3 Belgium and ASTRID: some figures Belgium: 10 million inhabitants square kilometres 10 provinces 1 capital region 3 regions 3 communities 3 languages 6 governments 589 communities ASTRID, the initial challenge: 435 EADS TETRA base stations 11 EADS DXT switches 11 Intergraph control rooms 225 Tecnomen POCSAG paging base stations 1 National Network Control Centre 1 Mobile TETRA Base Station Special coverage locations (50 tunnels, 3 metro systems, 5 railway stations, Brussels National Airport) 3

4 Why a new radio network? Challenges of conventional analogue PMR networks Heterogeneous networks within a single user organisation Isolated networks within a single user organisation Incompatible networks between different user organisations Inefficient frequency usage Expensive and bad encryption Inflexible for user reorganisation Benefits of the ASTRID TETRA network A single countrywide intelligent cellular network Many virtual private networks Trunked network Digital network Secured network 4

5 Sharing a single common nationwide TETRA network Other benefits: Operational Enhanced functionality Simpler Cross-border operations Economical Lower network management cost (single management organization & infrastructure) Higher equipment volumes lower prices Environmental Lower number of base stations sites 5

6 Why a new (police) control room network? Challenges of old police control rooms Heterogeneous communication systems Heterogeneous information systems No Geographical Information Systems No data communication No information exchange No Information Technology and information management Inefficient use of resources Benefits of the ASTRID CAD network IT support for workflow and processes Integrated systems Data communications Information exchange Information management and reports 6

7 Nationwide shared network - consequences High financial investment: High profile political environment - media attention Many parties with different objectives involved : Very complex stakeholders environment Big project: Roll-out effort versus new requirements => High complexity 7

13 TETRA IP data 13

14 TETRA connected control room application client 14

15 More data less voice productivity increase Transparent location updates Transparent status updates Transparent incident information (updates) Transparent database queries =>quality & speed increase of the information exchange =>increase in productivity Statistics Reports =>better management Information exchange with others 15

16 HSD Workshop RF Coverage Analysis 6000 Coverage Analysis khz channels assuming TETRA 1 modulation/coding Range (metres) khz 50 khz 100 khz 150 khz TETRA Available bit rate [kb/s] MS 1W ERP; 2% BER: TU50; urban propagation 16

17 TEDS: Packet Data Throughput (Downlink kb/s) Modulation& Coding Rate Channel Type 25 khz 50 khz 100 khz 150 khz π/4 DQPSK, r = 2/ π/8 D8PSK, r = 2/ QAM, r =1/ QAM, r =1/ QAM, r =1/ QAM, r = 2/ QAM, r = Note: All channels are 4 slots 17

18 TEDS Advanced Operational Features Allows up to 8 multimedia applications. Allows QoS negotiation for: Real-time class data applications, voice and video. Telemetry class applications. Background class data applications. QoS attributes negotiated; throughput, delay, priority and reliability. Support for sectored cells. Allows use of existing TETRA1 Base Sites for TEDS without a need for additional sites. Enhances coverage for channels with higher modulations or bandwidths. 18

20 TETRA future data applications TETRA 2 is a fairly complete standard for PMR network for voice and data TETRA networks are still mainly used for voice TETRA needs to encourage/promote data application usage to deliver more return on investment for users TETRA 1 can support most mission critical applications needed today if they are properly designed TETRA 2 TEDS provides the data speeds needed for future (or non-properly) designed applications 20
