Broadband Wireless Communications

 

In the recent years, with the introduction of the capability to access the Internet through cell phones, demand for wireless broadband access has grown at an overwhelming rate. Recent reports indicate trends are changing in communications as social networking becomes more popular everyday, generating significant traffic, and streaming video becomes increasingly important, constituting the largest portion of data traffic. These new trends increase the ever-growing demand for broadband even further. The traffic from cellular handsets are estimated to increase almost twice by 2014.

 

Emerging wireless broadband technologies aim to meet these increasing demands. The next generation of mobile telecommunication networks -4G, or Long Term Evolution (LTE)- introduces increased capabilities along with the promise of an All IP Network (AIPN). In 2009, European Commission announced it will invest a total of € 18 million into researching the deployment of LTE and the certified 4G system LTE Advanced.

 

 

Next generation broadband introduces many research areas. One of the main problems to address is interoperability. With different kinds of services and technologies handling handoff across these technologies is a new challenge. Energy consumption is another important issue. With increased capabilities and additional services, the new wireless handsets will need novel mechanisms to lower energy consumption. LTE devices also support short range communications to support peer-to-peer (P2P) high-speed wireless links between mobile stations. Therefore, one of the more important areas is to explore ad hoc networking for the LTE devices. These ad hoc access mechanisms can be used to reduce energy consumption as well to combat adverse effects of channel variations and shadowing by choosing nodes less susceptible to such effects as relays.
