Here there are some growing mobile sectors as
- Cellular platform
- Mobile applications
- Mobile devices
- Mobile operating systems
Now let see what is happening in the above fields
Cellular Platforms
Cellular platforms are circular areas of coverage surrounding elevated transmission gear used to transmit voice and data signals. Increasingly, cellular is being used to distribute data in the form of Web content and various types of messaging. Cellular platforms compete and cooperate with Wi-Fi and 4G - WiMax now and Long-Term Evolution later - offer ways to cut costs and free capacity. If the proposed purchase of Alltel by Verizon closes, the big four U.S. carriers will be Verizon, T-Mobile, AT&T and Sprint. Now the latest technology hosting apex are the 3G,4G and GSM.
3G
3G is a collection of technologies including EDGE, UMTS, HSDPA, and HSUPA that promise to bring high-speed data services to mobile work forces. Progress toward ubiquitous 3G coverage is being made, but competition from rival technologies such as WiMax continues to complicate the market. Many users have rushed to purchase 3G smartphones, and roaming between carriers continues to be a concern. Still, 3G holds enormous promise for users to always be on the cellular network without the security worries of using a wireless hotspot.
4G
4G is the coming IP-based wireless transmission protocol. There are two major players vying for this lucrative market. WiMax is beginning to roll out, while Long-Term Evolution is a couple of years behind but said to have some advantages. Indeed, many players recently have opted for LTE. Eventually, there is nothing to keep the two platforms from merging. Indeed, there is great interest in doing this among both ecosystems as the industry attempts to avoid debilitating standards warfare and competition.
GSM
The Global System for Mobile communications is the most popular cellular approach in the world. According to the GSM Association, there were more than 2 billion GSM subscribers worldwide by June, 2008, which the organization said is more than 86 percent of the world's cellular market. GSM was accelerated earlier this decade by Enhanced Data rates for GSM Evolution (EDGE) and is in the process of further speed boosts by High Speed Downlink Packet Access and High Speed Uplink Packet Access (HSDPA and HSUPA) approaches.
2.Mobile Applications
Mobile applications are the programs that people run on their portable and mobile devices. Developers have taken advantage of increasingly powerful devices and bandwidth-rich networks to provide more highly functional mobile applications. In short, it is possible to perform a great percentage of the tasks in the field that formerly were constrained to the desktop PC. With this new freedom comes considerable security concerns. Sophisticated mobile applications are a competitive must, though.
GPS
GPS, which standards for Global Positioning System, are devices that work with a fleet of medium earth orbiting satellites (MEOS). GPS systems can tell the receiver where it is to within a very small radius. This is done by calculating minute differences in the signals sent to it by the MEOS. GPS was initially developed by the military and can anchor an ever-expanding series of commercial and business location-based services applications.
Mobile Search
Mobile search is the customization of search engines and the way they render their output to support the special needs of untethered devices and users. Mobile search features different results that focus on practical features such as maps and push-to-dial phone numbers. The results are presented in a more stripped-down manner appropriate for mobile devices. Paid results and descriptions may be deleted. The search and mobile industries are aware that mobile search is a vital area.
Location-Based Services
Location-based services, or LBSes, are the transmission of geographically customized information to mobile devices. Location-based services work with the Global Positioning System. For instance, a mobile worker can find a hotspot or business center if he has access to location-based services. These are both useful services for mobile work forces and important value-added services that providers are seeking to monetize.
3.Mobile Devices
Mobile devices are aimed at workers and consumers not working from a wired outlet. The mobile device category is expanding by leaps and bounds, and includes everything from cell phones, feature phones and smartphones to laptops, mobile Internet devices (MIDs), tablet computers and ultra-mobile PCs (UMPCs). Mobile devices are benefiting from the growth of 3G networks and will become even more ubiquitous as 4G grows. There is more diversity in the types of devices and operating systems than in the desktop world.
BlackBerry is a family of smartphones and the related operating system from Research in Motion. The BlackBerry is the most popular business handheld device. When paired with the Blackberry Enterprise Server, the Blackberry enables secure mobile e-mail, voice, Web and other data services. The device, which has earned the sobriquet "crackberry," is under attack from Nokia, Microsoft and others. There is an incipient threat from the iPhone, but so far Apple has sent mixed messages about its attitude toward the corporate market.
iPhone
The iPhone is Apple's foray into the smartphone category. The device was introduced to the AT&T network in June 2007. The latest iteration, the iPhone 3G, was introduced in July 2008 and initially encountered problems. The iPhone is revolutionary for its creative user interface and because it is not being subsidized by the network and vendor, thus driving the price to users higher. The iPhone, which has spawned many competitors, is not essentially aimed at business.
Cell Phones
Cell phones are portable telephones that connect to a mobile network. Increasingly, cell phones are dividing into a trio of categories: basic cell phones, feature phones and smartphones. Cell phones, which also are known as mobile phones, provide many services besides voice calling. These include short message service, location-based services, Web surfing and other data services. In general, phones are getting smaller and the user interfaces more creative. The iPhone has ushered in a new era of creativity.
Smartphones are cell phones with greatly expanded functionality. Smartphone operating systems include Symbian, Linux, BlackBerry and Windows Mobile. The iPhone has stimulated an outpouring of creativity, including individual phones and the birth of the LiMo Foundation and Android, consortia creating plans for vendors to produce open source smartphones and other mobile devices. Security and power issues pose significant threats going forward.
Wireless Handheld Devices
Wireless handheld devices are pieces of equipment light enough to be carried and traffic data over the air. This is a broad area, including various types of cell phones, tablet computers, mobile Internet devices, PDAs and other devices. The increased sophistication of mobile operating systems enables designers to create different devices for different uses. For instance, a medical professional may opt for a tablet while doing rounds, though other options might be able to do much the same things.
4.Mobile Operating Systems
A mobile operating system is the software and code that rests upon the hardware and on which mobile applications interact in order to carry out functions. Mobile operating systems have evolved to create a new category, the smartphone. Smartphone operating systems include Symbian, Linux, BlackBerry and Windows Mobile operating systems. Mobile operating systems must work in the most power-efficient manner. The existence of many mobile operating systems is credited with keeping mobile devices relatively safe from hackers.
Android
Android is the product that will emerge from a Google-led consortium called The Open Handset Alliance. The goal is to use JAVA to create Linux-based smartphones and other devices. The software development kit includes the operating system, middleware and some applications. The alliance includes carriers, manufacturers, device makers and other organizations. It is likely that the first Android devices will be available during the autumn of 2008. Some developers are grumbling about the way the alliance is handling SDK distribution.
Windows Mobile
Windows Mobile is an operating system from Microsoft designed to provide services to a number of computer devices, including smartphones, Pocket PCs and automobiles. The operating system is vying for position as the mobile sector grows due to the expansion of broadband networks and the increasing capacity of handheld devices. Windows Mobile benefits from its ties to other Microsoft products and ability to seamlessly interconnect with Microsoft desktop applications.
Palm OS
The Palm OS is a mobile device operating system featuring a touch-screen based graphical user interface. The Palm OS is or had been licensed to a number of other companies including Acer, Sony and Lenovo. The Palm OS initially was developed in 1996. It has changed hands several times since. In January 2007, current owner Access Co. renamed the operating system the Garnet OS.
Symbian
Symbian is a mobile operating system. In June 2008, majority owner Nokia said that it will buy the 52 percent of Symbian that it doesn't already own and donate it to The Symbian Foundation. At the same time, Nokia said that it will make Symbian open source. The Symbian Foundation has about 30 members, including heavy hitters such as Sony Ericsson, Motorola, AT&T and Texas Instruments. The move by Symbian is characteristic of the intense jockeying for position in the mobile smartphone sector.
