WLAN, Wi-Fi, or 802.11 network
What do you mean working with each other? 802.11g is the wireless protocol, which you can secure with WAP or WEP encryption and it would be called a secured wireless network. Also, it would be called a WLAN for wireless local area network. They're the same thing.
If you do not set password for your wireless network you will get unsecured network. If you mean that you want use your router to connect to another unsecured wireless network and create so called "bridge" the answer is yes. But! Router from different manufactures usually do not work together in the bridge configuration. There are some exceptions but just few.
A Cisco network engineer has to plan, impement, verify local an wide area enterprise network. Also work on advanced security, voice and wireless and video soloution.
You can go and buy a wireless network adapter at Wal-Mart wherein they offer you different brands of wireless network adapters. You can also buy such network adapters at www.amazon.com, www.bestbuy.com.
by offering consulting services and solutions for wireless-network operators throughout Asia, Europe, and the United States, and it also provided original content for local wireless-network operators in The Netherlands, Germany, Belgium, France
A Campus Area Network (CAN) is used to connect buidlings across campuses of colleges or Universities. CANs' also connect buildings across a military installation as well. A CAN is actually a type of Local Area Network (LAN). It is larger than a LAN but smaller than a Metropolitan Area Network (MAN). A Home Area Network is the network used in an individual home. Home users may have all of their computers in the house connected toghether by CAT-V (twisted pair) cable or by a wireless network (actually called a WLAN - Wireless Local Area Network).
Wireless tends to be slower than a wired network in most cases, wireless networks are also more inconvenient for desktops if you don't have a built in wireless adapter.
It's called WPA2-PSK AES. You also can use MAC filters.
It's a network architecture which employs wireless devices. Compared to "classical" network topology, where the cable is network medium, in wireless networks is the air a network medium. It means, that all data travels through the air. Wireless topology can be of 2 basic categories: Ad-hoc = no central device, just a bunch of computers connected together through their wireless network adapters. Infrastructure = there is a central device called "access point" to which all client computers connect. This access point provides interconnectivity between clients and also sometimes between the wireless and wired network.
You can purchase a cellular hotspot adapter from your cell provider which will connect to the local 3G network and allow your WiFi iPad to connect wherever you are. The iPad sees it just as a local wireless network.
Through a network. One example of a hardwired connection is called an Ethernet connection. Data can also be transferred through a wireless network by the use of a wireless router.
A heterogeneous wireless sensor network(HWSN) is the network of sensors having wireless link with dissimilar communication range, sensing range or those sensors may be employed in numerous applications. In a distributed HWSN, different parts of HWSN may adapt different network configurations. The answer an be also include energy as basis for defining a network as heterogeneous , If wireless sensor network has 2 kinds of nodes , one type has x times more energy it can be called 2 level heterogeneous WSN and so on .
