Wireless networks for personal use are becoming very important tools for human beings, this thanks to its excellent features and benefits that offer each of its users.
Each of wireless networks as is the case of WPAN often use a short-range communication technology , thus allowing the connection of several devices without the need to use any type of cable for connection.
Typically, these connections typically handle speeds of up to 4 Mbps that depend primarily on factors such as light and device proximity. So, here you are We will explain a little more about this type of network, as well as its types and components.

What is a Wireless Personal Area Network and what is it for in computing?
WPAN wireless personal area networks are mainly used to establish communication between different devices such as mobile phones, tablets, laptops within an area of 10 square meters that involve the person or the team in order to ensure proper and correct use.
This type of network has as main objective to allow connectivity between devices without the need to use cables for their connections, as well as to allow a connection directly in short distances.
Among the main features we can find in this type of network are the following:
- They have a approach to home networks that allow devices such as laptops, smartphone, computers, printers to be interconnected, among others.
- They use wireless communication technologies of short range.
- It allows to transmit information bit by bit through a led installed in the equipment that generates a flashing light .
- It is low cost.
- It is usually integrated in mobile devices.
What types of personal networks without wires exist?
There are different types of wireless personal networks that differ from the others by either their speeds, data range, service quality and energy consumption. Usually, there are WPAN that has a high speed range that are used primarily for multimedia applications, other medium speeds used for indoor wireless connections such as Bluetooth, and finally low speed.
Because of this, here are the main types of wireless networks you can find:
Bluetooth
This wireless network technology is primarily used to connect computers to each other, to either share files, photos, videos or any other type of information in such just a few seconds In the case of devices that use this technology, they do not need a direct line of sight to connect to each other.
Currently the bluetooth has been expanding little by little, this is how it is available for hands-free accessories, as headphones . In addition, it is increasingly being used on smartphones and is handled between a radius of 10 and 20 meters between computers.
DECT
Enhanced wireless European digital telecommunications , mostly known as DECT. They are a standard of digital communication used primarily for the creation of wireless smartphones.
This network allows to connect one or more devices to a single network of public telecommunications , for this it uses a large number of stations that provide greater coverage in urban areas .
Zigbee
This technology is used to be able to connect different devices wireless to very low power consumption . This is how it easily integrates small electronic devices such as toys, stereo systems or some appliances.
Zigbee works through a 2.4 GHz frequency band that allows you to reach a transfer rate of up to 250 Kbps > thus having a maximum range of about 100 meters approximately.
Infrared
Infrared networks allow their users to establish communication between two different devices using a series of infrared LEDs. This type of connections allows establish a contact between two devices in a radius of a few meters, with speeds that can reach up to 10 megabits per second.
Infrared technology is mainly used in home appliances that have remote controls, as well as in printers, PDAs, computer connections, cell phones, cameras digital, medical equipment , among others.
Components of a WPAN network What do you need to create one?
The main objective of WPAN is to allow the operation of the different applications in the different technological devices so that they can interact with each other. All this can be done if such equipment is capable of running compatible stack communications.
This indicates that not only the stack communication protocol of each terminal must be compatible , but also the different applications that run on these stacks must be related so that all this can be executed successfully.
Among the components that we can find so that you can create what is a wireless and computer network are the following:
- Transmitter: Create the signal or request from a computer.
- Encoder: It is responsible for encode the signal so that it can be transmitted, it can be a network card.
- Line: In the case of wireless networks the media are frequency waves or infrared.
- Decoder: This means that the device with which you want to share some information or resources also has its own system to convert each of the signals into data which can be processed by the device.
- Receiver: It is the device that has received the signal that has been transmitted from the transmitter converted into actionable data.
