This document provides an overview of global trends in mobile data usage and LTE technology. It discusses how mobile data is overtaking fixed broadband growth. It also summarizes that LTE aims to provide improved mobile broadband through increased spectral efficiency and simplified network design. Key LTE technologies include OFDMA for downlinks and SC-FDMA for uplinks, as well as support for flexible bandwidths up to 20 MHz. The document compares LTE to 3G technologies and outlines the evolving 3GPP system architecture. Potential LTE applications and current deployment status globally are also summarized.

2. Global Trends

3. In 2009 Analyst Predicted that Mobile Data will Overtake
Growth of Fixed Broadband by 2010

Choice of either 3GPP-based or IEEE-
based technologies available today to
support increasing mobile data
growth while waiting for LTE & 4G !
At the end of Q3 2010, Globe’s Broadband Subscriber breached the 1 Mn
mark of these about 70 % are wireless-based.

4.  Demand for higher data rates and quality of
service
 Additional spectrum and greater flexibility in
frequency allocations, but spectrum is a
scare resource
 Keeping up with other emerging technologies
 Low network complexity
 Continued demand for cost reductions
(CAPEX & OPEX)
Growing experience with the take-up of 3G is helping to clarify the likely
requirements of users, operators and service providers in the longer
term.
Increasing Mobile Data Usage is Driving the Need for More
Spectrum Efficient Technologies such as LTE

5. With 3GPP’s HSPA+ Evolution, Globe’s existing 3G Spectrum Can Allow it to scale
up to 21 Mbps and then to 42 Mbps DL (with 3GPP Rel. 8)

LTE is a totally different ballgame ! New Spectrum, new
architecture, and new CPE’s.

11. LTE Key Technologies
• Downlink based on Orthogonal Frequency Division Multiple Access or OFDMA
– Improved spectral efficiency, capacity etc
– QPSK, 16QAM and 64QAM modulation schemes supported
– Downlink target (bits/sec/Hz/site) – 3 to 4 times than HSDPA
• Uplink based on Single Carrier – Frequency Division Multiple Access or SC-
FDMA
– Similar to OFDMA but is better suited for uplink from hand-held devices (battery power
considerations)
– BPSK, QPSK, 8PSK and 16QAM modulation schemes supported
– Uplink target (bits/sec/Hz/site) – 2-3 times than HSUPA
• Spectrum flexibility
– LTE to operate in 1.4, 3, 5, 10 and 20 MHz bandwidths
• Significantly reduced latency
– Radio access network latency less than 5 ms in unloaded conditions for small IP
packet(user plane)
• All IP-based architecture
