that fueled the early growth of the mobile web but was made virtually irrelevant with faster networks, larger displays, and advanced smartphones based on Apple's iOS and Google's Android software. Mobile points of access Mobile Internet refers to Internet access and mainly usage of Internet using a cellular telephone service provider or mobile wireless network. It is wireless Internet access and usage that can easily change to next wireless Internet (radio) tower while mobile user with his/her device is moving across the service area. It can also refer to a desktop computer or other not in move device that stays connected to one tower as using mobile internet, but this is not the prime meaning of "mobile" here. Wi-Fi and other better Internet connectivity methods are commonly available for users not on the move. Cellular base stations are more expensive to provide compared to a wireless base station that connects directly to the network of an internet service provider, rather than through the telephone system. A mobile phone, such as a smartphone, that connects to Internet hypertext data or voice services without going through the cellular base station is not on the service mobile Internet but connected to wireless mobile Internet. A laptop with a broadband modem and a cellular service provider subscription, that is traveling on a bus through the city is on mobile Internet. A mobile broadband modem "tethers" the smartphone to one or more computers or other end-user devices to provide access and usage to the Internet via the protocols that cellular telephone service providers may offer. According to BuzzCity, the mobile internet increased by 30% from Q1 to Q2 2011. The four countries which have advertising impression (?) in total more than 1 billion in one quarter were India, Indonesia, Vietnam, and the United States. As of July 2012, approximately 10.5% of all web traffic occurs through mobile devices (up from 4% in December 2010). 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 on 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. Mobile
