11 November 2010
Global Trends
In 2009 Analyst Predicted that Mobile Data will Overtake
Growth of Fixed Broadband by 2010
Source : Informa Oct 2009Choice 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.
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
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.

• LTE or 3G Long Term Evolution is the next
step in the evolution of 3GPP radio interfaces
to deliver “Global Mobile Broadband”
– standardization based on improved use of the
radio spectrum
– Standardization based on simplified system
design

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
