- What is the difference between WCDMA and LTE?WCDMA was specified in the 3GPP release 99 and 4 of the specification, while LTE was specified in the 3GPP release 8 and 9. Unlike WCDMA, LTE supports variable bandwidth from 1.25MHz to 20MHz. When the data rates are compared, LTE provides massive downlink and uplink speeds than WCDMA. Also, the spectral efficiency is much higher in LTE than that of the WCDMA. LTE provides much simpler and flat network architecture than that of the WCDMA. CS core network part of WCDMA, which includes MGW and MSC Server is completely replaced by PS core in LTE using the SAE-GW and MME. Also, the PS core nodes of WCDMA that consists of GGSN and SGSN are replaced by the same SAE-GW and MME respectively. RNC and Node-B nodes in WCDMA architecture are completely replaced by more flat architecture with only eNode-B in LTE. New interface between eNode-B’s are introduced in LTE, which is not available under WCDMA. LTE is more optimized for IP packet based services; there is no circuit switch core with the WCDMA. LTE provides more flexibility than that of WCDMA when comes to network topology and scalability. In general, WCDMA is considered as 3G technology while LTE is considered as 4G technology.LTE provides higher data rates than WCDMA by achieving higher spectral efficiency. Also, LTE technology provide more flat architecture that is mainly focused on IP packet based services than that of the WCDMA. LTE topology is much more flexible and scalable than of the WCDMA due to the flat nature of architecture.

- Today’s state-of-the-art EDGE networks typically offer user speeds of 200kbps, with end-to-end round-trip time (latency) of 150ms.Features like advanced link quality control and persistent scheduling have improved performance significantly over standard GPRS and the first implementations of EDGE. For example, the time it takes to download a web page is about one-quarter of that taken with standard GPRS. Network efficiency also impacts end-user performance. Compared with basic implementations, the latest EDGE systems have greatly improved resource utilization, multiplexing capabilities for several users and other capabilities that maximize network efficiency.
- The QoS and policy control in LTE are much richer and flexible.LTE is much better optimized for short packet transmission.What is the difference between WCDMA and LTE?WCDMA was specified in the 3GPP release 99 and 4 of the specification, while LTE was specified in the 3GPP release 8 and 9.
