GPRSGPRS
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

GPRS SIMGPRS 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

GPRS IP NetworkGPRS 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

GPRS CoverageGPRS 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…

GPRS Service QualityGPRS 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 priorityVoice services take
priority for capacity use
Data Service Contribution to Carrier ARPU

GPRS Roaming Example 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)

When Deploying GPRS When Deploying GPRS Consider…Consider…
Question Alternatives
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

GPRS Strength and GPRS Strength and WeaknessWeakness
Strengths Weakness
Low cost air time Terrestrial and populated areas
Global roaming Expensive, unpredictable
Limited by SIM configuration
High data rate Best-effort – no guaranteed data rate Unpredictable performance
Impacted by voice congestion
Low cost terminal Broad range of products• Class, slots• Single band vs Quad band• Quality and robustness
Supported by large carriers Focus is voice

GPRS vs D+ CoverageGPRS vs D+ Coverage
GPRS SkyWave D+
Accessible by 29% of world’s population
Global coverage between +/- 75° latitude
Terrestrial populated areas Land, 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 traffic Dedicated data network

Integration of D+ with GPRSIntegration 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

SummarySummary
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
