The Mobile Web refers to the use of Internet-connected applications, or browser-based access to the Internet from a mobile device, such as a smartphone or tablet computer, connected to a wireless network.
Traditionally, access to the Web has been via fixed-line services. However, the Web is becoming more accessible by portable and wireless devices and in 2008 mobile access to the Internet exceeded desktop computer-based access for the first time (source: International Telecommunications Union, Oct 2009).[1] The shift to mobile Web access has been accelerating with the rise since 2007 of larger multitouch smartphones, and of multitouch tablet computers since 2010. Both platforms provide better Internet access and browser- or application-based user Web experiences than previous generations of mobile devices have done.
The distinction between mobile Web applications and native applications is anticipated to become increasingly blurred, as mobile browsers gain direct access to the hardware of mobile devices (including accelerometers and GPS chips), and the speed and abilities of browser-based applications improve. Persistent storage and access to sophisticated user interface graphics functions may further reduce the need for the development of platform-specific native applications.
Mobile Web access today still suffers from interoperability and usability problems. Interoperability issues stem from the platform fragmentation of mobile devices, mobile operating systems, and browsers. Usability problems are centered around the small physical size of the mobile phone form factors (limits on display resolution and user input/operating). Despite these shortcomings, many mobile developers choose to create apps using Mobile Web. A June 2011 research on mobile development found Mobile Web the third most used platform, trailing Android and iOS.[2]

'Mobile Internet' refers to access to the Internet from a mobile device, such as a smartphone or laptop via integrated abilities or via an independent device (such as a USB modem or PCMCIA card).
Today USB modems are HSPA (3.5G) modems. Many users "tether" their smartphones to their laptop or personal computer with the wireless device providing access to the Internet via 3G, GPRS or CSD.
According to BuzzCity, there's a 30 percent increase of mobile internet in a quarter from Q1 to Q2 2011. The four countries that have advertising impression in total more than 1 billion in one quarter were India, Indonesia, Vietnam and United States.[3]
Standards improve the interoperability, usability, and accessibility of mobile web usage.
The Mobile Web Initiative (MWI) was set up by the W3C to develop best practices and technologies relevant to the Mobile Web. The goal of the initiative is to make browsing the Web from mobile devices more reliable and accessible. The main aim is to evolve standards of data formats from Internet providers that are tailored to the specifications of particular mobile devices. The W3C has published guidelines for mobile content, and is actively addressing the problem of device diversity by establishing a technology to support a repository of device descriptions.
W3C is also developing a validating scheme to assess the readiness of content for the mobile web, through its mobileOK Scheme, which will help content developers to quickly determine if their content is web-ready. The W3C guidelines and mobile OK approach have not been immune from criticism. This puts the emphasis on Adaptation, which is now seen as the key process in achieving the ubiquitous web, when combined with a device description repository.
mTLD, the registry for .mobi, has released a free testing tool called the MobiReady Report (see mobiForge) to analyze the mobile readiness of website. It does a free page analysis and gives a Mobi Ready score. This report tests the mobile-readiness of the site using industry best practices and standards.
Other standards for the mobile web are being documented and explored for particular applications by interested industry groups, such as the use of the mobile web for the purpose of education and training.
The first access to the mobile web was commercially offered in Finland in 1996 on the Nokia 9000 Communicator phone via the Sonera and Radiolinja networks. This was access to the real internet. The first commercial launch of a mobile-specific browser-based web service was in 1999 in Japan when i-mode was launched by NTT DoCoMo.
The Mobile Web primarily utilises lightweight pages like this one written in Extensible Hypertext Markup Language (XHTML) or Wireless Markup Language (WML) to deliver content to mobile devices. Many new mobile browsers are moving beyond these limits by supporting a wider range of Web formats, including variants of HTML commonly found on the desktop Web.
The .mobi sponsored top-level domain was launched specifically for the mobile Internet by a consortium of companies including Google, Microsoft, Nokia, Samsung, and Vodafone. By forcing sites to comply with mobile web standards, .mobi tries to ensure visitors a consistent and optimized experience on their mobile device. However, this domain has been criticized by several big names, including Tim Berners-Lee of the W3C, who claims that it breaks the device independence of the web: 1
It is fundamentally useful to be able to quote the URI for some information and then look up that URI in an entirely different context. For example, I may want to look up a restaurant on my laptop, bookmark it, and then, when I only have my phone, check the bookmark to have a look at the evening menu. Or, my travel agent may send me a pointer to my itinerary for a business trip. I may view the itinerary from my office on a large screen and want to see the map, or I may view it at the airport from my phone when all I want is the gate number. Dividing the Web into information destined for different devices, or different classes of user, or different classes of information, breaks the Web in a fundamental way. I urge ICANN not to create the ".mobi" top level domain.
Since the first ringing tone was sold on the mobile phone in Finland in 1998, the mobile has emerged as the seventh of the mass media. Today a wide range of paid media content is consumed on mobile phones ranging from 9.3 billion dollars of music and 5 billion dollars of videogaming to horoscopes, virtual gifts, jokes, news, adult entertainment, etc. Also like on all other media, advertising appeared onto mobile when a free news service launched in Finland sponsored by ads in 2000.
In 2005, The Crazy Frog ringtone became the first mobile ringtone to cross over into the mainstream music charts, beating Coldplay for the Number 1 spot on the UK charts.[4]
Advertisers are increasingly using the mobile Web as platform to reach consumers. The total value of advertising on mobile was 2.2 billion dollars in 2007. A recent study by the Online Publishers Association reports that about one-in-ten mobile Web users said they have made a purchase based on a mobile Web ad, while 23% said they have visited a Web site, 13% said they have requested more information about a product or service and 11% said they have gone to a store to check out a product.
Though Internet access "on the go" provides advantages to many, such as the ability to communicate by email with others and obtain information anywhere, the web, accessed from mobile devices, has many limits,[5] which may vary, depending on the device. However, newer smartphones overcome some of these restrictions. Some problems which may be encountered include:
The inability of mobile web applications to access the local capabilities on the mobile device can limit their ability to provide the same features as native applications. The OMTP BONDI activity is acting as a catalyst to enable a set of JavaScript APIs which can access local capabilities in a secure way on the mobile device. Specifications and a reference implementation[7] have been produced. Security is a key aspect in this provision in order to protect users from malicious web applications and widgets.
In addition to the limits of the device, there are limits that should be made known to users concerning the interference these devices cause in other electromagnetic technology.
The convergence of the Internet and phone, in particular has caused hospitals to increase their mobile phone exclusion zones. A study by Erik van Lieshout and colleagues (Academic Medical Centre, University of Amsterdam) has found that the General Packet Radio Service (GPRS) used in modern phones can affect machines from up to 3 meters away. The Universal Mobile Telecommunications System (UMTS) signals, used in 3G networks, have a smaller exclusion zone of just a few centimeters. Not surprisingly, the worst offenders in hospitals are the doctors.[8]
