4G is the term used to refer to the next wave of high-speed mobile technologies that will be used to replace current 3G networks. The two top contenders are LTE and WiMAX, both of which are IP based networks that are built from similar, yet incompatible, technologies. Sprint and Clearwire are currently offering 4G WiMAX service in the USA, while Verizon and AT&T have committed to the use of LTE and are trialing their own 4G networks.
4G technology is the fourth level of wireless technology available from wireless cellular carriers that utilizes ultra mobile broadband. The first generation of wireless technology available, 1G, refers to the analog signal used by cellular towers. 2G technology upgraded the analog signal to digital and allowed the inclusion of sending text messages across the network. 3G technology made use of electromagnetic wavelengths, known as spectrum, to broadcast a wireless broadband signal that allowed users to access the Internet and download applications using a 3G data card or a handheld mobile device such as a Blackberry or iPhone. 4G technology upgrades further to faster information transfer times, heightened security and greater information exchange abilities.
Ultra mobile broadband refers to the rate of data transmission available on the wireless network. 4G technology may provide data transmission rates between 100Mbps and 1Gbps. For comparison, 3G networks offer data transmission speeds averaging around 200kbps. Network connections on 4G may also be more accurate during travel when user and tower locations are at a constant rate of change—for example, when a user is traveling in a car and signals transfer between towers. This faster, more accurate connection likely can enable the transmission of larger packets of data than 3G networks. Users may be able to access increasingly information-heavy applications, such as HD television signals and real time audio during video chat.

4G wireless service may include modems, netbooks and cell phones. 4G mobile hotspots may offer wireless connections for multiple devices, including computers, netbooks, handheld gaming systems, and mobile phones; with the 4G technology, users may be able to simultaneously download large applications to each device as well. A 4G netbook could operate similarly to a lap top, but with smaller memory and fewer drives; it may offer instant Internet access, downloading, and real-time Web chatting.

4G technology may provide a new wave in downloading capabilities for consumers regardless of which device they choose. Developers have established certain standards for the high performance capabilities of the 4G network; this service may be difficult to provide on on existing cellular towers, however, as they number of users increases. Data transmission slows naturally when there is a large ratio of users to local towers. The United States Congress, with the implementation of digital television, increased available spectrum bandwidth, boosting the networks’ transmission capacity, but such technological improvements may not be enough for a full transition to 4G technology.
