called “text messaging”)
CDMA
- Code-Division Multiple Access is a digital cellular technology that uses spread-spectrum techniques.
- Individual conversations are encoded with a pseudo-random digital sequence. CDMA employs analog-to-digital conversion (ADC) in combination with spread spectrum technology. Audio input is first digitized into binary elements.
- The frequency of the transmitted signal is then made to vary according to a defined pattern (code), so it can be intercepted only by a receiver whose frequency response is programmed with the same code.
- CDMA consistently provides better capacity for voice and data communications than other commercial mobile technologies, allowing more subscribers to connect at any given time.
- The technology is used in ultra-high-frequency (UHF) cellular telephone systems in the 800-MHz and 1.9-GHz bands.
Military Exercises and IT Telecom: Different Telecom Technologies
1. VOIP (Voice over Internet Protocol)
- VOIP is IP enabled voice calling technology over internet. Example: Skype, Yahoo messenger, MSN messenger.
- It requires broadband connectivity to make a call along with IP enables devices like Computers, Smartphone etc.
- The voice is converted into digital packets and transmitted to destination over packet switched network.
2. IPTV
- IPTV is new generation TV that communicates over Internet protocol in the form of packets rather than signals in normal TV’s.
- It has 3 components: IPTV where content is encoded and decoded; Delivery Network over which information in the form of packets is transmitted; Setup Box which is communication link between operator’s broadband modem and customer’s TV. Also packets delivered are reassembled here.
- IPTV enables two-way interactivity, in contrast to traditional one way cable or satellite broadcast network. The two-way IPTV network means viewers have more options to personalize interact and control their viewing experience.
- Because IPTV is based on internet protocol, it is sensitive to packet loss and delays if the IPTV connection is not fast enough.
3. Near Field Communication (NFC)
- It’s a new standard of wireless communication.
- It enables users to transmit radio frequency wave over a very short distance just about few centimeters.
- Since it’s a very short range communication, power consumption is very negligible or no power consumption.
- It can transfer low amount of data between devices enabled with NFC.
- No need of pairing the devices, its ready to use at just a click or swipe.
- NFC-based wallet, Mobo Money launched- Tech Mahindra, the Tech & Software development arm of Mahindra Group, announced launch of Mobo-Money, a NFC based, contactless digital payment ecosystem.
- Mobo Money will be the first commercial roll-out of NFC (Near Field Communication) for an ecosystem. The company aims to get about one million merchants including local kirana shop owners on board.
4. Li-Fi
- Li-Fi means light fidelity.
- Li-Fi is a wireless communication, high speed and bidirectional.
- It’s similar to WiFi but not a radio frequency wave communication.
- It’s a visual light communication where visible light has the capacity to transmit the data.
- A dedicated LED light so developed emits a visible range light. The reach of light is the range of Li-Fi communication.
- Internet connectivity would become more simple and high bandwidth of Li-Fi can render cost effective and efficient data communication.
- Most importantly Li-Fi is high security benefits. Light communication can’t be intercepted unlike electromagnetic waves. Hence its secure mode of communication.
- Since light can’t pass through obstacles like walls and barriers, Li- Fi can’t work beyond it. It limited to visible range of light.
- It provides one point solution to signal solution. In offices a merely LED bulb can work as network generator.
5.Bluetooth technology
- Bluetooth is a proprietary open wireless technology standard for exchanging data over short distances (using short wavelength radio transmissions in the ISM band from 2400-2480 MHz) from fixed and mobile devices, creating Personal Area Networks (PANs) with high levels of security.
List of applications
– Wireless control of and communication between a mobile phone and a hands free headset
– Wireless Bluetooth headset and Intercom.
– Wireless networking between PCs in a confined space and where little bandwidth is required.
– Wireless communication with PC input and output devices, the most common being the mouse, keyboard and printer.

– Wireless networking between PCs in a confined space and where little bandwidth is required.
– Wireless communication with PC input and output devices, the most common being the mouse, keyboard and printer.
– Transfer of files, contact details, calendar appointments, and reminders between devices with OBEX.
6. Wi-Fi technology
- Wi-Fi is a mechanism for wirelessly connecting electronic devices.
- A device such as a personal computer, video game console, smartphone, or digital audio player, when enabled with WiFi, can connect to the Internet via a wireless network access point.
- Wi-Fi works with no physical wired connection.
- It uses radio frequency (RF) technology, RF being a frequency within the electromagnetic spectrum associated with radio wave propagation.
- Wi-Fi is supported by many applications and devices including video game consoles, home networks, PDAs, mobile phones, major operating systems, and other types of consumer electronics.
- Wi-Fi allows cheaper deployment of local Area Networks (LANs). Products designated as “Wi-Fi Certified” by the Wi-Fi Alliance are backward compatible. Unlike mobile phones, any standard Wi-Fi device will work anywhere in the world.
7. WiMax technology
- WiMax (Worldwide Interoperability for Microwave Access) is a wireless broadband technology, which supports point to multi-point (PMP) broadband wireless access.
- WiMax can provide Broadband Wireless Access (BWA) up to 30 miles (50 km) for fixed stations, and 3 – 10 miles (5 – 15 km) for mobile stations.
Uses of WiMax technology are:
- Providing portable mobile broadband connectivity across cities and countries through a variety of devices.
- Providing a wireless alternative to cable and DSL for “last mile” broadband access.
- Providing data, telecommunications (VoIP) and IPTV services (triple play).
- Providing a source of Internet connectivity as part of a business continuity plan.
8. AMOLED Display
- AMOLED (active-matrix organic light-emitting diode) is a display technology for use in mobile devices and televisions.
- OLED describes a specific type of thin-film-display technology in which organic compounds form the electroluminescent material, and active matrix refers to the technology behind the addressing of pixels.
- AMOLED technology is used in mobile phones, media players and digital cameras, and continues to make progress toward low-power, low-cost and large-size (for example, 40-inch) applications.
- The greatest advantage of AMOLED display is fast pixel switching response time that makes the display fit and efficient for animation.
9. 4G LTE Vs 4G WiMAX
- LTE stands for Long Term Evolution. It’s a first generation 4G technology termed as “true 4G”.
- WiMAX stands for Worldwide Interoperability for Microwave Access.
- They differ in their bandwidth; LTE has higher bandwidth than WiMAX.
- LTE is compatible with existing network but for WiMAX we need altogether new network.
- The cost of installation of LTE is more than WiMAX.
- Overall LTE is gaining popularity and hopes to existing 4G technology in coming years.
10. LTE – Long Term Evolution
- LTE (Long Term Evolution) is a wireless broadband technology designed to support roaming Internet access via cell phones and handheld devices.
- With its architecture based on Internet Protocol (IP) unlike many other cellular Internet protocols, Long Term Evolution supports browsing Web sites, VoIP and other IP-based services well.
- LTE can theoretically support downloads at 300 Megabits per second (Mbps) or more based on experimental trials.
11. WiBro
- WiBro (Wireless Broadband) is a wireless broadband Internet technology developed by the South Korean telecoms industry.
- WiBro (Wireless Broadband)communication technique uses radio waves (frequency of 2.3 GHz) and allows a maximum theoretical speed of 30 megabits per second over a range between 1 and 5 kilometers.
- WiBro is a wireless point to point communication technique, tailored to serve low-cost sparsely populated areas where the fiber is not an option.
12. GPRS
- General Packet Radio Services (GPRS) is a packet-based wireless communication service that promises data rates from 56 up to 114 Kbps and continuous connection to the Internet for mobile phone and computer users.
- GPRS facilitates instant connections whereby information can be sent or received immediately as the need arises, subject to radio coverage. No dial-up modem connection is necessary. This is why GPRS users are sometimes referred to be as being “always connected”.
- GPRS packet-based services cost users less than circuit-switched services since communication channels are being used on a shared-use, as-packets-are-needed basis rather than dedicated to only one user at a time.
- Packet switching means that GPRS radio resources are used only when users are actually sending or receiving data. Rather than dedicating a radio channel to a mobile data user for a fixed period of time, the available radio resource can be concurrently shared between several users.
- This efficient use of scarce radio resources means that large numbers of GPRS users can potentially share the same bandwidth and be served from a single cell.
13. WAP
- Wireless Application Protocol (WAP) is a secure specification that allows users to access information instantly via handheld wireless devices such as mobile phones, pagers, two-way radios, smartphones and communicators.
- WAP is supported by all operating systems WAPs that use displays and access the Internet are called micro-browsers i.e. browsers with small file sizes that can accommodate the low memory constraints of handheld devices and the low-bandwidth constraints of a wireless-handheld network.
- Although WAP supports HTML and XML, the WML language (Wireless Markup Language) is specifically devised for small screens and one-hand navigation without a keyboard.
