Wired Wireless Networking?

Building the Local Area Network, the way ahead
Computer networks for the home and small businesses can be built with wireless or landline. Wired Ethernet, the traditional election in homes, but the Wi-Fi, wireless technologies are rapidly growing. Both wireline and wireless, has advantages over the other, the two viable options to represent the house and other local area networks (LANs).

Here you can compare the wired and wireless networks in five key areas:

•Easy installation
•Total Cost
•Reliability
•Power
•Security

About Wired LAN
Wired Ethernet LAN, using the cable and network adapter.
Although both computers can be directly connected with one Ethernet cable crossover cable, wireline LANs Rule also a power devices such as hubs, switches, routers or multiple computers.

Dial-up Internet connections and hosting your computer you need to use the modem Internet connection sharing or similar software to share the connection with other computers on the local network. Broadband Router facilitate the exchange of cable modem or ADSL-Internet, and they are often also a built-in firewall care.
Installation
Ethernet cable needs from any computer to another computer or to the central unit. It can be expensive and difficult to run cables underground, or by walls, especially when the computers are based in different areas. Some newer homes are already wired with cable CAT5, significantly simplified and reduced cabling I adidas cable is underway.

The correct settings for wiring on a local area network drahtgebundenes varies depending on the composition of the device, type of Internet connection and whether internal or external modems are used. It should, however, not to use these options represent more difficult, for example, the wiring system of a home theater.

As a result of the installation of equipment, the steps in the pattern of local networks wired or wireless, do not differ greatly. Both rely on standard Internet protocol network and operating system configuration options. Portable computers and other portable devices are often more mobility and wireless home network of installation (at least as long as the batteries permitting).
Cost
Ethernet cable, hubs and switches are very cheap. Sharing Connection Some software, like ICS, were released, some priced a little expense. Broadband Router more expensive, but they are optional components of a cable network, and their cost is higher by the performance of the ease of use and built-in security features.
Reliability
Ethernet cable, hubs and switches are highly reliable, in part because producers have increasingly to continue to improve Ethernet technology over several decades. A good number of cables likely remains the most common retail and annoying source of failure in a cable network. During the installation of a local area network or drahtgebundenes Move one of the components of the suite, you should carefully check the connections.

Routers broadband have also suffered some reliability problems in the past. Unlike other speed Ethernet, these products are relatively new, multifunction devices. Broadband Router matured, in recent years, and greatly improved their reliability.
Performance
Wired LAN offer a remarkable performance. Traditional Ethernet offer only 10 Mbps bandwidth, but 100 Mbps Fast Ethernet, the technology is a bit more and can be easily reached. Although 100 Mbit / s provides a theoretical maximum performance never really achieved in practice, Fast Ethernet should be enough for the house, sharing files, games and high-speed Internet access for many years into the future .

Wired LAN Hubs suffer from the use of performance computers slowed down if the network at the same time. Instead, use Ethernet hubs to avoid this problem, a switch costs just over a turnstile.
Security
In the case of a cable network connected to the Internet, are the main firewall security are taken into account. Wired Ethernet hubs and switches do not support firewalls. However, the firewall software like ZoneAlarm products can be installed on the computer itself broadband router offer qualifications firewall, which in the device, software configurable own.
The comparison of wireless LANs with wired technologies
On the subject of wireless LANs
Popularity monitor all wireless technologies one of the top three Wi-Fi communication. The advantages of wireless networking vary depending on the standard used:

•802.11b, the first standard widely used in wireless networks.
•The 802.11a standard is faster but more expensive than 802.11b, 802.11a is more prevalent in business networks.
•The final 802.11g standard, attempts to combine the best of both 802.11a and 802.11b, although it is also the most expensive is not an option for home networking.

Installation
Wi-Fi networks can be configured so that one of two ways:

•"Ad hoc" mode allows you to communicate on mobile devices and networks Peer-To-Peer mode.
•"Infrastructure" mode allows mobile devices to communicate with a central node, which provide communication with the LAN cable node.

Most wireless LANs are in need of infrastructure for the method of accessing the Internet a local printer or other cable services, while the ad hoc mode only supports basic file sharing between mobile devices .

The two uses Wi-Fi, wireless network adapters necessary, and sometimes wireless LAN cards. Infrastructure Mode wireless network requires a complement to the central access point. The access point should be installed in a central location, the wireless radio signals reach with minimal intervention. Although Wi-Fi technology, generally signals up to 100 feet (30 meters) or more, obstacles such as walls can reduce significantly their assortment.
Cost
Gearbox wireless costs a little more than the equivalent wired Ethernet products. In retail prices, wireless adapter and access costs three or four times more than the Ethernet cable adapters and hubs / switches, respectively. 802.11b fell in the prices of essential products for the release 802.11g and, of course, to conclude the sale shall, if they are persistent Shopper.
Reliability
Wireless Local Area Networks are a bit more problematic than the reliability of wireless LANs, even though it may not be enough for great concern. 802.11b and 802.11g wireless signals interfere with other home applicances including microwaves, cordless phones and garage door opening. With care taken in the facility, the likelihood of disturbances can be minimized.

The products of wireless networks, in particular those in the implementation 802.11g, are relatively new. As with any new technology, with whom he still has some time to mature these products.
Performance
Wireless LAN 802.11b supports with maximum theoretical bandwidth of 11 Mbps, roughly the same as that of the old, traditional Ethernet. 802.11a and 802.11g wireless 54 Mbit / s over, that's about half the bandwidth of Fast Ethernet. In addition, the Wi-Fi is far from the performance sensitive, which means that the maximum power of computers deteriorate further from the access point or other termination point communications. Among other wireless devices for greater use of wireless networking, performance even further with the devil.

Overall, the performance of 802.11a and 802.11g is sufficient for domestic use and sharing of Internet file sharing, but as a general rule, is not sufficient for domestic use LAN Gaming.

The greater mobility of wireless LANs will help offset the performance disadvantage. Computer mobile should not be attached to an Ethernet cable, and can freely in the wireless sector. However, many computers at home are more models of desktop and laptop computers are sometimes a cable and electrical outlets for guarantees of power. It undermines the advantage of the mobility of wireless networks in many homes.
Security
In theory, wireless LANs are less secure than wired LANs, wireless, because communication signals through the air and can be easily intercepted. To prove his point of view, some engineers have encouraged the practice of wardriving that travel through a residential area with Wi-Fi equipment to scan the airwaves for wireless networks unprotected. The balance, but the weaknesses of the wireless security are more theoretical than practical. WLANs protect their data by the Wired Equivalent Privacy (WEP) encryption standard that wireless communications as safe as reasonably cable are available in retirement homes.

No network is absolutely safe and owner of this research topic should ensure that they are aware of and comfortable with the risks. Key security considerations for homeowners are generally not linked, if the network wired or wireless, but also to ensure:

•The origin of the Internet, the firewall properly configured
•The family about the dangers of the Internet "e-mails, and how to recognize
•The family is incompatible with the concept of "spyware" and how to avoid it
•Childcare, and other unwanted visitors Haushälterinnen have no access to the network
What is better - wired or wireless?
Conclusion
She studied at the analysis and who are ready to make your choice. In fact, therefore, it is best - wired or wireless? The table below summarizes the main criteria that we have in this article. If you are very conscious of costs, we must optimize the performance of your system at home, not a lot of care and mobility, then drahtgebundenes Ethernet LAN is perhaps the most suitable for you.

If, on the other hand, the cost is less of a problem, as you a fan of advanced technologies, and you are really concerned about the role wiring your home or small business with an Ethernet cable, then you should certainly wireless LAN.

Many of you have, of course, somewhere between these two extremes.
