... The most deployed standards around the world are IEEE 802.11a, 802.11b, and 802.11g since they were the first deployed ones. They use different physical layer technologies, and so they are different in terms of frequency, transmission rate, modulation and behavior against interferences [4]. However, they can work together and there are available many devices dual-mode (IEEE 802.11a/g) and even tri-mode (IEEE 802.11a/b/g) because they share the same medium access protocol CSMA/CA (Carrier Sense Multiple Access / Collision Avoidance) [5]. ...
... It leads to think that in spite to cover a larger distance, data rates and modulations used at the longest link (A to B link) are less susceptible to variations of weather conditions. In this point, it is essential to comment that transmissions are not synchronized as ICMP packets are sent one per second to each wireless client, however as the slot timing is in the order of microseconds [4], these transmissions are considered at the same time as they are comparable in terms of the weather's impact for this so short difference of time. ...

The weather’s impact on the performance of a radio link at the 2.4 GHz ISM (Industry, Scientific and Medical) band had not been yet studied in great detail up to now as it is generally believed that the ultra-high frequency band is not significantly affected by weather conditions. However, our study shows significant correlations between meteorological variables and control frame errors at MAC (Medium Access Control) layer of the IEEE 802.11b/g standard. This study is performed over an outdoor radio link setting which has been monitored for several months. Moreover, we check if link distance and so modulation scheme and data rate are also decisive features of such impact. Our real scenario is composed of a point-to-multipoint link, one longer distance’s than the other one. Finally, we conclude that the weather impacts on the number of control frame errors, and so it should be taken into account to design and deploy outdoor radio links IEEE 802.11b/g. Moreover, we have showed that such impact depends on data rate and modulation scheme.
... The first standard promoted by the Alliance was 802.11b and used the frequency of 2.4 GHz, which allowed data rate of 11 Mbps in the range of 400 meters in the open space and 50 meters inside the buildings, if there were no interferences. In the area with interferences, the standard allows dynamic decrease of transfer rate down to 5.5 Mbps or less [5]. Introduced in the same time, standard 802.11a ...

The Institute for Sustainable Technologies – NRI in Radom, together with Silesian University in Gliwice, have developed a group of mobile robots [1] intended for support of rescue actions. The group consists of two big robots: Explorer for exploring the environment and Transporter for transporting the number of small robots – Pathfinder (Fig. 1). The Explorer robot is capable of monitoring the environment in terms of temperature measurement, measuring the concentration of gases in the atmosphere and collecting the samples of soil. The Transporter is capable of transporting small robots and picking small objects as it is equipped with a container and a robotic arm and its purpose is to move small robots as close to the hazardous place as possible. Small robots called Pathfinder are intended to penetrate the area such as the room on fire and find potential victims or just allow the reconnaissance. All robots are equipped with one or more cameras and audio system for duplex communication. All the functions require the reliable and fast method of communication with enough bandwidth for the transmission of full duplex audio stream next to the simplex video stream and duplex control data stream.

The present work analyzes and compares two popular standards for data transmission over power line networks: PRIME and G3. A complete and detailed description of both standards is presented together with simulation results of their performance in a power line environment. In order to create an accurate analogy of the transmission channel, background and asynchronous impulsive noises are included using previous results from literature. Simulation results show how PRIME and G3 behave in several noisy environments. Finally, with respect to PRIME, a proposal is made to increase its performance in a hardly impulsive noise channel.

The increasing amount of bandwidth requirements and quality of service needs for the next-generation access networks has boosted extensive research in the fiber-optics communication field. In this light, passive optical networks (PONs) combined with optical code division multiple access (OCDMA), provide a potentially cost-effective solution to meet such bandwidth demands. This work proposes an optical transparent architecture which enables all-optical communication between the network nodes. The encoded data streams are multiplexed at a merging point which results in multiple user interference (MUI), thus significantly reducing the network throughput. The networking nodes are able to monitor and record user activity in the PON, and further register the (past) state of activity at the merging point. In this work, we study the coherence of state between the networking nodes and the merging point, for different packet size distributions, in order to predict an optimal transmission instant of each node's data packets. We note that the states are coherent depending on the packet size distribution.
