Understanding the Different Types of Wireless Routers

Wireless routers are a type of internet router that functions both as a router and wireless access point. Many companies are using wireless routers to gain access to internet. We have listed a few key factors for you to understand the different type of wireless routers:

Standards

The first thing to look for in a wireless router is the wireless communication standards 802.11b, 802.1g and 802.11n. These are simply referred by the letters ‘b’, ‘g’ and ‘n’. First generation of wireless routers are ‘b’, followed by ‘g’ and ‘n’; with ‘n’ being the latest one. The primary difference among these routers is in their speeds and ranges.

Single Band versus Dual Band

Wireless communications operate in two bands of 2.4GHz and 5GHz. Routers that operate only in the band of 2.4GHz are called single band while wireless n routers that can operate in both bands are routers of dual band.

2.4GHz band is a frequency also used by other wireless devices as well therefore there is much interference and crowding resulting in lower speed and consistency. On the other hand, due to less interference, 5GHz delivers better performance and coverage than 2.4GHz.

Speed   

                                                                                       

The speed of wireless routers differs with different standards affecting the performance of your internet connection too. The speed of wireless routers increases with the development of technology so 802.11b provides the lowest speed, while 802.1g provides greater speed followed by 802.11n providing the greatest speed of 300Mbps.

Wired Connectivity

The wireless routers make use of Ethernet ports for better transmission rates as the transmission speed of wired Ethernet port are greater than wireless connections.

Single WAN or Dual WAN

Most wireless routers provide a single WAN port for internet connection. If that port fails, one will immediately lose all connection. This could prove dangerous in business, for your employees can lose access to other employees.

A wireless router with dual WAN ports ensures connectivity by providing a second link to the internet in the case first one fails. Therefore it’s a smart choice to opt for a dual WAN to ensure smooth connectivity to the internet.

Tips to Succeed via Cisco Certification

Whether you are looking to advance your career or considering a career change, earning a Cisco certification is, indubitably, worthy of boosting your IT career. However, you require careful planning and training to maximize the level of success in your Cisco career. Following are some guidelines for mapping out your Cisco certification strategy or should rather say tips to achieve success in IT career via Cisco certification. Have a look!

·      Set goals – This is an essential step in becoming a Cisco professional. As Cisco specializations are large in number, it’s best that you map out what you’d like to accomplish for the year and try to stick to that plan as much as possible. Lack of planning is one of the largest reasons behind exam failure. Students simply move into study without an actionable plan. Make sure you have the time to put in the necessary work.

·       Use a combination of study materials – Most of the times, it has been seen that a student does not do well because he or she did not use the proper study material. The large number of books available can be overwhelming to those just starting out, but keep in mind your study is not limited to books alone. Get involved in the Cisco community and use a combination of websites, forums and books to maximize success.

·     Get trained – Training is a key ingredient to success. There are several schools which offer training in a boot camp-style setting, through a live online portal and/or self-paced online programs. These schools offer several advantages as their classes are often taught by well-regarded industry professionals. They typically use real routers and switches and can give students individualized attention in a small classroom setting.

·     Practice – They say practice makes perfect and it’s no different for a Cisco engineer and it has been found that a mix of 40% reading and 60% of your time practicing lab scenarios is a good combination to prepare for Cisco certifications. Get familiar with commands. Your best bet would be to get real live devices and set up a lab at your home. While this can be expensive, you can get used equipment online at a much cheaper price.

·     Don’t Neglect The Basics – This is essential for anyone planning to be a good Cisco engineer. There are certain core concepts that every engineer must know. Never neglect the basics such as Subnetting. Subnetting is a CCNA concept that engineers deal with in their careers every day. If you do not master subnetting earlier, you will not only be unable to do your job, but you will have to go back and re-learn the concepts you’ve already studied.
