List of assignments UNIK4700:Assignments
Disclaimer: This compendium provides information on aspects of radio wave propagation, antennas, system aspects, and handover schemes for mobile and wireless systems. The compendium is foreseen for the UNIK4700 course on Building Mobile and Wireless Networks, and is kept on the system aspects level. UNIK has several courses on Radio and Network technologies as part of the Wireless Networks and Security (WNaS) research area.
Note: 802.11 is sending with different speeds for header and payload. Header is always transmitted at lowest speed, why?
Hertz did not realise the practical importance of his experiments. He stated that,
"It's of no use whatsoever[...] this is just an experiment that proves Maestro Maxwell was right - we just have these mysterious electromagnetic waves that we cannot see with the naked eye. But they are there." [3]
Asked about the ramifications of his discoveries, Hertz replied, "Nothing, I guess." [3]

Note:
G. Fettweis has focus on radio technology, not on applications and "costs" for usage. In the application area, NFC is a replacement of contactless cards for payment, using the same security mechanisms. With respect to "sensor networks" and low energy consumption, the limitations to UWB+ will not fulfil those needs.
Focus on three communication areas
