The demand for broadband mobile services continues to grow. Conventional high-speed broadband solutions are based on wired-access technologies such as digital subscriber line (DSL). This type of solution is difficult to deploy in remote rural
areas, and furthermore it lacks support for terminal mobility.
Mobile Broadband Wireless Access (BWA) offers a flexible and
cost-effective solution to these problems. In recent years the
WiMAX standard has emerged to harmonise the wide variety of
different BWA technologies. The first WiMAX version was based on the IEEE 802.16-2004 standard and offered wireless links to fixed subscribers. The most recent 802.16e standard supports broadband applications to mobile handsets and laptops. This paper analyses the performance of a mobile WiMAX system operating on all link-speeds in an urban microcell. The simulation results are generated using a fully compliant 802.16e
simulator and cover important aspects such as link adaptation, packet error rate and throughput. The theory is supported by
experimental data captured in an urban microcell environment using a mobile WiMAX basestation. Predicted results are
compared with measured data taken from a number of vehicular drive tests. Analysis shows that mobile WiMAX is able to achieve
a street-level range of 300-2100m depending on the permitted EIRP level.
