CONTINUOUS INNOVATION BASED ON CUSTOMER NEEDS
Customer Demands
nergy conservation and emission reductions have become an imperative
social responsibility for operators. In the meantime, they hope to cut
operating expenditure, maintain competitiveness and create a winning
ecosystem by addressing global environmental concerns.
Huawei Innovations
With a series of innovative green solutions, Huawei is a true pioneer in this
era of environmental awareness.
Green Base Station
Huawei’s next generation green base station solution adopts best-in-class
power amplication technology, increasing amplication efciency by 45%
and effectively reducing power consumption. The distributed architecture
enables the amplier to be mounted on a tower to reduce feeder loss.
Consequently, power consumption can be reduced by over 20% without
any loss of coverage. The drop in power consumption makes it possible
to utilize air ventilation and green power supply, resulting in less use of air
conditioners and minimal noise pollution.
Green Core Network
Huawei provides a unied 2G/3G core network, enabling optimal sharing
of existing equipment. The efcient MSC pool conguration solution
promotes network efciency and cuts energy consumption by 20%. The all-
IP solution reduces the cost of transport resources and also reduces power
consumption. Combined with low power consumption components and
heat emulation technology, power demand per user is expected to drop
by 10% in 2008.
Green Broadband Network
Huawei green broadband network can help operators save 30% of energy
in three years: the multi-chassis cluster router cuts power consumption by
60%; the hardware compatibility of optical transport series products helps
effectively protect initial investment; the industry-rst no-fan design for
FTTx realizes a 20% energy saving.
Green Equipment Room
The modular design of Huawei’s green equipment room greatly simplies
transportation and installation. This facility is especially relevant for locations
where transporting equipment has previously been hampered by difcult
terrain such as urban high rise apartment buildings and mountainous areas.
It only takes four people one day to install a green site. Augmenting the
environmental benets, meticulous equipment layout minimizes the overall
footprint and an optimal temperature control method can be adopted to
balance with the outside environment. With Huawei’s green base station,
land and electricity use can be dramatically reduced.
