Ionocom Communications Inc

Wireless Design

A particular focus for Ionocom is design of wireless products, using our broad experience over a wide range of technologies and frequency bands, with emphasis on short-range communications.

13.56MHz RFID
We have designed several products using the 13.56MHz RFID band, including active asset tracking systems and a multi-antenna tag reader for passive tags.

88-108MHz Broadcast FM
We have designed several low-power licence-exempt FM transmitter products for use with portable music players. In addition to stereo audio we have designed products that transmit RDS data.

433MHz Proprietary Short-Range Devices
We have designed many products using the common 433MHz ISM band for short-range communication. Our experience includes systems with antenna and frequency diversity.

850-2100MHz Cellular
We have designed products including cellular voice and data functionality, using solutions from suppliers such as MultiTech, Wavecom and Qualcomm, in all of the major North American frequency bands, on CDMA and GSM networks.

1575MHz GPS
We have designed products with GPS receivers from suppliers such as Telit, Qualcomm and Ublox. Products have included gyroscopes and other methods to enhance location performance. We have used both patch and helical antennas.

2.4GHz ZigBee
We have designed ZigBee radios into products to provide wireless data transfer, using modular solutions and also discrete component designs based on chips from Ember Corp. Our work has included firmware as well as hardware, and we are familiar with the ZigBee stack.

2.4GHz Bluetooth
We have designed Bluetooth links into products to provide wireless data transfer, using modules from companies including Free2Move and National Semiconductor. We have also dealt directly with chip supplier Cambridge Silicon Radio. Ionocom is an Adopter Member of the Bluetooth SIG and as such has access to all the latest standards and specifications.

2.4GHz Proprietary Short-Range Devices
We have designed many products using proprietary protocols in the 2.4GHz ISM band, typically using chips from Nordic Semiconductor. Projects have ranged from parking management systems through wireless mice and keyboards to iPhone accessories.

We also have experience with other systems and frequencies ranging from shortwave (3-30MHz) through VHF and UHF to radar (5GHz).

In all these frequency bands we can select and design-in off-the-shelf antenna solutions. We have used monopoles, dipoles, loops, patch, helical and PIFA solutions. We also have the capability to design, model and simulate custom wire and planar (PCB trace) antennas for low-cost applications.

Ionocom has a variety of RF engineering design software available including SPICE, HP Touchstone, NEC-Win, EZNEC and Sonnet.
