Since its introduction wireless networking has been regarded as a lesser form than that of the tried and tested cable based networks. This reputation, to some extent, has been earned, in that wireless networks were problematic with no real standards, slow speeds and concerns about security.
Wireless networks have become more popular due to the:
- Falling price of wireless equipment
- Creation of standards
- Interoperability of equipment
- Increased security
Although a completely wireless network is possible, it is rare. Most organisations chose the wireless option to supplement and add flexibility to their existing cable networks.
Therefore most modern networks are a hybrid of traditional cable based technology and new wireless options.
