EMOBILE: the mobile broadband revolutionist - Huawei

Winners
As of September 2008, Reliance had 55 million mobile
subscribers in India or 18% of the market. They provide
coverage for 20,000 towns and 450,000 villages, with
dramatic growth that shows no signs of slackening.
dense urban environs of these megalopolises. The
U Interface Soft Synchronization (UISS) and
interference elimination technologies are used to
reduce interference between networks, allowing
subscribers to enjoy better quality and experiences.
Saving equipment room space
With CDMA sites already being deployed, the
extra space should be utilized for placing the GSM
equipment to reduce TCO.
Reliance uses Huawei’s highly integrated GSM
base station which supports up to 18 GSM carries
by using one cabinet in an area of less than 0.5
square meters. What’s more, extra space is reserved
in the base station for expansion. The footprint is
small and the sound adaptability is so superb that
Reliance is considering sharing its site resources
with other operators to convert its costs into added
revenue.
In big cities like Bombay and Delhi, co-location
of GSM and CDMA sites is largely used by
Reliance to share auxiliary devices like antennas,
feeders, and power supplies. The construction cost
is then far lower than that for conventional separate
network construction.
Decreasing power costs
India has been dealing with a power shortage
for years. As the prices of gas and coal rise, so does
electricity costs and leads to soaring electricity
prices. What’s more, due to equipment aging and
electrical loss during transmission, the transmission
loss rate is up to 50% in New Delhi. Power costs
make up over 60% of the Reliance’s operational
expenditure (OPEX).
It was imperative to lower electricity costs in
thousands of base stations while still providing
excellent service. Reliance searched for the most
efficacious way and found Huawei’s high-efficiency
power amplification (PA) technology. The PA
efficiency keeps ahead in the industry, cutting the
power consumption of the base station by over
60% while providing the same coverage. This is
important in India where electricity is expensive
and the electrical transmission loss is high.
Moreover, Reliance adopted Huawei’s intelligent
power control technology. When traffic is low, a
single or even several carrier modules are used for
subscriber services and other idle resources are shut
down. Alternately, different parts of time slots on
one carrier are shut down to lower transmission
energy consumption. This way the idle energy
usage of base stations is minimized and a high level
of quality of service (QoS) is ensured.
Reducing transmission costs
In India, traffic is much more concentrated
and heavier in some areas with a great number of
calls in one base station or one BSC. In traditional
GSM solutions, this kind of traffic is transmitted
to the core network equipment and then sent
back to the initial base station after switching. In
other words, the traffic data stream starts out local,
travels a long distance and finally returns back. The
process wastes transmission resources on the uplink
