A functional dependency describes a relationship between the attributes of an entity such that the value of one attribute is dependent on the value of some other attribute and is very well affected by it.
There can be various sources of information that define functional dependency. For instance, an attribute age can define the functional dependency with the attribute ID. One cannot include the voter ID if they are not above 18 years of age.
Similarly, the attribute date of joining can define the functional dependency with the attribute experience, as the experience in a particular organization can be calculated by subtracting the joining date fro the current date.

Answer:
Bluetooth is a wireless communication is typically limited to six feet distances
Explanation:
Bluetooth is one type of communication maximum it covers 10 meters to 30 meters. but it is one to one communication made for data transactions. After 25 meters of coverage on communication will be very slow on data transactions. But Bluetooth has also had a limitation.
IR. It is one of communication where infrared technology used. It is like face to face communication and speed of data transaction limited and it is also one to one communication made for data transactions. Communication paired and covered very little distances.
NFC it is chip-based and covers very little in fact just to device meet each and communication started. And very it caries very little data during the data transactions. it is also one to one communication made for data transactions
RFID is one of communication and it is powerful to cover more areas with multiple connections at the same time. It has a limitation in distance and it covers like a net with a specific distance
