Broadband Satellite Technology
Broadband wireless
access—LMDS/MMDS (also termed wireless cable)—is
based on the generic wireless technologies for TV distribution (for signals
received from satellite or other sources) in possible direct competition with
cable TV. A standard wireless system simply has a tower and homes scattered
around the tower, and there is nothing between the tower and the home antenna
unless the system is cellularized. Furthermore, it is both flexible and
affordable, and therefore, neither government nor investors have to make
long-term commitments to a particular infrastructure or technology.
Cost Benefit Analysis Especially With Reference To Competing
Technologies
Synergy between telecommunications and TV distribution can
lead to better penetration. In fact, the rollout for telephony would be
considerably cheaper because resources can be shared. This is important because
the cost of external infrastructure for suburban and rural scenarios is
exorbitant and has been an inhibiting factor so far in the growth of
telecommunications.
Advantages And
Disadvantages
The existing cable TV operators find
it profitable to operate in densely populated areas, leaving the sparsely
populated areas to other options. Either direct-to-home (DTH) satellite systems
or LMDS/MMDS systems can fill in this void. The possible regulatory issues to
be addressed are as follows: First, both cable and MMDS/LMDS systems would
provide the regulatory authority to preview/censor un desired
broadcasts/retransmissions as opposed to DTH systems using satellites. At this
stage of development, the opportunity exists to get the option for DTH
foreclosed, as already done by some countries in the Middle East.
Second, for example, the current business rules of the government of
India do not permit the Department of Telecommunications (DOT) to do TV signal
broadcasting. However, the DOT had been providing long-distance links as well
as local end links to Doordarshan. Therefore, the provisioning of the medium
would still fall into the domain of the public telecommunications operators,
and they should lobby for change in the existing regulations. This is important
because there would be stiff competition between cable and public
telecommunications operators for this market if and when the same is opened up.
Third, the most promising frequency band for LMDS is 27.5 to 29.5
GHz, which is presently sparsely used the world over. Of course, satellite
operators are eyeing this band for mobile and fixed satellite services. The FCC
(in the United States) is likely to allocate 1 GHz of bandwidth each to LMDS
and satellite services. The review done in the Test and Experi men ta tion
Center (TEC) on the frequencies beyond 1 GHz also has recommended shared usage.
An early resolution of this issue would be beneficial for long-term growth.
Expected deployment profile
Currently,
there are 4.5 million subscribers in 70 nations all using analogue MMDS
technology. For example, the TV market in India is projected to grow rapidly by
the end of the year 2002 fueled by the following factors:
- TV advertisement to grow fivefold
- Number of TV channels expected in the
range 70 to 85
- Number of TV households to increase by
10.4 percent
- Number of cabled households to increase
by 6.9 percent
- Cable penetration to increase to 59
percent36
In contrast, it is important to note that the projected growth of
demand for telecommunications in India falls far short of the preceding
figures. There is therefore an anomaly in this because a telephone is still an
inexpensive proposition for most households.
Note
The use of telephony in this
area for India is driven in part by the fact that India has the second largest
expatriate population in the world. That is, the number of India natives living
outside India is second only to the number of Chinese living outside China.
The telecommunications market is normally bigger than the market for
TV. In fact, in the United States, the household penetration is 64 percent for
cable TV and 97 percent for telephony. This fact should galvanize the
telecommunications operators into urgent action.
Already a number of operators in
India have signed up for planning, installing, and operating extensive optical
fiber networks for meeting the requirements of cable TV, viz., Hindujas, Siti, and BITV in Bombay, RPG in
Calcutta, and United Breweries Group in Bangalore. The initial objective is to
provide larger numbers of quality TV channels to be followed up by
teleshopping, telebanking, videoconferencing, video-on-demand, and educational
programs. Some of the operators (Globe Satellite Communications) also have
realized the importance of LMDS/MMDS technology, and they have approached the
Ministry of Information and Broadcasting.
