2. Imagine living without the internet today. Seems almost impossible right?
However Less than 40 years ago this was the reality, there was no Internet.
Nowadays we use the internet for just about everything.
Facebook, Skype, Twitter, Whatsapp; just a few companies that have come from the
internet boom, to name a few.
Companies both nationally and internationally, big or small, all depend on the internet in
order for their businesses to operate. Whether it is for email: ecommerce, cloud based
solutions and so on, the internet has undoubtedly changed the way we do business.
In this presentation I will speak about the different types of Internet Access available
today, and consider the differences between them.
3. Just to make it clear broadband and Ethernet are types of
internet.
• Broadband is a lot cheaper and you have no control over the circuit.
It could drop out at anytime and downloads speeds are always higher
than upload speeds. Contention rates are usually 20/1 or higher.
• With Ethernet the download and upload speeds are a lot faster and
the will run simultaneously. Also if you ever had a problem the network
would know and be able to look into the problem straight away. You have
a lot more control but costs are a lot higher than broadband. Contention
rate is1 to 1! This gives you complete control.
When deciding what would be best for the customer you need to take into
consideration
– budget, bandwidth, reliability, location, type of data traffic.
Ethernet vs. Broadband
4. Standard Speed Connections
o Dial Up
o ADSL
o ADSL2
o Assured Broadband (voice calls only)
High Speed Connections
o Fibre Broadband
o Coverged Broadband
Premium Speed Connections
o Fibre Ethernet
What is Available?
5. Dial Up connections
Dial up is the traditional method of
accessing the internet through a
modem that is connected to telephone
lines.
Dial up is outdated now.
Because dial-up access uses normal
telephone lines, the quality of the connection
is not always good and data rates are limited.
In the past, the maximum data rate with dial-
up access was 56 Kbps
6. ADSL
ADSL is the next generation after dial-up, with
improved speed/performance and more
importantly a split in the line allowing
simultaneous broadband and telephone
connections. It is supplied via traditional copper
wiring. ADSL2 offers faster speeds.
ADSL
Benefits
• Apart from the obvious speed advantages that ADSL
connections offer, ADSL technology eliminates the need for
a second phone line by allowing voice and data transfer at
the same time (you can use the phone as normal while
connected to the Internet).
• Because ADSL transfers data digitally it eliminates the usual
performance overhead associated with standard dial-up
connections. In other words ADSL doesn't need to convert
the data from digital to analogue and back again.
• ADSL connections are Always on which makes the usual
long wait to connect associated with dial-up a thing of the
past
Disadvantages
* A DSL connection works better the closer you are to the
telephone exchange in your location.
* The connection is faster to download (receive data) than to
send information.
* This service is not available in all locations
7. Assured Broadband
What is it?
- Assured IP is a voice only Broadband
connection.
- These Broadband connections are 1:1
contended (uncontended) and prioritise IP
voice traffic above all other traffic.
- They are solely for the purpose of
connecting IP
Telephony systems to our network.
Suitability:
- It’s ideal for small to medium sized businesses and
offers optional capacities of between 5 and 30
concurrent calls. Further benefits include prioritised
voice traffic across the network, UK-based 24/7
support and exacting service level agreements
(SLAs).
8. • Converged Broadband provides high quality internet and IP telephony
access on a single line, from one supplier
• With Converged Broadband you need buy only one service for voice and data
Converged Broadband
Suitability:
• Converged Broadband is
ideal for small businesses
who are looking for a cost
effective way of having two
services for the price of one.
The service supports up to
10 calls at a time
Benefits of Converged Broadband
• A single connection for voice and
data
• Guaranteed voice quality
• 24/7 UK-based support
• Advanced diagnostics tools
10. • Difficult and Expensive to Install
Fibre is costly and disruptive to install, companies often have to dig up
long trenches to put the cable in.
• Equipment and Power Required
The end user has to have some new equipment installed: the NID and
a power source for it. The power source has to continually take
electricity from the user's building or home
Fibre Connections
Disadvantages
Advantages
• Speed and Reliability
The main advantage of fibre is the speed and
reliability in transmitting signals. This means that
users can both upload and download things quickly,
and also have high quality streaming media.
• Long-Term Use
FTTP is expected to be usable as-is for a very long
time.
• Durability
Fibre optic cable is generally more durable than
copper. This means that the network doesn't need to
be serviced as often, which is more convenient for
the ISP and the users.
• Remote Monitoring and Control
The nature of the cables also makes fibre optic
networks easier to monitor than others. Problems
with the network can be identified remotely at the
ISP, with some devices able to detect where a
problem within about 5 feet (1.5 meters). This makes
it easier for technicians to repair any faults quickly.
Business Benefits
Fibre optic broadband is very easy to integrate with other features
and systems. These include:
•VoIP services
•Online Data Backup
•Shared work and collaboration tools
•Cloud-based computing
•Video conferencing
