What are advantages & Disadvantages of wireless Networking in Industries?

Wireless local area networks (LANs) are a testament to their comfort, cost-effectiveness and easy integration with other networks and network elements.

Advantages of wireless networking:

• The wireless nature of such networks enables people to access network funds within their main networking setting from almost any comfortable place. This is especially important with the growing saturation of pcs in the laptop style.

• Productivity: Users connected to a wireless network can maintain a nearly constant affiliation with their desired network as they move from place to place. For a business, this implies that an employee can potentially be more productive as his or her work can be accomplished from any convenient location.

• Initial setup of an infrastructure-based wireless network requires little more than a single access point. On the other side, wired networks have the extra expense and difficulty of actually running physical wires to countless places, which can even be difficult for places within construction that are difficult to reach.

• Expandability: Wireless networks can serve a suddenly-increased number of clients with the existing equipment. In a wired network, additional clients would require additional wiring.

• Cost: The equipment for wireless networking is a small rise from wired counterparts at worst.

Explaining WirelessHART communication

HART is a communication protocol commonly used in industrial communication networks. HART communicate data over the 4-20mA control loop in the form of AC signal in audio-frequency tone. Then HART protocol is introduced into wireless communication mode. The transmitters in the field are connected to wireless network, which communicates with a wireless gate device connected to the controller system. Wireless HART network protocol: Physical layer: Uses 2.4GHz to 2.5GHz frequency transmission …

Disadvantages of Wireless Networking:

• Security: Wireless networks may choose to use some of the different accessible authentication techniques. However, some of the more frequently used techniques of encoding are considered to have faults that can compromise a devoted opponent.

• Range: The typical range of a standard equipment common 802.11 g network is in the order of tens of meters. While it will be adequate for a typical house, for a bigger framework it will be inadequate.

• Reliability: Wireless networking signals, like any radio frequency communication, are subject to a broad range of intrusion as well as complicated diffusion impacts beyond the command of the network administrator.

• Speed: Most wireless networks have a much faster velocity (typically 1-54 Mbps) than even the slowest common wired networks (100Mbps up to several Gbps).
