Windows Phone OS Vs. Android OS

Windows operating system is the undisputed king in the world of computers, it is the kingpin. But when it comes to the mobile phones the scenario is not that bright. Windows has to make space for itself in the presence of two giants: iOS and Android.

Android vs Windows

The Windows Phone OS is a relatively new player in the world of mobile handsets. It is approximately two years old in the market, and as far as the mass use of the OS is concerned, it appeared at the Mobile World Congress 2011 with the Nokia handsets, the Lumia series. And with the Nokia Lumia 800 and Nokia Lumia 710 the Windows Phone OS was supposed to take off, but somehow it did not respond accordingly to the high anticipation of the tech world. Let’s find out how and why it lags behind the giant Android.

First and the foremost reason is like the Android, Windows does not enjoy the flurry of vendors who give the users a wide range of choice, all the way from 3000 bucks to the 40000 upper crust. Windows phones are only for the thick walleted folks. And it is simple; number of handsets sold is directly proportional to the number of operating systems in the market.

Second and equally important thing is the Windows OS does not come up with something new all the time, which the users demand at the time of purchasing a handset. Yes, it has the Metro UI but that is a complex thing, not meant for the common place people. On the other hand Android comes up with a new app every now and again (no matter useful for the users or not) to woo the purchaser.

Android vs Windows7

One more thing that needs to be emphasized is that the companies like Nokia, HTC, and even Samsung offer only two or three handsets that run Windows Phone OS that not just cramps the users for choice but they are not stylish and trendy handsets. If we look at Samsung, we find that the Android handsets are far better looking than the Windows phones.

The foresight that Google invests in the Android is commendable, after the super success of the ICS 4.0 is already planning to unveil the Android 5.0 whereas the Windows OS is still holding on to the 7.5 Mango.

And the story is the same for the Windows based tablets. I would like to say that the road is far more difficult here than in the handset sphere where the monster called Apple is as well established as God in heaven. Though, there is some hope for the Windows after the release of the Windows 8, but the hope is now looking like a thin shadow of something that is not confident of its own success. Let us see what happens.

4G LTE Standard

Well, the time we are living in is a time of evolution; at least in the world of technology and in the field of telecommunication the speed of advancement is a little quicker. There was a time just a year or so ago when the 3G technology was supposed to be the hot and happening achievement of technological persuasion but then, it became cold as soon as the new term 4G LTE surfaced at the horizon. Let us find out what exactly the 4G LTE is.

4G LTE Speeds

The term LTE stands for Long Term Evolution, it happens to be a wireless data communication standard that came out to light because of the Third Generation Partnership Project ie.3GPP. It has been designed to give the users ten times the speed of a 3G network for all the 4G enabled devices including mobile phones, tablets, ultraslim laptops, and wireless laptops. The 4G has been designed keeping an eye on the data communication at 1 Gbps.

There are several 4G standard and LTE happens to be one of them. Other standards are Ultra Mobile Broadband (UMB) and WiMax. All around the world the top guns of mobile service providing are battling hard to come up with the 4G technology; a few have been successful and others are trying their utmost to come up with the 4G. Verizon and AT&T have launched the 4G LTE whereas Sprint has come out with the latest 4G WiMax network. The highest download speed on 4G LTE is around 100Mbps and the Upload speed is 50Mbps.

Unlike the previous technologies where traditional data transfer is done, the 4G uses IP packet switched networks for the purpose. All the major carriers like the LTE standard because it supports bandwidth of 1.4 Mhz to 20 Mhz(which is quite flexible), Frequency Division Duplex and Time Division Duplex. That is not all, the standard has a provision for backward compatibility with older networks namely GSM, UMTS, and CDMA.

Though 4G is still a phenomenon that occurs in the developed nations but its rapid growth suggests that it will not take too long to hit the developing nations. It is here and it is here to stay.

The Path of Evolution for the Mobile Phone Batteries

The telecommunication market is humongously swollen with different types of mobile handsets. Obviously, the makers, in their quest to gain advantage over the other players of the field, advertise various features of their products; some concentrate on the display, some on the camera, similarly, some on the looks. Very few of them have been found to be advocating the battery features of their respective handsets. One thing here need to be emphasized that no matter how good your handset is it will be functioning as a meek and submissive handset if the battery feature is not up to the mark.

There are several types of batteries as there are different types of handsets in the market. The material used in the making of the batteries and the technology applied are the two main distinction as far as the type of batteries is concerned.

Li-ion Battery for Mobile Phones

When the mobile handsets came into the market for the first time they had Nickel Cadmium batteries. These batteries had the capability to get recharged after being exhausted and had a good battery life, and what more they were relatively pretty small in the physical size. But it had issues with charging where it used to create a memory if recharged without being completely discharged and hence the performance was diminished.

After that the Nickel Metal Hybrid batteries arrived, which were a slight variation of the previous Nickel Cadmium batteries. But this too was not proved to be up to the mark.

Then came the Lithium Ion batteries, which, in fairly short period of time, acquired huge success as the ultimate mobile phone battery. They have valid reasons for getting the thunderous success that they have achieved; the Li-Ion batteries are long lasting, have no memory effect, and they are light weight and powerful. Yes, they are a little averse to the cost effectiveness but they make up for that by their performance and longevity. They are compatible with all kinds of cell phones. Yes, at times, they tend to become a little problemetic with their swelling tendencies but that is an issue that can be taken care of by using the batteries with a little added care.

Li-Polymer battery for mobile

The latest entry on the mobile phone battery horizon is the Lithium Polymer aka Li-Polymer battery. Most of the recently launched smartphones sport Li-Polymer batteries. But none of the old handsets which need the battery change accept the Li-polymer batteries. But the new age smartphones that come with hefty price tag come with this battery type and work excellently.

It is quite sure that the modern technological advances will come with newer battery types which will be more effective and efficient, but for now the Li-Ion and Li-Polymer batteries are the best!

How A-GPS enhances GPS performance

Global Positioning System (GPS)

Global Positioning System (GPS) is a space based satellite system for direction-finding. The system was developed and is operated by the United States Department of Defense to determine current location, time and velocity of places. A cluster of 24 Earth-orbiting satellites and their ground stations are used in calculating accurate location and time information anywhere on the Earth. Three more satellites are available to be used in case of failure of functional satellites. The first GPS satellite was launched in 1974 and the 24th satellite, which is the latestworking station, was launched in 1994. With the advancement of technology, the cost of GPS devices has tumbled while the accuracy of location has been achieved and even the system has been incorporated in handheld devices.

A GPS receiver is a combination of an antenna – to tune frequencies transmitted by the satellites, receiver, processors, and a highly stable clock.  It calculates position by accurately timing the signals sent by GPS satellite positioned above the Earth. Satellites continually transmit specific orbital information and the timing of the message transmitted. Receiver uses the messages to determine the transit time and computes the distance to each satellite to provide exact position of the receiver. The position is displayed on the receiver with a moving map or in form of latitude and longitude. Modern GPS units also derived information such as direction and speed, calculated from position changes.

GPS vs A-GPS

Global Positioning System (GPS) needs to find orbit and clock data for the relevant satellites, which is termed as the time to first fix” (TTFF) to pin point the accurate locations. It takes anywhere from 30 seconds to a couple of minutes to acquire a signal depending on your location, amount of interference and horizon information as satellite receiver is based on line of site mode. On the other hand, the whole process is very faster in assisted GPS (A-GPS) devices. Cellular network towers have GPS receivers or a base station in nearby location to pull down satellite information and compute the data constantly. The data is transmitted to the cellular phone on demand.

Thus, A-GPS improves the performance of the GPS. With a GPS, one can track location indoors or non-optimal environmental settings which cannot be done with a GPS device which is limited by line of sights.

A-GPS (Assisted GPS)

A-GPS boosts the reception signals of GPS receiver using assistance from other services. It is the technology, which is to be credited for introduction on GPS system in cellular devices such as mobile phone.

Here’s how A-GPS boosts the performance on an ordinary GPS receiver:

A-GPS helps GPS receiver to quickly obtain the time to first fix” (TTFF) – the measure of the time required for a GPS receiver to acquire signals and navigate data via the cellular network and avoid downloading the information via satellite, which is a slow process.

GPS uses an unobstructed line of sight to four or more GPS satellites to determine location. Signals may be obstructed by buildings as they cannot penetrate building interiors. In such cases, A-GPS uses proximity to cellular towers and calculate positions. It addresses signal and network problems by using assistance from other services such as GPRS and service provider network. Thus, A-GPS enhances GPS performance.
