Abstract form only given. In the early part of the 1990s, the voice -oriented wireless communication digital mobile technology, also known as the second generation 2G, celebrated its historical success in the telecommunications market and captured the world's imagination from the Internet, gaining over 1000,000 users in 1993. This success soon challenged capabilities and support of internet services and forced the mobile industry to take up a more ambitious plan for supporting the broadband to enable the multimedia communication services under 3GPP. However, growing pressure from the Internet users forced the partnership to rapidly enhance the 2G system to accommodate better data capabilities rather sooner than later with an interim solution, often called 2.5G. At the turn of new millennium wireless technology brought further surprises to the industry, an alternative and equally exciting root from data wireless networking harvested the success of the Ethernet into wireless homes and offices. This unique breakthrough in the market gave 'wireless data networking' a new momentum to aim at capturing a whole new data featured infrastructure riding over the successful 802 style standards. The new capabilities should enable new potential applications and services upon relay based communications, interconnecting a variety of technologies ranged from UWB to WiMAX for broadband access to very small wireless enabled devices over very large areas. This continuous progress and immense development in the key components of wireless technology ignited a further technological race between the voice oriented and data oriented approaches under the NGN and LTE strategic moves to capture the researchers' attention to further the developments and leaving behind all new possibilities for advanced industrial communities to pace useful steps towards new application paradigms and promote a better quality life style. With the rapid growth of potential ad hoc style wireless applications such as medical, geological, industrial and emergency sensor networks we are revolutionizing the usefulness of the wireless and opening a new window of opportunities for the researchers using new tools for ubiquitous access, unstructured networking and resource optimization.
