DSSs allow for more informed decision-making, timely problem-solving, and improved efficiency in dealing with issues or operations, planning, and even management. How Decision Support Systems (DSSs) Work A decision support system is a computer program that gathers and analyzes data. This information...
IEEE 802.11a (the first standard to be ratified, but just now being widely sold and deployed) operates at a bit rate as high as 54 Mbps and uses the C-Band ISM, which operates in the frequency range of 5.725 to 5.875 GHz. Instead of DSSS, 802.11a uses OFDM, which allows data to b...
:( does that help at all, and is that at all what you're looking for? jeff jeff, that is brilliant. can i borrow your brain for a couple of years :) will hand it back after. promise!! i get everything you have just said, but... i still get stuck...
it may be due to channel interference. A WiFi connection with an adequate signal level, greater than -75dBi, does not disconnect. If this occurs, it may be due to problems with WiFi devices communicating with each other. It is advisable to ...
Such an approach has been used for several decades [130], [134] and is still used in state-of-the-art DSSs, like the one presented by Wątróbski et al. [177]. However, the subjectivity is also driven by the nature of the characteristics the systems work with, though here the ...
However, this does not provide a comprehensive assessment on how the tools are being used in practice since information on this may not necessarily be documented in the literature we were able to access for this review. 4. Discussion 4.1. Using decision support tools to integrate resource ...
Each device on a network has to be identified by a unique IP address in order to communicate through a router across links – link-level communication through switches is managed with MAC addresses. If a device does not have an IP address, other devices on the network cannot contact it. If...

(DIFS) period. The short interframe spacing (SIFS) is used as the wait time between the RTS, CTS, DATA and ACK frames. Since the SIFS is always shorter than DIFS, this ensure that another node does NOT incorrectly determine that the channel is idle during the handshake and that priority...
The borders of the sectors were major streets, the Vistula River, or compact built-up areas, which made them easily identifiable during the fieldwork. The sectors differed in terms of their area and habitat structure. Ten sectors were forest-dominated; the rest were covered by other habitats ...
