Components of wireless LAN architecture
The term architecture is used to define the design of any wired or wireless communication network. In terms of wired networks, it talks about the various hardware used that form part of the network. In a similar way, wireless LAN architecture is also about the components used to form the network itself. Here is a look at the various components that make a complete wireless LAN architecture:
The user
Obviously, this would mean the person who uses the services of the wireless LAN. However, the user in the wireless LAN architecture is more importantly the device used for connectivity. This may include a laptop, a palmtop, a desktop PC or even a video game console. These devices tend to be used for wi-fi access while on the move. In fact, mobility is one of the most important reasons for the success of wireless LAN. These networks can also be used by stationary devices, like desktop PCs in offices or corporate conference rooms. Even laptops that access data in these buildings are usually switched off at the end of the day, which means that mobility is not always the reason why individuals or even businesses prefer wireless LAN.
The network interface card
The next part of wireless LAN architecture is the network interface card or NIC. A wireless interface card or wireless adapter works like the interface between the device and the network itself. It is a part of the device, but it may be internally or externally fitted. The NIC card will work under a certain IEEE standard- 802.11a, b, g or n. The adapter itself is available in many forms, with one being the Peripheral Component Interconnect or the PCI bus. The most popular form of wireless LAN architecture adapters is the PC card found in PDAs and in laptops. The mini PCI card, which is a smaller and lighter version of the PCI card, is integrated in the more modern laptops, and also in other wireless networking devices.
Base stations
The next part of a wireless LAN architecture is the base station, which acts as the interface between the various data signals transmitted through radio waves. One example of a base station is an access point from where devices can access the wi-fi network. As a person continues to move across different access points, the device automatically detects the next powerful access point and moves forward. Other, more complex forms of base stations, is the router, which is typical in a place where data transfer occurs between multiple computers. A base station may support and provide connectivity for either one point to another point or to several points.
The access controller
The next and final part of the wireless LAN architecture is crucial to the security of the network. Access controllers typically form a part of the wired section of a wireless network. It provides control and information on the base stations in a wireless networks. This controller may either be a part of the access point itself, or it may be the central controller.

The Key Rewards Of Wireless Computer Networking
Wireless computer networking has become one of the most common styles in computer engineering industry. The advantages of wireless computer networking over the traditional wired networking have contributed a lot for this switchover. First of all, let's have a look at the rewards of wireless computer networking.
Wiring is the biggest trouble when it comes to netwoking the organizations in the conventional manner. Using RJ45 cables, optical cables and optical fiber cable the entire floor area of the organization require to be wired. For each subsection where there are more than two dozens of computers, it is essential to install a hub or a switch, so the users will get the anticipated networking bandwidth. When it comes to wireless computer networking, this issue does not exist. If you can afford a wireless router or a wireless access point where the signals can hit the entire floor area of the organization, then there will be no wiring involved.
Mobility is the next biggest advantage of wireless computer networking. With the wired computer networks, you had to have a wired connection nearby for you to get at the local area network or the Internet. This limited your mobility even if you had a laptop. With wireless computer networking, your movements are not restricted at all.
There can be more disfavours than the advantages if the wireless computer networking correctly done. First of all, the wireless signal strength does vary depending on the distance between the computer and the wireless access point. Depending on the signal strength, the networking bandwidth will change. Therefore, when it comes to wireless computer networking, giving all the computers adequate signal strength is one of the main challenges.
Let's have a look at the principal necessaries for founding wireless computer networking. First of all, you will require a wireless router or a wireless access point. Although these are a little pricy compared to wired routers, wireless routers have many advantages in the long run. Next, all your computers need to have a wireless networking interfaces installed. Most of the modern laptops come with WLAN cards (Wireless LAN). Therefore, you will have to buy wireless network interfaces for desktop computers. The wireless network interfaces for desktop come in various variants such as PCI cards or USB dongles.
Compared to the conventional networking, wireless computer networking is the simplest to configure and maintain. Since almost all the networking procedures are centralised when it comes to wireless computer networking, network administrators spend less time configuring and troubleshooting network related issues.
Will a 802.11a/b/g Wireless LAN mini PCI card receive a signal without an antenna?
Well, yes but only at a very close range! If this happens to be a high powered card it can be damaged by having no antenna! Just remember to work, they have to transmit too! That is where the issue really gets problematic! The transmitters don't like sending with no antenna - they overheat!
(By short range I mean a few feet! Usually just far enough to let you set it up etc but not far enough to use for much!)
VIA offers $89 processor and motherboard combo for custom HTPCs (Engadget)
If you're looking to craft a small form factor HTPC to an equally small
budget, then VIA's own-brand internals deserve some serious consideration. The
company's 1.4GHz dual-core Nano X2 CPU was recently put to good effect in
Zotac's ZBOX Nano VD01 and is now available as part of a DIY combo called the
VE-900, which puts the processor on a compact mini-ITX motherboard alongside a
VX900 dedicated media accelerator for smooth video handling up to 1080p. The
board has a single PCI slot, room for up to 8GB of DDR3, two SATA pin headers
and four USB 2.0 ports. The rear panel adds to this with HDMI and VGA video
outs, three analog audio jacks, Gigabit LAN, four more USB 2.0 ports and other
standard fare -- but alas, it seems that the $89 price tag won't fetch you
digital audio outs or USB 3.0. You'll find a full PR and promo video after the
break, plus some Nano X2 benchmarks at the More Coverage link.
