Enabling Asset Security & Management GPRS Network

Enabling Asset Security & Management GPRSN P 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

Enabling Asset Security & Management GPRSN P 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

Enabling Asset Security & Management GPRSN P 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

Enabling Asset Security & Management GPRSN P 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…

Enabling Asset Security & Management GPRSN P 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 Voice services take priority for capacity use Data Service Contribution to Carrier ARPU

Enabling Asset Security & Management GPRSN P 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)

Enabling Asset Security & Management GPRSN P 8 When Deploying GPRS Consider… QuestionAlternatives Which frequency bands?850/1900 MHz or 900/1800 MHz; quad band modems cover all What class of GPRS?1 (lo speed) to 12 (hi speed); class 10 and 12 offer best flexibility Will coverage be available?Dependent on carriers Will there be coverage when it’s needed?Dependent on network load What will roaming cost?Dependent on carriers Will my modem be allowed to roam?Dependent on carriers Will my business case support roaming?Dependent on carriers Will performance be consistent?Dependent on carriers Is usage rounded-up & metered by time?Dependent on carriers What can de-risk GPRS deployment? Risk

Enabling Asset Security & Management GPRSN P 10 GPRS vs D+ Coverage GPRSSkyWave D+ Accessible by 29% of world’s population Global coverage between +/- 75° latitude Terrestrial populated areasLand, sea or air Designed for Internet access – best effort Designed for monitoring and control – high availability Roaming occurs with varying charges and sometimes requires manual intervention Roaming without any additional charge and is automatic Enabling roaming can increase cost even if not roaming No additional cost for roaming Impacted by voice trafficDedicated data network

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

Enabling Asset Security & Management GPRSN P 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
