New BlueTooth Interview Questions :: ALLInterview.com http://www.allinterview.com New BlueTooth Interview Questions en-us give the new arrival of bluetooth in wifi http://www.allinterview.com/showanswers/89900.html What is FCC and how does it relate to Bluetooth? http://www.allinterview.com/showanswers/16351.html FCC is federal communication comitee of USA. it is regulatory authority of USA like TRAI(actually DOT) in india. Its role is to allocate frequencies from RF spectrum (1 HZ- 300 GHZ) and providing licences for different application like TV, m Why can Bluetooth equipment integrate easily in TCP or IP network? http://www.allinterview.com/showanswers/15188.html it is an IEEE standard, so interoperability was prescribed at the development phase. How does Bluetooth use frequency hopping for security? http://www.allinterview.com/showanswers/15187.html frequency hopping is a spread spectrum technique in which the transmitter transmits at varying frequencies for very small periods of time say milli or nano sec. these frequencies are choosen in random among the frequency band available. the r What is the frequency range used for Bluetooth in Japan? http://www.allinterview.com/showanswers/15186.html 2472 to 2497 MHz is the frequency range used for Bluetooth in Japan. What is the frequency range used for Bluetooth in Europe and United http://www.allinterview.com/showanswers/15185.html 2402 MHZ- 2470 MHZ in europe and USA Under what frequency range does Bluetooth work? http://www.allinterview.com/showanswers/15184.html it works on the ISM frequency 2.4 Ghz what is the total number of masters and slaves in a piconet? http://www.allinterview.com/showanswers/15183.html In a piconet there can obnly be 1 master and 7 slaves What is a Bluetooth dongle? http://www.allinterview.com/showanswers/15182.html bluetooth dongle is a hardware device. comprising of bluetooth microchip mounted on USB male port. we can connect it to a PC or laptop and transfer data in wireless mode to any other bluetooth device in its periphre. Give a generic description of Bluetooth? http://www.allinterview.com/showanswers/15181.html IEEE 802.15.1 standard, developed by SIG ( special interest group) ericsson, nokia, intel, alcatel. ericsson was the major contributor in the development. named after king of denmark harrald bluetooth for his noble achievements. developed for Which company originally conceived and developed Bluetooth? http://www.allinterview.com/showanswers/15180.html ericcson What is FEC in Bluetooth? http://www.allinterview.com/showanswers/15179.html FEC is the error correcting technique used in bluetooth. it stands for forward error control( or check-- i suppose). in this there is an BER(bit error rate) for a particular transmission which tells about the permissibility of the corrupted b Which technology is used in Bluetooth for avoiding interference? http://www.allinterview.com/showanswers/15178.html FHSS - frequency hopping spread spectrum frequency hopping is a spread spectrum technique in which the transmitter transmits at varying frequencies for very small periods of time say milli or nano sec. these frequencies are choosen in ran How many SCO links are there in a piconet? http://www.allinterview.com/showanswers/15177.html SCO stands for synchronous connection oriented. this type of connection is used for establishing voice channels in bluetooth. there are 3 SCO of 64 Kbps each. other type is ACL, asynchronous connection less used for data. Which Bluetooth version uses adaptive frequency hopping? Why? http://www.allinterview.com/showanswers/15176.html version 1.2 adaptive frequency hopping is used to decrease the effect of interference and make the system more immune to noise, henceby increasing the data rates
