2nd GENERATION:Digital cellular systemsDigital modulation schemes- TDMA,CDMAData speed in 2g is up to 64kbpsData speed in 2.5g is up to 144kbpsGPRS, EDGE and CDMA 2000 were2.5 technologies.
3rd GENERATION: 3g technology is intended for true multimedia cell phone typically called smart phones and features increased bandwidth and transfer rates to accommodate wed-based applications and phone-based audio and video filesAdvantagesuniversal global roaming multimedia (voice , data & video)384 kbps while moving2mbps when stationary at specific l locationsvideo calling
4th GENERATION: high-speed data accesshigh quality streaming videocombination of wi- fi andwi-maxSDR,OFDM,OFDMAand MIMO
WHAT IS 5G??? 5G is a packet switched wireless system with wide area coverage and high throughput.5G wireless uses OFDM andmillimeter wireless that enablesdata rate of 20 mbps andfrequency band of 2-8 GHz.5G is going to be a packedbased network.
OBJETIVES OF 5G: 5G being developed to accommodate QoS rate requirements set by further development of existing 4G applications. Flexible channel bandwidth between 5 and 20MHz, optionally up to 40MHz. Data rate of at list 1Gb/s between any two points in the world. Increase system spectral efficiency of up to 3bit/s/Hz/cell in the downlink and 2.25bit/s/Hz/cell for indoor usage.
STANDARD WIRELESS 5G: WiMAX formed to provide conformance and interoperability of the IEEE 802.16 standard. It aims to provide wireless data over long distance from point-to-point link to cellular mobile type access. WiBRO a part of IEEE 802.16e in process to provide collaborative and generic mobile WiMAX. 3GPP LTE a project aims to improve the mobile phone standard to cope with future requirements. 5GPP 2 UMB a project to improve the CDMA2000 mobile phone standard for next generation applications.
5G NETWORK REFRENCE MODEL:
IPv6 SUPPORT: IPv6 increases the IP addresses size from 32bit to 128 bits, to support more levels of addressing hierarchy and much greater number of addressable node. IPv6 support large number of wireless enabled devices. IPv6 Extend the IP address space enough to offer a unique IP address to any device. IPv6 Improve support for IP Mobility.
