Integration of WIMAX to Broadband Networks Dissertation

Integration of WIMAX to Broadband Networks - Dissertation Example The degradation of transmitted radio signal due to interference from the external source of radio frequency energy diminishes the strength and quality of signal. This makes it difficult for the RF receiver to clearly distinguish the radio signal from background energy. The direct spectrum overlapping due to unidentified internal or external source is the root cause of this problem. The Orthogonal frequency division multiple access (OFDMA) helps to sub channelize and support adaptive modulation allowing the data rates and link quality to be balanced dynamically. This is essential to remove interference as per design layout of IEEE 802-16d (2004) standards. Ensuring proper site survey and round –the-clock access of the structure and the base station helps greatly to reduce the signal interference. Providing closer connectivity points such as towers and access points, and enhancing use of multiple connectivity choices, to make available to user, the best radio frequency, improves Quality of Service (QoS) immensely.  Ã‚  Ã‚  Ã‚   The IEEE 802-16e (2005) standards advocate use of SOFDMA technology that is suitable for using advanced and intelligent antennas to support coverage, facilitate self installation, reduce power consumption, enable frequency re-use, promote power consumption, promote band width efficiency   and provide full mobility support. The WIMAX certification allows complete interoperability with other certified products as long as they fit in same profile.  Ã‚  Ã‚  Ã‚   The hand off system in the WIMAX technology helps to provide continuity.
