Network Infrastructure Basics in the LAB - Assignment Example

Network Infrastructure BasicsLab 6.2.3Summary The requirements in this LAB were that I had to install a wireless network card in the PC in which a built in Ethernet Card was already present. Wireless networking employing the 802.11 standard, also acknowledged by its trade name, Wi-Fi, and has turned into a common home and corporate network system. However, it was ratified in the year 1993. Wireless Card should have the following properties in it.Have transmission speeds up to 54 Mbps.Have transmission distances of up to 150 ft.

Transmit in the 5 GHz range.After reviewing LAB 6.2.2 (Wireless Standard Facts) 802.11a wireless network adaptor amongst the given has all the required functionalities in it that includes frequency of 5.75 (Ghz.), maximum speed of 54 Mbps and range up to 150 Ft. The most important thing about this standard is that there is no backward compatibility it supports. I installed this card in the PCI slot of the motherboard of the PC and completed my LAB.Lab 6.2.4SummaryIn this LAB (6.2.4) requirement was to setup a wireless environment in by installing a high speed wireless card in PC and a wireless access device in LAPTOP which is without a wireless built-in wireless adaptor (Habraken, 2003).

Another thing to check here was to setup a device so that it can be access by any other wireless adaptor. So I used the following devices from the available ones according to the standards given in the LAB 6.2.2 (Wireless Standard Facts). 802.11a/b/g/n access point.802.11n adapter for computer802.11n USB adapter for laptop By using a wireless access point, you have the ability to easily add more computers to the network.Select devices that support the 802.11n standard. 802.11n is the latest standard and supports speeds between 300-600 Mbps depending on the number of transmit and receive radios.

Install an internal PCI wireless network adapter in the computer and a USB wireless adapter in the laptop as it doesn’t have any PCI slot in it.After completing this LAB I have found that 802.11n standard is fastest amongst all the others (802.11a/b/g), with data rate up to 600 Mbps at 2.4 Ghz frequency 802.11n promises significantly higher speed and range. It also includes backward compatibility with 802.11 a/b/g (Labsim). LAB 6.2.5 SummaryIn this LAB (6.2.4) it was required to setup a high speed wireless environment just to transfer files between LAPTOP and computer at very high speed and not to install an extra device.

LAPTOP already has a built-in wireless network adaptor. After reviewing LAB 6.2.2 (Wireless Standard Facts) and amongst the given adaptors I choose 802.11b/g adapter.There were many other devices also available in this LAB including an access point.I installed the 802.11b/g wireless adapter in the computer. As per the Wireless Standards Facts 802.11g operates at 2.4 GHz at speeds up to 54 Mbps.With just the wireless adapter installed, you can create an ad hoc wireless network and connect directly to the laptop to transfer files (Saha, Mukherjee, & Bandyopadhyay, 2003).
