Remote Patient Monitoring and

Health Care

The success of CardioNets solution has driven a host

of other remote patient monitoring solution providers

into the market

Consumer Telematics

DriveCam has helped save lives & reduce teendriving collisions by 70%

Digital Payment Technologies

Many parking operators report a very short cycle for

return on their investment typically 12-15 months

Remotely Monitor Dispersed Assets

Re-moving the need to send personnel to checkup on

distant assets and infrastructure

Logging, Mining, Oil & Gas Reporting

Reduced Truck Rolls

On average, the SmartTrash system saves

customers between 25 to 70% on waste

management costs

People and Asset Monitoring

800k children go missing in the US each year, over 5M elderly

adults are suffering from Alzheimers/dementia

Track high-value mobile assets including bank bags, laptops,

vehicles & retail goods whether they are indoors, outdoors,

traveling or at a fixed location.

E-Readers

Eliminate ~50% of publishers

operational expenditures.

Smart Grid

Tatas CDMA2000 solution downloads datain 6-8 hours, previous solution took 4-5days

to make the same data available

Sea transport & ship ping

Companies need costal coverage with an

increasing demand for high data speed Fishing, Passenger, Leisure, Freight

Lower power consumption + excellent coverage Increases in total addressable market (TAM) Reduces cost for a target battery life

Higher connection capacity Enables operators to support more direct cellular

m2m nodes with a given amount of network resource

Solution cost Module cost is just a component; Network + Service + Maintenance cost are critical



6/33

Promote use of existing technologies (andleverage coverage + network)

Enhance the air-interface to improve batterylife and connection capacity

Evolve network architecture



7/33

Battery Life

Congestion and Overload Control

Efficient handling of infrequent data transfers

m2m server and network control of m2m client

Fast re-authentication



8/33

Communication w/ m2m devices without an IP address

An external m2m device identifier

Group addressing, communication, and billing

Efficient test and certification processes

1x air-interface is optimized for low-rate

(voice, data) communications and 1xdeployments (at 800MHz or below) haveexcellent coverage

Most m2m apps are characterized bylow-rate data and require good linkbudget

1x offers a cost-effective solution to meet

the needs of a large portion of m2mapplications
