Historical Research Background:

IS-Wireless was founded in February 2006 by Dr. Slawomir Pietrzyk and a small team of wireless experts and business managers. The company creation was a natural consequence of Slawomir’s work on OFDMA, which started under the supervision of Prof. Ramjee Prasad in 1998 within the Ubiquitous Communications (UbiCom) Project at the Delft University of Technology (TUDelft) in the Netherlands.

Slawomir’s research resulted in a PhD thesis entitled “Radio Resource Management for Orthogonal Frequency Division Multiple Access Systems”, defended at TUDelft and the book entitled “OFDMA for Broadband Wireless Access” published by Artech House in 2006.


From the very beginning the company was working around OFDMA-based radio interfaces, first non-standard proprietary and then standard ones including mobile WiMAX and LTE, later focusing on 5G.
