29 Aug 2005 Teamed with Ericsson now MTAB Targets Higher integration Less components Reduced weight Smaller modem Easier to design 4
CML Microcircuits perspective 35 years as a focused manufacturer of analog/digital, wireless/wireline communication ICs Provide ICs to enable Mobitex terminals Three generations of focused Mobitex wireless data ICs over the past 10 years CML is an enabler 5
Overview Mobitex application value proposition Improve cost/benefit to enable new business Advanced terminal technology 6
The user value proposition User cost/benefit drives Mobitex-based business Users buy solutions, not just Mobitex Solution = User app + wireless comm services + terminals User value comes from benefits vs. cost 7
Enable new business The sweet spot Cost Reduce Increase Benefit Increase Reduce More for less Less for less More for more Less for more 8
User Benefits Save time = save $ M2M Service/fleet logistics Diagnostics Telemetry/control etc. People Mobile business communications Spend time make people feel good Connect with friends & family Entertainment 9
User Costs tangible/intangible Network services Usage fees Performance (proven excellent) Terminal cost Design effort Components Terminal installation and operation Size, weight, power (battery life/size), performance, convenience, style Terminal/user application Software Hardware e.g. sensor I/O etc. DynaTAC8000x 2 lbs / 0.8kg 30 minutes battery charge 10
Where to change cost/benefit? Base Base Base Base Base Base Application Server Mobitex Network Control Center = Mobitex terminal 11
Where to change cost/benefit? Network services Usage fees Performance (proven excellent) Terminal cost Design effort Components Terminal installation and operation Size, weight, power (battery life/size), performance, convenience, style Terminal/user application Software Hardware e.g. sensor I/O etc. 12
Increase terminal integration Reduce Hit the cost/benefit sweet spot Cost Significantly lower cost Components Significantly smaller terminal Size Weight Design effort Complexity, risk and time Improve User convenience Battery life Reliability 13
