Abstract
Mobile WiMAX is claimed to have the greatest potential of all wireless
access technologies already in the markets with respect to network capacity,
range, mobility, and quality of service support. Mobile WiMAX has also adopted
MIMO as an essential element for increasing capacity and data propagation
reliability. However, there are few publicly available studies demonstrating
what is possible with Mobile WiMAX in practice and none that empirically
evaluates the performance gains attained with MIMO. We fill this gap by
comparing space-time coding based 2x2 MIMO with single antenna mode in our
Mobile WiMAX testbed. We conduct thorough measurements that involve vehicular
mobility with different types of traffic. We find that MIMO significantly
increases the reliability of data propagation over the wireless link, which is
particularly evident when we consider TCP traffic. Since 3GPP LTE, the main
rival to Mobile WiMAX, equipment and publicly deployed networks are yet to
become available, HSPA and the soon-to-be-deployed HSPA+ amendments to UMTS
are the only wireless technologies challenging Mobile WiMAX. Thus, we also
compare Mobile WiMAX with HSPA, providing the first publicly available
side-by-side measurement study.
