Future information networks will be designed with the ability to recognize patterns from which they can learn automatically and behave intelligently when confronting new data traffic patterns, and channel model patterns. Signals transmitting data across networks will be able to detect obstacles (e.g. interference/traffic congestion) or easy pathways (e.g. good wireless channels) and optimize the routing.

By combining space and time into a single manifold, physicists have significantly simplified a large number of physical theories, as well as described in a more uniform way the workings of the universe at both the supergalactic and subatomic levels. Theoretical results suggest that space-time has some discrete aspects at the Planck scale. Taking this idea further, a wireless network will be modelled on space, and time dimensions. The network resources such as signal strength, bandwidth and time will be mapped to a space-time lattice (3 dimensions in space and a fourth dimension of time). The Voronoi region of this lattice is a recognizable pattern and will be used for intelligent data transmission and routing. The signal transmission scheme (data encoding) on each wireless transceiver will again be carved from an appropriate high dimension lattice, which will be embedded within the space-time lattice.

The joint design of the space-time and data encoding lattice points will be based on strong cryptographic primitives. Cryptographic primitives derived from high dimensional lattices have been shown to be resistant to Quantum computers. This will ensure a data network, which is secure across space and time dimensions.

Network service providers will use a continuous, real-time price bidding mechanism to bid for an appropriate space-time lattice state-space. After a stable/equilibrium point is reached, different networks will work on a specially assigned carved space-time lattice, which does not intersect with lattice points assigned to other Network service providers. The space-time lattice can be thought of as a dynamical system, with each point having its own internal dynamics and coupled to nearby points. The state transition across the lattice points has to be controlled to ensure stability and robustness of the complex network system. Network operators will use feedback control techniques over the 4 D space-time state space to optimize the use of radio resources, and provide appropriate service level guarantees to their users.

The overall design objectives of future networks can be achieved.
1. A compact, space-time lattice modelling will ensure a dense packing of wireless infrastructure and mobile devices.
2. Stability and robustness of networks, ensuring scalability and reliability.
3. Security.
4. Cost effective and optimized use of radio resources.
5. Seamless mobility of wireless transceivers and infrastructure.
These features will have broader implications on Telecom policies. The ITU will play a major role in framing policies for supporting scalable, sustainable and dynamic Future networks.
