- 7. About 4G 4G usually refers to the fourth generation mobile communications network that offers speeds that are around 10 times faster than the current third-generation (3G) networks. It can be divided into two broad groups – the Long Term Evolution (LTE) and Worldwide Interoperability for Microwave Access (WiMax). The LTE supports speeds of more than 100Mbps downstream and 50 Mbps upstream while the WiMax is a telecommunications technology that can transmit over much greater distances and handle more data, than the existing WiFi technology.
- 8. 3G vs. 4G When it comes to speed and data handling, the current 3G can transfer data with speeds of up to 2Mbps depending on several different factors. However, users of 4G, WiMax, can expect a much faster data transfer rate of up to 6Mbps and upload speeds of up to 1Mbps although LTE is reported as possessing even greater speeds (100 Mbps and 50 Mbps respectively) theoretically.

Editor's Notes
- The standards in the telecommunications industry are a constantly evolving entity. This happens as technology is advancing the hunger of the public to be able to not just get more content to their portable devices, but to get it there faster. That’s the main driving force behind all of the developments that are happening. At the current moment you could possibly be aware of the fact that almost all of the modernized mobiles as well as the mobile broadband services connect their owners through the 4G networks.As the name infers 3G is the third recognized in the generations of mobile technology. The speeds that you can get through 3G are currently around anywhere from 3.6mbps to 7.2mbps. The speed variations will come from the network provider that you’re will along with the 3G capabilities and coverage of the mobile platform being used to get the 3G signal. Right now, there are quite a number of companies that are working on creating the next generation technology, 4G technologies for mobile networking. Although there are quite a few different companies that are working on the creation of 4G mobile networking and technologies, 4G is a current unified standard of technology. With that there are many different companies that are working on those 4G products that won’t perform on the same manner or even to the same level.
- 4G refers to the fourth generation of cellular wireless standards. It is a successor to 3G and 2G families of standards. A 4G system is expected to provide a comprehensive and secure all-IP based solution where facilities such as IP telephony, ultra-broadband Internet access, gaming services and streamed multimedia may be provided to users.
- Within the United States, there are two major systems using 4G mobile technology. One is known as WiMax and is backed by Clearwire, a firm whose majority owner is Sprint Nextel. It began testing services in Baltimore in 2008 and was set to expand this into major new markets in 2009. Sprint intended to have 80 cities covered by the end of 2010.The rival system, Long Term Evolution or LTE, is backed mainly by Verizon. It was expected to be ready for testing in 2010 but not available for widespread use until 2012. LTE's backers hoped to overcome this disadvantage by offering faster speeds and producing cheaper equipment.Unlike previous generations of mobile technology, 4G mobile will be widely used for internet access on computers as well as carrying cell phone communications. Customers in areas which have strong 4G coverage will be able to use it for a home broadband connection which doesn't require any cabling to their household. It can also be used for accessing the internet on the move without having to be in a wireless hotspot such as those offered by some coffee shops, airports and libraries.
