Spectrum Analysis
• the average 3G spectrum cost/Hz is higher than the average WiMAX spectrum cost/Hz.
• WIMAX spectrum is more economical (because the total 3G spectrum is in lower frequency bands than the total WIMAX spectrum)
• WiMAX base stations can connect to each other even when they are not in the line-of-sight.
Users
• two technologies are close substitutes; both are enabling same types of services for the same devices
and contexts. Differences in the technological performance are also considered to be quite small.
• in case of HSDPA , all users will just have lower data rates, while the load on a WiMAX router in a similar
situation goes up, and it may fail to cope with it.
• Both technologies have practically the same capacities for transmitting multimedia data. Both WiMAX
and HSDPA have QoS and traffic prioritizing.
