I am 17 years experienced in field of mobile communications working on 2G, 3G ,4G and 5G systems. Founder of Mega training and consulting since 2014. Working as part time instructor at Egyptian Information technology institute since 2015. Offering systems survey, planning , microwave , transmission and optimization courses. GSM, GPRS, EDGE
Letter E stands for EDGE (Enhanced Data Rates for GSM Evolution). It is also called Enhanced GPRS. This technology lies somewhere in between 2G and 3G technology. So, we refer to it as 2.5G. EDGE
Abstract. The GSM standard developed by ETSI for 2G networks adopts the A5/1 stream cipher to protect the over-the-air privacy in cell phone and has become the de-facto global standard in mobile communications, though the emerging of subsequent 3G/4G standards. There are many cryptanalytic results available so far and the most notable ones In a nutshell, GSM - 2G mobile carrier standard & WCDMA - 3G mobile carrier standardGSM - uses less power & has limited speed on DATA. ( around 144KBps )WCDMA - uses more power & has a good speed on DATA ( around 3MBps ) Choice : Depends on your requirementFor more speed on DATA connection : select WCDMA only modeFor more battery time : select GSM only modeWCDMA preferred mode : This mode is GSM is a second-generation (2G) cellular technology and also an evolution path that uses UMTS for 3G migration and LTE for 4G. CDMA is a multiple access technology which enables the CDMA evolution path in mobile networks that uses IS-95 (cdmaOne) for 2G, CDMA2000 for 3G and LTE for 4G migration. ITU lays down law: WiMAX 2, LTE-Advanced are 4G, everyone else is a buster. ITU capitulates, admits that the term '4G' could apply to LTE, WiMAX, and 'evolved 3G technologies'. Sprint's XOHM WiMAX LTE (4G), GSM (3G & 2G), CDMA (3G & 2G), 5G and ISM. The fundamental differences between these four modern technologies is the way they transmit and receive information. LTE (Long Term Evolution) is a 4G communication standard designed to be 10x faster than standard 3G. the technology provides IP-Based communication of voice and multimedia and knkSJe.
