Wireless technology is clearly the call of the day with India's
telecommunications industry being dominated by huge growth in the wireless
market. In the aftermath of technologies like 3G and WiMax, the demand will
follow an upward growth.
In the Indian rural landscape, wireless is the obvious choice for operators
and the critical success factors will be to improve coverage while reducing
operational costs. For the rural hinterland, the challenges are big, and
providing wireless connectivity to the customer premises is like winning only
half the battle. At the heart of any well designed wireless deployment is a
reliable, diverse, and robust backhaul network. Optimizing the network with the
antennas-which are usually a de facto component in the wireless kit
infrastructure-will be the focus.
When compared to the global market, India offers a huge opportunity with a
teledensity (both fixed and wireless) and Internet density of less than 50%.
According to research firms IDC and Business Monitor International, the overall
Asia Pacific market is expected to reach 2.2 bn subscribers by 2012 and India,
together with China, will continue to lead the growth.

Market Scenario
In the current scenario, many antenna technologies are catching up in the
market. Antennas which support multi bands, high-gains and variable tilts have
gained support and trust from the market. While tri-band antennas and MIMO
technology based antennas are gaining mileage in the mobile and office segments,
the industry is also witnessing higher performing antennas that have more
control on radiation patterns to improve capacity, and decrease interference.
Multi-band antennas continue to be a hot issue as we see UMTS (3G) services
being overlaid in traditional 2G frequency bands. Through customized filtering
and combining solutions, site sharing of multiple technologies such as HSDPA,
HSUPA, and EV-DO, 1 X, EDGE, WCDMA, iDEN, and GPRS with existing 2G networks is
possible.
For India, the impending issuance of 3G licenses in this quarter means that
operators need to ensure their existing infrastructure on 2G will be able to
co-site and work with new infrastructure for 3G with minimal interference or
even upgrading the existing infrastructure to support 3G.
In addition to 3G, operators are testing technologies such as WiMax and LTE,
and, higher performing antennas to have more control on radiation patterns to
improve capacity and decrease interference.
CIO Concerns

Another interesting development is the concealment solutions as India's urban
areas put more and more focus on aesthetics. This involves hiding the antenna
and associated filter infrastructure to be more aesthetically pleasing.
As such, there is a shift and increase in demand for multi-band antennas for
site sharing and co-siting (a situation in which an operator wishes to locate
equipment on a property, such as a building rooftop, that is already being used
by another operator. But where the property is not wholly controlled, owned or
leased by that other operator) and make sites ready for 3G.
Ruling Trends
The Asia Pacific region consists of highly fragmented markets with both
developing and developed markets at different stages of technology evolution.
There are a lot of opportunities as the needs and requirements of customers at
different stages of technology evolution are varied. Developing markets focus
more on cost, and require simple and cost effective infrastructure solutions
like the 2G rollouts in India.
Analysts and experts say that the market is becoming more sophisticated
because of the tendency of the industry players to focus on more highly
engineered site architecture that could enable them to reap benefits such as
reduced operation costs, improved coverage in rural areas, share multiple
frequency bands, and greater control over their network.
The latest trend remains the customized filtering and combining solutions,
site sharing of multiple technologies with existing 2G networks is possible.
Way to Go
|
New emerging verticals would be shipping and logistics, where wireless would
play an important role. Also, for organizations in the retail segment can use
wireless hand-helds to stock check, inventory check, price check (real time) to
smoothen their front-end and back- end operations. Apart from these two
verticals, rural connectivity (last mile connections) seems to mature up in
terms of transferring triple play traffic.
Keeping the rural hinterland in mind, the main aim is to help customers with
a rapid speed of deployment, and provide capabilities for remote management.
Being able to accurately pinpoint and diagnose network performance issues and
faults within increasingly complex networks, as well as monitor signal strength
and capacity easily, along with a complete tool set to make network construction
and development straightforward, is the only way to enhance the operating
efficiency of a cellular network and ensure all users can connect to the next
generation of services.
Developed markets on the other hand will focus on areas such as network
optimization, 3G, site acquisitions, and green networks. A lot of testing and
initial adoption of WiMax is taking place in India, Taiwan and Japan, as well as
LTE trials and planning across APAC.
With the rise of mobile data services, the need to provide complete access is
crucial and we have been seeing a lot of carriers looking to improve their
in-building solutions and this requires the ability to provide a seamless
end-to-end solution.
Pricing Issue
Antennas are usually considered a de facto component in the wireless kit
infrastructure. Therefore, client expects that the cost of antennas should be
practically 10% or less of the cost of the entire wireless kit. However, usually
it is not the case as there is a considerable cost involved in making antennas.
Therefore, nowadays manufacturers are trying to make in-built antennas with bare
minimal form factor. Additionally, antennas with high gain are also holding
prominence as they are very useful for outdoor connectivity.
Andrew Wireless antennas has an extensive range of 3G antennas, repeaters to
help operators deploy high quality networks quickly. Moreover, customers can
rely on their experience to integrate their 2G/3G feeder systems with diplexers
and combiners which can help to reduce the number of radio antennas on a radio
tower, reducing the weight and load from wind and potential ice, as well as the
necessary size of the tower itself.
Andrew came up with the strategy 'Think global, act local', so as to boost
the local production capabilities by significantly reducing freight and
inventory costs and improving delivery time and availability.
License bands for operators are usually auctioned by DoT at a very high
price. For example, currently there are auctions on licenses for 3G networks
which is an upcoming technology in wireless mobile communications.
Pricing is also crucial with site kitting, for example, different parts of
the RF sub-systems like cables, connectors, base stations, etc, are consolidated
and shipped as a single batch to the actual cell site. In some cases, the parts
are first fitted together and shipped to the site, which reduces the
installation time at the actual site.
Outlook
High growth rates are expected for India, and the impending issuance of 3G
licenses this year means that operators need to ensure that their existing
infrastructure on 2G will be able to co-site and work with new infrastructure
for 3G with minimal interference or even upgrading the existing infrastructure
to support 3G.
From an operator's perspective the deployment of network hardware solutions
that are scalable, future proof and capex efficient will be a critical factor of
success in meeting consumer demands for coverage and performance. Operators need
to ensure that customers can connect to new services in mature markets in order
to increase their ARPU. In emerging and underdeveloped markets, the focus should
be on how to cost effectively add customers to their networks, expand capacity
in urban scenarios and coverage/reach in rural and remote areas, all cases where
emerging technologies such as WiMax may very well play a fundamental role.
By supporting these next generation services, operators can maximize RoI
within the network and leverage it for a competitive advantage. Nevertheless,
they need to better manage increasingly complex networks to respond more
effectively to customer demands, while at the same time become more streamlined
with regard to their capital investment.
For these reasons, operators need to continually optimize their existing
mobile networks. Making the most of available resources is not only common sense
but also backed up by technological arguments. At present, many operators follow
the standard path and address capacity problems by installing additional base
stations at huge expenses-both in terms of outgoings, manhours and high opex.
However, this solution can actually compound the problem. 3G is notoriously
sensitive to interference and too many base stations in close proximity can
disrupt and weaken the very signal they were supposed to strengthen.
By deploying the appropriate network optimization software at a fraction of
the cost of a new base station site, mobile operators can avoid issues of
network overload and dropped calls for their subscribers. The software, which
includes performance management, traffic management and capacity support, allows
network planners to fine tune capacity with the click of a mouse and understand
underlying network infrastructure. It also plays a critical role in asset
management by monitoring individual resources and the levels they are working
at.
Service providers can run real-time environments to explore the most
efficient and cost effective option to enhance coverage and capacity, as well as
monitor core network in real-time to optimize the delivery of service.
Benchmarking tools are increasingly being used to review and enhance subscriber
experience, by allowing specific network problems to be fixed and providing
records of competitive advantage over similar wireless services.
Green and Lean
Certainly, technologies such as LTE will be hot as they will appeal to
operators looking at lowering cost of operations and increasing ARPUs. In
addition, location based services will enable value added services to drive
ARPUs as content can be tailored by location, social networking interaction
enhanced, and information distribution controlled.
However, green IT will have a major impact on the market as well. Andrew
remains committed to environmental protection through research, development, and
manufacturing efforts that help customers implement energy saving and energy
efficient solutions for their networks. For example, understanding the power
requirements for the cell sites and the fact that wireless mobile networks are
large emitters of greenhouse gases based on their need to be powered on.
As such, development of power amplifier technology is highly efficient and in
the case of back-up power for sites, we use fuel cells (hydrogen refill) instead
of batteries (which are not environmentally friendly and are difficult to
recycle).
Impediments to Overcome
|
The additional benefits of hydrogen fuel cells include reliability, reduced
opex for operators, and extended runtime for back-up power. This not only helps
reduce the environmental impact of running a telecommunications network, but it
also has a faster and more reliable turn-on response, reaching full power in
less than a minute compared to three or four times of using diesel generators.
Network operators invest a large proportion of their funds into maintaining
and powering their network. Apart from the cost savings, more and more emphasis
is being placed on corporate social responsibility and its relation to brand
perception. The desire to reduce power consumption within the network no longer
simply comes from the stakeholders. Mounting pressures from consumer groups and
environmental watchers means that operators must look forward and ensure the
solutions they put in place to future-proof their networks are green and lean.
Robust Growth
The market is definitely promising in the years to come. However, one would
see reduction in form factor including internal antennas supporting multiple
bands, multi-technology (CDMA, GSM, Wi-Fi, WiMax) along with smart noise
reduction and interference mitigation capability. Wireless antennas are expected
to grow in the coming times with the demand from operators and enterprises going
up with each passing year.
It seems that at least a 20% annual growth rate would be apt for it to
qualify for on an exponential growth path.
