Innovation Network Technology

WDM Fiber Network stands for Wavelength Division Multiplexing Fiber Network. It is a ground-breaking concept that was published in 1972 and was finally materialized by the late 70s. To understand this concept clearly one should first know how an optic fiber functions. An optic fiber works by converting data in the form of electrical signals into light signals at the transmitting end and then converting them back into electrical signals at the receiving end. The main advantage of this technology is that the speed of transfer is enormous considering that data is transmitted in the form of light.

In a WDM Fiber Network multiple channels of data are transmitted through a single optic fiber using light signals of non-overlapping frequencies. Each channel is independent and carries data in a specific frequency. Since, multiple channels are combined together; this technology exploits the maximum bandwidth of the optic fiber.

WDM Fiber Network uses a multiplexer at the transmitting end which combines various signals of non-overlapping frequencies into a format which can be transmitted using a single optic fiber and a device called demultiplexer at the receiving end in order to separate the different independent channels of data. Light signals are split into independent strands holding data and are then transmitted at varying speeds of 2.5 Gbits/sec, 10 Gbits/sec, etc. Initially when developed scientists were able to transmit only 2 different channels together. Today with rapid advancement occurring in this field one can send across as much as 160 channels of data. Furthermore, when an optic cable is used which is nothing but a bunch of optic fibers held together, the amount of data that can be transmitted is unbelievable. If for example a cable consists of 8 optic fibers and the speed of transmission is 10Gbits/sec, the total amount of data transmitted would be 80Gbits/sec. In other words, the fiber advantage is literally multiplied in a cable. Continue Reading

Dish Network is one of those rare companies that embodies the spirit of true American innovation. It’s attracted the loyal allegiance of over 11 million subscribers, and won accolades and respect from the rest of the television industry. It’s done this through a two pronged approach of providing entertainment packages designed to appeal to a variety of people and supplying it’s subscribers with the best television technology currently available.

The technology that Dish Network utilizes has been truly impressive from the beginning. All Dish Network programming is delivered in one hundred percent digital format. This means that it’s free of all but the worst interference for a crystal clear picture and great sound quality. Digital television also makes it easy for Dish Network to provide extra features along with the programming. For example, the Dish Interactive Electronic Program Guide displays all of the shows available to you in the form of a table just like you’d find in your local newspaper. Each cell in the table is occupied by a show and has information to help you decide whether or not you’d like to watch it. You can scroll up or down through the channels, or left or right to see different time slots. Some receiver models let you see what’s scheduled to be on up to nine days in advance. Dish Interactive also brings you information about the weather along with online games that no analog signal can provide.

More advanced technology is also available. Dish Network can provide receivers that can sent two separate television signals to two TV’s. This way one person can sit in the living room and watch one program, while someone else can sit in a bedroom and watch a completely different program without the added complication of having more than one receivDish Networker. This is accomplished by the remote that goes with the second TV operating on a UHF frequency which can not only penetrate walls, but is also very different from the IR frequency used by the one in the living room, so that the receiver doesn’t confuse the two.

Digital Video Recording is also built into some Dish Network Receivers. Digital Video Recording lets you record the programs that you want to watch regardless of whether or not your home, so you can watch them when you want to. A Digital Video Recorder is far superior to a VCR because it doesn’t use tapes and you can tell it what you want to record quickly and easily using the Dish Network’s Electronic Program Guide.

There is no doubt that this is the time of several technological innovations. Several technologies have come in limelight, which are being proved very useful for the people. Wi-Fi is one such technology which has come up with a great innovation. This technology has brought a new aspect in the arena of networking. It broadcasts data via radio waves rather than cables. With the help of this feature, you can access unlimited Internet in the Wi-Fi supported areas. Normally, college & offices campuses are supported by Wi-Fi.

It is well known that today mobile phones are multi-functional devices. Wi-Fi technology has also become the part of these gadgets. There are a number of Wi-Fi mobile phones being launched by the handset brands which on one hand provide Wi-Fi technology, on the other hand offers a plenty of other sophisticated features. Some of the Wi-Fi handsets can be taken as instances in this regard.

The Nokia N97 is one of the most demanded handsets in the present scenario. The gadget offers Wi-Fi 802.11 b/g to the users. Some other features of this brilliant handset include wonderful camera features, excellent storage space, messaging, GPRS and many others. Starting from the mobile phones, the gadget comes equipped with 5 MP camera. LED flash and video light features of the camera allows you to capture clear images and videos respectively in the dim light conditions. Other camera features include carl zeiss optics, autofocus and geo-tagging. About the storage space, the handset has a mammoth internal memory of 32 GB plus a microSD card slot to add more memory up to 16 GB. Stay in touch with loved ones with its SMS, MMS, Email, Push Email and IM features. GPRS allows you to access Internet anywhere with the help of network service providers. Continue Reading
