Fundamentals Of Wireless Routers
The majority of households today contain some sort of DSL or broadband Internet connection. To ease the use of the Internet service, wireless connections allow the user to roam anywhere with their hardware system without the use of connected wires or cables. If you haven’t made the move to Wi-Fi connectivity, here are the basics.
In short, standards have been set by the Institute of Electrical and Electronics Engineers (IEEE) dictate the current frequencies and data rates of transmission. The latest two standards are 802.11g and 802.11n. 802.11g has the speed capability of 54Mbps at a frequency of 2.4Ghz. 802.11n has the ability to move data at a higher rate of 150Mbps to 300Mbps. These facts are important for a few reasons. One, your actual transmission speed depends on the distance of transmission, line of sight objects standing between you and the transmission point, the wireless router you are using, and other issues of interference that could affect your rates.
When shopping for a wireless router, the current technology you desire is an 802.11n system. The top systems on the consumer market are manufactured by Belkin, D-Link, Cisco owned Linksys, Netgear, 3Com and a few others. Items in a top of the line wireless router should include a modem port, USB ports, Ethernet ports, and hopefully a firewall. And speed, the most important factor when you are cruising the Internet.
One overlooked factor in Wi-Fi use is security. The majority of public Wi-Fi is unsecured. Which brings undesired probing and spying from those around you. Anyone can share your system and discover personal information, including banking, passwords, email, and more. At the very least, security in the form of WPA2 (Wi-Fi Protected Access) should be used, even in the home. This is a method of algorithm security that will provide protection. Using a Virtual Private Network (VPN) as a go-between when connecting to the Internet is also advisable.
Professionals who are in the networking field and desire to increase their potential, their salaries, and the direction of their careers should enter into a certification course, such as a CCNA Wireless, CCNA Voice, or CCNA Security. Cisco also has a CCNP certification course for those seeking the professional level of training and certification.
Certification from the area of information security achieved through CISSP online training places you in high demand, as data security is a growing field with no end in sight. A skilled, certified professional trained from sources including K Alliance receives global recognition, a career complete with many, many opportunities, and a community of like minded professionals concerned about protecting information in its many forms and locations.
