3G-WIMAX : Simplifying the Future

Amongst the innumerable potentials 3G has, network manageability is perhaps
the most important one. In the coming years, with increasing Internet usage, a
huge explosion of data will happen over networks. The other major area where 3G
would make a difference is in the billing process.

For infrastructure providers 3G will be a value-add during slowdown, as they
would get to put in a lot of new developments. Layout of next generation
networks that are 3G compatible will help in better manageability of services
over the networks. Even service providers believe that 3G would make the entire
mobility space much more accessible. The government, though, has to look at 3G
with a much broader perspective. The broadband connection, as they have not
reached the set target, will also benefit with 3G coming to India.

Looking at the manageability front, 3G will not only help in managing new
services, but also fall in line with 2G and 2.5G services. It will give a whole
new experience of network management at the back end. “As a 3G network is
downward compatible, SPs would prefer to upgrade their existing networks so that
with increased bandwidth they can offer high-bandwidth applications and services
to their 3G customers, as well as serve more 2G and 2.5G customers on the
improved network,” says Vish Iyer, vice president, service provider, Cisco India
& SAARC.

3G Billing Process

In India there is a larger base for pre-paid customers compared to post-paid
and so there is a greater need to simplify processes for the same. With 3G
services there is a new advent in the next-generation voice, data and content
services. And 3G billing services will give operators the opportunity to handle
and retain the loyalty of pre-paid subscribers.

“Billing systems must cope with the dichotomy in business processes and the
complexity in operations for accurately billing pre- and post-paid subscribers.
This is a challenge that operators must address as it adds additional pressure
to the bottom-line,” says Paresh Shah, vice president, information management,
Convergys India. For post-paid customers it would help the operators to offer
innovative services on demand like real time balance tracking and notifications.
This will actually become the handiest tool to operators as they are working to
limit credit exposure from post-paid subscribers and provide the necessary cross
subscription discounts and invoice generation that subscribers demand.

“In 3G, services priced differently will be posted in one bill. Apart from
that a number of new parameters for calculating charges can be used like number
of packets, uploading and downloading data, QoS, location and content. This will
give rise to complex methods of billing,” says Tamal Bardhan, marketing head,
Usha Comm.

Easier Manageability

Not only on the billing side, but also on the network deployment side 3G is
taking things forward. Solutions and services are getting simpler and handier.
Enterprises and vendors have already started making futuristic deployments for
the new business opportunities that 3G would bring in the network space. 3G's
most important attribute will definitely be better infrastructure management.

“3G will help service providers manage their existing infrastructure better
and remain competitive in a mobile number portability (MNP) regime. It will also
generate a more addressable market to the GSM service providers. They can go
back to their existing customer base and provide them with enhanced data
services” says Animesh Sahay, head, telecom business, India and SAARC, Juniper
Networks.

GSM and VAS are two other areas where 3G would be having a great impact. We
are seeing a growth of around 5 to 6 mn users per month in these areas. The
bandwidth provided right now is nowhere close to what we would have once 3G
services are started. This would essentially lead to easy trafficking of data
over the networks.

3G will not only make its presence felt in cities and towns but also bring in
better and faster networks to rural India. “Looking at the country's broadband
penetration through copper and coax; wireless technologies are becoming
prominent. 3G and WiMax will ensure that remote and rural areas get networked.
Thus 3G is a positive sign of the growth of the Indian telecom industry provided
the government supports it equally,” says Jayesh H Kotak, vice president,
product management, D-Link India.

In the years to come 3G would make a lot of difference in making business
models more innovative. 3G and WiMax will help solve the problem of low
broadband penetration in India to a great extent. It is high time the government
realizes the need and use of 3G. In a fast growing economy these technologies
have the power to change the development roadmap of the country.

Data Matters

The current 2G network limits the download speed to nothing more than 30 to
40 Kbps, though the ISPs claim to provide much more. Even after the use of Edge
technology one gets 384 Kbps of uplink and 171 Kbps of downlink. 3G is expected
to sort out these problems. For enterprises 3G would bring in a lot of
scalability and performance based application cutting short time constraints. 3G
networks will be 2G and 2.5G compatible as well. Consolidation would bring down
the costs for the company.

Apart from the bandwidth, 3G would also enable compressed data over the
network. This would in turn maximize and increase WAN link by reducing the frame
size, thereby allowing more data to be transmitted over the link. Though at this
point we do not need much data compressibility as the transmission will be
through fiber.

3G allows for transferring voice in networks much more efficiently than 2G
and enables efficient VoIP in the future. This leads to decreased cost per bit
and voice minute for the operator, and eventually for consumers. “Today's
networks are many times more efficient than early 3G networks and will evolve to
LTE which is again three times more efficient than current 3G networks,” says
Randep Raina, head, 3G India, Nokia Siemens Networks.

Looking Ahead

Will things stop only with the infrastructure developments of networks in
Delhi? BSNL and MTNL are very differently placed in comparison to other private
players. It is not yet known when 3G auctions will happen and which companies
will be in the spectrum run. With a huge amount of investment only to acquire
license, a lot of other costs would be involved when it comes to network
building and implementation.

But the high costs will lead to new services making its way into the market,
especially the urban areas. “Unlike 2G, in 3G one has to come up with very
innovative applications and tariff plans. If operators are able to come up with
new services there surely is a lot of money to be made,” says Subhendu Mohanty,
country head, home & networks, mobility business, Motorola.

It perhaps goes without saying that vendors are looking at 3G because it is
one of the areas that would bring them enough revenues. For instance, in case of
Motorola their deployments for MTNL in Delhi alone are close to Rs 300 crore.

Undoubtedly, 3G will definitely bring in manageability. With obsolete billing
processes and difficult round ups it is an urgent need for the communications
industry to head towards 3G. For quite some time, 3G has been a vision and a
topic of discussion, but unfortunately, implementation is nowhere in sight.
