The common wireless frequency is 2.4 Ghz. Some wireless networks may use the 5 Ghz frequency range.
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.
ELF radio waves or extremely low frequency radio waves. These may have frequencies below 1 Hz in some cases!
Evaluation of wireless networks for performance evaluation is a popular research area and a wealth of literature exists in this area. Wireless networks in infrastructure mode as well as Ad-hoc networks such as MANETs are considered extensively. Simulation results are provided for E-learning scenarios for cases where wireless networks in infrastructure mode are employed, however the possibilities of using adhoc networks and performance evaluation of e-learning scenarios with ad hoc networks are not considered. This paper presents an evaluation of the performances for wireless Ad-hoc networks employed in typical e-learning environment by using the OPNET modeler. Numerical simulation results, discussions and comparisons are provided. The results can be of great help for optimization studies in typical e-learning environments. The performance issues are considered together with scalability concerns.
They are both required, but some cases broadcasting has to be avoided, for instance, in the case when you are trying to establish connection with remote computer to check your bank account.
Possible approaches: (1) based on the MAC address of wireless host (2) user name /password combination. In both cases AP relays information to an authentication server
In most cases the problem is type of security you are using for wireless. If it's the case make sure that your printer is set properly to work with secured networks (it should be compatible too). If you use open type network, the problems usually in setting properties of wireless connection for the printer. Make sure that it configured properly for your type of network: automatically get IP, or manually and so on.
In most cases you can.
Yes, relative frequency probability uses group information and applies it to single cases.
You cannot - except in very trivial cases.
High Speed Wireless Internet can often get you faster speeds than Cable or DSL. You also have the advantage of portability for your laptops, and no messy wires for your desktops. The main benefit from going wireless is freedom to move freely within the network radius. Speeds via wireless routers have gotten strong enough that they are comparable to wired networks, although wired in most cases is still the faster of the two connections. Also, the user is freed from having to link a cable directly to the computer.
Temperature is only sometimes directly proportional to frequency. Temperature however is not always directly proportional to frequency in all cases.
The first thing to start is to restart your router as well your computer. After that make sure that you have a wireless adapter in your computer with the wireless network you have. Also if you are using security, make sure that adapter supports such security option. If nothing works and you know that your router is compatible with your adapter, try resetting the router and start everything over. PS: in most cases people have problems with routers because they are not configured properly or they are not compatible.
