Jan Kåll

Jan Kåll started working on mobile communications in 1982 specifying system simulators and base stations for the Nordic Mobile Telephone (NMT) system. He was also involved in the early days of GSM specifying the GSM system simulator for testing mobile terminals in the SMG Permanent Nucleus in Paris (similar to 3GPP-MCC) 1986-88. Currently located in Espoo, Finland and with Nokia and Nokia Siemens Networks since 1997. Before 1997 Jan was working for TeliaSonera’s roaming services and in international operator projects.

In the early 2000s he was the chairman of 3GPP SA2 subgroup for location services, which also served emergency services. He worked on the OMA Enabler Release for IMS and IMS emergency services in the 3GPP. Now, Jan is active in the 3GPP CT4 and CT1 working groups dealing with local switching and non-3GPP access technologies, such as ANDSF, WLAN, PMIP and AAA server interfaces.

Byron L. Smith

Mr. Byron Smith has recently retired from more than 40 years of work in computer software development, peripheral hardware development, IP networking, college-level teaching, data network engineer, 9-1-1 systems engineer, NG-9-1-1 network architect, and consultant. Early in his career he developed hardware and software to construct a gamma-ray spectrometer for a university laboratory. He later taught mathematics and computer science at the undergraduate level.

In the past 20 years he has engineered LAN and WAN networks for telecommunications customers, served as a regional public safety product manager for a major telephone company, designed and supervised the installation of a statewide NG-9-1-1 ESInet, and written specifications for statewide NG9-1-1 networks for several US states.

Since 1992 he has been engaged in various technical aspects of public safety and 9-1-1, including database management software and processes, selective routing development, PSAP CPE design and implementation, and 9 1 1 network design and implementation using analog, TDM, and IP technologies.
Mr. Smith has dealt with a full range of 9-1-1 systems, products, vendors, and interoperability issues. One of Mr. Smith’s greatest assets has been his ability to develop protocol and interface conversion systems that permit public safety systems from various technologies and protocols to work together for the public welfare.
