Extending Macrocell Life

One of the ways the mobile world is trying to expand its reach and bandwidth is by moving to femtocells. Unlike macro-, micro-, and picocells, which remain outdoors and use the mobile backhaul infrastructure, femtocells typically plug into your home DSL or cable internet, completely bypassing the typical outdoor cellular infrastructure. Makes life easier for the carrier (and harder for the landline provider).

But Ubidyne has just announced active antenna technology that they say mitigates the need to change the cell structure: instead, operators can make better use of the cells they already have. They say that their beam-forming technology allows them to focus and direct the transmission energy in the direction most optimal for reaching the mobile handsets. The direction may vary by technology generation or other physical characteristics; this eliminates the need for making such adjustments using mechanical tilting.

They also claim that it reduces the amount of cabling as well as server sizing. Battery life is eased because of more efficient use of power – it’s going to where it’s needed more accurately.

Understanding Functional Safety FIT Base Failure Rate Estimates per IEC 62380 and SN 29500

Sponsored by Texas Instruments

Functional safety standards such as IEC 61508 and ISO 26262 require semiconductor device manufacturers to address both systematic and random hardware failures. Base failure rates (BFR) quantify the intrinsic reliability of the semiconductor component while operating under normal environmental conditions. Download our white paper which focuses on two widely accepted techniques to estimate the BFR for semiconductor components; estimates per IEC Technical Report 62380 and SN 29500 respectively.

Time Sensitive Networking for Industrial Automation

Sponsored by Mouser Electronics and Intel

In control applications with strict deterministic requirements, such as those found in automotive and industrial domains, Time Sensitive Networking offers a way to send time-critical traffic over a standard Ethernet infrastructure. This enables the convergence of all traffic classes and multiple applications in one network. In this episode of Chalk Talk, Amelia Dalton chats with Josh Levine of Intel and Patrick Loschmidt of TTTech about standards, specifications, and capabilities of time-sensitive networking (TSN).
