Objectives

Effects on mobile (GSM) phones:

• Unable to initiate calls or SMS messages

• Unable to receive calls or SMS messages

• Unable to transmit any radio signal

• Disconnect call upon entering covered area

Principle of Operation• BlockPhone transmits radio signals at the

frequency band used for cellular base station transmission

• Mobile phones within coverage area are unable to decode base station signals

• Mobile phones switch to NO SERVICE mode

Performance Considerations

• Effective operating range depends mainly on the signal strength received from nearby cellular base-stations

• The closer the base station, the lower the operating range

• The higher the power generated by BlockPhone, the longer the operating range

Safety Concerns

• Low power: 30 cm from humans• High power: 3 m from humans (permanent exposure)

According to the guidelines set out by the International Radiation Protection Association (IRPA), BlockPhone is safe for use under the following conditions:

Reliability

• SMT assembly

• 12 months warranty

• Software built-in test

Customization

• BlockPhone is a modular system that can be customized to a variety of systems

• Wide range of antennas for optimized coverage

• Location specific calibration can be applied to provide high performance
