port. Another new class of device appeared subsequently, the so-called "compact wireless router" such as the Novatel MiFi, which makes 3G Internet connectivity available to multiple computers simultaneously over Wi-Fi, rather than just to a single computer via a USB plug-in. 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. 4G – Native IP networks 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. 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, using packet switching over Internet, LAN or WAN networks via VoIP. 5G – Cellular Mobile Communications "5G" is the next version of cellular mobile telephone standards. The 5G standards include millimetre-band radio spectrum to allow data speeds up to 1 gigabit per second, and reduce latency (the processing time to handle a data transmission) between handset and network to a few milliseconds. 5G standards also include low-band and mid-band spectrum similar to existing networks. Telephone companies are introducing 5G technology starting in 2019. Mobile device charger standards Before a universal charger standard was agreed upon in the late 2000s users needed an adapter which was often proprietary by brand or manufacturer to charge their battery. Later, mobile phones from
