WiFi, which stands for Wireless Fidelity, which is mostly just a marketing term, representing how this technology uses radio signals to transmit data in a computer network. A WiFi network is very convenient, cutting down on the costs of running Ethernet cable through walls in order to have a high-speed network in the home or in the office. However, if you’re new to this technology, you might not know what you need for WiFi in your home. Here’s what will get you enjoying the wireless revolution in your home:
A Wireless Router
The first thing needed for a WiFi network, in most cases, is a wireless router. Many broadband companies now provide this piece of equipment when they set up your service. What the wireless router does is transmit the information that comes from your provider to the other computers in your network. It manages who gets what information and it is the device you configure to determine the SSID, which determines which computers can access your network.
A Wireless Card
However, WiFi with just a transmitter isn’t very useful. Unless your computer or laptop has built-in wireless devices, you will need some sort of wireless card. For PCs, this is usually a card that plugs into the PCI slot on your motherboard and has an antenna to aid in receiving data. If you have a laptop, it’s probably built in, but can also be obtained by a wireless card that you plug into the PC Card slot. Alternately, there are wireless receivers that run through USB as well. With a wireless card to receive what your router sends, you have a basic WiFi network.
The Advantage Of Wifi
The big benefit of WiFi over wireless networks, of course, is that with just a little equipment, you can connect several computers to your home network without running any wires. Even if you don’t have a wireless router at home, for example, as long as you have a wireless card and permission to use an SSID, whether at a coffee shop that offers WiFi access or at a friend’s house, you can have access to a computer network.
Because WiFi equipment is inexpensive, with cards available for under $50 nowadays, it’s also a very affordable technology. If your broadband company provides the router, the startup costs of such a network is very low, giving you access to fast Internet access for research or online gaming anywhere in your home. With such an advantage, it’s easy to see how having basic WiFi equipment can improve your home computing.

In the space of little over five years mobile phones have progressed from gadgets primarily used for voice calls and texting to an appliance that can be used for a myriad of other purposes including; web browsing, sending and receiving emails, GPS, stills and video camera, and also as a music player.
Advancements in WiFi and 3G data network technologies combined with a significant reduction in call, browsing and text costs has been key to the mobile device development phenomenon. Throw into the mix the fact that growing processor capabilities now allow for more in-device storage at a fraction of the 2003 price, and it is easy to see why mobile phones are now becoming indispensible 0do-it-all0 devices.
The launch of the iphone 3G in the UK has drawn much attention, mainly due to the fact that it is available only on the O2 network, but the facilities available on the phone have also renewed the public0s interest in smart phones just as many devices are coming to market.
Indeed, the timing of Apple0s launch couldn0t have been better as most of the major mobile phone manufacturers are also on the verge of launching their own new smart phone products, allowing them […]

A popular technology now being utilised in the asset and package tracking industry if RFID or radio frequency identification. Generally these RFID asset tracking systems fall into two distinct groups, either passive or active. The passive RFID asset tracking systems are widely regarded as the new generation thanks to the technology they utilise, however in recent years further development of the active RFID systems has meant that they now offer a stark alternative to business owners.
Of these active asset tracking systems, they can once again be divided along two major lines. Firstly there are those systems that use their own network in order to achieve tracking of assets or items. The network is predominantly made up from technologies such as readers, antennas and sensors that operate within a facility to track items and assets.
Secondly, it is also an option to install a tracking system that will utilise the existing technologies and infrastructure. This can be seen as the more affordable option as the system will not have to have its own readers and antennas installed in order to track an asset. A perfect way to implement this technology is to utilise the existing WiFi network. For example, in a […]
