<P> Such devices became especially popular for use with laptop computers due to the added portability they bestow . Consequently, some computer manufacturers started to embed the mobile data function directly into the laptop so a dongle or MiFi wasn't needed . Instead, the SIM card could be inserted directly into the device itself to access the mobile data services . Such 3G - capable laptops became commonly known as "netbooks". Other types of data - aware devices followed in the netbook's footsteps . By the beginning of 2010, E-readers, such as the Amazon Kindle and the Nook from Barnes & Noble, had already become available with embedded wireless Internet, and Apple had announced plans for embedded wireless Internet on its iPad tablet devices later that year . </P> <P> By 2009, it had become clear that, at some point, 3G networks would be overwhelmed by the growth of bandwidth - intensive applications like streaming media . Consequently, the industry began looking to data - optimized 4th - generation technologies, with the promise of speed improvements up to 10-fold over existing 3G technologies . The first two commercially available technologies billed as 4G were the WiMAX standard (offered in the U.S. by Sprint) and the LTE standard, first offered in Scandinavia by TeliaSonera . </P> <P> One of the main ways in which 4G differed technologically from 3G was in its elimination of circuit switching, instead employing an all - IP network . Thus, 4G ushered in a treatment of voice calls just like any other type of streaming audio media, utilizing packet switching over Internet, LAN or WAN networks via VoIP . </P> <P> As well as the now - common cellular phone, there is also the very different approach of connecting directly from the handset to an Earth - orbiting satellite . Such mobile phones can be used in remote areas out of reach of wired networks or where construction of a cellular network is uneconomic . </P>
