What encoding or modulation technology does 802.11 use?
FHSS- Which has been dropped recently DSSS- which is still used by access points to advertise themselves
What is fhss?
FHSS continuously changes the center frequency of a conventional carrier several times per second according to a pseudo-random set of channels, while chirp spread spectrum changes the carrier frequency. Because a fixed frequency is not used, illegal monitoring of spread spectrum signals is extremely difficult, if not downright impossible depending on the particular method. FHSS is the transmission technology in Bluetooth. See http://www.answers.com/topic/802-11-technology, http://www.answers.com/topic/wi-fi-technology and http://www.answers.com/topic/bluetooth-technology.

What is the signaling method used by Bluetooth?
FHSS(Frequency Hopping Spread Spectrum)
What and how is technology used for microphones?
the micro phone use the communication is developed .
Spread spectrum techniques fhss and dsss?
"Direct Sequence Spread Spectrum (DSSS)DSSS multiplies the data bits by a very fast pseudo-random bit pattern (PN sequence) that "spreads" the data into a large coded stream that takes the full bandwidth of the channel. DSSS is the basis for CDMA cellphones and 802.11 Wi-Fi wireless transmission. For a technical example of DSSS technology, see cdma.Frequency Hopping Spread Spectrum (FHSS)FHSS continuously changes the center frequency of a conventional carrier several times per second according to a pseudo-random set of channels, while chirp spread spectrum changes the carrier frequency.

What is alternative technology and holistic technologies?
Alternative technology is a term used to refer to technologies that are more environmentally friendly and holistic technology is a concept concerned with treatment of entire systems.
Can new technology solve world problems?
There is no way of knowing if new technology will solve world problems since we have no way of knowing what new technology is going to be developed, or for that matter, what world problems will exist at the time that technology is developed. It is possible that new technology will be used to solve world problems, and it is also possible that new technology will be used to make world problems worse. We will have to wait and see.
What is meant by military technology?
technology that is developed meant to be used for military purpose only. example the gps navigation devices were at one point only used by the military.
How was LIDAR technology discovered?
LIDAR technology was developed in the 1960's. It combined the laser and radar technology to calculate distance. It was first used in meteorology to measure clouds.
What technology did the Romans develop?
The Romans developed or improved upon various forms of technology. By using their "gromma" they surveyed and layed out their roads. They developed concrete and used it in different weights in their domes (the pantheon is a prime example). They also perfected the arch in buildings and bridges. They developed the syphon and grading system that they used in their aqueducts and they developed central heating.
When was wireless technology developed?
The first wireless technology was developed well over 200 years ago. The first radio which is considered wireless was used in 1895 and sent a message across the English Channel.
What is Concept of process?
A concept of process is a kind of technology that is used mainly in some software applications. It is an artificial intelligence engine that provides adjustable user interface.
