CDMA Mobiles creating revolution in mobile technology

Posted on by blogger

CDMA technology is lesser used technology amongst the two i.e. GSM and CDMA. There have been two major network-providers Tata and Reliance. Recently, MTS has also joined hands with them and has come out of lucrative schemes to create a revolution in competition.

CDMA or Code Division Multiple Access is as smart a technology as GSM mobile networking. Originally known as IS-95, it was developed by Qualcomm and enhanced by Ericsson. It is characterized by small radius but high capacity. CDMA is a form of spread-spectrum signaling and its modulated coded signal has much higher bandwidth than communicated data.

CDMA technology is lesser used technology amongst the two i.e. GSM and CDMA. There have been two major network-providers Tata and Reliance. Recently, MTS has also joined hands with them and has come out of lucrative schemes to create a revolution in competition.

Companies like Samsung, Motorola, LG, etc have been targeting their customers with attractive prices and schemes. An average CDMA handset is very cheap and usually come with cheap connection prices. Initially they could not create their market-hold, due to their lesser subscribers. But now, they are as popular as GSM mobiles.

This technology is more popular in suburbs and villages, where the cost of operating a CDMA handset is quite low. In one such scheme, talking from mobile to mobile with same service provider was almost negligible and hence quite affordable. On the other hand, users have to invest in mobile and connection both for utilizing this service.

Mobile services have improved upon their network and this is the treason that almost every second person utilizes the services with quite an ease.

CDMA handsets are present in all range, from entry level to premium categories. Samsung CDMA handsets are sleek, stylish, and provide its customers full value for money. Similarly Nokia CDMA handsets are trust-worthy and reliable in their approach.

CDMA handset are more popular now days. They can be installed easily and are quite less costly on pockets. Since everyone wants to reduce cost of operation, so they are shifting to CDMA mobiles from much popular GSM connections. Those who have been maintaining a number for professional purposes are opting for another connection to make their calls almost negligible in cost.

The major three players including Tata, Reliance and MTS will give a run to other network-subscribers. Users can reduce their mobile bills by simply making calls from CDMA mobiles.

Directv Trusts On Spot-beam Technology To Retransmit More Local Channels

Posted on by blogger

It’s important to note that satellite has been less successful in carrying local channels than the traditional cable system has. This shows some distinction between presenting local signals on a national satellite platform versus a local cable television system.

A normal cable tv provider simply collects over-the-air transmission signals from the surrounding area and broadcasts those signals to its subscribers. Therefore, a cable TV system usually retransmits ten to fifteen transmission signals at a time. DirecTV should retransmit more local channels from a single satellite constellation; the satellite works like the cable TV transmission office. Now-a-days, simultaneously, DirecTV retransmits the signals of more than 1000 local channels. This needs a massive quantity of capacity and this has been the most important engineering challenge DirecTV has faced over the past couple of years.

DirecTV came across this challenge by utilizing the spot-beam technology. First, DirecTV has launched spot-beam satellites that produced extra capability by reusing spectrum in various geographic areas. The CONUS-beam satellites have a single, multi-frequency footprint that focuses the complete area of the United States. At the same time as CONUS satellites are exceptional for retransmitting national programming, employing those satellites to retransmit local transmission programming is a very extravagant use of spectrum. Obviously, if one was trying to retransmit local channels in all markets all over the country through CONUS satellites, the capability on the satellites would rapidly be drained leaving petite, if any space for national cable programming. In contrast with the CONUS-beam satellites, spot-beam satellites are good enough for the retransmission of local transmission signals. This is possible, because, instead of looking the complete United States with a more number of transponders, the spot-beam satellites cover multiple, separate areas, each with only one or two transponders. Thus, the spot-beam satellites allow the geographic reuse of satellite frequencies. By looking separate and non-overlapping geographic areas, the spot-beams of the satellites can achieve much the same thing.

Secondly, the other technology employed to boost the capacity is compression, which is a technique for mathematically manipulating data to get rid of superfluous and unnecessary bits. During the early 1990s, the compression rates were approximately 5:1. However, now-a-days, for SD TV signals, the compression rates are normally between 11:1 and 12:1, and further developments are going on. DirecTV satellites possess a spot beam accompanying two transponders covering the area close to Washington, DC. By 12:1 compression, the retransmission of all the 12 analog broadcast stations of Washington in SD format can be achieved at the same time leaving extra capacity to carry the local signals in the other markets covered by the same spot beam. However, if DirecTV does not use compression for transmission, it would require a complete transponder to every station.

The capacity of a satellite operator to retransmit the local transmission signals in a specific market is not depends on how many transponders the satellite operator employs; however, it is important that how many transponders are obtainable in the spot beam covering that market. It is also essential that how much the satellite operator is proficient to compress the transmission signal at the same time maintaining the quality of the signal.

Canvas printing and technology

Posted on by blogger

In thy last few years inkjet technology has come a long way which is great for those interested in canvas printing. This means that companies that specialise in canvas printing can offer your pictures and artwork printed on canvas at low cost effective prices. This also means when printing your pictures on to canvas your image can be reproduced with great quality with your picture looking great. With the improvements most images can be enlarged to a1 and in some cases allot bigger without distorting the original image.

For canvas printing the ideal inks are as follows pigment, uv and solvent, solvent being the best for canvases that would b displayed outdoors, all of these are light fast 75 years meaning that they can be displayed in direct sunlight without fear of it fading. Most dye based inks are not suitable for canvas printing these will fade with uv light even indoors if a window is present, some may claim they are lightfast but this is only true when placed behind uv protected glass. Some photos are not ideal for canvas printing as they may have image mater edge to edge so u may lose some of the image when you come to wrap the canvas round the frames. There are a variety of methods to solve this problem this is where photo shop can be very useful. If the image is lost when wrapping round the frame one option is to have your image on the face which you will have your image on the front of the frame and not going round the sides most chose to have plain white sides when using this method but if you would so like you can have the sides in whatever colour you like. Another way around this problem is to use an effect called mirroring where you duplicate the image round the sides so it blends in but you don’t lose any of the original images.

Another great tool you can use in photo shop is red eye, when you have taken a photo of friends or family often you get a bad effect called red eye where the eyes appear to be red most people would think these photos are not any good for turning into canvas prints which is wrong as even with the basic photo shop this can be easily corrected restoring eyes back to their original colour.

Canvas printing can be an easy process but only if you have the right tools and the right experience. if you don’t have these then I would recommend that you seek either expert advice or to hire a professional printer to print and frame your work for you. This way you know that the job will be done correct with the right materials and the right approach and view you would expect a canvas print to be. Then all there is left for you to do is decide where to hang your beautifully made canvas print
