White space standards pubbed, bring on the devices!

Posted by on Wednesday, 27 July, 2011

Another hurdle was removed today for “Wi-Fi on steroids,” as the IEEE published a wireless standard that could bring high-speed broadband to rural areas. The 802.22TM-2011 standard will be used on frequencies that were used by analog television channels, but were freed up when the U.S. transitioned to digital television broadcasting over the air. Known as “white spaces” technology, the wireless standard supports transmissions speeds topping out at 22 Mbps per channel, with a range of up to 100 kilometers.

With the new standard now approved, hardware manufacturers have a blueprint to begin designing and building products that can use the upcoming wireless networks. Unlike the frequencies used by cellular network operators, the white-spaces use unlicensed spectrum (just like today’s Wi-Fi networks), so a wide range of compatible devices are expected from many companies. This would make it far easier and cheaper for those in remote areas to gain faster Internet access, for example.

Schools and enterprises could use the technology to deploy campus-wide wireless networks more easily due to the extended range white-space networks could bring. Google and other companies interested in smart-grids can benefit from intelligent, connected meters that shoot data directly to power distributors. And carriers could even supplement their current Wi-Fi offloads, which are very limited in range, with white-space networks. For more details on the potential uses of white-spaces, see our recent “everything you need to know” article.

On a more personal level, individual devices could gain a much greater range and connect directly to homes. I currently use a mobile broadband connection to manage the lights and temperature of my home, for example. But I’ve held off on adding some webcams for security and monitoring for package deliveries, simply because transmitting such video over a 3G or 4G connection will have me hit my data caps too quickly. With white-space devices and support, however, I could be miles from home and still keep an eye on things without worrying about monthly data caps.

We’ll be talking more about such connected devices and the networks they use at our two-day Mobilize event in September; with the new wireless standard now ratified, white-space networks are sure to factor into our conversations.

Car Dvd Players Reviews: Quick Guide To DVB-T Which Regions It Works In And How It Can Boost Your In-Car Amusement

Posted by on Thursday, 26 May, 2011

Around the world, Car Dvd Players are becoming more and more well-known to many more people, mostly because they can provide ways of listening to music, watching movies and also viewing television stations while driving, that just was impossible a few years ago.

One such method for doing all of the above in many parts of the world is through the use of a tuner known as DVB-T. Knowing what this tuner is can help to answer the question “Car DVD player mysteries: What is DVB-T?”

In short, the above term is an acronym which stands for “Digital Video Broadcasting-Terrestrial”. This is also the industry standard – first developed in Europe by the Digital Video Broadcasting Consortium – for the digital terrestrial television.
This standard, in effect, is the “law” for how digital television can be beamed for receipt at the other end by equipment built to this standard and making use of certain tuners.

The first appeared in 1997 from the UK, and now is recognized standard in many nations of the world and in several countries in South America but not in the U.S.

It allows for the efficient compression and streaming of audio, video and other types of data digitally in what is called the MPEG transport system. The physics behind it can be complicated, so it’s just best to remember that it is a standard for how to transmit information digitally.
A lot of car DVD players and other devices developed to receive and then playing digital music and video are equipped with DVB-T, by the way, although these devices are far more common in Europe and the former British Commonwealth countries than anyplace else.

China and all North American countries use a different Digital Video Broadcasting standard, so the odds are slim that you may see a car DVD player is equipped with this receiver in these regions.
There are several other different digital television and digital broadcasting standards which exist, with many countries allowing for the growth and distribution of car DVD players and other devices that feature not only the tuners, but also DVB-T. North American players and equipment go with what is known as ATSC.

Simply put, DVB-T is different in the way it carries all that data over the air. Many other methods will do so through use of a single radio frequency, while DVB-T does so by splitting all of that data into a very large number of slower digital information streams and then reassembling them at the point of receipt.
There are three different standards for DVB-T in order to know which standard your player, working on can be important, because two of these standards is newer and equipment that uses the older standard players may not work properly or at all interfaces with newer standard players.
When you buy or retail a car DVD player, it may be essential to comprehend how the player how the player handles those signals, as well.

A car DVD player equipped with digital video broadcast capability is all about compression rate, meaning how fast it can squeeze and then decode signals coming from a broadcast source, which will also impact the quality of any pictures displayed.
It is easy enough to figure out the digital video broadcast standard country by going online and afterwards draw up a DVB-T map, or glimpse into product packaging, which will clearly highlight the recipient of the countries where the player is made to function.

How High Is Your Definition?

The enlarging popularity of clear as crystal broadcasts in American TV has indicated that HDTV has arrived and here to stay.

Installing A Digital TV Antenna At Home

Posted by on Monday, 11 October, 2010

As you know, there are several different ways to get digital TV. An antenna is an old-fashioned but still popular way to receive transmissions for digital television. If you live in countries other than the USA, this might be called an aerial in your region. Other ways have been devised to receive digital television. Here is a a short list of TV antenna installation tips that could help you install a digital TV antenna. But if you don’t think you can, it’s better to call someone else to do it.

High antenna installation is best. Installation should be as high as possible. UHF signaling is based on line of sight so the higher you mount your antenna the better. A higher installation means there are less things obstructing the signal between the tower and the antenna. Those who love more than 70 miles away from the TV signal tower must mount their antenna very high by building some sort of tower to place it on.

Install the antenna outdoors. It takes more effort to install the antenna outdoors, but this is necessary. Indoor installation could mean a weaker signal. An outdoor antenna makes all the difference because there are less objects obstructing the signal. The reception of your television will improve dramatically if your antenna is installed outdoors. Sometimes mounting your antenna in an attic can work quite well but again the digital signal will be forced to penetrate a roof before it reaches your antenna. With an outdoor antenna, you might get a few more channels.

Be sure to face the front of the antenna towards the transmitting tower. {Do your research and figure out where the closest TV transmitting tower is. Do some research work, find out where the nearest transmission tower is and be sure to face the front of your antenna toward it. If you are not sure where the nearest antenna tower is, you can search online or go to your signal provider’s website}.

The connectors on your antenna must be sealed so that they don’t corrode. Over time, the antenna connectors will get worn, which could lead to signal loss. The longer the cable runs, and the more splitters the signal must pass through, the more signal loss. Properly ground your antenna to preserve it when there’s an electrical surge. This can be done using a coaxial surge protector. Without this, your antenna is in danger of getting badly burned by lightning.
