Follow Eli on the Vlog Channel: https://www.youtube.com/user/EliComputerGuyLive Info Level: Beginner Presenter: Eli the Computer Guy Date Created: August 2, 2010 Length of Class: 54 Minutes Tracks Telephone Systems Prerequisites None Purpose of Class This class introduces students to the basic components of telephone systems. Topics Covered Public Switched Telephone Network Central Offices Trunk Lines PBX and Voicemail Systems PBX Stations Voicemail Subcribers Class Notes Introduction Telephone systems are not complicated if you understand how they work. A Word on VoIP VoIP is not a telephone system PSTN PSTN -- Public Switched Telephone Network is like the Internet, but for telephone communication NADP -- North American Dialing Plan -- Is the system for routing telephone calls. Central Office -- All telephone lines connect to a local central office Trunk Lines Every Trunk Line has a telephone number A Trunk Line allows for 1 incoming or outgoing call. You can have far more telephones in a building then you have trunk lines. Incoming Trunk lines are setup in Hunt Groups. If the main phone number is busy the call is automatically forwarded to the next number in the Hunt Group Incoming Hunt Groups are setup by your local telephone company. Outgoing calls can be routed to use selected trunk lines. This in configured in your PBX. PBX and Voicemail The PBX routes telephone calls The Voicemail system provides all audio messaging. (Voicemail boxes, Message Boards, and Auto Attendant Messages) Stations All devices that connect to the PBX are "Stations". This includes telephones, call boxes, intercom systems, etc. There are 2 types of stations; Analogue and Digital. Analogue and Digital stations have to be connected to appropriate ports on the PBX. An analogue phone cannot connect to a digital port and vice versa. Almost all fax machines and phones you buy at retail stores are analogue. If your new fax machine does not work it may be because it's plugged into a digital line. Subscribers Subscribers are users of the Voicemail system. Subscribers do not have to have stations Voicemail ports are the number of connections to the Voicemail system at any one time. This includes not just people retrieving their voicemail, but also incoming calls that connect to Auto Attendant messages. Final Thoughts Be careful before you touch! Most older telephone and voicemail systems were administered using a phone keypad, NOT and computer interface. If you mess something up it can be very difficult to rebuild a deleted Auto Attendant or such. Resources North American Numbering Plan PSTN -- Wikipedia

Everything You Need to Know About 5G

Millimeter waves, massive MIMO, full duplex, beamforming, and small cells are just a few of the technologies that could enable ultrafast 5G networks. Read more: http://spectrum.ieee.org/video/telecom/wireless/everything-you-need-to-know-about-5g Today’s mobile users want faster data speeds and more reliable service. The next generation of wireless networks—5G—promises to deliver that, and much more. With 5G, users should be able to download a high-definition film in under a second (a task that could take 10 minutes on 4G LTE). And wireless engineers say these networks will boost the development of other new technologies, too, such as autonomous vehicles, virtual reality, and the Internet of Things. If all goes well, telecommunications companies hope to debut the first commercial 5G networks in the early 2020s. Right now, though, 5G is still in the planning stages, and companies and industry groups are working together to figure out exactly what it will be. But they all agree on one matter: As the number of mobile users and their demand for data rises, 5G must handle far more traffic at much higher speeds than the base stations that make up today’s cellular networks.

What is WDM (Wavelength Division Multiplexer)? - FO4SALE.COM
 
04:34
http://www.fiberoptics4sale.com WDM stands for Wavelength Division Multiplexing. WDM is the most important and most popular method to increase the capacity of a single strand of fiber. As we all have learned from elementary school science, a white light beam can be separated into individual colored light beams by a prism, as shown in this picture. Vice versa, individual colored light beams can also be combined into a single white light beam by the prism, that is if we use the prism in the reverse direction. WDM uses this same idea. Traditionally, only one colored light was used on a single strand of fiber to carry the information, such as 1550nm light. However, starting from the early 1990s, the Internet boom pushed service providers to find a method to increase the capacity on their network in the most economical way. That is when WDM devices were invented. As shown in the right side picture, in a WDM system, many different colored lights are combined by a WDM multiplexing device and put into a single strand of fiber, each color is called a channel. On the receiving side, each color is separated into its own channel by a WDM de-multiplexing device. It shows that a single fiber's capacity is increased by 40 times with a 40 channel WDM. The beauty of WDM is that you only need to upgrade the end equipment, no need to dig up trenches to bury more fibers, which is much more costly. So how are WDM devices made? This picture shows a 3 channel WDM device based on thin-film filters. Thin-film filters are a piece of flat surface glass with optical coatings on it. The optical coatings are designed to pass and reflect certain colored lights. This is a de-multiplexing WDM device, which means that it separates combined colored lights from a single fiber into separate individual fibers. But if used in the reverse direction, it can also combine different colored lights from individual fibers into a single fiber. As shown, three colored lights, which are 1510nm, 1530nm and 1570nm, come from a single strand of fiber 1. The GRIN lens collimates the light so it won't diverge into a large un-controlled beam. Filter 1 is designed to pass 1530nm and 1510nm, but reflect 1570nm. So when the light hits filter 1, 1570nm is reflected and re-focused into fiber 2 by the GRIN lens. Now the light has 1530nm and 1510nm in it, and it keeps going until it hits filter 2. Filter 2 is designed to pass 1510nm but reflect 1530nm, so 1510nm light passes and is focused into fiber 3 by the 2nd GRIN lens. On the other hand, 1530nm light is reflected by filter 2, passes filter 1 again, and is focused into fiber 4 by the 1st GRIN lens. Why isn't 1530nm focused into fiber 2? That is because the filters have a thickness, so there is a offset on the vertical direction. We just talked about a 3 channel WDM device. Thin-film filter based WDMs can be cascaded together to get higher channel counts, such as 4, 8, 16, 32 channels. The right side picture shows a 8 channel WDM device. The left picture shows how it's made by cascading several WDMs together. In additional to thin-film filter based WDMs, there are also fused fiber based WDMs, Arrayed Waveguide Grating based WDMs, Interleaver based WDMs, etc. They use different mechanisms to separate the colored lights. So there you have it. Please don't forget to visit http://www.fiberoptics4sale.com for more free fiber optic tutorials. I will see you in the next video!

2.2 - MULTIPLE ACCESS - FDMA/TDMA/CDMA/OFDMA
 
06:08
Multiple Access - FDMA/TDMA/CDMA/OFDMA in 4G LTE Multiplexing is the process of combining multiple signals and transmitting them over a common channel and it is implemented on telecommunication using Multiple Access as a Application. Here, Multiple Access is explained with the example of Wi-Fi Hotspot sharing its internet connection among multiple users by providing them a frequency block over which they can transmit and receive data. The greater the size of this block, greater is the throughput. There are several way by which we can use Multiple Access Technique such as TDMA, FDMA, CDMA, W-CDMA, SDMA, OFDMA, SCMA. We have also mentioned, How TDMA and FDMA, CDMA, W-CDMA works and implemented in Earlier Generation system which is AMPS, GSM, GPRS, EDGE, UMTS, HSPA+. To overcome issues faced in earlier generation such as, - Low Throughput - Low Spectral efficiency - Resource wastage and many more, We have introduce next Generation Multiple Access technique which is already deployed in WIFI and in WIMAX, but due to lack of backward compatibility and support for Mobile communication in WiMAX, Operator started to working OFDM to include in LTE.

Awarded as “Best Apps of 2016” and “Best Self Improvement App of 2016” by Google Play. Like us on Facebook: www.facebook.com/UDictionary/ this video is in tamil language. In radio and electronics, an antenna (plural antennae or antennas), or aerial, is an electrical device which converts electric power into radio waves, and vice versa. It is usually used with a radio transmitter or radio receiver. In transmission, a radio transmitter supplies an electric current oscillating at radio frequency (i.e. a high frequency alternating current (AC)) to the antenna's terminals, and the antenna radiates the energy from the current as electromagnetic waves (radio waves). In reception, an antenna intercepts some of the power of an electromagnetic wave in order to produce a tiny voltage at its terminals, that is applied to a receiver to be amplified. Antennas are essential components of all equipment that uses radio. They are used in systems such as radio broadcasting, broadcast television, two-way radio, communications receivers, radar, cell phones, and satellite communications, as well as other devices such as garage door openers, wireless microphones, Bluetooth-enabled devices, wireless computer networks, baby monitors, and RFID tags on merchandise. Typically an antenna consists of an arrangement of metallic conductors (elements), electrically connected (often through a transmission line) to the receiver or transmitter. An oscillating current of electrons forced through the antenna by a transmitter will create an oscillating magnetic field around the antenna elements, while the charge of the electrons also creates an oscillating electric field along the elements. These time-varying fields radiate away from the antenna into space as a moving transverse electromagnetic field wave. Conversely, during reception, the oscillating electric and magnetic fields of an incoming radio wave exert force on the electrons in the antenna elements, causing them to move back and forth, creating oscillating currents in the antenna. Antennas can be designed to transmit and receive radio waves in all horizontal directions equally (omnidirectional antennas), or preferentially in a particular direction (directional or high gain antennas). In the latter case, an antenna may also include additional elements or surfaces with no electrical connection to the transmitter or receiver, such as parasitic elements, parabolic reflectors or horns, which serve to direct the radio waves into a beam or other desired radiation pattern. The first antennas were built in 1888 by German physicist Heinrich Hertz in his pioneering experiments to prove the existence of electromagnetic waves predicted by the theory of James Clerk Maxwell. Hertz placed dipole antennas at the focal point of parabolic reflectors for both transmitting and receiving. He published his work in Annalen der Physik und Chemie (vol. 36, 1889). Yagi antenna A commonly used directional antenna is the Yagi-Uda Array, usually just called a Yagi. It was invented by Shintaro Uda and his colleague, Hidetsugu Yagi, in 1926. A Yagi antenna uses several elements to form a directional array. A single driven element, typically a dipole, propagates RF energy; elements placed immediately in front of and behind the driven element re-radiate RF energy in phase and out of phase, enhancing and retarding the signal, respectively. The elements are called parasitic elements; the element behind the driven element is called the reflector, while the elements in front of the driven element are called directors. Yagi antennas have beamwidths in the range of 30 to 80 degrees and can provide well in excess of 10 dBi passive gain.
