Digital Signage - High-Definition Wireless Media Player or wired?

Digital Signage is steaming ahead with new technologies all the time, now are different types of media players used for the storage and playback of content for advertising campaigns.

digital signage integrators now have the choice of a stand-alone WiFi or wired media players and the reason to use drops in price, time and the application will be used.

Content alone players.
These media players are usually associated withposters with digital screen and built in an all in one digital signage solution. These are powered by electricity and must be updated manually through a USB connection.

WiFi HD Media Player.
They have the ability to create up to 1000 GB of data and full resolution of 1080p high-definition offerings. These are at the sharp end as they come, complete with HDMI connector to connect directly to flat panel displays and will also support Flash andMPEG 1,2,4 also supports MP3, WMA, WAV and AC3 audio files. What makes it innovative is that there is a WiFi connection built into the reader, to use a laptop to access and load data from a remote location, operates on 802.11g wireless network and is backward compatible with other wireless networks .

Wired high definition player.
As the name suggests you have this media player to a computer network so that content can be loaded,This method is thought to be the most traditional, but can be very expensive due to the use of fiber optic cable when the installation is a bay football stadium.

They are also used to install digital menu boards and are usually connected to the back of the screen and run cables back to a PC near the bar, where the updates can be synchronized.

Deep Sea disconnections - Broadband

While we all believe that the satellites floating around the earth are responsible for the TV and the fact that we watch the Super Bowl in America across the Atlantic in the UK, the same can not be said for the Internet. The Internet is maintained by a vast network of copper and fiber - fiber optic cables and all connect to the Internet, there is some form of cabling infrastructure.

Many of these submarine cables, inrunning under the water, are well fortified with up to nine layers of components to ensure these vital cables are not disturbed. The problem is that the cables under the Mediterranean Sea have been divorced, was originally a cable linking Egypt and Italy was broken, but two others have been cut causing global problems with a broadband internet service disrupted in some Middle Eastern countries like Iran, India and Egypt.

The biggest concern was thedisruption of telecommunications in these countries, especially India, that so many people will know is home to thousands of call center outsourcing, BT was quick to redirect their network to cope with the disorder and reports say that although t ISN quality phone 'as clear as normal, it is still viable.

The problem is that small businesses with less detailed plans are suffering; Vikas Jain, assistant vice president at AEZ Group, a propertydeveloper said: "We have a lot of offices connected to the same way because the internet is down means we are cut off from headquarters,"

This problem is not the first of its kind, broadband and other telecommunications services in Taiwan have been stopped months in 2006 after an earthquake has succeeded in 7 of 8 wires for the Asian continent to destroy. Repairs are expected up to 10 days stretched to months to return to your speed. With the recent accident repair shipsare sent to the port before the situation gets worse repair.

The reason for this distortion? Apparently, the best guess is that a tanker had dragged its anchor along the seabed. The repair is probably a week since the release of repairs arrive, while the Minister of Communications and Information Technology of Egypt said that broadband services would be back in Egypt up to 80% within 48 hours after the initial deployment to be. We hope that the World Wide Web will return to powersoon!

What Is FTTP, FTTH, FTTB and FTTD? Fiber Optic Tutorial Series Four

FTTP stands for Fiber To The premises is a kind of optical fiber communication episode in which a fiber connection directly exported to customers' premises. P (local), commercial, institutional and other applications where connections are distributed on a campus fiber network, a forest, or building high-density with a central Network Operations Center. Some others, such as FTTx FTTN (fiber to the node), FTTC (fiber to the curb)still depend on copper wires for "last mile" (permanent link) for customers, which contrasts with FTTP. FTTP can be further divided in FTTH (Fiber to the home), FTTB (fiber to the building), etc.

FTTP network construction

FTTP network can be divided into two main parts: optical and electrical cross-sectional area.

1. Optical

optical part of the FTTP network is responsible for implementing optical signal to electricalpart (the electrical room is located in telecommunications customer). There are two configurations for the FTTP optical fiber. These are the direct connection of fiber and fiber shared.

direct fiber connection is the simplest form. A fiber is used for direct connection to the central office to a customer. This type of connection provides the customer with the highest bandwidth, but also the most expensive configuration. Shared fiber: a single fiber so that the centeroffice is shared by many customers. Only at the last moment, the fiber is split into many individual fibers to each customer.

There are two main competing technologies for the configuration of the fiber in common: active optical network (AON) and passive optical network (PON).

Active Optical Network (AON) is much more similar to traditional Ethernet networks. Must be electrically powered equipment to buffer and distribute the signal, such as switches and routers. Each starting signalThe head office will be led only to the client from the router or switch. On the other hand, the signals of customers buffered by the router at the junction to avoid conflicts.

Passive Optical Network (PON) is electrically powered to be used to buffer and route the signals. Instead of signaling the central divided and distributed to all customers, even those not listed. When the light signal arrives at the electrical andwhere it is converted into electrical signals by the ONT (see below), the ONT decision to retain or eliminate the signal depending on the destination.

2. Electrical equipment

electrical part of the FTTP network receives the optical signal and converts it into an electrical signal is then distributed traditional desktop computer through a network of copper wires LAN. This device converts the call of optical network termination (ONT). The telephone building systems, and LANcable TV system are then connected to the ONT.

Other FTTx

FTTB: Fiber To The Building. This is a reference to fiber optic data network linking all the way from an Internet service provider for the client's physical condition of a building.

FTTD: Fiber To The Desk .. FTTD shows applications that are distributed fiber connections from the central office to individual workstations or computers in a structure,house or building.

FTTH: Fiber to the Home. FTTH fiber network connections will be held at the Central Office for a residence permit, or very small multi-dwelling units.

FTTN: Fiber to the node. FTTN is also known as fiber to the neighborhood or fiber to the cabinet (FTTCab). It is based on an architecture for telecommunications fiber optic cables run to a closet where a district.

FTTC: Fiber To The Curb. This is known as Fibre to therebellion (FTTK). It is a telecommunications system based on fiber optic cables run to a platform that serves different customers. Every customer has a connection to this platform via coaxial cable or twisted pair.

As fiber optics work?

Glass fiber is used with increasing regularity because of the numerous advantages it offers compared to more traditional data technologies such as copper. But what is fiber optic cables to them effectively?

How are fiber optic cables are made?

Refers to the application of fiber optics to transfer data through light signals to transmit. Most optical fibers are made of glass or, less commonly, plastic. Glass is often usedbecause there is less signal loss over long distances with plastic.

Each optical cable is basically composed of two "layers". The center is called "core" and this is where the signals are sent through the light. Surrounding the core is the second layer, named as the coating. The coating is what keeps the signal within the nucleus, using a principle called total internal reflection. " The coating is reflective, leading indicators of light to travel through the core, while theprevent signal leakage or be absorbed by external components.

Single mode and multimode fiber

Optical components can be grouped into two main categories. The first is called single-mode fibers support a single propagation path, whereby a signal at a time. Single-mode be used for most communication links longer than 200 meters. Alternatively, there are multimode fibers. These usually have a core of large diameter and are used for short-range communication linksor for applications where high power must be transferred.

How is the information passed to the light?

The light signal transmitted through these wires is not actually a continuous beam. Rather, it is composed of short sequences of light signals. This process is derived from the Morse code, the communication system with a series of long and short of the individual values. That's because the computer code consists of only 1 and 0.

Fiber Optics offers many advantages over traditional wires, like copper. optical components, higher transmission speeds, higher speeds and greater reliability. They are safer and actually cost less in the long run compared to the metal. Unlike metal wires, optical wires are immune to electromagnetic interference, have a much lower risk of fire or shorts, and prevent cross talk between the wires next.

For these reasons, the fiber has become the best choice for many industries, including telecommunications systems,> TV broadcasts via cable and data networks.
