  1. GPRS Network

  2. GPRS • IP over terrestrial wireless (cellular) • Frequency used depends on region • Twelve levels of performance (Classes) • Overlay on top of GSM voice network • GSM accessible by 29% of world’s population • But GPRS does not 100% overlap with GSM • Data shares network capacity with voice • Roaming fees apply to GPRS data General Packet Radio Service

  3. GPRS SIM • Billable entity for GSM/GPRS • Configured by GPRS service provider • ID number • Billing rate • Data, voice and/or SMS • Roaming allowed or not Subscriber Identity Module

  4. GPRS IP Network • Connects using Internet • IP address obtained from the network • Enables to-terminal messages • New address with each network login • Could change when crossing cells • IP sessions are used for billing • Kilobytes rounded up per session • IP resources time-out so they can be reused, causing session to drop

  5. GPRS Coverage The fine print… • Map depicts an approximation of outdoor coverage • Map may include areas served by unaffiliated carriers • Actual coverage area may differ substantially • Coverage may be affected by such things as terrain, weather, foliage, buildings and other construction, signal strength, customer equipment and other factors • Carrier does not guarantee coverage …this is a region where roaming is considered easy…

  6. GPRS Service Quality • ARPU driven by voice • Average Revenue per Unit • Key business indicator • Carrier business is selling quantity, not quality • Typical M2M unit revenue less than $10 per month • Increased usage is contrary to M2M business case • Voice and related services take priority Data Service Contribution to Carrier ARPU Voice services take priority for capacity use

  7. GPRS Roaming Example • Barge operator based in Hamburg • Shipping from Rotterdam to Austria • 7 days, report every hour = 168 reports • Follows 6 international borders • Cell signal switches network at least 6x based on signal strength • 50% transmissions “on-net” • 4 trips a month • Monthly GPRS Plan is 10 € for 5MB • Actual cost with roaming 32,04 € • Daily “off-net” surcharge 0,42 € per network (6+ networks) • Internet charges vary: • Austria, Netherlands each at 0,25 € • Belgium, France, Switzerland each at 0,69 € • WAP (2-way) adds even more 7 days x 0,42 = 2,94 € 2 network x 0,25 = 0,50 € 3 network x 0,69 = 2,07 € 5,51 € 10 € + 4 trips/month x 5,51 = 32,04 € 300% roaming surcharge and data use never exceeds plan (5 MB)

  8. When Deploying GPRS Consider… Risk What can de-risk GPRS deployment?

  9. GPRS Strength and Weakness

  10. GPRS vs D+ Coverage

  11. (Sources: GSM World, Inmarsat) SkyWave D+/GPRS Combined Coverage SkyWave D+ overlaid on GSM; GSM coverage indicated by orange shading • Best combination of reliable coverage and low cost • Security, safety & control data available at all times

  12. D+ Makes GPRS Better D+ • Global coverage • No charge roaming • Dependability • Reliability Benefits of the best of two worlds GPRS • Low cost air time • High data rate • IP network + Union of D+ and GPRS creates new opportunities and reduces carrier risks

  13. Expanding Business Opportunity GPRS SkyWave D+ • Marine • Waterways • Logistics • Dispatch • Land Mobile • Real-time tracking • Text messaging • Land Mobile • Tracking • Security • Control • Land Mobile • Logistics • Dispatch • Marine • Email • Internet • Fixed • Cathodic Protection • Remote Monitoring • Remote Control • Fixed with Backup • SCADA • Data logging • Marine • Tracking • Security • Monitoring • Fixed • SCADA • Data logging Leverage your expertise with SkyWave D+ to create new opportunities with GPRS

  14. Integration of D+ with GPRS • Lots of GPRS hardware available • Various capabilities and levels of quality • Integration of separate D+ and GPRS • Time consuming to integrate • Inefficient use of air time, server resources • Difficult to integrate • Example: Acknowledgement message

  15. SureLinx 8100 • The only integrated D+/GPRS • Lowest TCO • Transceiver and network services • Control station scalability, operation and maintenance • Significant operational improvements over other GPRS • Discreet in-cab unit & patch antennas • Flexibility • Customer not locked into specific set of keyboards, displays, sensors • Reliable, predictable, dependable networking • Simplifies networking to and from transceiver

  16. SureLinx 8100 5.9 in 5.0 in Height 1.5 in 5 m Max 10 m Max I/O, Power, data port D+/GPS Antenna GPRS Antenna D+/GPRS Integrated Access Device SkyWave SureLinx 8100 ideally suited for discreet land and marine applications

  17. Physical In-cab unit dimensions: 155mm x 125mm x 51mm Low profile satellite antenna: 93mm x 127mm x 23mm Environmental Operating Temperature Internal unit: -30 to +65C External antenna: -40 to +70C In-cab unit packaging IP40 / NEMA1 External antenna packaging IP66/NEMA4X Radio GPRS Module: Certified Module Quad-band GSM 850/900/1800/1900 MHz works in any country Class 12 GPRS multi-slot (depending on network up to 40 kbps) R&TTE, FCC, UL, GCF, PTCRB approvals Carrier approvals to be scheduled Inmarsat D+ modem Inmarsat type approved R&TTE, CE, FCC, IC (pending) Electrical Input voltage 9-40V Peak transmit draw 10W (10 second D+ burst) 30-pin JAE connector for power, serial & I/O FAKRA/SMB connector for low-profile satellite antenna SMA connector for GSM/GPRS antenna SureLinx 8100 Specifications

  18. Summary • GPRS is lots of cheap bandwidth, but: • GPRS roaming is not cheap • GPRS is unpredictable • D+ makes GPRS better • Lowers overall solution cost • Lowers air time cost • Broadens GPRS applicability (i.e. waterways) • Augments GPRS coverage • Reduces risk with GSM carriers
