Company Philosophy

Global Wireless Technology (GWT), Inc., a private company, was founded in 2007. GWT has been developing innovative wireless technologies that challenge and advance the state-of-the-art in the wireless area. GWT improves the efficiency of existing wireless systems, including RFID and medical applications, while offering an attractive risk-free business approach for its customers. View more ++

GWT was a gold sponsor of the 2013 IEEE International Conference on Electro/Information Technology. GWT's founder, Dr. David Nghiem, was a keynote speaker for the conference. He gave a presentation on "Cell-phone: Issues & Solutions". GWT cares about the several billion cell-phone users around the world. GWT's mission is to help both the industry and the public by providing not only safe technologies but also reliable measurement techniques.

To improve system performance and reduce radiation, GWT has introduced a simple solution: GWT Wireless-Device Grip-Guide.

Dr. David Nghiem also gave the FDA a seminar on "Bluetooth Communication Systems for Medical Implant Applications" on July 15th, 2015. Bluetooth low-energy (BLE) technology has become a promising option for wireless medical implant applications. However, an increased body loss at the ISM frequencies utilized in a BLE communication system and common interference sources, including Wi-Fi, IoT, microwave ovens, etc. present challenges for medical implant applications. In the seminar, a Bluetooth medical implant system analysis was presented. System, interference, and MRI survivability & compatibility testing were discussed. A simple and reliable measurement/numerical modeling methodology that can be used to determine the conservative survivability/SAR/heating scenario was proposed. Dr. David Nghiem is also organizing the December 2015 IEEE MTT and EMC seminar on State-of-the-art Antenna Measurements for Wireless Medical Applications. View more ++
