Please find attached the latest version of Ultra Low Power Wireless Q. Integra Systems, Inc., has worked with Nordic in the past for product development of a medical device using ANT. We are in current product development with our partner on a unique Bluetooth 4.0 solution coupled to an I-Phone application. Bluetooth 5.0 is now being introduced (pages 16 &17). Open cellular standards now supporting Low Power Long Term evolution. Low Power LTE operates in up to 44 different licensed frequencies across the world, ranging from 450 MHz to 2.6 GHz. The advantages of licensed spectrum are particularly beneficial for many IoT applications; key among these are that the owners of the spectrum allocation (the carriers) can control and prioritize data, and the bands are immune from interference from other sources of RF radiation. Second because that the spectrum allocation is not shared with other RF transmissions, coexistence between connected devices is much easier to manage. LTE's coexistence technology is based on proven time-domain solutions, and other mechanisms such as autonomous denial of conflicting RF signals. LTE's coexistence mechanisms will allow a single base station (tower) to support up to 200,000 low power modems. LTE infrastructure is largely in place in 157 countries with over 380 networks.
