Shakira is now officially the Sony Ericsson XPERIA X8

The Android XPERIA line from Sony Ericsson started in 2010 with a big splash in the huge X10, followed by a shrunken Mini duet and now ends the year with a more mainstream XPERIA X8.

Size wise, it sits between the two earlier Android releases but is in some ways better than the X10 Minis. Sporting nothing outstanding, the new XPERIA is pitched to a wider and fashionable market as it will come in various color schemes of dark blue/white, aqua blue/white, pink/white, silver/white and all-white.

Code named Shakira while in production, the XPERIA X8 is powered by a 600 MHz CPU running the same antiquated Android v1.6 Donut OS used in the X10 and should be upgradable to the latest 2.2 Froyo. As a social networker, it has Facebook and an integrated media sharing YouTube as well as Google Talk for IM.

It enjoys a wealth of connectivity options starting with quad band radios on both UMTS/HSDPA on 3G and GSM/GPRS/EDGE on 2G. It comes with WiFi 802.11 b/g, Bluetooth 2.1 with A2DP and microUSB 2.0 for high speed local data connectivity options.
SatNav is supported but its integrated GPS radio with A-GPS and is preloaded with Google Maps/StreetView and Wiseplot on free trial. There are some really nice Xperia X8 contracts from online stores and you should compare them together before purchasing your next mobile phone.

The XPERIA X8 sports a 3-inch TFT capacitive touchscreen with half-VGA resolution, 16 million colors, a scratch-resistant glass and an accelerometer. There’s a 3.2 megapixel fixed focus camera with geo tagging and VGA video recording at 30fps.

Without boasting any Walkman legacy, the XPERIA X8 is no less a capable music phone. It is in fact better than many as it has a 3.5 mm headphone jack that some Walkman phones miss out.

It has the requisite stereo FM radio with RDS and multimedia players for popular audio and video files. You also get the signature Sony Ericsson TrackID and PlayNow apps. Your multimedia files get served, not by its 128 MB internal memory, but by its support for up to 16 GB microSD cards. Its sales kit includes a 2GB microSD card.

Mobile gaming

Modern mobiles support a lot of games meant for entertainment purposes. The concept of gaming on mobiles was introduced in the year 1997 by Nokia on selected models. “Snakes” was the first game to be played on the mobile phone and “Bricks” was the next game to be played on the mobile. Games like Tetris, Poker, Space fighters are common on mobiles. The field of Mobile Gaming experienced a growth after the introduction of color mobiles. Mobile games are available pre-installed on old dated models (esp. Monochromatic models) and advanced models provide the scope of installing more games. The modern mobiles support multiplayer, networking games that can be played by multiple players using connection standards like Bluetooth, Infrared, Wi-Fi etc.  Mobile games are developed using mobile application development technologies like .Net Compact Framework, J2ME etc. The concept of gaming is more popular in PC’s and more people involve in PC gaming, due to this the mobile games seem to be much lesser in usage than PC games due to various factors like small screen, limited resources, lack of high quality graphics etc. But after the introduction of Smartphone, the domain of mobile gaming is getting more attention as Smartphone posses advanced architecture than normal mobiles.

sim

SIM stands for Subscriber Identity Module. It is a smart card being used on the GSM standard mobiles phones to uniquely identify the user. All the details that the mobile network service provider must know about the user are contained in the SIM card only. This feature enables the users to change their mobiles by simply removing his SIM card from one mobile and plugging it into another mobile. The SIM cards are designed on the lines of ISO defined Smart Card standard, ISO/IEC 7812. The first ever SIM cards were developed at Munich, Germany by Giesecke and Devrient in the year 1991. Each and every user has a unique number contained in his SIM. This number is known by the term IMSI (International Mobile Subscriber Identity). This IMSI is fifteen digits long number which can also has information about service provider’s network code and his country code. This number is used by the service provider to contact and communicate with the mobile phone via SIM. Most of the SIM cards along with the above information also provide memory space for the user to store his SMS messages and contacts. About two hundred and fifty contacts can be stored on a single SIM.

gsm

GSM originally means Group Special Mobile, now it is widely denoted using the expansion, Global System for Mobile Communications. It is one of the most popular mobile communication standards. About 80% of the mobiles round the world run on this standard. Three billion people around the world use this standard. The idea of GSM was stormed in European Conference of Postal and Telecommunication Administration for a telephone system that can be used all over the Europe.  GSM fully employs digital signals for all sorts of communication. It was introduced during the 2G. Though it was introduced during 2G, GSM supports services like GPRS, EDGE etc. This standard introduced a most helpful service known as Emergency Telephone Number. It is a single emergency number, 112 which is supported all over the world. Based upon the coverage area, GSM uses five different cell sizes. The GSM mostly works in 900MHz and 1800MHz frequency. But this could well vary with the geographical locations. GSM employs a guard space of 45MHz between its uplink and downlink channels. However GSM suffers a major setback, the GSM signals interfere with the audio devices nearby and produces noise in it. It requires costly mechanism to prevent this interference.

Mobile phones and Mobile communications are also known as Cellular phones and Cellular communications. These names are derived from the abstract cells that are built for the mobile communication. For installing mobile communication in the given physical geographic location, the location is divided into pieces of continuous area known as cells. In each cell, a base station is installed. In other words, now in base station’s point of view the cells can be defined as the area around the base station where its influence is witnessed in mobile phones. This base station is responsible for the maintenance and providing the services for the mobile phones within its cell. The size of the cell can vary with the population of the mobile phones in its area. It can cover a hundreds of kilometers in remote areas to few hundreds of meters in thickly populated areas. So many a numbers of cells must be implemented in a city for uninterrupted coverage. As the name mobile implies, it is obvious for the mobile phone to change its location in the cell’s radar. Once a mobile phone leaves a cell and enters another, it now comes under the influence of another base station. This thing is known as Handove

4G

The next generation that is being expected in the field of mobile communication is 4G or the next generation. This generation is expected to completely change out the existing system. It aims for the introduction of an IP based communication in the sector. This generation is defined to produce high data rate of 100 Megabits per second along with the most efficient spectral efficiency than its ancestors.  This generation is also expected to produce smooth handoffs among cells. Initially for implementing this 4G, various technologies like IEEE 802.16e, Flash-OFDM etc. were considered, but these technologies were not fully sufficient to incorporate all the 4G features. Now a blend of various technologies like MIMO (Multimedia), Turbo Principle, OFDM are in consideration. Also CDMA (Code Division Multiple Access) could end up as the most favorable access scheme for 4G due to its spectral efficiency. The recent advanced FDMA (Frequency Division Multiple Access) schemes are also in race with the CDMA. 3G was based on both circuit and packet switching, but 4G is based purely on packet switching only. So it extensively uses IPv6 for data transmission. 4G will certainly be a boom in mobile communications because with the data rate it provides, a movie could be downloaded in 5 minutes!

3G

The 2G was superseded by 3G then. Between these two generations, an intermediate generation namely 2.5G was also observed. 2.5G is also known as the stepping stone between these two generations. In addition to the services provided by the 2G, 2.5G provided another service namely GPRS. GPRS stands for Global Packet Radio Service, which is a packet oriented data service which helped to upgrade the data services provided by GSM in the 2G. The next came the 3G generation, this generation used the bandwidth more efficiently that its ancestors. It was the first generation to provide high speed internet access and video telephony to the users. The migration from 2.5G to 3G was brought down in two steps. 2.5G to 2.75G and then the 2.75G to 3G. The addition of another service known as EDGE brought down the transition from 2.5G to 2.75G. EDGE stands for Enhanced Data rates for GSM Evolution. It drastically improved the data transmission rates and it was deployed on GSM mobile for the first time on 2003. After the arrival of such services, there arrived a need to standardize them; the system designed for this purpose is abbreviated as UMTS. UMTS stands for Universal Mobile Telecommunications System. The addition of UMTS standard marked the beginning of 3G.

2G&1G

Since from its birth, the mobile phones have witnessed three generations and the fourth generation of mobile phones is being expected. These generations are abbreviated as 1G, 2G, 3G and 4G respectively. The first generation of the mobile phones was introduced in the 1980’s. The 1G was replaced by 2G. The phones during 1G used the older analog telecommunication standards for communication. 1G was soon replaced by 2G communication. 2G service was started on 1991 in Finland. In 2G all the communication channels were digitalized. Digital systems provided much for data integrity and security. In 2G in addition to voice transaction, data service was also started. In other words this service is known as Short Message Service (SMS)! Time (TDMA) and Code (CDMA) multiplexing techniques were used in 2G. GSM and cdmaOne were the most used standards then. GSM was in practice in Europe and cdmaOne technique was observed in use in the lands of America and Japan. Excluding these two, three more minor standards were also used then. 2G provided a lot of advantages over its predecessor 1G in terms of bandwidth efficiency and more security. It was the first time when services like mail, SMS were witnessed on the phones.

I PHONE

IPhone is a Smartphone introduced by Apple Inc. in the year 2007. It is the most popular and most sold Smartphone in the world. Till now about twenty two million units of iPhones have been sold all over the world. It is designed on “bar” form, with iPhone OS (developed by Apple exclusively for iPhones). It has a maximum of 32 GB flash memory with 128 MB DRAM. I Phone houses various connectivity devices like Wi-Fi, Bluetooth, GPRS and EDGE. It has a 3.5 inch wide screen with two mega pixel camera. Initially it is supposed that iphone is to be developed by the joint effort of Apple and Motorola, but afterwards Motorola broke away and Apple took the full stake over the development. Iphone has a touch sensitive LCD (Liquid Crystal Display) screen and it was the first mobile to introduce multi touch sensing screen. It runs on iphone OS, which is a derivative of Darwin operating OS found in Mac OSX Leopard.  It supports audio conferencing and visual voice mailing, but it doesn’t support video calling. Iphone lacks an inbuilt keyboard and a virtual keyboard over the touch screen is present. IPhones almost have all the browsing capabilities, multimedia functionalities of a PC!
