Custom Wireless 802.15.4 Transceivers

Design Note #79

Custom Wireless 802.15.4 Transceivers

Custom wireless 802.15.4 transceivers from OTEC operate in the 900MHz, and 2.4GHz frequency bands. Occupying 802.15.4 channels 1 through 27, wireless communications on these frequencies can be very useful for low bandwidth data telemetry. IEEE 802.15.4 specifies a means of wireless data transmission. Application requirements can dictate actual data transmission protocols used. OTEC has developed protocol variations for beacon enabled and non-beacon enabled networks.

Extended Battery Life

Lithium-ion and Lithium-polymer batteries provide high energy in small lightweight packages. Four hours of serviceable operation requires careful energy management. Dynamic power control, firmware power monitoring and power load management achieve extended operating times.

GPS Receiver Subsystem

Close proximity of the GPS receiver, 802.15.4 transceiver, and digital microcontroller signals required careful circuit floor planning. Careful circuit routing, shielding and planning maximizes radio link performance while managing subsystem interference.

Physically Thin Packaging

Build upon a 1mm thick circuit board, component parts where chosen for both their electrical performance and their physically small size. Close cooperation between industrial design and electronic design made this physically thin package a reality.

Rapid Wireless Radio Design Cycle

Product trials were already scheduled when we began. OTEC had to deliver working units in eight weeks. Combining industrial design, electronic design and component engineering, OTEC crafted a rugged data collection device in record time.
