AIM:
Just a decade ago, we were already satisfied on using 56K Dial-up for Internet connection and LANs as a computer network for home, office or small group of building. At that time, we could read news, check email, surf the net, or even sharing files in the office through the local network.
However, because of the growth of technology, it seems we can do more than we expected, and bringing more convenience to us, which is “Wi-Fi”.
CONTENT:
Wi-Fi is used to describe the technology of wireless local area network (WLAN) based on the IEEE 802.11 specification. With Wi-Fi, users enable to use the devices to connect to the Internet wirelessly when the access point is found. Devices can be computer, PDA, mobile phone, etc.
Because of the convenience, now even game players are using Wi-Fi to allow users to play online. Such as Sony PSP, they allow users to go to the Internet, download videos, or connect with other players by just using Wi-Fi.
Advantage of Wi-Fi:
- By comparing with old networking, Wi-Fi allows LANs to connect without cabling, or space constraint, so that Wi-Fi devices can connect anytime even in outdoor.
- It is widely used, so the price of Wi-Fi becomes more economical and cheap.
- It can also support roaming, which can move from 1 access point to the other 1 around the area.
Disadvantage of Wi-Fi:
- Although Wi-Fi can connect the network anywhere, but it has the limited range of connection.
- Too many connection access points in the same area will make confusion.
- Power consumption is higher than some other standards.
CONCLUSION:
In obvious, Wi-Fi is a huge invention for multimedia. It gives users more flexibility and convenience to interact with multimedia or use on multimedia product. Although it has some weaknesses, such as limited range of connection, high power consumption, etc, but it still giving us more opportunities to get to know more on multimedia.
