Caselet 1
Recently the FCC has adopted new rules governing “broadband wire line Internet access services” that
remove regulatory obligations on the local telephone companies, while imposing regulation on ISPs. The
results could have a significant effect on the market for broadband information services.
In the Broadband ISP Order, the FCC ruled that, following a one –year transition period, local telephone
companies that provide broadband Internet access over their facilities will no longer be required to
comply with the Computer Rules. As a result, ISPs will no longer have a legal right to purchase
broadband transmission services from the local telephone companies at regulated tariff rates. The
commission asserted that the Computer Rules are no longer necessary because “ a wide variety of
competitive and potentially competitive providers and offerings- such as cable broadband transmission,
satellite, wireless and power line-are emerging.”According to Commission the Computer Rules actually
harmed ISPs by decreasing operators’ incentives to invest in broadband infrastructure. The Commission
also noted that this would result in telephone companies being regulated in the same manner as cable
operators, which generally are not required to provide “open access” to ISPs.
At the same time that the FCC released the wire line carriers from their historic regulatory obligations, the
agency asserted that the Communications Act gives it right to impose on currently unregulated ISPs
regulatory obligations that “mirror” those traditionally imposed on telephone companies.
Because of this ISPs that want to provide a high-speed service rather than purchasing broadband
transmission services from local telephone companies at regulated, tariff rates, will need to either:
negotiate commercial agreements with telephone companies and cable operators; deploy their own
transmission facilities; or be acquired by a facilities-based operator. Negotiating commercial agreements
may be difficult. Several major telcos are already discussing the possibility of charging premium prices to
ISPs that use their network. The end result is likely to be significant consolidation in the US information
services market. This, in turn, could lead to higher prices, reduced innovation and less service
diversification.
At the same time, introduction of new regulation could slow deployment of new services, such as VoIP,
which have generally been treated as unregulated information services. The FCC has already ruled that
“interconnected” VoIP providers must comply with existing rules-previously applied only to telephone
companies-requiring operators to provide emergency operator services and assistance to law enforcement.
Because the FCC has not adopted a definition of what entities constitute “wire line broadband Internet
access providers,” the FCC could seek to apply these regulatory requirements to any service provider that
offers a suite of IT/information services that includes the ability to access the Internet over a broadband
wire line connection.
Question:
1. Comment on the strategy which is adopted by the FCC “broadband wire line Internet access
services” is fruitful or not?

Caselet 2
When operators and investors consider starting down the road of network building, they need
considerable information to prove their business plan and persuade their spectrum regulator to provide
sufficient allotment. This was exactly the situation when a consultancy group approached ATDI on behalf
of their overseas client.
The task was to provide the consultants with a GSM/3G network plan for all the primary cities and link
these to form a national plan for a sizeable country. All of this had to be achieved within 2 weeks. The
network design was for business plan analysis and spectrum application and therefore indicative sites with
indicative topology were required to scope the network. The technology was 2G although the concept
applies equally to 2.5g and 3G.
With traditional, manual methods of approach it would be impossible to meet the task objective set out
above. There are two clear constraining factors- the size of the network and the timescale available.
The approach proposed by ATDI applied technology to the problem. It used IT and software technology
to remove the need for costly man days of effort. And it used complete automation ensuring that the result
was deterministic. In essence the method used highly skilled engineers to set up the modeling tools in
automatic mode and then machine time to complete the work thereby achieving the ultimate in efficiency.
The method proposed to the consultants was ATDI’s network auto-planning methodology.
ATDI used fifteen instances of their ICS Telecom radio-modeling tool to ensure that the tight timescales
were met. Several days were reserved for preparations of the methods to be used and to document what
parameters were used and why.
One of the first steps in auto planning is to define what user population is to be converted. In this piece of
work the following information was known:
•The extent of each city delineated by a vector.
•How many people were in the city defined by a population database?
•How many people the network should support in each year of its life. Traditionally, cell planning tools
express coverage as color overlaid on terrain.
The representation is rather crude compared to what can be achieved-particularly considering that
subscribers can be represented individually or as population groups. This subscriber concept was used
within ICS Telecom to model users in this project. This concept places a subscriber at a point on the
screen that the auto-planned network must cover. Each of these virtual subscribers was used to represent a
real user on the ground.
The method proposed and subsequently used by ATDI to produce the required information was
completely successful. The measure of the success of this methodology was that:
•The 2 week deadline was met.
•2 Engineers were used and hence the cost saving was realized.
•All the required deliverables were supplied. The cost benefit to the consultants was considerable when
compared to traditional network planning approaches. The final cost of the job was a fraction of the cost
of manual methods.
Questions:
1. Explain the concept of ATDI.
2. What are the measures which are behind the success of the ATDI methodology?
