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


SkyWave D+/GPRS Combined CoverageSkyWave D+/GPRS Combined Coverage

• Best combination of reliable coverage and low cost• Security, safety & control data available at all times

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
