Embedded Wireless White Papers

Latest Embedded Wireless White Papers: 

Tlam OptoTEC

Laird's OptoTEC series of miniature thermoelectric modules (TEMs) is made using Laird Tlam circuit boards instead of traditional ceramic-based circuit boards. All TEMs consist of pellets of semiconductor material soldered between two circuit board substrates. Tlam is a laminated circuit board product capable of transporting heat to and from the semiconductor pellets while providing excellent heat spreading, improved reliability and low cost in high volume. This white paper discusses the performance, reliability, advantages and limitations of OptoTEC TEMs made using Tlam in addition to describing other new products using Tlam that are currently in development.

802.11n and Medical Devices

With throughput much greater than that available with previous wireless local area networking (WLAN) standards, the IEEE 802.11n standard has had a significant impact on the WLAN, or Wi-Fi, industry. Most of today’s WLAN infrastructure products support 802.11n, and support on client devices is growing.

Putting 802.11n on laptops and other general-purpose client devices makes sense if those devices need a throughput boost. Most medical devices don’t need higher throughput. Because those devices may be used for five years or longer, consider dual-band 802.11n for them now if you can get it for a modest price premium.

Understanding Range for RF Devices

Understanding how environmental factors can affect range is one of the key aspects to deploying a radio frequency (RF) solution. This paper will provide a high-level overview of the factors that can affect RF range, including hardware selection, environmental factors, frequency ranges, and proper implementation.

Whether you are looking to connect across 10 meters in a crowded hall or 10 kilometers outdoors, the environment plays a significant role in the maximum range that can be achieved. This white paper explains how range numbers are calculated and discusses the factors that limit range.

The Value of Cisco Compatible Extensions (CCX) for Rugged Mobile Computers

IEEE and industry standards define how a Wi-Fi radio interoperates with a wireless LAN infrastructure, and the Wi-Fi CERTIFIED™ seal ensures interoperability. For many organizations that rely on mobile computers, however, Wi-Fi CERTIFIED is not enough. These organizations need assurance that their mobile computers will interoperate with a Cisco wireless LAN infrastructure and support Cisco wireless LAN innovations for enhanced security, mobility, quality of service, and network management. The Cisco Compatible seal gives organizations the assurance that they seek.
