The scarcity of water around the world is forcing the water authorities to use water resources which are scattered in remote areas with low accessibility and impossible permanent wire connections. On the other hand, the water resources are generally in long distances between each other and all of them are very far from the water consumption area. This constrains the administrative organizations to spend human and fund resources for controlling, monitoring and maintaining the installations with poor results, since no constant supervision can be achieved. The technological combination of wireless broadband networks (wifi), modern systems of signal control and data acquisition, computers/software and telematics can provide an excellent solution for this problem. In this video the process of planning and installation of a system, for the telematic control and management of eleven wells and storage installations and distribution process for the Municipality of Thira (Fira, Santorini, Greece) is presented. The installation is checking the pumping stations, the levels of water tanks as well as qualitative data of the water supplies, from distance through a wireless network. The system interacts automatically or manually with the installations and to preset points, giving complete records of the data and alarms to any malfunction or oncoming breakdown. The proposed solution is expandable regarding the installations in control and the signals which are collected and checked. The …

EPON Optical Network PHS times of Copper (map)-EPON, light of Copper, PHS – Communications Industry

Article by hi joiney

Introduction: This paper discusses the current use of Copper-optical EPON under the premise of the original use of PHSOE technology transfer with the copper wire PHS Business network transformation of light to avoid to keep copper PHS network transmission caused by “light into the copper, no withdrawal” embarrassing situations. Today’s trend is also necessary to reform on the PHS transmission network it? Look at the Internet under a very typical post: “Using the olt + onu on , the original PHS base stations, how do? If you use the built-in voice IAD of ONU to solve the problem, then It had access through the copper (ISDN) of the PHS base stations, how do? If onu only solve part of broadband, voice also use the original copper, then that is the trend of light into a copper refundable. Ha ha! hard, small Linktone network is not 12 years back can be completed. personally think, in a PHS light into the area can only reclaim the copper. ” 3G Telecommunications restructuring Mobile One-way fees, all the important technical and policy factors into the mountains of PHS business seems to the point where poor water complex, and recent rumors of a significant reduction in the PHS users seem to confirm the judge, however, PHS business and user In the return to a reasonable level but should be kept after a certain size than the present state of small but still substantial, imagine nearly 80 million PHS users are able to cutover once it? PHS base stations to 1.6 million nationwide, said scrapping the retirement? A large number of special user group is we want to turn they answer it? Pregnancy as additional households per year, and now statistics is the first half of pregnancy, almost 80% of women will replace the original PHS mobile phone, when the PHS mobile phone all into what Communicate To meet the requirements of their Low-E? Therefore, the PHS business in the next 3-5 years should not be suddenly stopped, PHS will continue to run, but the face of EPON FTTH technology for the major reconstruction, mainly composed of PHS base stations by the twisted pair to the Board end of the transmission network seems to be a stumbling block for FTTH, carriers will want to light when the steam head back into the copper wire are all digging will come to know an copper wire in two dug, the cost is too high, so FTTH can be passing the time in hand will also be light PHS transmission network of Copper is of course necessary. What is PHSOE? Why is PHSOE? PHSOE (PHS overEthernet), developed for the Chengdu Si Dawei way through the circuit is really against the second floor with a reliable Ethernet data port of a U PHS technology, the use of the technology can EPON, Fiber Transceiver , MSTP / MSAP optical network such as Ethernet and reliable data transmission PHS U port. If so, why did we choose PHSOE technology has become the light of the PHS network of Copper’s main technical means? First: the cost of the PHS network transformation and even as far as possible without spending a small cost; Second: to use the existing fiber optical network without occupying resources; again: to provide for its reconstruction is a common interface to a wide range of coverage. We now analyze the traditional PHS network transmission network and platform in the EPON network after transformation with PHSOE the network diagram: Figure 1: Traditional PHS twisted pair transmission Figure 2: In the EPON technology transfer platform through PHSOE PHS network transmission plans Through the network diagram to analyze whether we meet the above conditions, 1, while the implementation of the FTTH EPON network without the need to use to build the network, and dig out the high twisted pair resources can be recycled at the same time when the EPON network installation need not repeat the construction or installation, thus greatly reducing the cost; 2, and all the light into the retirement program is not the same as copper, the technology has been built only Ethernet optical network platform without extra a fiber-optic; 3 , PHSOE need network interface is Ethernet interface, and the interface for most of the light Network equipment Provide extensive coverage and easy construction. Based on the above factors PHS network transformation chosen PHSOE technology. How? Circuit against the clock really to ensure good transmission delay jitter and can only transmit timely PHS voice service, taking into account the Ethernet technology is based on store and forward mechanism, two mechanisms for achieving this will determine its difficult to protect the transmission delay and clock extraction, and therefore extremely difficult to achieve the time. Our concrete implementation is achieved using SW1304F chip, the chip to achieve a good U-port Ethernet-based circuit emulation and integration into the U population control program, in the realization of PHSOE related equipment only in their peripheral accessories U Ethernet port and a simple circuit can.

Fibre Optic Cable Strengthens The Communication Network

Article by Andre Kakkar

Today, Fibre Optic cable has become the prominent medium for high-speed transmission of large amount of data as well as for customized computer networking system. In spite of being expensive, most of the companies are installing optical cables to have un-interrupted and speedy transfer of information via wide range of computer devices.These days telecommunication applications of fiber-optic cable are widespread, ranging from global networks to desktop computers. Generally fibre cables are the bundle of thin glass threads (also called optical fibres) that are capable of transmitting any amount of data without any loss. These flexible fibres can be grouped together, and the resultant cabling network functions at superior bandwidths in comparison to other kinds of transmitting information media. Since these glass fibres go through low level of reduction and hindrance, they are extremely effective for various telephonic applications.

Nowadays internet is a most prominent mode of communication, thus use of fibre technology ensures secure data transmission and networking in seconds with minimal loss of records. Many different types of telecom providers, like cable businesses and telephone service frequently uses these advance cable to have fast and better mode of communication. In-spite of the cost factor, most of the traditional telephone lines is getting replaced by cable optic technology for smooth, safe and easy transfer of information.

Today, most conventional communications media including telephone, music, film, and television are reshaped or redefined by the internet, giving birth to VoIP service (Voice over Internet Protocol) and IPTV. With effective web network through modern fiber optic cabling structure, one can easily be able to watch live high-definition videos and movies, easily do video conference in real time, download large media files within moments and do a lot more things that are hard to do few decades before.

Wireless internet and fiber optics offer out of the ordinary services that not only needed by large business corporate but also can be made use of at home. But due to lack of knowledge many people tends to relate the CAT cable as optical cables. Generally these cables are comprised of four copper wires that are twisted together, very similar to phone line. As compare to fibre cable, later uses electrical signals to transmit data from one source to other. These copper wires are cheap to install but they are insecure and have risk of data loss while transmitting through different mediums. Fiber optical provide much better bandwidth transmission capabilities and security as compare to these Ethernet network cables.

Though expensive, optical technology is now being widely used as lan cable in most of the corporate offices and telecommunication industries. These are extremely useful for local-area networks or LANs which is confined to a relatively small area such as a single building or a group of buildings. With such large number of advantages, the time is not far when fibre optic cable will surely outshine all types of networking cable system.
