What does “4G” mean? 4G is a marketing term that service providers are using to describe the “fourth generation” of wireless services.They typically offer between four and ten times the performance of 3G networks.
What technologies run 4G services ?
The two main technologies are Long Tenn Evolution (LTE) and WiMax. The IEEE (Institute of Electrical and Electronics Engineers) developed the WiMax standard; the 3GPP, an industry body for providers that use GSM (the leading technology for cellular communications), heads development of the LTE standard. WiMax and LTE use different types of wireless spectrum.
How fast ls 4G compared with 3G ?
WiMax providers are advertising download speeds of between 2 megabits per second and 6 mbps, with peak speeds of 10 mbps or more. Verizon, which will launch LTE networks in the United States later this year, is expecting to offer services with download speeds in the 5 mbps to 12 mbps range.may also be able to replace your home DSL or cable modem service with a 4G service you can use both at home and on the road.
1. Downlink data rates for 3G in around 2Mbps in stationary mode whilst 4G specifications it should be 1 Gbps and in highly mobile environment 3G downlink speed should be around 384Kbps and 100 Mbps in 4G networks.
2. Multiple access technique to be used by 3G is CDMA and its variations and in 4G both the technologies (LTE and WiMAX) using OFDMA (Orthogonal Frequency Division Multiple Access) in downlink.
3. In the uplink LTE uses SC – FDMA (Single Carrier FDMA) and WiMAX continue to use OFDMA whilst 3G networks use CDMA variations.
