Currently there are very few actual implementations of scatternets due to limitations of Bluetooth and the MAC address protocol.
However, there is a growing body of research being conducted with the goal of developing algorithms to efficiently form scatternets.
When their mobile phone comes in the vicinity of that of another subscriber (a radius of about 10 meters) the phones exchange details of the two people.
If there is a match, then both users are alerted and can seek each other out and directly chat using Bluetooth (bluechat).
However, when a piconet is formed between two or more devices, one device takes the role of the 'master', and all other devices assume a 'slave' role for synchronization reasons.
Piconets have a 7 member address space (3 bits, with zero reserved for broadcast), which limits the maximum size of a piconet to 8 devices, i.e. A scatternet is a number of interconnected piconets that supports communication between more than 8 devices.
Using this approach, it is possible to join together numerous piconets into a large scatternet, and to expand the physical size of the network beyond Bluetooth's limited range.
Wireless dating, Widating or Bluedating (from Bluetooth) is a form of dating which makes use of mobile phone and Bluetooth technologies.
Subscribers to the service enter details about themselves and about their ideal partner, as they would for other on-line dating services.
Scatternets can be formed when a member of one piconet (either the master or one of the slaves) elects to participate as a slave in a second, separate piconet.
The device participating in both piconets can relay data between members of both ad hoc networks.
