4 29 Aug 2005 Teamed with Ericsson now MTAB Targets Higher integration Less components Reduced weight Smaller modem Easier to design 4

5 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

6 Overview Mobitex application value proposition Improve cost/benefit to enable new business Advanced terminal technology 6

7 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

8 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

9 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

10 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

11 Where to change cost/benefit? Base Base Base Base Base Base Application Server Mobitex Network Control Center = Mobitex terminal 11

12 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

13 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

14 Easier said than done Mobitex terminal anatomy RF Codecs Type of Work Performed Signal processing Digital processing Sof tware Radio Transceiv er DACs ADCs Baseband signal processing Low lev el packet protocol High lev el packet protocol User application program Aux I/O Fast control Aux DAC Monitor & Control slow Aux I/O RF ICs Conv erter ICs Mobitex ASSP IC or DSP IC + software (ROM IC) + uc IC + software (ROM IC) What does the work? Host uc IC + software (ROM IC) 14

15 CMX990 functional footprint CML & Ericsson (now MTAB) worked together RF Codecs Type of Work Performed Signal processing Digital processing Sof tware Radio Transceiver DACs ADCs Baseband signal processing Low lev el packet protocol High level packet protocol User application program Aux I/O Fast control Aux DAC Monitor & Control slow Aux I/O RF ICs Conv erter ICs Mobitex ASSP IC or DSP IC + sof tware (ROM IC) + uc IC + sof tware (ROM IC) What does the work?
