Although they share the same hopping sequence, they will usually not be synchronized in time. On trading floors, airports and other environments where multiple organizations may want to operate wireless LANs, DSSS is an inappropriate choice. FHSS allows a large number of nonoverlapping channels. R ANGE LAN2 offers 15. DSSS allows a small number of non-overlapping channels.
Most DSSS products offer one non-overlapping channel, the most sophisticated offers only three.
DSSS inherently consumes more power than FHSS products, requiring heavier batteries or more frequent recharges. Power amplifiers for DSSS transmitters are less efficient than their FHSS counterparts. This causes significantly higher power consumption in the DSSS products. Light weight is critical for mobile applications. FHSS technology allows significantly lighter products to be developed.
