hat is PAN Network?Advantages and Disadvantages of PAN network.

What is PAN Network?

PAN network stand for personal area network.In this network all the personal devices are connects to form network.Its range is 10 meters to 33 meters.All devices should be in this range to form network.This is not different form what is WAN network?But devices,node,range make it different form WAN,LAN,MAN network.
Some personal device are,laptop computer,mobile phone,cellphone,PDAs,printer etc.It is also called WPAN (wireless personal network).It is always uses to communicate all personal device with each other.But some it is use to connects with higher level network.But they need gateway to connect.
A personal area network are wireless or wire interfaces.

Technologies Use to Build a PAN:

This network can be wireless or form by cables.Mostly U.S.B and Fire-wire are link together to form PAN network.
While WPANs use Bluetooth or infrared connections.

Diagram of PAN Network


Bluetooth WPAN:
Bluetooth is uses for short-range radio waves.Uses in a WPAN include,such as pointing devices, keyboards,audio and video head-sets,printers, cell phones and computers. A Bluetooth WPAN is also known as piconet. This is compose of eight(8) active devices and these devices are connects with master slave device.In this network first piconet will be master slave relationship.
The range of piconet 33ft or 10 meters,but range can be increase up-to 330 ft or 100ft. Long range Bluetooth routers have large range up-to 1000ft. We can also use this network in mesh network.In this way you can send data from one place to another.There is no need of master slave device in this network.
Infrared Data Association (IrDA):
In Infrared Data Association we use infrared light.Infrared is generally uses in remote controls.Many other devices use IrDA such as printers,keyboards etc.The reach limit of a WPAN varies from centimeters to few meters.IEEE 802.15 has produce standards for PANs operating system.

Wireless Personal Area Network (WPAN):

This is a type of PAN carry over a low-power.This network is short distance wireless network.
Some examples of PAN are:
  • Wireless keyboards
  • Wireless Mice
  • Smartphones
  • TV remotes
  • Wireless printers
  • Gaming consoles
  • Bluetooth
  • Fire-wire
  • ZigBee
  • Ultrawideband
  • Wibree
  • wireless USB

A PAN Network:


  • What is WAN network?
  • What is MAN network?

Advantages of personal area network:

As PANs are for personal use, so benefits are more easily understandable than LAN,WAN,MAN.
  • In PAN no extra space requires.
  • No need of extra cable and wire.
  • Easy connect to many devices at a time.
  • Affordable Cost.
  • PAN is easy to use.
  • It is very reliable.
  • This network  is fully Secure.
  • We can use in office meetings.
  • It is use in TV remotes, AC remotes etc.
  • Data can Synchronize between different devices.
  • Portable

Disadvantages of personal area network:

  • Its range is less.
  • Its interfere is with radio signals.
  • Transfer of data is slow.
  • It create Health problem.
  • Cost is high in terms of communication devices.
  • Infrared signals travel only in a straight line

difference between computer science and computer information systems

  Computer Scientist Salary ‍ Fresh computer science graduates may expect the minimum salary of $39,000 per annum. This, again, depends on their skill set. Continued education and certification is always an option in the field and it always leads to career advancements. Certification programs are available through professional organizations, software companies, and product and service vendors. There is a lot of room for growth with the median computer scientist salary being $76,205 per annum. The ideal option for both professions would be adopting a freelance or consultant position.  Freelance engineers  will easily find remote jobs. The gig-economy is booming and businesses are currently urgently in search of engineers. computer science and software engineering     Software engineers may expect high salaries. This depends on their skill set and specialization, as well as on the actual position. Senior positions usually call for a doctoral degree or continued education. According to th

telecommunications network engineer

    A network controller, also known as a  network control operator  or a network control technician, is a tech specialist who monitors the overall engineering infrastructure of an organization. The individual plans, designs, and evaluates to ensure that network performance is not compromised. The main responsibility of a network control operator is to maintain the network by tracking the performance of the network as well as managing issues through routine troubleshooting. They restore to service any of the components comprising the DRSN or DISN networks, including multiplexers, data terminal equipment, data/voice communications equipment, and transmission media. If the problems lie within a complex network, controllers resort to high-level troubleshooting. They work closely with an engineering team to provide network architecture design and recommend new technologies to improve existing performance. A network controller’s overall responsibilities include participating in the day-to-d

architect job description

  When they join an organization,   Security Architects   understand their systems thoroughly. Following that, they research, plan, and devise resilient security mechanisms. They carry out risk assessments, test for vulnerabilities, perform security evaluations, research security systems and standards and authentication protocols. Architects state requirements for routers, LANs (local area networks), WANs (wide area networks), firewalls, VPNs (virtual private networks), and other susceptible network devices. Moreover, they need to strategize public key infrastructures (PKIs), including the use of digital signatures and certification authorities (CAs). Architects examine and certify installations of servers, routers, VPNs, and firewall, among others. They inspect final security mechanisms to confirm that they are functioning as they should. Architects also need to monitor and guide the security team, and outline, implement and take ownership of an organization’s security policies and pr
