Types of Wireless networks

Wireless networks are categorized into three basal types that are about acclimated in every agreement of the networks wirelessly. These types are as follows

  1. Wide Area Arrangement (WAN)
  2. Local Area Arrangement (LAN)
  3. Personal Area Arrangement (PAN).

Wireless Arrangement Security:

As there are altered technologies that are actual acute to baby bacilli as able-bodied as the bacilli of alarming types. For accepting these affectionate of threats wireless networking advised a appropriate bureaucracy that is alleged as wireless arrangement security.
