A piconet is an ad hoc network that links a wireless user group of devices using Bluetooth technology protocols. A piconet consists of two or more devices occupying the same physical channel. When a network is established, one device takes the role of the master while all the other devices act as slaves. The master device acts as the hub, meaning the slave devices must communicate through the master device in order to communicate with each other. In most Piconets, the computer serves as the master device.
Piconet gets its name from the word "pico", which means very small. It is so called because the number is limited to seven devices, plus the master, which limits network and data sharing capability. Data transfer rates vary from 200 to 2,100 kbps at the application.
A piconet is sometimes called a personal area network (PAN) because the range of optimal operation for Bluetooth is 10 meters, about the size of a living room.
What Piconets do?
Piconets provide a caching solution that Improves internet speed within a few minutes. This doesn't require upgrading your Internet infrastructure.
The solution acts as a local Content Delivery Network (CDN) and opens caching, HTTP and HTTPS. Piconets also prevent DDOS attacks and make the website faster by automatically converting any HTTP 1.x site to HTTP 2.0. The outcome of introducing Piconets is-
1) Data cost saving
2) Preventing choking of bandwidth
3) Superior QoS to users even if the internet is slow or not available.
Our appliance power consumption is very minimal (1/10th) traditional caching servers. It should be noted that there is an energy consumption/carbon footprint whenever internet is used. Piconets as a solution, hence is a green solution.
A good example of a piconet is the Playstation 3 (PS3) console gaming system. Instead of having wired controllers, the PS3 implements Bluetooth technology to connect up to four controllers at the same time. The main console acts as the master and the controllers act as slaves. Newer home appliances are also able to communicate through Bluetooth.
Some other examples of Piconets include-
1) a cell phone and a computer
2) a laptop and a Bluetooth-enabled digital camera
3) several PDAs that are connected to each other.
