Question

Task 2
(6 marks) Suppose you want to build a home network that includes a router with an ADSL connection to the Internet, a wireless IEEE802 Wireless LAN, and three wireless IEEE802 Wireless LAN adaptors. Find specific products to suit your needs and price them out.

Answer 1

What is ADSL?

ADSL (Asymmetric Digital Subscriber Line) is a high-speed Internet access service that uses your telephone line to send and receive Internet data at much faster speeds than a conventional dial-up connection. With ADSL you are connected to the Internet 24 hours a day (“Always On”). You no longer need to dial up to open your Internet connection. You can also make and receive telephone calls while online. This is because the ADSL signal operates on a digital frequency, while the voice signals (telephone conversation), operate on an analogue frequency. Voice data and Internet data can, therefore, travel along the line simultaneously. The "asymmetric" in ADSL refers to the fact that the data being received by your computer from the Internet (downstream data / downloading), travels at a faster speed than data travelling from your computer to the Internet (upstream data / uploading).
Complies with IEEE802.11b/g and compatible with IEEE802.11n wireless standards
Provides EZmax wizard to simplify network setup process
Supports point-to-point and point-to-multi point bridge function
Supports WDS mode, Universal Repeater mode and AP client mode
Supports WPA, WPA2 enhanced security function and WPS configuration button
Supports Green WLAN to reduce power consumption by distance and CPU offload when wireless is idle
Wireless 802.11n Range Extender/Access Point
Acting as a bridge between the wired Ethernet and the 2.4GHz IEEE 802.11b/g/n wireless LAN, this wireless LAN Range Extender/Access Point can let your wireless LAN client stations access both the wired and the wireless network nodes.

Universal Repeater Mode
The Universal Repeater Mode lets this Range Extender/Access Point extend the coverage and signal strength for the current wireless environment. This standardized function is compatible with other wireless APs and Routers. Users can use this feature to build up a large wireless network in a huge space like airports, hotels and schools…etc.

Robust Wireless LAN Security (WPA, WPA2 support)
Except for the basic security control by using ESSID and 64/128 bit key length WEP encryption, the EW-7228APn also supports the advanced security features, like MAC access control, IEEE 802.1x authentication, TKIP, AES and hide ESSID. It provides a total solution for you building up a secure wireless LAN network environment that can prevent from all kinds of hacker intrusion.

Multi-languages Setup Wizard
An unique Multi-languages Setup Wizard is provided in the bundled CD. You only need to make sure the access point is properly connected to the network without specifying your PC’s IP address before starting the configuration. The EZmax Wizard will detect your Range Extender/Access Point automatically and guide you to follow a few simple steps to complete the settings within minutes.

Web Configuration
The EW-7228APn allows you to configure this Range Extender/Access Point through the friendly Web user interface with a browser.

Support Green WLAN
The EW‐7228APn has adapted a clever protocol in smart transmission power control. When the wireless is idle, the Range Extender/Access Point smartly adjusts transmission output by distance and CPU offload to reduce power consumption 26%~39% comparing the power consumption under data is transmitted.

the approximate cost is depending upon the using of data speed in asdl.

Wireless-N 300Mbps High Speed USB Adapter-

GW-USMicro300 is the micro small wireless LAN USB adapter, which is compatible with max 300Mbps by IEEE802.11n technology.

You can enjoy 11n 300Mbps communication as well as the Wi-Fi connection between PC and portable game machine, Wi-Fi mobile phone, iPhone / iPod touch just by switching the modes.

Many functions in small wireless LAN adapter-

- Wireless LAN Client - It is compatible with IEEE 802.11n and 300Mbps (theoretical value) is possible. With MIMO technology (Multiple Input Multiple Output) technology, transmission will be done with 2 antennas, so it fasten the networking speed and improve the stability of the data transmission. - - Software Access Point -- With the attached setup soft "Client Manager", the PC with this product can be used as wireless LAN access point. Due to this, your mobile phone, iPhone 3G / iPod touch can do Wi-Fi connection, you can enjoy game with the people all over the world through PSP, Nintendo DS, Wii. With this, your home quickly changes to Wi-FI spot. ?Operation confirmed device? iPhone 3G, iPod touch, Nintendo DS (DS, DS Lite DSi, DSiLL), Wii, PSP, PS3, XBox 360(When the pure wireless adapter is attached)

- Totally support XLink Kai ! -- Software "XLink Kai" is formally supported, which allows you to play the popular PSP/home games via internet. Because it is the PLANEX product, who is the only official XLink Kai Sponsor, you can enjoy battle game and team play with your friends who live far away or the players all over the world. This is XLink Kai formally recommended product.
