OEM wireless card is
complete RF front end

Coronis Systems is extending its current Wavenis wireless technology product line with a novel solution called the Wavefront

The Wavefront is a tiny OEM wireless card and is the first ultra-low-power solution on the market to provide a ready-to-use RF chipset (front-end) in which the controlling protocol software actually runs on a target device's separate, existing microcontroller. This solution offers savings often associated with single-chip devices that use a single microcontroller for communications and radio functions.

At the same time, it saves the developers time in that they can continue using their existing microcontroller for their own applications (plus the Wavenis protocol), and add wireless features easily by connecting the Wavefront RF board.

The card meets integrators' requirements that wish to enhance their applications with specific new communication features without having to develop radio-frequency solutions themselves.

By being able to concentrate on their core business, integrators benefit from both smart new radio equipment and fast time-to-market.

Wavefront is a front-end radio board designed to provide datacommunications in ultra-low-power products.

With this new product, a target device's existing microcontroller runs its own firmware applications as well as the Wavenis protocol stack to control the Wavefront addon.

This unique solution keeps production costs down by only requiring a single microcontroller, offering customers a ready-to-use, industrial quality RF card that is controlled by a simple serial bus.

The Wavefront card is an ideal solution for integrators with product volumes up to around 50,000 units.

The kit comes with a software-programming tool to help interface custom applications with the Wavenis communication protocol's software layers.

The tool also makes it easy to customise communication features according to specific needs.

With its ultralow power (ULP) consumption and long-range performance, Wavenis is frequently used in heterogeneous networks alongside Bluetooth and Wi-Fi protocols.

It was developed to optimise the performance/price ratio from integrated circuit design through industrialisation.

In its Wavenis Embedded Technology line, Coronis Systems offers two other products - fully integrated Wavecard modems, and Wavenis technology licensing.

Over 250,000 Wavenis powered products have been shipped to-date.

With the Wavenis platform, which includes the ultra-low-power RF transceiver and complete wireless protocol stack, Coronis offers system integrators and OEMs a total solution.

Highly sophisticated mechanisms such as frequency hopping spread spectrum (FHSS), data interleaving and forward error correction (FEC) give Wavenis the ability to stand up to interference (with no increase in power consumption) and allow it to be used simultaneously with other RF technologies.

Wavenis technology may be used with any stand-alone device that requires wireless connection within ISM (industry-scientific-medical) frequencies.

Wavenis uses the 868MHz (Europe), 915MHz (US) and 433MHz (Asia) frequencies and offers all of the functions needed to create wireless mesh networks with point-to-point, broadcast, polling, and repeater functions.

Target applications typically have very low volumes of data to transfer.

However, they also require ultralong battery life and typically require radio coverage under difficult propagation conditions (difficult radio access, weak radio signals inside buildings, weak antennae due to integration requirements etc).

With Wavenis technology, even for the most critical applications, battery life can reach up to 15 years.

Additionally, the 124dB dynamic RF link offers operational power consumption of 10uA with a range of 1 km in line-of-sight (LOS) and 200m indoors.

Wavenis wireless technology is particularly well-adapted for products and applications in home comfort, centralised building access and remote control (lighting, HVAC, doors and windows), alarms, security, remote meter reading, healthcare, tracking (locating items and people; UHF RFID), and general consumer goods (such as weather stations and smart objects).
