What concerns should be understood about data communications being sent over wireless networks? discuss the pros and cons of one method of transmission, such as wireless application protocol?

Solution:

Mobile and wireless technologies have evolved beyond recognition since the first radio signals were transmitted in the late nineteenth century. The advent of mobile phones and similar devices has transformed business and social interactions, and Internet access no longer depends on a wired system such as a modem connected to a telephone landline - rather, it can be achieved using a mobile enabled device whenever and wherever a mobile access point is available. Such access points or hot spots are now widely available in airports, hotels, educational institutions and other public buildings, and increasing numbers of wireless networks are being installed in commercial buildings and private homes.

Pros and cons of wireless networking are as follows:

Wireless networks or WiFi (as wireless connections are commonly known) have a number of key business advantages over wired networks.

Increased efficiency

Improved data communications lead to faster transfer of information within businesses and between partners and customers. For example, salespeople can remotely check stock levels and prices while on sales calls.

Access and availability

Because wireless technology allows the user to communicate while on the move, you are rarely out of touch - you don't need extra cables or adaptors to access office networks.

Flexibility

Office-based wireless workers can network without sitting at dedicated computers and can continue to do productive work while away from the office. This can lead to new styles of working, such as home working or direct access to corporate data while on customer sites.
