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.

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 […]

Most of us have seen some of the amazing technology which we are supposedly going to be using in the future (as well as the ideas seen in sci-fi films!). But today we are living through the wifi age; however, some of us seem to have got a little left behind. When it was topical it was not available to the average user, and suddenly we are playing technology catch-up. So here is a guide to get you up to date.
Wifi stands for wireless fidelity. This is a technology which allows users to access a network through the transmission and receiving of radio waves. Nearly all laptops and notebooks are now fitted with WiFi technology. If you are considering using an older laptop you can get adapters which will make wifi possible. Bear in mind that as more and more laptops are wifi compatible, the manufacturers will slowly phase out the adapters, so think forward and decide if that really is the sensible way forward.
If you are looking to use your laptop when you are out and about you will need to find some hotspots. These are usually in cafes, airports, hotels […]
