Advantages and Disadvantages of Using 3g Mobile Technology

Posted on by

Over the years, the telecommunications industry has undergone a sea change in terms of the development and use of advanced technologies. One such modern technology is known as 3g mobile technology.

Like other technologies, this one too has its own advantages and disadvantages. Let us explore some of them here.

Considered as an outcome or offspring of the drawbacks witnessed in 2g, this technology is offered at a reduced overall cost by the various carriers.

There is an increased scope for businessmen and developers to use multimedia options, such as videos, graphics and file transfer using advanced techniques like GPRS or Bluetooth.

As the process and rate of data transmission is faster, there is no issue of overcrowding or waiting in queue; making it the next gen platform for mobile enthusiasts.

There is inbuilt facility to accommodate more number of mobile types in the network.

You can avail localized services like news or weather reports.

The video calling technology is improvised in this version, and hence you can arrange conference calls even between people residing in different countries.

Seamless usage of graphs or other kinds of pictures is extremely useful for business persons or developers to exhibit the progress or issues of a particular task.

Due to the speed of data transfer, the number of people patronizing the 3g technology is continuously on the rise. Today, they are able to use social media applications to promote their business right from their handheld devices.

Internet advertisers stand to benefit more due to the high level of mobile usage even for common purposes like music or chat.

There is more bandwidth available to use due to a broader radio spectrum.

Now, moving on to analyze the disadvantages of 3g technology:

The general rate of power consumption is quite high.

The costs involved in setting up base stations or upgrading them is really high, which may not be affordable for all providers.

Moreover, for effective functioning, the base stations have to be established in close proximity to each other.

You have to upgrade your handset or buy a new, advanced one to use 3g technology.

The roaming services continue to have a few drawbacks.

There are some additional costs like the cost of procuring a license and network setup and operational costs.

The basic plan prices are quoted much higher than in 2g even though there are fixed and variable plans available for you to choose from.

The Samsung Galaxy Range was launched almost a year ago and has been diligently added with the latest handsets to keep up its own in the face of intense competition. The range has grown to such numbers that even dedicated Samsung fans do not know which to choose. So let us consider the salient handsets comprising this line and compare and contrast them for better understanding.

The 17500 Galaxy was Samsungs first Android and the first to be launched under the galaxy name. It features 5MP camera with LED flash, GPS, Wi-Fi, 3G and 3.2 Amoled screen. The phone was a great newcomer in the ambitious Android phone market; it still holds its ground quite well. Next up is the second Android phone by Samsung, the I5700 Galaxy Spica. It has 3.2 MP camera, GPS, Wi-Fi, 3G, 3.2 Amoled touch screen and a more equipped Bluetooth than the 17500 Galaxy phone. The third phone is the I5800 Galaxy Apollo which comes with a roughly the same features as the Spica but with the added feature of v2.1 Android Operating System and TouchWiz 2.0. It is also popularly referred to as the Galaxy 3. The I5500 Galaxy 5 was launched at 2010s CommunicAsia trade show along with the Galaxy Apollo but it is lower in its estimations when compared by the latter. It has 2 MP camera, GPS, Wi-Fi and its Android v2.1 with TouchWiz 3.0 is over the top. The I9000 Galaxy S takes the galaxy experience to a whole new level. This is the flagship of the range and with its massive spec sheet and massive screen offers it the massive appeal it rightly deserves. It salient features include 4 AMOLED touch screen with multi-touch and Swype keyboard, Wi-Fi, 3G, HSDPA and HSUPA, GPS, Digital Compass, 5 MP Camera, 8/16 GB Alternative Version and Bluetooth 3.0. All this is topped off with 1 GHz A8 processor, Android v2.1 and TouchWiz 3.0, which makes it one irresistible phone. Samsung Galaxy Ace S5830 another Android Phone with 3.5″ touch screen, TouchWiz v3.0 UI, the social hub app, Think Free Office and 32GB expandable memory. A downright stylish phone of this category is the S5570 Galaxy Pop which showcases a 3.14″ touch screen, Android 2.2 operating system, 3MP camera, A-GPS, Quick Office document viewer, Android music & video player, and a 32GB expandable memory. The I8520 Galaxy Beam provides a healthy but not particularly different alternative to the I9000 Galaxy S. In addition the Samsung Galaxy Tab, The Galaxy S2 and the Galaxy S Pro have added new possibilities to the already multidimensional range.

The Samsung Galaxy Price is quiet nominal when compared to its competitive handsets from rival brands which makes all its features all the more attractive.

Audi Headlight Technology

Posted on by

The new Audi A6 intends to challenge a lot of technology found in its competitor models, one of these innovations is the new all LED headlights. The A6 will be the first executive saloon in the market to have all LED headlights, an optional extra in exchange for the more familiar halogen or bi-xenon lamps that come as standard.

The Audi A6s advanced LED headlight units emit a strong white light that is similar to daylight, and use just 40 watts of electricity each, making them yet another important weapon in the battle against energy consumption. The advanced LED units use just four one-chip and five two-chip LEDs to create dipped-beam light, and 24 white LEDs to make up the daytime running lights in each headlight. This keeps power consumption and maintenance down, and gives excellent life span.

All LED headlights are not new in the Audi line-up, the Audi R8 was the first ever production car to feature all-LED headlights and now are becoming common across the Audi range. The advanced all LED headlights will also be available on the new A7 Sportback and Audi A8 luxury saloon.

The all LED headlights are further enhanced by intelligent systems such as adaptive light control and high-beam assist, which give maximum visibility without dazzling other road users. Simply put the adaptive light system adapts the light provided by the headlights to the driving conditions, with different arrangements of light when driving in the city, country roads and on motorways.

The Audi high-beam assistant automatically varies the range and width of the headlight beam between dipped and full according to the road conditions. The system also incorporates an all-weather function that uses the rear view mirror camera to detect the lights of on-coming traffic and adjust the headlight intensity to give optimum visibility in varying conditions without disturbing other road users.

The Audi A6 is now available to order from Audi Bury St Edmunds, prices start from 30,145 for the 2.0 litre TDI model. The all LED headlight upgrade costs an additional 2,710.

Led Tube light source driver IC needs

The current DC Led Tube light source is a low voltage (VF = 2 3.6V), high current (IF = 200 1500mA) semiconductor devices work, you must provide a constant DC current to the appropriate normal light. Direct current (DC)-driven DC Led Tube light source technology has become more mature, because we use everyday lighting is high-voltage AC power supply (AC100-220V), so the technology must be used to obtain lower step-down voltage, common is a switching power supply step-down, and then alternating current (AC) converted into direct current (DC), then the driver IC can be converted into DC current source to promote Led Tube light shine. Therefore, the DC drive Led Tube light source system application program must be: switching power supply + constant current source. Led Tube must have a certain amount of space inside to accommodate the power supply module, but the E27 standard screw is very limited space, it is difficult placement. Whether through the step-down switching power supply, or other methods, the system will have a certain amount of wear and tear, DC Led Tube in AC, DC conversion between about 8 to 25% of the electricity is loss of efficiency of the system difficult to achieve over 90%. Thereby increasing the power conversion efficiency has been the chip and power supply manufacturers to pursue.
