OnGo?

“CBRS” - Describes the 3.5GHz band in the US.

“OnGo”

Describes the shared spectrum technology reflected in the work products

of the Alliance eco-system.

“Our customers are deploying a Private LTE network with OnGo in the

3.5GHz band”

OnGo Private LTE – Changing What's Possible

• Access up to 150MHz of newly available mid band

spectrum

• Expansive wireless coverage & capacity

An opportunity to deploy your own high

performing, secure private network with

reduced complexity and costs

What is CBRS?Youssef Abdelilah

CBRS 3-tiered spectrum sharing in the US

Opens 150 MHz of spectrum- Band 48 (B48) - for new commercial use without impacting incumbents

Incumbents are protected

from interference from

PAL and GAA

PAL has priority over GAA,

licensed via auction, 10 MHz

blocks, up to 7 licenses

GAA can use any spectrum not

used, yields to PAL and

incumbents

General Authorized Access (GAA)

What is Involved in an OnGo Network?

• SAS – Spectrum Access System – Manages Access to Spectrum

– Several competing systems deployed by WInnForum members

• CBSD – Citizens Broadband Radio Service Device– A base station; OnGo LTE eNodeB

– Category A – Low(er) Power: <30 dBm/10 MHz (<1 Watt/10 MHz)

– Category B – Outdoors Only, High(er) Power: <47 dBm/10 MHz (<50 Watt/10 MHz)

• EPC- Evolved Packet Core: – The evolution of the packet-switched architecture, is a

core network for packet services

• EUD – End User Device: OnGo LTE UE– A mobile (or fixed) device

– Maximum transmit power of <23 dBm/10 MHz (<200 mW)

What is Private LTE?

What is OnGo Private LTE?

• An LTE Network Not Open for General Access

• Can Be Deployed by Anyone

– Not just the usual suspects – MNOs, MSOs, MVNOs, etc.

• Limits Access to Known Devices

– Devices with a SIM (subscriber identity module) configured to access the network

• Lots of Use Cases

Survey & Planning


Do You Need a PAL?

• Generally Not, for an Indoor Private LTE

• When a PAL Is Worth Getting

– Large coverage area or outdoor deployment using Category B

CBSDs

– Mission criticality – PALs are less likely to be interfered with

– Crowded environment – Lots of CBRS networks in area

• PAL Auction Just Closed – But You Can Sublicense

– PAL holders may be willing to sublicense, but don’t have to

Survey & Planning


Will I Get Denied Access by SAS?

• Very Unlikely but Depends on Location and License

• Where Incumbents Are Operating– Mobile sources – typically along the coasts

– Fixed sites are known

• PALs Have Priority over GAA– SASs allocates GAA channels to avoid interference with PALs

– However, 80 MHz are reserved for GAA

• SASs Will Be Able To Give Information For Your Location– Incumbents in area, other GAA users, etc.

Survey & Planning


OnGo Identifiers

• Private LTE Networks Need Unique Identifiers– Ensure proper functioning

– Prevent interference with other LTE networks

• CBRS Alliance Managed Identifiers– CBRS Network ID (CBRS-NID) – identify private LTE network

– MMEGI – Identify tracking area to support mobility

– CBRS eNB ID – identify a specific base station

– Small registration/annual renewal fee

– [email protected]

• IMSI Block Number– For SIM cards in devices

– Managed by US IMSI Administrator• https://imsiadmin.com/imsi-home

Survey & Planning

https://imsiadmin.com/imsi-home

When to Use OnGo?

• When You Have Lots of Devices to Control– OnGo is able to provide consistent service and access to lots of devices

• When Consistent Performance is Needed– Reliable, controlled spectrum access

• When Mobility is Critical– Reliable handovers between access points.

• When Access Points are Difficult to Place– Higher power levels for more coverage per access point.

• When the Radio Environment is Complex– Higher power levels for better coverage

– SAS managed channel access

– LTE self-optimizing network

Survey & Planning


Example Scenario – Smart Building Planning

• Cameras Are Primary Traffic Source– 6 Mbps: 2x 3 Mbps 720p video

– <1 Mbps for all other devices

– 1 CBSD on a 10 MHz channel can serve both cameras

• 2 CBSDs Per Floor Needed for Coverage– Both are Category A (<1 Watt)

– 1 camera per CBSD

• 2x 10 MHz channels needed– 1 channel for each CBSD

Survey & Planning


Example Scenario – Sports Complex Planning

• Cameras Are Primary Traffic Source

– 3x 8 Mbps 1080p HD video

– 2x 10 MHz channels needed

• Multiple CBSDs Needed

– Category A for Indoor Spaces

– 2x Category B for Outdoors

– 3 sets of channels needed

• PAL Desired

– Outdoors deployment

– Several channels

Appendix


What is CBRS?

• Citizens Broadband Radio Service (CBRS)– 150 MHz band – 3.5 GHz to 3.65 GHz

– Previously licensed for used by US Military Radar Systems, Fixed-Wireless Access, etc.

– FCC defined rules for use of CBRS band by other participants in Part 96 regulations

• Access Divided Into 3 Tiers of Access– Incumbents – previous users of the band, may be mobile and intermittent, first priority

– Priority Access License (PAL) – preferential access, auctioned by the FCC on a per-county basis

– General Authorized Access (GAA) – allowed to use, if nobody else is

• Managed by Spectrum Access Systems (SASs)– Service that controls access to the band

– PALs, GAA only allowed to use the band, if the SAS allows it

– Models propagation and incumbent activity to ensure that incumbents are not interfered with

• PALs protected from GAA interference

• GAA is unprotected (though that is going to change soon)


What is CBRS?

• Spectrum Access System (SAS)– Centrally coordinates access to the shared

spectrum, enforcing priorities and modeling the RF environment

• Environmental Sensing Capability (ESC)– Detects incumbent activity and informs SAS so that

channels can be cleared of lower priority use

• Domain Proxy– CBSD aggregation and proxy function for large

networks, can be integrated with an EMS / NMS or be standalone

• CBRS Device (CBSD)– Radio nodes operating in the CBRS

band, must be centrally coordinatedby a SAS in order to transmit

3.5GHz CBRS Radios “CBSDs”

FCC Databases(FSS and WISPS)

SAS 1

Domain Proxy/Network Manager

Incumbent Detection (ESC)

SAS 2

Who is Involved in CBRS?

• FCC – Sets the Rules for CBRS Band Access

• Wireless Innovation Forum (WInnForum)– Wrote requirements for SAS and other system elements

– Test and certification of SAS

• CBRS Alliance (CBRSA)– Industry organization promoting 3GPP technology in CBRS band

– Develops OnGo standards for 3GPP in CBRS

– Test and certification of devices for compliance

• OnGo™

– 3GPP technology for use in the CBRS band

– LTE and 5G NR

Some Rules of Thumb

• Category A (<1 Watt) CBSD Cover 10,000 ft2 Area

• Category B (<50 Watt) CBSD on a 160 ft Antenna Has

Range of 1.5 to 2 Miles

• Throughput Will Drop With Distance

– 15/5 Mbps DL/UL per channel minimum

– Will maintain reduced throughput even at cell edge

• Anticipate 30% Data Growth per Year

Survey & Planning

Vendor Identification

• SAS Vendor– Select SAS who has best commercial/business terms

• Certified Professional Installer (CPI)– Registers CBSD info with the SAS

– WInnForum accredited training programs

• EUD (LTE UE)– The devices that will connect to the network

– LTE UEs that support Band 48 willwork out-of-the-box

• CBSD (LTE eNB)– Supports needed channels and bandwidths

– Supports needed TDD configuration

– Data/network interfaces

• Core Network (LTE EPC)– Element Management System (EMS) /

Device Management (DM)

– Features needed to support operation
