Super-E technology by u-blox – low power & high performance for wearables

Courtesy of u-blox Super‑E, developed by u-blox, is short for Super‑Efficient: Super-E is an intelligent power mode that reduces overall power consumption without impacting positioning performance. It uses only the minimal resources required for tracking and maintaining an accurate position, as opposed to the full‑power operation, which always tries to maximize positioning performance. https://www.u-blox.com/en/super-e-technology

Oslo, Norway 2017/12/11 As part of the lead customer-sampling program, Nordic has achieved its first approval for operation in live network of a leading cellular operator. Certification testing […]

Another technology sunset? The 3G sunset may be coming sooner than you think

Courtesy of Taoglas Today, device manufacturers developing IoT solutions face the choice of designing upon a variety of wireless technologies. However, it appears, just after the recent 2G sunset, that the 3G sunset in the US may not be too far behind. Carriers have differed in their approach to the transition from 3G to various […]
