Wireless dating 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. 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 (the vicinity can be a public and populated space too, like a pub, a street, plaza and so on). If there is a match then they are alerted and can seek each other out and directly chat using text bluetooth (bluechat). Settings can include an option which restricts alerts to subscribers who have a friend in common.
There is an implementation of wireless dating called Serendipity (the gift of finding valuable or agreeable things not sought for) being pioneered by MIT's Media Lab in Cambridge, Mass. (Reported in New Scientist Magazine 20-Mar-2004.). Another open source study called "spontact " will be available at the end of 2004. Spontact comes with ICQ support.
A group of researchers at the Swiss Federal Institute of Technology (ETHZ) have developed a dating application called Bluedating running on mobile phones with Bluetooth. Further implementations include SmallPlanet's CrowdSurfer and MobiLuck . Speck uses its own appliance, but bases exchange of data on bluetooth technology, which might make a port to cellphones possible at one point.

Bluechat is a direct text chat between two or more users, where every one utilizes a bluetooth device (i.e. a modern mobile phone or a PDA) and names it (it will be the user's nickname). The device is generally used in a public and populated space (like a pub, a street, plaza and so on).
To initiate chat one goes to the connectivity menu on one's device and turns on the bluetooth port. Next, one should discover new bluetooth devices (to add one's bluetooth co-chatters). To send the messages, one goes to the organizer program, creates a new note and sends it via Bluetooth to the other device/user.
In any case, the device can be visibly hidden and vibrating alert feature used.
It is common for users to put presentation items (age or age range, sex, sexual orientation, language, and so on) in their nick names or, if too long, in a general profile note. Users can also send contact items, for example email addresses.
In some premises, the admin can create a bluechat-LAN (i.e. in a hotel, hospital and so on), for a wider bluechat network.
Palm OS based devices have a Bluechat application. For Pocket PC OS and Windows Mobile some freeware is available, including ProximityMail Bluetooth devices can talk to any other Bluetooth device with a range of a few meters. This means that complete strangers can communicate with others using Bluetooth devices. The term "Bluejacking" has been coined to refer to people who send irrelevant, surprising, or shocking messages to strangers in their vicinity.
