5G represents a wireless inflection point for cable companies

2

• Previous generations of mobile have focused on high speed mobility with externally deployed infrastructure with a single air interface.

• FCC decision to open 3.55-3.7 GHz for spectrum sharing based on small cells allows a wider number range of LTE providers

• FCC’s decision to open up cm/mm wave spectrum for broadband communications (10/2015) as a response to the evolution towards 5G

• 5G is driving R&D and technology development in the mm-wave bands, enabling new use cases that go beyond mobile communications

• 5G emphasis on ultra high speed with cm/mm-Wave small cells deployments could be a game changer for Cable Operators enabling them to deliver new mobile services both below and above 6 GHz


• 75% of Mobile Data is consumed inside buildings • 5G cm/mm Wave small cells are analogous to WiFi Hot spots: handover 16Gbit/s to a macrocell?• In both places Cable Operators have strategic advantages: access rights, backhaul and power

• Cable WiFi: 400K free Public Hot Spots available across the top 5 US Cable operators

• Community WiFi (Open WiFi): 9.8M

What are US Cable’s assets for 5G?

3

• 59 million US cable broadband customers with cable DOCSIS 3.0 high speed internet networks available to more than 85% of US Households

• DOCSIS 3.1 offers 10/1 Gbit/s while DOCSIS Full duplex will offer 10/10 Gbit/s

Delineating ‘5G’ Spectrum

• A range of bands is under consideration for 5G, but most are highly uncertain, particularly at the ITUØ EU likely to follow ITU decisions at 2019 World Radio Conference

• FCC may make initial cm/mm Wave bands available for 5G in 2016• 5G spectrum availability will rely on sharing spectrum with other services

3.55 – 3.7 GHz shared spectrum for future mobile

US EU / ITU Other Notes• 3.55-3.7 GHz coming available

in 2016-2017 via 3-tier access model (licensed & unlicensed)

• Access is geo database-reliant• 3.1-3.55 & 3.8-4.2 GHz under

initial discussion for mobile

• 3.4-3.8 allocated for mobile in EU, but is currently a BWA/WiMax band

• OfCom looking at mobile in 3.8-4.2 GHz despite lack of EU initiative

• 3GPP has TDD standardized for 3.4-3.8 GHz

• WINN Forum specifying database architecture (CableLabs participating)

• Satellite downlink incumbents


3.5 GHz Shared Spectrum - Democratization of LTE

• 150MHz in 10 MHz blocks (73K areas across the US)– At least 8 blocks are available for anyone to use– Up to 7 blocks are reserved in 3 year terms (PAL)– Suitable for LTE TDD terminals (3G PP Band 42/43)

• Three tiers of priority for spectrum access– Incumbent (Department of Defense, WISP, Fixed Sateliite)– Priority (PAL) tier is licensed, dynamically assigned– General (GAA) tier is effectively unlicensed

• Spectrum actively managed and allocated by SAS providers, including incumbent protection

• 28 GHz and 38 GHz offer circa 160m – 120m ranges with 16 Gbit/s• 70 GHz offers circa 50m with 35 Gbit/s


• 3.5 GHz Shared Spectrum– 150 MHz of shared spectrum is available for small cells with LTE TDD which could

allow Cable Operators to deploy LTE small cells inside homes/offices and on outside Cable Infrastructure

• 5G small cells– cm/mm wave band communications can offer opportunistic high-speed

communications especially when coupled with clusters of small cell deployments. – cm/mm wave small cells could support the same coverage as the actual LTE small

cells in dense urban areas (50-160 m cell radius) with traditional cellular bands providing the required coverage and mobility support

– Existing WiFi networks can be evolved into dense wireless networks

• Cable has strategic assets to offer mobile support above and below 6 GHz

• Fixed wireless service offerings using cm/mm wave bands– To support speeds of circa 15-35 Gbit/s per cell, over ranges of 50-160m,

with 28-70 GHz requires deep fibre access networks and base stations in proximity to end users

– However, in those places Cable has a deep metro existing Fibre/Hybrid Fibre Copper footprint with similar or greater bandwidth capacities nevertheless there may be tactical opportunities for cm/mm fixed access such as rapid service provision for businesses.

Cable Opportunities - 2

13


• 5G may present cable companies with an opportunity to become viable wireless carriers as incumbent wireless operators have to invest heavily in new technology: – 5G will utilize new spectrum that will be available for auction as well as unlicensed bands – Multi-Gbit/s speeds will be provided by widely distributed cm/mm wave small cells where Cable

has WiFi assets– Both incumbents and potential cable players will need to purchase new radio access equipment– Core networks will be redesigned with new virtualization technologies

• Cable companies are well positioned to take advantage of this transformation: – Experience with provisioning widely distributed access points both LTE and WiFi– Existing WiFi networks can be evolved into dense wireless networks – Ability to leverage existing deep metro fibre/Hybrid Fibre Copper footprint with external and

internal placement of small cells– Fixed-mobile convergence will be a central theme for efficient and effective 5G network design

5G represents a wireless inflection point for cable companies
