Question 1 :
What is Airport?
Airport is a wireless communications system, like Bluetooth. It is based on the IEEE 802.11 recommendation. It also uses 2.4 GHz frequency band, but its range is about 45 meters and it boasts a transmission speed of 11 Mbit/second. It is developed by Lucent Technologies.
Question 2 :
Which technology is used in Bluetooth for avoiding interference?
Frequency hopping is the technology used in Bluetooth.
Question 3 :
How many SCO links are there in a piconet?
In a piconet, there can be up to three SCO links of 64,000 bits per second each.
Question 4 :
Which Bluetooth version uses adaptive frequency hopping? Why?
In Version 1.2 Adaptive frequency hopping method is used, which improves resistance to radio interference, and provides higher transmission speed.
Question 5 :
Is it possible to connect multiple Bluetooth hubs?
No, only one hub can be used at a time with a computer. USB or Serial devices can be added.
