Get rid of wires through Wireless Technology

There era many wired devices that still exist, and people sue them, but they sometimes become very irritating as wires become cluttered, and this even lead to damaging or breaking of the cables. So wireless technology was invented. The technology was started in the 19th century, and now it has been developed to a much higher level. The technology is still under development. People are using the technology to communicate, connect to the internet, and many others. Here we will discuss various types of wireless technologies.

Satellite Communication

This is wireless communication, which is spread all over the world. People can connect even if they are separated by a long distance. In this technology, a signal is sent to the satellite, which provides energy to the message and sends it back to the antenna receiver. The two main components of this technology are the space segment and the ground segment. The equipment used in the ground segment can be mobile transmission or a receiver, and the space segment includes the satellite.

Infrared Communication

This system uses infrared radiation to communicate with various devices. The wavelength of this radiation is more significant than that of red light. The technology is used in TV remote control, security control, and other short-range communication. The main components required for this type of transmission include a photo LED transmitter and photodiode receptor. The task of the LED transmitter is to transmit the light, and the receptor stores it.

Broadcast Radio

This is the first wireless technology and is still in use nowadays. There are multichannel radios, which users can use to speak over shirt distances. The maritime radios were used by the sailors to communicate. Data can be easily shared with Ham radio. This technology is also used for digital communication over a radio frequency spectrum.

The sound is broadcasted by an audio broadcasting service in the form of radio waves through the air. There is a transmitter, which is used to transmit data from the radio to the radio receiving antenna. Simulcast, syndication, or both formats are used to broadcast the data.

Microwave Communication

This type of communication uses radio waves whose wavelengths are measured in centimeters. There are two methods in which data can be transmitted. The first one is a satellite, and the second is the terrestrial method.

In the satellite method, the data is transmitted to the satellite whose distance is 22300 miles. The data are sent and received to and from the stations — the frequency of sending and receiving data ranges between 11 GHz to 14 GHz. The speed of transmission of information ranges between 1 Mbps and 10 Mbps.

In the terrestrial method, there are two towers, and there should be no obstacle between them. The frequency of data transmission is 4 GHz to 6 GHz, and the data transmission speed is 1 Mbps to 10 Mbps. The signals are disrupted by rains, and this is the main disadvantage of this type of communication.


Wi-Fi is a wireless technology, which comes with meager power. This technology can be used in laptops, mobiles, tablets, and other such devices. Users need to install a router for Wi-Fi communication. This technology is used in networking applications, which are protected by passwords.

Bluetooth Technology

Users can use this technology to connect various devices wirelessly with each other for communication. Information can be easily transmitted from one device to the other with the help of this technology.

Wrapping Up

These are wireless technology, which people can use for wireless communications. People will soon get rid of the cluttered wires because of this technology. The technology is still under development and has a good future.

Edit your pictures with Digital Cameras

Cameras have been used for many years. First reel cameras were used, and people were able to click only black and white images. Then cameras with colored lens came and in this case also, and reels were used. Then came the turn of digital cameras, and people can save the mages on their computers. Cameras also available in mobiles so now there is a need to use reels. People can save pictures on various devices like laptops or external hard drive. Here we will discuss different types of digital cameras.

DSLR Cameras

Digital Single Lens Reflex Cameras or DSLR Cameras are very popular and available in the market at a different price range. People can find many professionals with these cameras. The camera consists of a digital imaging sensor and a single-lens reflex camera. These cameras come with detachable lenses so users can change the glass based on the type of photography they have to do. The camera comes with the half-frame and full-frame options.

Mirrorless Cameras

DSLR cameras have an optical viewfinder, and if it is removed, t5he camera becomes the mirrorless camera. Removing the viewer will also reduce the weight of the camera a little. There are two types of mirrorless cameras, which include crop frame camera and a full-frame camera. These cameras also have the feature of the detachable lens, but the options of glass is very less as these cameras are new in the market.

Point and Shoot Cameras

These cameras are compact and are valuable for those people who often go for a picnic which their friends and families. The main aim of such people is to click the pictures and store it on various storage devices. The camera has a fixed lens and variable focal length. The pictures clicked by the camera are best for documentation.

Smartphone Cameras

Smartphones are coming with great cameras. They have rear, as well as front cameras and users, use to click pictures anywhere they like. The front camera is used for taking a selfie. The software included for the cameras help the users to get blur and other types of effects. People who used DSLR cameras are happy with smartphone cameras. The smartphone cameras have declined the usage f point and shoot cameras. Users can click pictures in raw format and can edit it later.

Bridge Cameras

These cameras have the position between DSLR and point and shoot cameras. They have a fixed lens and has the feature of covering the telephoto lens. People who like to visit wildlife sanctuaries or enjoy a picnic but cannot afford a DSLR camera can buy the bridge cameras. These cameras support war format, and users can edit the pictures with the help of editing software applications installed on smartphones or laptops.

Medium Format Cameras

Previously 120mm films were used in these cameras, but now the cameras have a digital lens.  The camera has a big sensor and is available at a higher price. These cameras are suitable for those people who want to have high-quality pictures and noise performance. S8ch cameras are ideal for those people who are in the fashion designing field.

Film Cameras

The film was installed in these cameras, but now digital camera lens has taken its place. Still, films are used in these cameras because of the ISOP part of the images. Users need to change the movie regularly for ISO images.

Wrapping Up

There are various types of digital cameras available, and people can purchase them from the market or websites. The camera with a low price can be useful for going to a picnic or visiting a wildlife sanctuary. Professional cameras are of high quality and are used to i different professions.

Update: This is actually a computer monitor and not a 3D TV. The new series 9 monitors will come in 23″ and 27″ and will include a built-in 3D emitter.

Samsung is showing their updated ‘9-series’ 3D TVs (this is Samsung’s high end TV series) – with a beautiful ‘curved design’:

We don’t have any technical details yet, we just know that it’s a LED-backlit LCD. The current C9000, however, is ultra-slim (.3 inch thick) and supports Full-HD at 240Hz. The TV has built-in Wi-Fi (with Internet-Apps support) and a touch-screen remote that can show live TV via Wi-Fi. So we can guess that the new 9-series will have all that, and more. As soon as we have more information we are going to post a super detailed review. In the meantime you can check our friends at HopsReview for more information and marketing reviews.

Samsung will also unveil new Series-7 3D TVs at CES. We’ll keep you updated!

Buy the Sony 3D glasses now for $149.

Samsung releases new 3D glasses

Samsung has released 3 new 3D glasses today. All of them are battery operated (active-shutter) and require a Samsung 3D-ready TV with an emitter (such as the LED-LCD C7000 or PNC8000 plasma) and a 3D Blu-ray player (such as Samsung’s BD-C6900 that’s shipping for $399.).

  • SSG-2100AB: the basic model, costs $149
  • SSG-2200AR: – these are more expensive at $199
  • SSG-2200KR: these ones are for kids, come in pink and blue and cost $179

Samsung SSG-2100AB

All of those glasses are now available for pre-order over at, we do not know when they’ll ship yet. Interestingly, Samsung’s 3D-starter-kit includes 2 pairs of the basic model 2100AB, and costs $350 – so it’s cheaper to just buy two pairs at $299 (although the starter-kit includes a 3D Blu-ray movie – monsters vs aliens).

New 3D poster technology coming soon

The Fraunhofer institute, University of Kiel and RealEyes is showing a new technology that enables 3D posters for large (up to 5 meters) outdoors advertisements. And these do not require any glasses.

The researchers say that the display are similar to the lenticular images we’ve seen on postcards. But instead of the grooved sheet with the image attached, the new posters use a lens array – 250,000 lenses, each 2 millimeters in diameter. The 3D image can be viewed from the other side of the street, and the image appearance changes with each step and adjusts to the visual angle.

They have already built a DIN-A0 (1 sq meter) poster prototype, and they say that commercialization of larger posters (3 to 5 sq meters) is possible during 2011.


Today it  has been achieved and  it is being  commercialized  in Spain, such images with lenses of 1.25 mm or 20-inch lenses.Actually, this technology is not new, if it is true that recent times are getting an excellent quality,  almost, these days, it has gotten to produce  it  industrially  with a really very low cost.The optimal size at the moment is a traditional MUPI (1.2m. X 1.8m high).  It’s true you might get a panel of five meters cracked, but the problem lies in the placement of such portions in the same plane,   they must be perfectly flat  without any kind of inclination,  so  this would give us a picture also cracked.

HDI’s 100″ 3D Laser TV will cost $10,000-$15,000, first units available in May

HDI says that they will begin production of their 100″ 3D Laser TVs (1920×1080) in May. Mass-production will take a bit of time – hopefully by Christmas 2010. They also say that the TVs will cost between $10,000 to $15,000.

The TVs are 10″ thick, and weighs about 75% less than normal 100″ LCDs or Plasmas. They also draw 80% less power than a 100″ plasma. According to HDI, they do not contain any harmful chemicals, either.
