5th generation mobile networks or 5th generation wireless systems is abbreviated as 5G, and proposed next telecommunications standards beyond the current 4G/IMT-Advanced standards. 5G planning aims at higher capacity than current 4G, allowing a higher density of mobile broadband users, and supporting device-to-device, ultra reliable, and massive machine communications. Its research and development also aims at lower latency than 4G equipment and lower battery consumption, for better implementation of the Internet of things.
Enhanced Data rates for Global Evolution (EDGE)Ramrao Desai
Mobile users continue to demand higher data rates. With the continued growth in cellular services, laptop computer use and the Internet, wireless network providers are beginning to pay an increasing amount of attention to packet data networks. Enhanced Global Packet Radio Service (EGPRS) offers a substantial improvement in performance and capacity over existing GPRS services, in return for a relatively minimal additional investment. EGPRS, commonly called EDGE, achieves these enhancements to the GPRS system primarily by implementing changes to the Physical layer and to the Medium Access Control/Radio Link Control (MAC/RLC) layer. The significant improvements are a new modulation technique, additional modulation coding schemes, a combined Link Adaptation and Incremental Redundancy technique, re-segmentation of erroneously received packets, and a larger transmission window size.

Andreas Roessler is the Rohde & Schwarz Technology Manager focused on UMTS Long Term Evolution (LTE) and LTE-Advanced. With responsibility for the strategic marketing and product portfolio development for LTE/LTE-Advanced, Andreas follows the standardization process in 3GPP very closely, particularly on core specifications as well as protocol conformance, RRM and RF conformance specifications for device and base stations testing. He graduated from Otto-von-Guericke University in Magdeburg, Germany, and received a Master's Degree in communication engineering.
As we celebrated 25th anniversary of WWW last year I put together a few major events that made the web what it's today- a platform used by over 3 billion people worldwide. This is the evolution of the World Wide Web in a few short slides.

Presentation on 1G/2G/3G/4G/5G/Cellular & Wireless TechnologiesKaushal Kaith
This Presentation is explaining all about the Generations of Mobile or Cellular Technology (1G/2G/2.5/ 3G/4g/5G). This explain the invented details ,features,drawbacks,look of wireless models and comparison and evolution of technology from 1G to 5G and also explaining about wireless application and their services.
Recom Systems Limited consulting services for mobile Service providers. We have unique system where mobile operators or an IT company Generate 50 Million US $ per month.
The project was a study based report on the RAN evolution path of 2.5G EDGE Networks to HSDPA. HSDPA is a 3.5G wireless cellular system, a cost-efficient upgrade to UMTS systems and promises to deliver performance comparable to today’s wireless LAN services, but with the added benefit of mobility and ubiquitous coverage. It can offer data rates of up to 14.4 Mbps which is far beyond what 2.5G and 3G cellular systems could offer. The project focuses on a two-step upgrade, first from GSM towards the deployment of UMTS/WCDMA and then towards HSDPA. It begins a new era of “Mobile broadband” services and faces competition from “WiMAX” – but with GSM services having an obvious upgrade path to WCDMA, HSDPA seems to be leading the market in several parts of the world. HSDPA is an extremely cost-effective path to higher data rates and provides more efficient use of valuable spectrum. It enables operators to compete effectively in increasingly converged markets and satisfy the need for enhanced QoS in an efficient and cost-effective manner.

• The Packet Data Traffic Channels (PDTCHs) use four different channel
coding schemes, described in [GSM 04.60] to transfer the packet data
traffic. Above table lists the used channel coding schemes and the data
rates that can be obtained by using these coding schemes per time slot.
• The maximum data rate that can be obtained on PDTCH channels is
