Wireless Network The Seventh Meeting

Wireless Standard

3 WiFi  There are two modes, namely WiFi Ad-hoc and Infrastructure.  Currently there are three variations of which is often used, namely: a, b, and g

4

5 WiFi-Ad Hoc Mode  Ad-hoc mode is basically similar to a bus topology on the wired network. Ad hoc mode does not require a central node or Access Point.  Wi-Fi client can communicate in a peer to peer. Each Wi-Fi client will act as a liaison and repeater (signal amplifier) for the Wi-Fi client who is in the next

6 WiFi-Ad Hoc Mode  Ad-hoc mode is suitable if the WLAN to be built will not connect to the wired line.  This mode is usually built in emergency conditions such as sudden meeting in a place that is not available wireless networks

7 WiFi-Ad Hoc Mode

8 WiFi-Infrastruktur Mode  Infrastructure mode is similar to a star topology on the wired network line.  Infrastructure mode / point-to-multipoint use at least a central node or access point.  Access point serves as a liaison with WLAN and the wired LAN.  The access point can also be used as a repeater for all Wi-Fi clients.  The entire network will be totally disconnected if the access point is used dead or damaged.

9 WiFi-Infrastruktur Mode

Wireless LAN  Wireless LAN acting as an extension of a wired network with high flexibility  To expand the network without cable installation, can be easily used to provide a connection without a building / campus that has a large area Perluasan Akses Dengan Multi AP Koneksi antar LAN dengan wireless

Wireless PAN  Wireless is used in a relatively short distance <30 feet, is used to transfer information at a limited distance  WPAN not require a lot of battery power so it is ideal for small devices such as audio headsets, PDAs, game consoles stick, digital camera etc.  Technology: IrDA, Bluetooth, Ultra Wide Band

13 Bluetooth (802.15)  Bluetooth is a wireless communication technology (without cable) which operates in the frequency band of 2.4 GHz unlicensed ISM (Industrial, Scientific and Medical) by using a frequency hopping transceiver capable of providing voice and data communication services in real-time between hosts bluetooth with a limited distance range of services.  Bluetooth can be a card that form and function is similar to the card used for wireless local area network (WLAN) that use radio frequency standard IEEE

15 WiMAX (802.16)  Access to the data communication using the WLAN standard IEEE , and is commonly called WiFi. But WiFi has limited range area, a simple QoS, frequency of use can be licensed or unlicensed, and capacity is limited. Because of limited mobility that is supported by the demands of users, the WiMAX technology developed by using standard IEEE a

18 Cellular  Cellular network component consists of a base station, MTSO (Mobile Telecommunication Switching Office) and mobile communication devices.  The function of the base station is providing the connectivity of radio communication with mobile devices that are in a region of the cell.  While serving as a regulator of traffic MTSO communication receiving and connecting a call from a mobile device users to the PSTN network, monitor the quality of the communication signal and regulate the flow of the base station which handles the communication with a mobile device.

Wireless Wide Area Network  Wireless Wide Area Network uses mobile telecommunication technology / cellular network to transfer data such as: WIMAX (applied to the WMAN Networks), UMTS, GPRS, CDMA2000, GSM, CDPD, Mobitex, HSDPA or 3G  Allows the connection of a laptop with internet access using WWAN card, , VPN access, etc. via cellular phone.
