  - TASK Quarterly - Year 2018

  The LoRaWAN Technology opens new possibilities for gathering and analysis of distributed data. In the paper we concentrate on its maritime usability which was tested by us in the period from June to August 2018. Measurements of the LoRaWAN network coverage in the Bay of Gdansk area were carried out. Various conditions and places were tested. The research was planned in such a way as to gradually increase the range and control the...

  Internet of Things devices that send small amounts of data do not need high bit rates as it is the range that is more crucial for them. The use of popular, unlicensed 2.4 GHz and 5 GHz bands is fairly legally enforced (transmission power above power limits cannot be increased). In addition, waves of this length are very diffiult to propagate under field conditions (e.g. in urban areas). The market response to these needs are the...

  - TASK Quarterly - Year 2015

  Multimedia stream processing into two cooperative different systems (cluster platform and virtual lab) is considered. The considered selected information about the systems is presented and the idea of its communication when executing the distributed application is proposed. A general schema of the communication architecture is given. Tests of data transmission quality are considered and their results are presented.

  Management of user at the network layer plays an important role in efficient network operation. In the paper, authors' implementation of one of network-based mobility management models, namely Proxy Mobile IPv6, is presented and tested in a number of networking topologies and communication scenarios. The proposed implementation covers PMPIv6 functionality with optional security extensions (use of Diameter protocol) and handover...

  W ramach realizacji projektu budowy linii kolejowej pomiędzy Centrum a Lotniskiem Gdańsk Rębiechowo przez spółkę "Pomorska Kolej Metropolitalna S.A", postanowiono zbadać techniczne możliwości udostępnienia Internetu pasażerom na czas podróży. Celem opisanych badań było przetestowanie, w warunkach rzeczywistego ruchu pociągów, możliwości zapewnienia dostępu do Internetu dla pasażerów publicznej komunikacji kolejowej przy zastosowaniu...
