VII. Wireline Broadband (≥ 512 Kbps download)

• The Department of Telecommunications issued a Notification on 18th July,
2013 revising the definition of Broadband as ‘Broadband is a data
connection that is able to support interactive services including Internet
access and has the capability of the minimum download speed of 512 Kbps
to an individual subscriber from the point of presence (PoP) of the service
provider intending to provide broadband service’. Accordingly, the
minimum download speed has been increased from 256 Kbps to 512 Kbps.

• From this month, the service providers have started reporting number of
wireline broadband subscribers in accordance with the revised definition
i.e. >= 512 Kbps.

• As on 31st October, 2013, there are 153 Service Providers (ISPs) which are
providing wireline broadband services in the country. Out of these, 105
SPs (which constitute 98.71% of the market share) have submitted
broadband subscription data for the month of October 2013 as per revised
definition of broadband. For the rest of the ISPs, data from previous month
(with pre-revised definition) has been retained.

• At the end of October 2013, there were 14.91 Million Wireline Broadband
subscribers in the country. However, it may be seent that increase in the
minimum download speed from 256 Kbps to 512 Kbps has not hugely
impacted the overall number of wireline broadband subscribers.

• Top five ISPs in terms of market share (based on subscriber base) are:
BSNL (9.96 million), Bharti Airtel (1.32 million), MTNL (1.11 million),
Hathway Cable (0.37 million) and Beam Telecom (0.34 million).

Annexure IV
VLR Subscribers in the Wireless Segment

Home Location Register (HLR) is a central database that contains details of
each mobile phone subscriber that is authorized to use the GSM core network.
The HLRs store details of every SIM card issued by the mobile phone operator.
Each SIM has a unique identifier called an International Mobile Subscriber
Identity (IMSI), which is the primary key to each HLR record. The HLR data is
stored for as long as a subscriber remains with the mobile phone operator.
HLR also manages the mobility of subscribers by means of updating their
position in administrative areas. It sends the subscriber data to a Visitor
Location Register (VLR).

Subscriber numbers reported by the service providers is the difference
between the numbers of IMSI registered in service provider’s Home Location
Register(HLR) and sum of other figures as given below:-

1 Total IMSI's in HLR (A)
2 Less: (B=a + b + c + d + e)
a. Test/Service Cards
b. Employees
c.

Visitor Location Register (VLR) is a temporary database of the subscribers
who have roamed into the particular area, which it serves. Each base station
in the network is served by exactly one VLR; hence a subscriber cannot be
present in more than one VLR at a time.

If subscriber is in active stage i.e. he is able to send/receive calls/SMSs he is
available both in HLR and VLR. However, it may be possible that the
subscriber is registered in HLR but not in VLR due to the reason that he is
either switched-off or moved out of coverage area, not reachable etc. In such
circumstances he will be available in HLR but not in VLR. This causes
difference between subscriber number reported by the service providers and
numbers available in VLR.

The VLR data calculated here is on the basis of active subscribers in VLR on
the date of Peak VLR of the particular month for which the data is being
collected. This data is to be taken from the switches having the purge time of
not more than 72 hours.
