Q: What is BroadbandDirect?
A:BroadbandDirect
is a two-way Internet-over satellite solution that delivers fast, reliable and
cost-effective broadband Internet into offices, homes and remote locations.
Using the VSAT technology, it supports web-browsing, e-mail, file transfer,
international VoIP and fax services.
Q: What is a VSAT?
A: A
very small aperture terminal (VSAT) is a device – also known as an earth station
- that is used to receive satellite transmissions. The "very small" component of
the VSAT acronym refers to the size of the VSAT dish antenna that is mounted on
a roof on a wall, or placed on the ground. The key advantage of a VSAT earth
station, versus a typical terrestrial network connection, is that VSATs are not
limited by the reach of buried cable. A VSAT earth station can be placed
anywhere - as long as it has an unobstructed view of the satellite. VSATs are
capable of sending and receiving all sorts of video, data and audio content at
the same high speed regardless of their distance from terrestrial switching
offices and infrastructure.
Q: What makes BroadbandDirect Different from similar ones in the
market?
A: BroadbandDirect has several performance and cost advantages over
competing products in the market. Unlike these other ones, it comes with
high-end stand-alone indoor electronics (not PC Cards) and 1.8m antenna (not 1m
or 1.2m). These features make it possible to upgrade the product to a higher-end
VSAT solution without having to replace the whole installation. Also, monthly
bandwidth cost is within the affordable range (as low as N30,000) and fixed
regardless of level of use. It is not based on amount of data transferred or
“per MB billing”, which is usually unpredictable.
Q: What volume
of Bandwidth is available on BroadbandDirect?
A: Available
bandwidth is in excess of 10Mbps. However there are four bandwidth options for
BroadbandDirect popular users. These are:
-
Option A (upto
64Kbps)
-
Option B (upto
96Kbps)
-
Option C (upto
128Kbps)
-
Option D (upto
256Kbps)
Q: What is the specification
of BroadbandDirect’s equipment?
A: BroadbandDirect
is based on open-standard DVB infrastructure, combined with the rugged and
industry benchmarked Hughes ISBN-hub platform. Apart from the 1.8m dish, the
customer equipment consists of DVB receiver, satellite modem and a RF unit. The
product is powered by world technology leaders, which include Panamsat, Emperion
and Hughes
Q: What is the
difference between VSATs used for data communications and those used for
television reception?
A: The terminals used for TV reception are receive only terminals while
the ones for two way data communication are Receive and Transmit Terminals (Rx/Tx).
The TV terminals require no special license, while for the Rx/Tx terminals the
user is required to be licenced by the regulatory body in their country, in
Uganda, Uganda Communications Commission, in Kenya, Telekom Kenya and in
Tanzania, Tanzania Communications Commission.
Q: What are the
advantages of VSAT links over other types of data links?
A:
-
Immune to distances
between sites to be connected
-
Immune to topological
obstacles (such as tall buildings, hills and mountains)
-
Very fast set up time. A
link between two sites on different continents can be established in a matter
of weeks.
-
Very high reliability
(Typical annual availability = 99.95)
-
Very reliable technology.
-
Create very secure links –
almost immune to unauthorised access and tampering.
Q: What are the
limitations of VSAT Links?
A:
-
Radicated satellite
capacity is substantially expensive
-
The turn round time is
long due to the long distance between satellites and earth locations and this
can affect the operations of some programs.
-
Some VSAT equipment is
relatively expensive.
-
Some types of VSAT links
are affected by heavy rain, and may result in a weaker signal reception
between the ground stations.
Q:What does an
organisation need to have in place to deploy VSAT technology?
A:
-
Economically viable need
for information exchange
-
Software and networks
which are optimised for satellite operation
-
Reliable power source
-
Perform a site survey to
establish suitable location for VSAT terminals.
