What else can I help you with?
Does infrared technology fall under the category of wireless networks?
Infrared can't be used as a technology for wireless networks because of its slow speed and limited functionality. Infrared is used for wireless communication at very small level.
In most cases the frequencies used by wireless networks are in what frequency band?
The common wireless frequency is 2.4 Ghz. Some wireless networks may use the 5 Ghz frequency range.
Does wireless networks must meet all the same security requirements of a wired LAN?
It's supposed to, but the problem with wireless networks that you can catch packets even if it was not send for you. Such problem was eliminated for wired networks a while ago, the solution is used in all routers. For wireless networks such solution cannot work in principle.
What kind of security measures are commonly used to protect home wireless networks?
To use protected by key wireless networks (WPA, WPA2-PSK AES), MAC filters, deny access to ports which are not used.
What is the highest range and speed standards used for IEEE 802.11n and 802.15?
...the wireless standards used for IEEE 802.11n and 803.15. What is the highest range and speed for these standards?
What is a wireless bridge used for?
A wireless bridge is a hardware unit used to put two or more wireless networks together. They work in pairs, but there may be numerous bridges to get the full effect.
What are the 802.x standards used to specify wireless networks?
Theres a bunch. But the most common are: 802.11a - operates at 5Ghz and transmits data at 54Mbps 802.11b- operates at 2.4Ghz and tranmits data at 11Mpbs 802.11g- operates at 2.4Ghz and transmits at 54Mbps. 802.11n is the newest, it operates at 2.4Ghz but transmits at 140Mbps. These are now availble on MACINTOSH Lights...and they have the new DDR3 RAM also. They are kickin.
How are millimeter waves used in everyday life?
They are used in telecommunications for high-speed wireless broadband communication and point-to-point wireless local area networks (WLANs).
What do wireless sensor networks monitor?
Wireless sensor networks are capable of measuring certain aspects of a physical environment. For example, there are sensors available the measure temperature, pressure, and more.
What device would be used to connect networks using different layer 2 standards?
Bridge
What technology used by wireless networks allows a user to be authenticated by a central authority such as a RADIUS server?
802.1x
Commonalities between 802.11 and 802.16 standards?
Both 802.11 (Wi-Fi) and 802.16 (WiMAX) are wireless communication standards developed by IEEE. They operate in the 2.4 GHz and 5 GHz frequency bands and support Internet access. Both standards provide wireless connectivity over relatively long distances, with Wi-Fi typically used for smaller networks and WiMAX for wider area coverage.
