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 […]

What does iPhone have?The iPhone allows conferencing, call holding (the speaker and receiver are shut off without breaking the connection), call merging (a conference call of three members can be created). The iPhone is compatible with other functions, for example a playing song fades out when the user receives a call but the music automatically fades back in when the call is ended.Thanks to cooperation with AT&T Mobility, the iPhone has the Visual Voicemail function allowing users to view a list of voicemail messages without having to call into their voicemails, as well as listening to messages in a non-chronological order by choosing any message from a list.Text messages are presented in chronological order, but unlike most phones, messages are grouped together with replies and displayed in speech bubbles, similar to iChat. There is no traditional inbox and outbox. Text messages are assigned to each contact.CameraThe iPhone has a built-in 2.0 megapixel camera placed at the back. It is not a state-of-the-art device, but with some effort one can take really nice photos. Still, the camera does not support video recording, which is its main drawback.Media playerThe layout differs from previous iPods in various features e.g. the font size. The […]

A basic WiFi home network can be assembled fairly quickly. However, many homeowners aren’t aware of all the options available for making their network better. The wireless network can have its capability, performance and security improved. Consider these tips for improving your wireless home network.
1. Upgrade or replace with correct hardware
In addition to the basic WiFi equipment such as the router and the wireless card, which may be upgraded with newer, faster or more compatible equipment as it comes on the market, other wireless gear such as video cameras, game adaptors and print servers are fun to consider. Do the research and get the best quality equipment for a good price.
2. Install the access point strategically
Assembly of the wireless home network can be done easily0so easily in fact that some people rush into the project only to discover that it won0t work in parts of the residence. Or, perhaps the network works just great until it crashes every time a cordless telephone or microwave is activated. So non-techies are afraid to try to fix the poor performance of the network because they might make it worse. By moving the wireless router or access point to another location, many of […]

Wireless communication is one of the fastest growing technologies. The demand for connecting devices without the use of cables is increasing everywhere. Wireless LANs can be found on college campuses, in office buildings, and in many public areas.

Wifi (wireless fidelity) has brought a new dimension in the field of wireless networking. The transmission of data is done through the radio waves in the free space. It cuts down the cost of laying down the cables for network connections. The systems which are wifi enabled are mobile and can be used anywhere in the range of the network.
Wireless router.
Router is a connecting device, which receives the data from the source and route the data to its destination. Wireless routers refer to the devices in the wireless network, which receives the signal from a source and rout the signal to its destination by examining its SSID. Routers are generally used to interconnect two networks.
A wireless card.
Some systems which do not have in built wifi devices so they need an external interface card which connects the wifi device (a transmitting device) to the system. These cards can be connected to the PCI slot of the mother board.
Also in order to receive the wifi […]
