Virtual reality or virtual realities (VR), which can

be referred to as immersive

multimedia or computer-simulated

reality,[1] replicates an environment that simulates

a physical presence in places in the real world or

an imagined world, allowing the user to interact in

that world. Virtual realities artificially create

sensory experiences, which can include sight,

touch, hearing, and smell.

Enhanced Mobile Broadband

To increase 1000x channel capacity• More spectrum => Use of higher frequencies

• Higher SNR => Interference mitigation/ smaller cell size

• More antennas => Massive MIMO

• More base-stations => NVF/ Dense small cell network

What would be the 5G

network look like?


Impacts on Infrastructure

How can 5G networks address diverse use cases?- Use cases have distinct and stringent performance expectations

- Need varying degree of adaptability to efficiently and dynamically use radio resources

Technology trends- Technology is improving: RAN enhancements for improved data rate, improved spectrum

efficiency, improved reliability, and reduced latency

(e.g. HetNet UDN, FD-MIMO massive MIMO, cell centric device centric, etc.)

- Configurability: Advances in software configurability that allows new 5G infrastructures.

- Network function virtualization (NFV) and software defined edge/cloud infrastructures

- Networks could be configured to meet application demands (e.g. data rate, number of

connections, latency, etc.)
