History of Mobile Devices
Mobile phones have become a crucial part of our daily life nowadays. Everyone – from teenagers to old men – has a personal cell phone of their own. But the mobile phones we see now didn’t look like this earlier, instead they were something totally different, something you wouldn’t even think of having around you or using.
Improved technology has made a great change in the history of mobile phones, transforming the huge brick-like mobile phones of 1995 to sleek and stylish smartphones we carry with us now.
How Cellular Networks Operate
Mobile phones and their base stations transmit and receive signals using electromagnetic waves (also referred to as electromagnetic fields, or radio waves). Electromagnetic waves are emitted by many natural and man-made sources and play a very important part in our lives.
A mobile phone sends and receives information (voice messages, fax, computer data, etc) by radio communication. Radio frequency signals are transmitted from the phone to the nearest base station and incoming signals (carrying the speech from the person to whom the phone user is listening) are sent from the base station to the phone at a slightly different frequency. Base stations link mobile phones to the rest of the mobile and fixed phone network. Once the signal reaches a base station it can be transmitted to the main telephone network, either by telephone cables or by higher frequency radio links between an antenna (e.g. dish) at the base station and another at a terminal connected to the main telephone network.
Current Hardware, Software and Apps
There is a constant array of new hardware and software goods on the market for consumers to purchase. Big brands such as Apple and Microsoft are constantly bringing out new editions of their signature goods such as the iPod with Apple and Microsoft’s Xbox and laptops.
Apple has just released their new line of their world famous Macbooks: The new Macbook Air. To correspond with the release of the last Harry Potter film, the Deathly Hallows Part II, a game for most game platforms has been released following the plot of the film. The game is available for Xbox 360, Playstation 3, Nintendo DS, Wii and Windows PC, meaning you can play it regardless of which games console you own. Apple have also recently released their iPad 2, following on from the iPad but with many new features and design alterations. The new iPad is 33 percent thinner than the older one, also boasting the fact that it is 15 percent lighter too.
Impact on Society
2013: the year which holds technology’s future. 2013 holds so much potential for the future that we can’t even fathom the idea of what’s coming, positives and negatives.
Looking at the current generations (particularly 25 and under), and the upcoming generations we can see so clearly that society is not going to stop moving away from this idea of using technology as our primary communication methods. This is not to say that technology is ruining society because that’s so far from true; however, it is dumbing our society down. We’re removing the necessity of skills such as face-to-face communications, Technology has made learning, making friends, having fun, and interacting so much easier than ever before. It would be a shame to use the capabilities of them and turn them into our worst enemy.
