3. The Spectrum Crunch November 2017 The need for alternatives
Mobile data offload onto Wi-Fi continues to explode. Cisco forecast by % of mobile traffic will be offloaded from the cellular network to Wi-Fi
With traffic estimated to be >130 EB per month and a forecast of 542million Wi-Fi hotspots there is the requirement to address an impending interference issue
Continual drive to densify cells, enhance protocols and try new technologies that can work in harmony with intelligent devices to enhance the experience of consumers.
Potential requirement to “offload” some of the offload traffic from Wi-Fi to maintain the Broadband user experience on the primary access method of cable customers.
LC has a conceivable opportunity to play a role in this ecosystem

5. Service Defined Radio November 2017
Offloading data based on the application and device
Devices have ever increasing number of radios (Wi-Fi, Bluetooth, Cellular, NFC, mmWV)
Different applications require different traffic profiles.
High Throughput vs Low Throughput, Low latency vs latency agnostic, jitter sensitive vs jitter extraneous.
This is defined by the application being used and the service it is providing
has very low sensitivity whereas UHD online gaming demands high throughput, low latency and jitter
The ability to offload less demanding traffic to other technologies assisting in maintaining the Wi-Fi QoS for demanding applications is a conceivable use case
Homes have the infrastructure already deployed with lights and powerlines

6. IoT and the Connected Home
November 2017
IoT and the Connected Home
Massive M2M communication as we move into the next decade
Intel believe the average home will have 50 devices by 2020.
Longer term this number is likely to increase greatly as the proliferation of devices in the home reporting diagnostics and maintenance to manufacturers increases, potentially without the explicit interaction of the consumer
Opportunities exist to utilize LEDs and displays on whitegoods and other previously unconnected devices to transmit data on demand and maintain a QoS on existing Wi-Fi infrastructure
IoT Traffic Characterization programme underway at CableLabs to assess the likely impact of IoT traffic on the home network and gateway

8. Smart Buildings November 2017 B2B2C
Building owners moving towards Property as a Service model
Require apartments to be pre-connected, automated and provide communications to tenants in a seamless manner
Broadband increasingly seen as part of the service provided in shared accommodation
Ability to distribute data connectivity for people and devices using existing deployed infrastructure across not only the apartment but all shared access and facility components
Slide 8

9. Enterprise November 2017 High density multiple devices per person
Very high interference issues in office spaces and commercial buildings
Demand is often for quality over throughput to enable sensitive applications such as voice to be run over a common infrastructure
Increasingly transient workforces and portable devices challenge the Wi-Fi infrastructure
Opportunity to offload some services that do not demand immediate high throughput such as to protect voice and video services

10. Transportation November 2017
Mass transportation systems all contain existing lighting solutions
Dense environment with significant mobility challenges
High demand for services and drive to increase productivity of consumers while using mass transportation systems
Focus is currently on the development of command and control of the transportation systems themselves and not necessarily the future of connectivity on board for the transportee
Potential to provide high speed fronthaul solutions for transportation customers

11. Healthcare November 2017 An Access Point per bed?
NHS in the UK is a large B2B customer and opportunity to provide enhanced services to its customers
Challenging RF environment in many older hospitals
High demand for connectivity based on nature of time spent in single locations
Older infrastructure with priority to critical care provision

13. Requirements on LC November 2017
Current requirements from a MSO perspective
Area
Requirements
Details/Examples
Throughput
Minimum 100 Mbps; Ideal >1 Gbps
Providing full enhanced connectivity beyond that available today
Latency
Improvement on ax targets (<5ms)
Issues being seen in latency on WiFI in future use cases
Jitter
0 ms as a target
Variable latency causing issues on multiple use cases
Propagation
Full performance at 5 meter distance between Tx and Rx
Transmitter Density
Ability to densify to 10 lights per sqm
Receiver Density
10 devices per LED
IoT Uptake
Roaming
Seamless handover between lamps
Security
Secure connection between Tx and Rx
Maintain compatibility with existing/emerging authentication/association methods
Availability
Full performance at 350 lux in commercial use cases connectivity at 50 lux in residential use cases
Interoperability
Able to roam to standard connectivity when out of LC zone. Ability to manage network selection based on demand
Integrated as part of a 5G ecosystem through LWA and LWIP
Propagation 2.4m UK house ceiling, 2.7m minimum commercial height so hypotenuse 3.82m. If ceiling is 3.5m hypotenuse is approx 5m

15. LC has a potential role to play
November 2017
LC has a potential role to play
Requires a collaborative approach
Infrastructure exists to create a different LAN in a wide range of locations
Demand is ever increasing from both people and machines
Networks need to become a man of many faces. The ability to service consumers and enterprises based on location, demand and application rather than a pure device to network connection challenge.
LC provides and opportunity for an ultra-dense, low opex network in many potential scenarios, some of which have been outlined in this pack
