4G-FUTURE WARRIOR
1.ABSTRACT
Information is power, nowhere is this truer than on the battlefield, where the ability to communicate clearly and rapidly pass on information spells the difference between survival and death? 4G (4th Generation) is the technology that is going to drive a soldier in the field in future. The key to empowering the military with tactical broadband voice, video and data is 4G communications technology. This technology adopts Wireless technology on the platform of fixed networks, Advanced antennae technologies and More advanced wireless security technologies. Next thing is about the gear for the future warrior. Our system provides a enhanced power of vision, which provides Ground Guidance, Unit Detection, Soldier Status, Target Hand-Off and provides the Soldier Rescue during the battle. The uniform along with the armor, onboard computer which will monitor soldiers' overall physiological and psychological picture of how they are performing in the battle zone and enhanced human performance which weighs 50 pounds from head to toe against 120 pounds of the current day system present.
2.WHAT IS 4G?
Fourth generation mobile communications systems that are characterised by high-speed data rates at 20 to 100 Mbps, suitable for high-resolution movies and television, virtual . Initial deployments are anticipated in 2006-2010.
It is Also known as ‘Mobile Broadband everywhere’
MAGIC

3.INTRODUCTION
The new systems include a weapon, head-to-toe individual protection, onboard computer network, soldier-worn power sources, and enhanced human performance. "The Future
Warrior will be a responsive and formidable member of an
invincible battle space team". The Future Warrior system
will meet the more immediate, short-term demands of our
fighting warriors in the battle space, and will remind you of
an ominous creature out of a science fiction movie.
4.TECHNOLOGY
The approach will support military operations across a spectrum of environments from backpacks to ships. The key technology supporting these initiatives is ad hoc peer-to-peer wireless networking (ad hoc p2p), also known as a mobile mesh network. Ad hoc p2p operates by taking a collection of mobile terminals (such as handheld devices and vehicular systems) that communicate directly with each other without the aid of established infrastructure. Ad hoc networking provides a selforganizing and self-healing network structure. Multi-hop routing terminals act as routers and relays for each other, and extend the range and coverage of communications links between individual soldiers, troop transports and command centers.
5.THE BASIC DESIGN
The military and DARPA have outlined specific capabilities for these devices. At a minimum, they will need the following setup processes that are essential for a good and effective communication between the soldier and his troops.
5.1 Deploy-ability with little or no fixed infrastructure:
Military engagements are often spontaneous, and a communications solution needs to be, as well. 4G Warriors bring their networks with them, and take them away when they leave. Network setup automatically begins the minute troops exit a transport, helicopter or ship.
5.2 Geo-location well beyond the limitations of GPS:
Soldiers cannot afford to expose themselves on a
battlefield to acquire GPS coordinates. GPS is also limited
in that satellite signals cannot penetrate caves, underground
bunkers or inside shielded buildings. Ad hoc p2p wireless
has built-in geo-location using an extremely accurate form
of triangulation. The 4G Warrior can triangulate his or her position, or that of another soldier, based on mesh-enabled
vehicles or other devices, even when hiding in caves or
otherwise out of harms way. Readings are faster than GPS
(under a second) because soldiers dont have to wait for
multiple satellites to acquire a fix.
5.3 Security :
The device security must address both communications security (COMSEC) and a way to protect the network from unauthorized use if the device is captured. Communications are more secure when mesh networks allow for route diversity. Meshed architectures also allow devices to transmit at lower output power to neighbours rather than Shouting at a cell tower.
5.4 Anti-jamming robustness :
The 4G Warrior is neither dependent on a single frequency nor constrained to a military band. These self-forming, self-healing networks will have the ability to instinctively and proactively reduce the probability of jamming. Communications devices must operate while vehicles or soldiers are mobile, even at speeds in excess of 100 mph. 4G Warriors can receive real-time Drone flying over a battlefield. Multi-tap rake receivers minimize the effects of Doppler radar to maximize the impact of theater air assets.
5.5 End-to-end IP :
Modern soldiers grew up with computers and will demand the same applications and user interfaces available to civilians. The 4G Warrior, using instant messaging, can send photos of enemy positions back to the camp for analysis, and use voice over IP to communicate with nonmilitary phones in an occupied city.
6. 4G ON THE BATTLEFIELD
All of the battlefield network devices including those embedded in tanks or other vehicles will instantly form, heal, and update the network as users come and go. That is, they will associate in an ad-hoc manner. Moreover, the devices will automatically and continuously optimize network connections as users merge in and out of the network at will. As intelligent elements, all of the
devices will constantly reconfigure routing tables to determine the best network routes and, unlike cell-based solutions, network coverage and service levels will improve when soldier density increases. The network resources are better utilized because networks are self-balancing, as well. The soldiers subscriber devices can hop to distant network access points, away from points of congestion, shifting network capacity to meet demand. Network deployment will be fast and easy because it is tower less. Communication systems providing the backhaul and the network will disappear as fast as it was formed once soldiers leave the area. The 4G battlefield will be entirely mobile, with satellites or other. This technology could function as a personal are network (PAN), local area network (LAN), or wide area network (WAN), simultaneously. This means that the same network can connect a soldier to the squad or platoon, to the battalion, and to a fully mobile division. It is the equivalent of a Bluetooth, 802.11, and 3G convergences, but in a single network, with a single device.
