BGAN

1 The value of BGAN terminals is that unlike other satellite Internet

services which require bulky and heavy satellite dishes to connect, a BGAN terminal is about the size of a laptop and thus can be carried easily


BGAN - Details

1 BGAN users frequently use Performance Enhancing Proxy|PEP

software or other Transmission Control Protocol|TCP packet

accelerators to improve performance.


BGAN - Details

1 BGAN terminals are made by multiple manufacturers. They all have similar

capabilities. The main two that apply to basic BGAN usage are the Standard Background IP (Internet) and Telephone Voice. Data costs from the many ISPs that offer BGAN service averages about per Background Megabyte. Voice calling is on average US$1 per min and varies slightly based on the destination of the

call (Land lines, Cell phones, other Satellite phones which are the most expensive).


BGAN - Details

1 BGAN is currently the fastest global data link available via a portable

terminal. It can be easily set up by anyone, and has excellent voice calling quality. It works on the L

band, avoiding rain fade and other issues of traditional larger satellite

systems.


BGAN - Signal acquisition

1 BGAN is being used in the world today for disaster response,

telemedicine, business continuity, remote site monitoring (telemetry), military use, and recreational use.


BGAN - Terminals

1 One hybrid BGAN technology is the [http://www.groundcontrol.com/The_F

ootball_BGAN_Terminal.htm MCD-4800] aka The Football, which is an

auto-pointing case-based global Wi-Fi hotspot that will run for 6 hours on

internal battery.


BGAN - Coverage and availability

1 The BGAN service is accessible globally, excluding the poles.


BGAN - Standard

1 The Standard BGAN service from Inmarsat provides Internet, phone,

SMS texting, Fax, ISDN and streaming services. It is designed for use with all BGAN terminals except the Hughes 9502 which uses the

BGAN M2M service (below).


BGAN - M2M

1 BGAN M2M service is currently only available to the Hughes 9502 BGAN terminal.


BGAN - Link

1 While BGAN Link service is global, approval by Inmarsat for activation is required.


BGAN - Variants

1 BGAN terminals are allowed to be used on the open ocean on a moving vessel. But because the vessel will

be moving there is great chances to lose the signal and then the

connection. Inmarsat informed DPs that the Core network is not blocking

these connections.


BGAN - Variants

1 Standard BGAN terminals cannot be used on moving aircraft due to

doppler shift effects. An alternative service using more intelligent

terminals to talk to the I4 satellites, named SwiftBroadband, has been

developed for aircraft use.


BGAN - News coverage

1 A media vehicle equipped with an in-motion system does not require

pointing time since the in-motion BGAN terminal is already locked on

satellite.


Bhopal Habibganj railway station - Connectivity

1 The Habibganj Railway Station lies on the main Jhansi - Bhopal Junction|Bhopal - Itarsi Junction (Madhya Pradesh)|Itarsi route line

therefore the trains for all the Major Destinations are easily available. Being

located near to the B.H.E.L Township, Arera Colony, Bhopal Saket Nagar|Saket Nagar and a few other localities, it is always preferred by the people of these areas to catch trains

instead of going to Bhopal Junction|Main Railway Station of Bhopal City.

Sahibganj Loop

1 The 'Sahibganj Loop' is a railway line connecting Khana Junction and Kiul

Junction. Originally a part of the Howrah-Delhi main line, it was

opened to traffic in 1866. With the construction of a shorter railway line for a part of the route, the stretch was assigned a separate identity.


Sahibganj Loop - History

1 With the completion of the long line connecting Raniganj with Kiul in 1871, a shorter main line was in

position. Initially, it was called the chord line. However, as it attracted more traffic it was designated the

main line and the original line became the Sahibganj loop.


Sahibganj Loop - Developments

1 Large portions of the Sahibganj Loop are still having single track. Twenty-one pairs of trains ply on the single

track between Bhagalpur and Sahibganj. Work for doubling the

stretch started in 2010.
