MCBS implemented APNET Project |
APNET
(Andhra Pradesh Network)
Andhra Pradesh (AP) has
always been on the forefront of the IT map of India.
The Govt. of AP has set an example by providing Information
Technology benefits to the grassroots level people of
AP by initiating an Integrated Satellite network called
APNET (Andhra Pradesh Network). This network is an unique
example of integration of various satellite communication
technologies, like television and internet (IP) over
Digital Video Broadcasting(DVB), V-SATs and Ku-Band
receiving terminals. The network will support digital
data and
video broadcast, interactive distance learning, IP based
voice, queries and internet/intranet applications. INSAT-3B
will be used
for this project, and the Indian Space Research Organization
(ISRO) has assured its assistance in setting up such
a complex network.
APNET
Objectives
 To
support distance education for schools, colleges, professional
courses, institutions of

Andhra Pradesh.
Implementation
The APNET project is being implemented
in three phases namely:
I. Pilot : This consists
of 47 nos. of primary terminals (ROT) with 250 nos.
of secondary i.e. one ROT is connected to 5 TV sets
through a cable network. These 5 TV set based terminals
are called secondary terminals. A receive only terminal
comprises a 1.2m solid Ku-Band antenna, LNBF, digital
satellite receivers (MPEG-2/DVB) and 29” colour
TV. This project has been completed successfully in
1999. ISRO provided transmission from MCF Hassan for
this project.
II. APNET (Phase-1)
and APNET Expansion (Phase-2): There are a total
of 161 terminals in five different configurations as
described below, which are a mix of ROT and V-SATs in
Phase-1 project. This has been successfully completed
and is operational presently.
APNET(Phase-2) comprises 1597 terminals which are receive
only types(ROT) and this phase is under implementation.
The Uplink & Hub for APNET project as shown in fig.2
consists of 5 digital video channels & IP channel
using IP over DVB (to broadcast
data & IP) and V-SATs hub equipment for video, voice
and data conferencing. The contract for APNET (1&2)
