County District Attorney's Office, LOCAID, Nextel (Sprint), NAVTEQ (HERE), Qualcomm, Peschke, Samsung, Toyota, Twilio, Verizon Wireless, Vivint, and XYVerify.
Mr. Williams has developed and implemented industry-leading product and technology solutions for numerous LBS and IoT applications and markets and provides consulting and research services to some of the leading carriers and enterprises in the U.S., Asia, and Europe. He has provided testimony, consulting research, technical expertise and advisory services in over 100 Intellectual Property/Patent, Location Forensic, ITC, and Anti-Trust litigations/cases.
With over thirty years in location, communications and information technology solutions design, selection, implementation and ongoing management, Mr. Williams has extensive experience in the activities and issues needed to get applications to market, including planning and design at the application, system, interface/integration, network, IT, operational and customer facing levels. He has been published and quoted by leading magazines and newspapers about location-related services, including The New York Times, CBS News.com, The Columbus (Ohio) Dispatch, The Boston Globe, Computerworld, Directions Magazine, Mission Critical Communications, Popular Mechanics, and RFID Journal.
Mr. Williams has authored five books on wireless location, including The Definitive Guide To RFID, Wi-Fi, Bluetooth Low Energy (BLE), UWB, Ultrasound, Infrared, and Other RTLS and Beacon Technologies (available October 2018),The Definitive Guide to GPS, RFID, Wi-Fi, and Other Wireless Location-Based Services (two versions), The Definitive Guide to Wireless E911, and (co-authored) The Definitive Guide to Mobile Positioning and Location Management.Mr. Williams has authored dozens of research reports, and tracks and analyzes leading companies in the LBS, IoT, and public safety industries particularly with respect to their product and technology strategies, competitive capabilities and implementation issues. He is expert on all public policy and technology issues related to emergency services/public safety, location data privacy and security, and LBS and IoT privacy protection policies, systems, and support infrastructure.
Wireless 911(also known as E911, or Enhanced 911) is the technology that allows emergency dispatchers know the location of 911 calls coming from cell phones. This technology has been rolled out in the U.S. by wireless carriers under a mandate by the Federal Communications Commission, and is being persued in other countries as well.
While obviously a desireable technology, particularly in today's security-concious environment, the rate at which this technology is fully adopted is dependent upon many factors, including carrier technology, regulatory deadlines, PSAP (Public Safety Answering Point) readiness, funding and cost-recovery mechanisms, and many others. The accuracy and utility of 911-type services is dependent upon the location determination technology employed by a carrier during an emergency call, as well as the capabilities of the emergency responder to utilize the location information associated with that call.
The late 1990s U.S. mandate by the FCC have essentially been fully met; key parties are now exploring the potential of Next Generation 911 (NG911) to accomodate the additional types of emergency-related information now widely available (e.g. text, video) and greatly improve interoperability between various types and location of first responders and another emergency entities. In addition, a new (2015) mandate by the FCC improves/increases accuracy requirements that has put new focus on indoor location technologies in particular.
Location-Based Services (LBS)are the commercialization of location determination technologies such as GPS via applications that provide additional value-add to consumers, such as navigation services, finding the location of friends and family, and searching for local landmarks and services. For businesses, it includes such services as mobile field force management for managing field workers such as repair technicians and sales persons; fleet managment applications for mananging trucking and delivery services; and mobile asset management to track and manage mobile assets ranging from railroad cars to hospital equipment.
The value-add for LBS applications can include convenience, peace-of-mind, entertainment, networking/personal connectivity, productivity improvement, cost reduction, and revenue enhancment among many others. The uses of location services are almost limitless: if someone or something moves in the context of seeing, using, or doing something, then an LBS app can nearly always be developed to help.
While there are many issues associated with the development and deployment of location-based services, the largest one that remains unresolved is the protection of location information. There is currently little in the way of regulations or case law that determines how location information can be collected and used, so it is up to individual companies to determine how they want to protect and utilize that information. This is resulting in a wide variety of location data privacy policies and practices, most trending towards collecting and using this information in whatever way possible, and away from ensuring the protection of that personal location information.
