Like WiMAX, LTE uses radio antenna technologies such as OFDM (Orthogonal Frequency Division Multiplexing) to provide wireless communications solutions. Whereas, in the past, WiMAX and LTE were considered rivals competing for the same market space in 4G communications, the two have recently began to move towards each other in terms of technology and market space.
Long Term Evolution (LTE) is a 4G wireless broadband technology developed by the Third Generation Partnership Project (3GPP), an industry trade group. The 3GPP is a standards body that works within the scope of the ITU to develop 3rd (and future) generation wireless technologies that build upon the base provided by GSM. 3GPP engineers named the technology "Long Term Evolution" because it represents the next step (4G) in a progression from GSM, a 2G standard, to UMTS, the 3G technologies based upon GSM. LTE is not a replacement for UMTS in the way that UMTS was a replacement for GSM, but rather an update to the UMTS technology that will enable it to provide significantly faster data rates for both uploading and downloading.
LTE will provide significantly increased peak data rates, with the potential for 100 Mbps downstream and 30 Mbps upstream, reduced latency, scalable bandwidth capacity, and backwards compatibility with existing GSM and UMTS technology. The upper layers of LTE are based upon TCP/IP, and will support mixed data, voice, video and messaging applications. Like WiMAX, LTE uses radio antenna technologies such as OFDM (Orthogonal Frequency Division Multiplexing) and, in later releases, MIMO (Multiple Input Multiple Output), resulting in a higher signal to noise ratio (SNR) to provide improved coverage and throughput, especially in dense urban areas.
Whereas, in the past, WiMAX and LTE were considered rivals competing for the same market space in 4G communications, the two have recently began to move towards each other in terms of technology and market space. This is largely due to the fact that WiMAX technologies, which deliver the same performance and coverage as LTE is predicted to provide, is an available solution with a progressing ecosystem, which have already been deployed in approximately 500 networks in 146 countries worldwide. Today’s WiMAX is also able to offer a cost-effective, future-proof solution with TD-LTE readiness at hand. This is largely due to the open nature of WiMAX solutions which make it an excellent candidate for migration and answer to the pressing need for reliable, hi-speed wide-coverage wireless networks being conveyed by carriers worldwide.
