The article presents the impact of remote work, resulting from the COVID-19 pandemic, on the functioning of Scrum teams. Attempts have been made to analyse the positive and negative aspects of remote work. The article also looks at the impact of remote work on the level of communication and efficiency of Scrum teams. For this purpose, the author conducted research on a sample of 40 organisations that declared to use Scrum methodology, using 187 questionnaires as the research material. The study was carried out at the turn of April and May 2021 and was carried out using the CAWI technique. The obtained results were analysed using the Principal Component Analysis and Cluster Analysis methods, and enable defining a picture of an organisation's readiness to work remotely. In addition, they also allowed for an assessment of how the infrastructure used for remote work communication translates into the organisation of Sprint meetings. This paper presents conclusions aimed at counteracting the observed irregularities detected during the tests. At the end, the author proposes solutions that could improve communication within Scrum teams, with remote work in mind.

Wybór kanału transmisji danych jest kwestię bardzo istotną w przypadku sieci wykorzystujących standard 802.11. Niezależnie od tego, czy standard służy do budowy sieci WLAN, Hot Spota lub jest wykorzystywany w transmisji kratowej, wybór kanału decyduje o uzyskanych parametrach QoS. Jednym z najpopularniejszych rozwiązań bezprzewodowych na świecie jest standard Wi-Fi. W zależ-ności od przyjętego kryterium można dokonać kilku jego klasyfikacji. W artykule omówiono podatność i odporność sieci na interferencje. Zaprezentowano także strukturę kanałów w pasmach 2.4, 5 i 60 GHz oraz metody selekcji kanałów. Przedstawiono także problemy i kierunki badań związanych z tematyką poruszaną w artykule.

The choice of the data transmission channel is a very important question in case of the networks using the 802.11 standard. Regardless of whether or not the standard serves the building WLAN, Hot Spot or is exploited in mesh transmission, the choice of the channel decides the achieved parameters of QoS. One of the most popular wireless solutions worldwide is the Wi-Fi standard. Depending on the adopted criterion, one may make several classifications thereof. In his article, the author discussed network’s susceptibility to and immunity against interferences. He also presented the structure of channels in the bands of 2.4, 5 and 60 GHz as well as the methods of channels selection. There are also presented the problems and directions of research connected with the subject matters discussed in the article.

The main point of view demonstrated in the present paper is to express criticism to those program of foreign language studies which still rely on the traditional approach to language education and favor the development of linguistic competence in students. Harmonious functioning of the contemporary world depends, to much extent, on human coexistence and communication both on the micro and macro scale. In the case of the macro scale contacts, the English language has been sanctioned an international means of communication. The examination of the Internet resources with reference to higher education language programs of studies as well as programs oered by some language schools, shows that the teaching/learning process is mainly concentrated on developing students' linguistic competence. The Polish reality of practical English application in a variety of situations shows that the language user's knowledge, when limited to the linguistic sphere only, is not sucient. Therefore, the aim of the present paper is to turn the reader's attention to the need of verication of educational policy, adopted by many higher education institutions, and expand the oered programs of studies by courses directing the teaching/learning process at the functional approach. Hence, the suggested in the present discussion approach would rely on giving priority to the development of communicative competence, instead of linguistic.
