Spectrum Sharing● All technologies are important● Technical coexistence is possible in many cases, it is about

the licensing regime.● Clearance process are complicated and might take long time.● Spectrum sharing is an alternative to release more spectrum

for broadband (fixe and mobile), while protecting incumbents

● Dynamic spectrum access: spectrum management through technological means.

● DSA is technology neutral and supports all shared spectrum technologies that promote co-existence.○ Technology has an increasingly important role

to play in spectrum management.

○ The technology required for spectrum sharing exists — the challenge is the regulatory regime.

○ DSA supports the use of geolocation databases and other interference protection mechanisms where necessary to promote greater shared use of spectrum.

CBRS and TSSM

Ensure all parties have access to both PAL and GAA spectrum.

Supports efficient use of the band through shared access that protects incumbent services.

Supports a light-weight database to facilitate dynamic sharing in a 3-tiered framework.

TVWS

Supports increasing shared spectrum use in TV whitespace that enables cost effective broadband deployment in rural areas.

TVWS also provides good building penetration that is critically important for IoT and smart city applications.

mmWave

The propagation characteristics of mmWave bands make dynamic sharing ideal and critical to enable efficient use of spectrum.

Supports unlicensed use of the 57 –71 GHz band, including Wi-Gig and P2M mesh network services.

Supports flexible licensing rules.3D Spectrum Sharing

WI-FI 6

Supports allocation of the band for unlicensed services to meet the demand for Wi-Fi and unlicensed services that require larger channel bandwidths.

Technology management of the band can protect incumbent services while allowing greater access to Wi-Fi.

SPECTRUM SHARING IN THE UKFacilitating access to spectrum for new users plays an important role in encouraging innovation. Objectives: to increase quality wireless broadband coverage where people live, work and travel across the UK and to encourage the development of new uses which will benefit both businesses and consumers.

OFCOM is making frequencies in the 1800 MHz, 2.3 GHz, 3.8-4.2 GHz and 24.25-26.5 GHz bands available to new users via a new spectrum sharing framework.

OFCOM anticipates that spectrum will only be available to share in remote areas, where it could be used to support private networks or wireless broadband services.

CITIZENS BROADBAND RADIO SERVICE

In the U.S., the FCC has developed a spectrum sharing model called Citizens Broadband Radio Service (CBRS) to make more efficient use of the 3.5GHz band.

It is administered and enforced by a spectrumaccess system (SAS) that is designed to provide dynamic and secure allocation of spectrum resources in real time.

The SAS ensures that spectrum is always available for military applications and for other public sector incumbents at the time and place it is needed.

Page 27: SPECTRUM SHARING PAST, PRESENT AND FUTURE · 9/28/2020  · OFCOM is making frequencies in the 1800 MHz, 2.3 GHz, 3.8-4.2 GHz and 24.25-26.5 GHz bands available to new users via a

CITIZENS BROADBAND RADIO SERVICEThe CBRS is a three-tier system:

When sensors detect federal transmissions, the SAS dynamically reallocates other users in the area to alternative parts of the band.

In the second tier, spectrum is allocated to commercial users who buy priority access licenses for a specified location & period of time.

The remaining spectrum can then be used for general authorized access.

RESEARCHING THE IMT BANDSIn 2019, Policy Impact Partners (PIP) conducted in depth research into spectrum sharing models in IMT bands (similar to US CBRS) for which there are already LTE devices. The study was focused on Colombia, Malaysia and South Africa with the aim of assessing market readiness to support technology trials.

The research findings were presented at a policy workshop held in Johannesburg, South Africa in October 2019 and reported in a White Paper jointly published by PIP and the Dynamic Spectrum Alliance (DSA).

STRONG APPETITE FOR SPECTRUM SHARING IN SAAll the electronic communications licensees in South Africa interviewed by PIP expressed support for a spectrum sharing technology trial.

Sharing IMT spectrum could help provide affordable broadband to previously unserved/underserved areas of South Africa.

This is crucial to ensure communications during the COVID -19pandemic as well as to ensure in the long term that no SA citizen is left behind in the digital age.

Spectrum sharing in IMT bands can benefit from rapid infrastructure deployments, while end-users could choose from the wide variety of LTE-compatible devices from competing suppliers.

• Tier 1 users have conventional licences issued by ICASAo They indicate what spectrum they are willing to locally share

• Tier 2 users are new entrant connectivity providerso They obtain authorisation for their base stations to use

spectrum (‘T2 grants’) from a Spectrum Sharing System (SSS)• Tier 3 users are local businesses / private networks

o T3 grants are issued by the SSS and provide scope for rapid access to spectrum on an opportunistic basis.
