LTE physical laye
Long Term Evolution (LTE) is the next step forward in cellular 3G services. Expected in the 2008 time frame, LTE is a
3GPP standard that provides for an uplink speed of up to 50 megabits per second (Mbps) and a downlink speed of up
to 100 Mbps. LTE will bring many technical benefits to cellular networks. Bandwidth will be scalable from 1.25 MHz to 20
MHz. This will suit the needs of different network operators that have different bandwidth allocations, and also allow
operators to provide different services based on spectrum. LTE is also expected to improve spectral efficiency in 3G
networks, allowing carriers to provide more data and voice services over a given bandwidth.
This technical white paper provides an overview of the LTE physical layer (PHY), including technologies that are new to
cellular such as Orthogonal Frequency Division Multiplexing (OFDM) and Multiple Input Multiple Output (MIMO) data
