The Emerging Implications of Wireless Coexistence on Modern Medical Environments
Join us for this free webinar jointly sponsored by several IEEE EMC Society Chapters and the ANSI C63 committee. The topic addresses the ANSI C63.27 standard on coexistence as related to medical environments. All IEEE members and guests are welcome to attend, but you must register in advance at https://attendee.gotowebinar.com/register/6172753247267297806.
Following the presentations by the ANSI C63 members shown below, James Young of ETS-Lindgren will discuss Verifying Coexistence Performance – A Review of Test Methods and Environments specified in ANSI C63.27. Four measurement methods for coexistence testing are specified in ANSI C63.27: 1) conducted, 2) multiple chamber, 3) radiated anechoic chamber, and 4) radiated open environment. Conducted and open environment test methods will yield valuable information, but advanced wireless technologies like 802.11 n, Bluetooth Low Energy and 5G will likely require shielded anechoic test methods for repeatability and accuracy. Anechoic test methods are necessary when measuring MIMO antenna impact and spectrum sharing technologies which may be present in commercially available wireless modules. A review of each of the four coexistence test methods and measurement results that can be expected from each will be explored in this presentation.
After the three presentations, Dan Hoolihan, Chair of the ANSI C63 Committee, will moderate a Q&A session with all speakers.

Wireless Coexistence: What is It?
Abstract: Wireless coexistence is a formidable problem that limits access and use of spectrum in today’s connected world. End-users, system administrators, network planners, and regulators all desire to understand how their wireless devices, systems, or networks will perform amid many other wireless devices before they are deployed. Given this desire, how can we design tests that quantify a device’s ability to coexist? To start, can we pin down what quantities represent good wireless performance? How should test results be interpreted? This talk will present an overview of the concept of wireless coexistence in general and outline some of the challenges facing the community. The goal of this talk is to leave audience members with a better understanding of what coexistence is (or isn’t) and a deeper understanding of how we can tackle coexistence problems to enable better access to spectrum.

Medical Device Wireless Coexistence Evaluation Framework
Abstract: Wireless coexistence evaluation is recommended in the FDA guidance document on radio frequency wireless technology in medical devices. The coexistence evaluation framework includes two FDA-recognized documents: AAMI TIR69 Technical Information Report “Risk management of radio-frequency wireless coexistence for medical devices and systems” and ANSI C63.27 “American National Standard for Evaluation of Wireless Coexistence”. This presentation will provide a narrative for addressing wireless coexistence in medical devices. The discussion will cover the relationship between the specified medical device wireless function risk category and the test evaluation tier, specification of the device functional wireless performance (FWP), testing, and reporting test results.
