hey friends this is an interesting question..all of u might be using mobile phones. as well as land phones. but land phones dosent need a battery.. have you ever thought about this??

Hi ,
List all services from google here with  a small description of each services .
I need to find all services from google .com

A blue tooth phone with 10m range cannot communicate with a blue tooth dongle of 100m range if the distance exceeds 10m.Is it true?
Then,what is the use of a blue tooth dongle with high range(100 or above ),when we are setting up a blue tooth hotspot, since communication beyond 10m won't be possible?
Can anyone give a proper explanation on whether this is true or not?
