Nordisk Mobiltelefon - CDMA Development Group
Nordisk Mobiltelefon Offering to Public Safety users in Scandinavia May 2007 Johan Jobér Background Privately owned by founder Arnfinn Röste, employees, and investors Networks under construction. Currently around 70% area coverage in Norway. Sweden and Denmark covered by end 2006. Combine state of the art multipurpose radio access technology with nationwide coverage A high grade 3G/broadband/PAMR/Positioning network - CDMA 2000 450 MHz licenses – better rural and urban coverage High grade rugged terminals under development Primary market are niches not well served by other commercial networks Public Safety users Rural Broadband and telephony Professional users that need nationwide 3G coverage and/or PAMR Nordic licenses in the 450 MHz band Total population 9+4.6+5.4+10+35 =65M 385 000 km2 4.6M 450 000 km2 9M 43000km² 43000km² 5.4M UMTS in Norway Source: Telenor Current CDMA coverage in Norway Coverage in Norway UMTS in Sweden CDMA 450 MHz Plan Capacity advantage of using CDMA 450 TETRA CDMA with Push To Talk functionality Expanding capacity for normal calls or data is expensive with TETRA Efficient algorithms for group calls – AND huge capacity available when needed Queing between groups may happen often! (May make the call setup signalling time irrelevant in many cases) Up to 2.4 MBps data Efficient algorithms for group calls using few channel resources Mixed use of large resource pool among public and public safety users. Group calls, normal voice calls and ADSLlike data performance available How Nordisk Mobiltelefon is changing the feasibility of using the public networks for public safety? Commercial focus by operators and vendors This is an explicit target area for us – technically and commercially Even the hardest area, PAMR, has now been resolved Cooperation with SAAB Communication for systems integration and security approvals Suitable terminals Development of rugged PAMR/1x/EV-DO/gpsOne terminal Direct mode will be added later if enough users justify it, but primarily we adress network availability by redundant coverage solutions Coverage Our explicit objective is coverage ”everywhere” using the 450MHz band Reference With our service on the market, our network will be much cheaper and offer greater capabilities than new dedicated networks We offer support to other CDMA operators that wish to follow our concept Our Service offering in the MESA context Type Personal Area Network (PAN) Incident Area Network (IAN) Jurisdiction Area Network (JAN) Extended Area Network (EAN) Scope Single subject or object Capabilities Limited applications and location An incident or specific event. Examples include a MESA-capable ad-hoc "hot-spot" or other temporary network An entire jurisdiction. Examples include a traditional land mobile system or an incident-oriented MESA jurisdictional system of systems Unlimited, as technically feasible Application varied and flexible network establishment, but location limited Varied applications and locations, robust, well managed Varied applications and locations as technically feasible; could include national or territorial service, database access, enhanced access capabilities and alternate communication channels Bandwidth Required Only enough for pre-designated and localized applications Enough to support the incident or specific mission, including ad-hoc capabilities across environmentally challenging scenarios Able to provide high bandwidth throughout the coverage area; extensive planning and engineering Unlimited, as technically feasible Possible future offering? Current offering Increasing capacity, coverage and redundancy Start with umbrella cells Add lower base stations as better urban indoor coverage and capacity is needed Redundant coverage of urban areas High availability of umbrella sites Piggybacking on public CDMA 2000 system Functionality PAMR based on 1x with professional performance Broadband data (EV-DO Rev 0, Rev A, ...) Positioning with GPSOne Programmable terminals (user interface, encryption, etc.) Rapid evolution (>300 Msubs) Budget impact Lower CAPEX and OPEX cost of infrastructure Only some fraction need to be paid by the government Lower terminal cost Can use commercial ASICs => Low cost terminals Capacity There is a lot more capacity available to public safety users if using a certain fraction of capacity in a public network with priority than if a dedicated system is deployed Rollout Nationwide coverage driven by commercial rollout Coverage and availability improvement driven by public safety users Usage example Public Safety PTT, Wireless Broadband data Rugged PC’s WiFi in vehicles for Video conferences in ambulances Coastguard, police cars – tracking, etc. Private Safety RFID type scanning for Security guards Marking of important packages, machines, etc – machine to machine type services Personnel Safety Hunting, skidoo tourism, skiing, etc. Boats Moose crash safety! Authorities Corporate Consumers A Multi-Purpose Network - Fulfilling real needs ”Fixed” telephone with data and fax connector which does not require expensive copper line and monthly fee Broadband where there is no ADSL, mobile broadband or as broadband fallback 3G telephony with Nordic coverage PMR and Dispatch radio with ”unlimited” coverage, 3G, positioning, programmable emergency button, and broadband. Nextel type services. Positioning and telemetry module to track vehicles, transports, boats, boxcars, etc. Priority subscriptions for public safety, police, ambulance, etc. Confidential Information Tablet PC with Windows Fixed mount modems USB ”stick” style modems Flash-card modem for PDA use Small form factor: 60x45x20mm, 76g Standard 1330mAh battery, 20 days of operation with 1 fix per 15 mins - Optional 5000mAh battery for +2 months of operation Device tracking with a PC Web interface or on a handset Satisfying PMR/PAMR users Professional grade terminals Under development Quick set-up time Shall not be too different from TETRA (1-2 s/200 ms) Availability of some fundamental functions such as Late entry Group management and dispatch Basic priority (Normal call/PAMR call etc.) Queing with and without priority Dispatch break-in and group status Possibility to integrate with existing systems Large capacity (many users in the same group in the same cell at the same time) Support by several suppliers Road map with a future development In operation and it works... Interest from system integrators Several system integrators have taken an interest in the CDMA 450 network since a network with almost total coverage for voice and data often solves one of their main problems to develop applications for their customers. Example in newspaper article from Ny Teknik (major technology newspaper in Sweden), outlining SAAB Communication’s interest in the CDMA 450 network Source: www.nyteknik.se We offer our network capacity and support to systems integrators that wish to develop applications
