Transition Readiness Event – Background Reading
May 2016

2. Current service Airwave: However:
Was the first national public safety (PS) network based on the TETRA technology standard
Is used by all Emergency Services and other agencies
Is a private network using dedicated spectrum with c3,800 sites to provide full national coverage
Has underground and national air-to-ground coverage
Provides PS functionality, coverage, availability, security
National shut down is 31 Dec 19
However:
Airwave is expensive compared with similar services
Airwave cannot provide broadband data services
EU procurement legislation requires a re-competition

3. Programme objectives
Replace Airwave critical voice services by enhancing a commercial mobile network:
Improved to integrate broadband data services; PS functionality; national coverage; high availability and end-to-end security
Flexible to better match/be proportionate to demand
Less expensive to address budget pressures
Available in 2017 and complete by 2019
Meets all user, system and commercial requirements but not necessarily in the same way as Airwave
Avoids a lengthy, monolithic, single technology, expensive PFI
Open up to all mobile network operators (MNOs) post 2021

4. Approach Authority takes on the role of prime contractor and SI
Disaggregate procurement into separate lots
Re-compete contracts more regularly to exploit market forces and take advantage of technological evolution
Design, build, and test the critical public safety functionality
Provide different types of mobile devices
Support different types of business applications
Provide national air to ground coverage
Support users transition to ESN: programme management, integration and reporting; vehicle reference designs; training services
Enable integration between Airwave and ESN

5. Programme Scope Emergency Services (ES) Users:
44 Police forces
50 FRS
13 Ambulance Trusts
Non ES User Organisations:
non-Home Office police forces
other government departments
local authorities
Transport agencies and utility companies
Control rooms: c230
Vehicles: c50,000
Aircraft: c115
Users: c300,000

6. Procurement Main projects: Dependent projects: Related projects:
Lot 1: Delivery Partner (KBR)
Lot 2: User Services (Motorola)
Lot 3: Mobile Services (EE)
Related projects:
Extended Area Services
Air to Ground Services:
Network
Airborne devices
London Underground Services
Handheld, vehicle & airborne devices
Control room upgrades
WAN connections
Vehicle and aircraft installations
Coverage
Interoperability
Dependent projects:
Network Rail (Telecoms)
Crossrail
MIP
Government estates

7. Extended area services (EAS)
EAS will extend EE’s infrastructure to 97% coverage
EAS will acquire (lease or design, build and own) sites and backhaul, and maintain the infrastructure within 38 EAS areas
EE will install the active equipment and connect to their core
Satellite solutions will be considered where this is more cost- effective or timely

8. Air to ground (A2G) Services
Network to be built using existing sites
A2G base-stations linked to Lot 3 core via backhaul
Two TDD-LTE devices
Spectrum - 2.3GHz with MOD
Aircraft wireless system
Seamless transition from ground to A2G networks
Voice and broadband data to replicate ground users
Central procurement of radio system and service arrangement
Users install and maintain

9. User devices
Lot 2 (User Services) will approve user devices and accessories
3ES will procure user devices through a framework from approved suppliers
User devices will include:
Handheld devices that are commercial off-the- shelf phones,
most will be ruggedized
Vehicle mounted devices
Aircraft mounted devices
Gateways
Market Engagement continues to provide reassurance
Supplier demonstrations show lots are available today 9

10. Control room upgrade
Control room upgrades to access ESN functionality will be coordinated by the Programme. The aim is to upgrade before the commencement of transition
Inter-working during transition will now be delivered centrally
Control room system upgrades will be procured locally
Upgrades will be required to a range of systems, including:
ICCS
Mobile Data Systems
Mobilising systems
Command and Control Systems
Control room systems
WAN connections (DNSP)

11. Inter-working Gateway
Inter-working is the ability for users to make calls between the Airwave and ESN networks during transition
Multiple technical options having been considered the decision is to connect the networks using Motorola Inter-working Gateway
Special arrangements for non standard services (NSS)
ICCS & other
Control Room
systems
NOW
Motorola
Inter-working Gateway
DNSP
END GAME:
ICCS and other CR
systems fully integrated to ESN

12. London underground services (LUS)
Solution required by the end of 2017
Interim solution:
Exploit TfL’s WiFi infrastructure to provide ESN in the stations
Extend TfL’s Connect infrastructure to provide ESN in the tunnels
Fall-back is to use Airwave in LU (ALU):
Dual-mode (LTE/TETRA) devices
Interconnect via control room ICCS
Extend ALU if necessary post 2019
Long-term solution:
TfL implement 4G 12
