Long Term Evolution (LTE) is the next step towards in the arena of 3G cellular wireless services. Expected in the 2008 time frame, it is a 3GPP standard which provides an uplink transmission rate of up to 50 Megabits per second (Mbps) and a downlink transmission rate of up to 100 Mbps. LTE evolved from an early 3GPP wireless standard identified as Universal Mobile Telecommunication System (UMTS), which consecutively is evolved from the Global System for Communication (GSM). This paper provides a framework of the LTE physical layer (LTE PHY), LTE architecture, plus its features. Supplementary, it also gives a gestalt of future services including technologies that are new to cellular such as Orthogonal Frequency Division Multiple Access (OFDMA), Single Carrier Frequency Division Multiple Access (SC-FDMA) and Multiple Input Multiple Output (MIMO) data transmission.
