Technology
3GPP Standards study item since Dec 2004,
Feasibility Study to be completed mid 2006,
Standardization as a Rel’8 or later feature
LTE is a 3GPP initiative to develop a new RAN/air-interface to
– Support high efficiency OFDMA carriers with scalable bandwidths of 1.25-20 MHz
– Provide significantly improved peak and cell edge data throughputs:
– Towards 100 Mb/s Downlink, 50 Mb/s Uplink,
– 2-4 times better spectral efficiency over HSDPA/HSUPA (in bits/s/Hz/cell)
– Support smaller frame durations in order to achieve reduced latencies less than 10 ms
– Support for advanced antenna schemes (e.g. SDMA) and MIMO
– Support for wide range of QoS and Mobility
SAE is a 3GPP initiative to develop a new flat(ter) network architecture (…..2008)
– Simpler system (than UMTS), purely packet-oriented
– Reduced number/type of nodes for lower transport delay….BSR is a major step towards flat IP
– Scalability to support the high data rates required for LTE
Goal of 3GPP LTE/SAE is to Define a New RAN/Air-Interface to Better Deliver Broadband and Real
Time Packet Switched Services over a New Flat(ter) Network Architecture

Summary: Evolution of Wireless Technologies
Initial 3G systems (EDGE, R’99 UMTS, 3G1x) focused on voice, yielding modest
data performance benefits
Evolved 3G or 3G+ systems (HSDPA/E-DCH, 1xEV-DO/DV) provided significant
data performance benefits
HSDPA, 1xEV-DO and 802.16 downlink have similar spectral efficiency
performance
For MIMO systems:
– SM/BLAST offers the best peak data rates,
– SDMA offers the best spectral efficiency.
We see Strong potential of OFDM influencing where WiMAX goes
Time-to-market advantage of 3G will make WiFi / WiMAX complementary
for coverage complement / backhaul applications
the potential of mobile WiMAX hinges on the success of existing 3G technologies
We anticipate Mobile broadband Access will be cellular based

– enabling truely converged services, such as
multimedia/multicast or mobile-TV
Wireless Standards will evolve in parallel
and slowly converge in technology
– 3GPP (UMTS, HSPA+, LTE)
– 3GPP2 (EV-DO Rev.C)
– IEEE (802.16/WiMAX , 802.20)
