A personal network is a collection of devices without a centralized system, often created using mobile devices. It can use Bluetooth, Wi-Fi, or cables and can connect to the internet. Devices connect to a root hub and act as extensions of it. The only limitation is the transmission distance of individual components.
A personal network is a collection of networked devices that do not have a centralized network system. These networks are often created using a mobile computing device such as a cell phone or laptop. The actual method used to connect the devices doesn’t matter, so a personal network is just as likely to use Bluetooth as Wi-Fi or network cables. In the past, it was rare for even a personal network to connect to the Internet, but that has changed as mobile Internet and Wi-Fi have become more common.
A typical network, called a local area network (LAN), is built around a centralized routing system. These central systems, usually routers, connect to each of the devices on the network via wired or wireless connections. When one device in the system talks to another, it does so through the router. The router also determines the priority and order of traffic transferred. Finally, if the LAN connects to the Internet, it does so through the router.
Building a personal network is a little different. Typically, one device acts as the root hub and all connected devices connect to it, although it is possible to daisy chain devices if the hardware supports it. Through this central device, connected devices also connect to each other. From there, they simply act as normal extensions of the core device; the switching and movement priority is governed in the same way in which the central device manages any of its normally installed systems.
The methods used to create a personal network are secondary to network building. As a result, there are many different common methods used to assemble one. In the past, computer wiring was very common, but this has fallen by the wayside with the accessibility of wireless connections. Depending on the devices included in the network, some may use both a wireless and Bluetooth connection.
Outside of its construction, the only real limitation on a personal network is the effective transmission distance of its individual components. Both Bluetooth and Wi-Fi have an effective transmission distance of approximately 30 feet (10 meters). This means that under standard conditions, two of the pieces could be up to 60 feet (20 meters) apart. If your device can accept more connections, you can extend it further.
