RayMarine, a world leader in marine electronics, develops and manufactures the most comprehensive range of electronic equipment for the recreational boating and light commercial marine markets. The Raymarine e7 Network Multifunction Display breaks new ground with Wi-Fi video streaming to Apple iPhones and iPads or Android Tables and Smartphones. Additionally the e7’s built-in Wi-Fi adapter allows it to wirelessly sync waypoints and routes with the Navionics Mobile app. This enables you to plan your next voyage on your iPhone or iPad and then wirelessly sync it to the e7’s chartplotter.


The Technical Challenge

High performance Wi-Fi was essential for the e7 device to interoperate with today’s leading smartphones for streaming video. The device also required Bluetooth to stream music and audio control directly from the smartphone to the display. This coupled with the challenging environment demanded a robust radio solution that could withstand various interferers at extreme temperatures.

The Solution

The e7 platform is based on LSR’s TiWi-R2 module. The FCC/IC and ETSI tested module is based on the WL1271 solution from Texas Instruments and supports 802.11 b/g/n and Bluetooth 2.1+EDR. The fully integrated module provided a fast time to market and easy to implement solution. The TiWi-R2 boasts best in class performance (4dB better link margin than competition) in a footprint smaller than a penny (13mmx19mm). LSR strategically designed the module to include an analogue front end and TCXO for superior range performance at industrial temperatures. Raymarine took advantage of LSR’s flexible antenna solutions and implemented a printed circuit board trace antenna to fit within the slim profile of the e7 while still offering advanced performance.

LSR offers:

  • Experience in leveraging wireless in an industrial setting, including evaluating potential interferers and demanding environmental factors
  • Custom antenna design and driver integration with various operating systems and microprocessors, including QNX, Linux, and Android
  • Development of Wi-Fi, Bluetooth, 6LoWPAN, BLE, and other standards-based wireless products
  • Custom protocol development to meet your application’s unique needs

Danfoss Power Electronics

Danfoss Power Electronics designs and manufactures inverters and power conversion equipment for industrial applications that requir anywhere from 90kW to multi-mega watt solutions.  They  recently joined forces with LS Research to perform a series of EMC Tests to qualify their latest Programmable Motor Drive Systems for the global market. These drives range from  90kW to 560kW. 

“LS Research had the expertise to provide support and consulting during the development stage of the test plan and they accommodated the highly compressed test scheduling needs for Danfoss.  LS Research was able to maximize the available calendar time and gain turn-around efficiencies by performing tests on our samples for continuous 16 hour sessions.

LS Research has a team that is technically qualified, experienced, and very ‘tight’ as a group. They work well with each other.  Their data handling and communication processes are second to none.  I routinely had draft reports, ready for review on the same day the test was performed. This allowed for a very quick turnaround in generating the final reports to support our targeted completion dates.”

-Abtin Spantman, RF/EMC Engineer, Danfoss Power Electronics

The Technical Challenge

Qualifying the family of products required numerous configurations to be tested, along with multiple operating modes and various available options to fully evaluate the end-product offering.  LS Research was selected by Danfoss to test the latest Motor Drive System because of LS Research’s capability, accreditations, reputation and experience in testing motor drives.

The Solution

For over 20 years LS Research has been providing compliance expertise to industrial markets assisting in the investigation of appropriate test standards, test plan development, troubleshooting/failure analysis, documentation review, and testing for EMC,  FCC, Industry Canada, European Union, Australia, Japan, South America and other international countries certifications.  As an FCC listed and Industry Canada recognized test site and Conformity Assessment Notified Body for the EMC and R&TTE Directive, with an ISO 1025 Accredited Test Laboratory, LS Research brings both the knowledge and toolsets required for a successful compliance testing engagement. 

LS Research offers:

  • Extensive Experience in Industrial Product Testing
  • 3m Semi-Anechoic Chamber
  • 10m OATS (Open Air Test Site)
  • EMC Emissions and Immunity Specific Test Equipment
