Posted by on November 29, 2010 No comments

Today, it is quite difficult to imagine what a ‘disconnected’ world will be like. Without the Internet, there will be no social networking sites, no veritable source of information, no instant messaging service or e-mail!

Thanks to modern technology, the Internet has made the world virtually smaller and the means of communication and gathering of information has become more advanced and instantaneous.

Aside from improving the way that people communicate, the Internet has also made it possible for people to work away from the office. Telecommute jobs and work-at-home opportunities have become widespread – which is one of the reasons why having a broadband Internet connection at home is essential.

Broadband Internet in the United Kingdom

When broadband connection was still rare and expensive, very few people can afford to have a speedy Internet access right at the comfort of their own homes. The way that people used to connect to the Internet back then was using a dial-up modem – which does not have much to offer in terms of speed.

Over the years, however, the demand for a high-speed Internet access has increased, which also broadband Internet a much more common in the UK.

Before delving deeper into the different types of broadband connection which is available for you – here is a quick definition of the high-speed Internet-related terms:

1. Broadband: refers to a high-speed Internet connection, usually with a 512-Kbps speed – which is about 10 times faster than a typical dial-up connection.

2. ADSL: refers to Asymmetric Digital Subscriber Line which is available in majority of the areas in the UK. If you have ADSL broadband, the connection will go through your existing telephone line through a router or a special modem. The good thing about ADSL is that there is no need for you to have a separate telephone line installed. Also, you will be able to use your phone even if you are connected to the Internet.

Aside from these two, your other options for Internet connection are cable, satellite and wireless.

Why are Different Broadband Internet Connections Available in Different Areas in the UK?

Once you decide that you do want broadband, the type of connection that you can have is not really dependent on your personal preferences. Instead, you have to take your pick from what is available in your area.

This is because not all types of broadband Internet will be available where you live. For example, if you live somewhere remote and ADSL is not available, you may need to settle for satellite, cable or wireless connections for your Internet access.

This is the reason why your telephone exchange information and your postcode are needed if you will be using the availability checker of Internet Service Providers. They would first need to check on the type of connection which will suit you the best, depending on your location.

Once you have determined which types of broadband Internet connections are available in your area – you can take your pick from there and choose one which will best suit your Internet connection needs.

Choosing the Right Type of GPS

Posted by on November 24, 2010 No comments

In order to make the right choice from all of the various GPS systems available in today’s market, it is necessary to have a practical understanding of what they offer, and what the user can  expect from the device.

There are four major components that need to be looked at.

1.  GPS receiver (or antenna).   GPS receivers use signals from satellites which orbit the Earth at known positions. Each satellite has its own identification code and sends a signal which the GPS receiver can use to calculate the distance from the device to that satellite.

2.  The portion of the system which uses the received information to estimate where the device is located on an internal map.

3.  The various capabilities for route planning and recording, which vary from unit to unit.

4.  Finally, the display portion (which can vary considerably from limited location information to full color three dimensional maps of the immediate surroundings and advised route).
Since all GPS systems are based on the same premise, it is a good idea to at least be aware of the underlying technology so that you can make an informed decision when choosing which system is best suited for you.

Much like regular triangulation, by using 3 to 4+ signals, the device finds the point in space at which the spheres representing the distance from each satellite intersect.  This allows the device software to estimate its own position by finding that point.
Using this location information, the software can then pinpoint the devices location on a map, then use the information for a number of operations, from simply displaying the location, to mapping a proposed route.

The three standard classes of GPS system are road, hiking and maritime.  Each class is further subdivided into other types which offer different features depending on the users intended use and the environment within which they will be operating.
It is important to remember is that this technology does not allow for the transmission of actual mapping data via the satellites. It is purely concerned with identifying the location of the device.

Once you have identified your exact needs and expectations regarding your device, you are ready to assess your options and make a selection.
