Sieci pracujące w standardzie 802.11, obok komórkowych, są obecnie najbardziej rozpowszechnionymi sieciami wykorzystującymi technologie bezprzewodowe. Ich popularność wynika z łatwej konfiguracji stanowisk ponieważ nie ma potrzeby układania okablowania, niskiej ceny urządzeń i pasm częstotliwości dostępnych dla wszystkich. Popularność skutkuje rosnącą liczbą sieci prywatnych i domowych, w których brak jest zarządzania zasobami częstotliwości. Prowadzi to w konsekwencji do wzajemnego zakłócania się sieci w standardzie 802.11 szczególnie w miejscach, w których występuje ich duże zagęszczenie. Większa świadomość użytkowników może pomóc w lepszym doborze lokalizacji urządzeń i właściwej selekcji kanałów wykorzystywanych do komunikacji.

The networks operating in the 802.11 standard, besides the mobile phone networks, are now the most frequent networks exploiting wireless technologies. Their popularity issues from an easy configuration of stations as there is no need to cable laying, low price of equipment and frequency bands accessible to all. The popularity leads to a growing number of private and home networks where there is no frequency resource management. In result, it leads to mutual interference of networks in the 802.11 standard, particularly in the places where there is high density thereof. Greater awareness of users may help in a better selection of location of equipment and a proper selection of the channels used for communication.

Using unique survey data on direct supplier-multinational linkages in Chile, Ghana, Kenya, Lesotho, Mozambique, Swaziland, and Vietnam, this paper first evaluates how foreign investors differ from domestic producers in terms of their potential to generate positive spillovers for local suppliers. It finds that foreign firms outperform domestic producers on several indicators, but have fewer linkages with the local economy and offer less supplier assistance, resulting in offsetting effects on the spillover potential. The paper also studies the relationship between foreign investor characteristics and linkages with the local economy as well as assistance extended to local suppliers. It finds that foreign investor characteristics matter for both. Additionally, this paper examines the role of suppliers’ absorptive capacities in determining the intensity of their linkages with multinationals. The results indicate that several supplier characteristics matter, but these effects also depend on the length of the supplier relationship. Finally, the paper assesses whether assistance or requirements from the multinational influence spillovers on suppliers. The results confirm the existence of positive effects of assistance (including technical audits, joint product development, and technology licensing) on foreign direct investment spillovers, while we find no evidence for demand effects.
