Wireless Networking (Wi-Fi) – Advantages and Disadvantages to wireless networking

Advantages of Wifi

• Convenience

  – The wireless  networks would allows users to access information whether be documents-pictures-and music from nearly any convenient location (a home or office). With the increasing saturation of laptop, tablet and smartphone -style computers, this is particularly relevant increasing to user to share with there family, friend and or peers.

• Mobility

  – Public wireless networks  WIFI, Hot spot   users now access to the  internet outside their home, and or work environment. These environment are like   coffee shops, library, in which these establishment offer user  a wireless connection to the internet at little or no cost. called hot spot

• Productivity

  – Users have the flexibility, mobility  connected to a wireless network in which user can  interact their desired network as they move from place to place. Example, business,are able  hire employee for home setting position that can potentially be more productive, cost efficient to business as his or her work can be accomplished from any convenient location.

• Deployment

  – Initial setup of an infrastructure-based wireless network requires little more than a single access point. Wired networks, on the other hand, have the additional cost and complexity of actual physical cables being run to numerous locations (which can even be impossible for hard-to-reach locations within a building).

• 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

  – Wireless networking hardware is at worst a modest increase from wired counterparts. This potentially increased cost is almost always more than outweighed by the savings in cost and labor associated to running physical cables.

Disadvantages of Wifi

• Security

  – To combat this consideration, wireless networks may choose to utilize some of the various encryption technologies available. Some of the more commonly utilized encryption methods, however, are known to have weaknesses that a dedicated adversary can compromise.

• Range

  – The typical range of a common 802.11g network with standard equipment is on the order of tens of meters. While sufficient for a typical home, it will be insufficient in a larger structure. To obtain additional range, repeaters or additional access points will have to be purchased. Costs for these items can add up quickly.

• Reliability

  – Like any radio frequency transmission, wireless networking signals are subject to a wide variety of interference, as well as complex propagation effects that are beyond the control of the network administrator.

• Speed

  –  The speed on most wireless networks (typically 1-54 Mbps) is far slower than even the slowest common wired networks (100Mbps up to several Gbps). However, in specialized environments, the throughput of a wired network might be necessary.
