In large-scale wireless systems, the use of this stack results in a network that is unable to respond to volatile spectrum availability which can be typical in unlicensed bands where interference prevails.
In addition, random station/radio availability is also often encountered due to the dynamic traffic load (congestion) and other factors such as radio failure.
Bottlenecks along both wireless links and stations are created because the packet forwarding protocol cannot respond quickly to these changes.
By adopting the cross-layer architecture that merges network routing into wireless link and RF design, the OPM technology can create a dynamic (fluid) wireless network without predetermined topology and spectrum allocation.
The promoters and supporters of OPM claim that the technology may make wireless communications ultimately scalable and affordable; and once it potentially becomes ubiquitous, the commercial impact could be big as comparable to: 1) what packet-switched network technology (Internet) has brought to personal communications; 2) what mobile communication technology (cellular) has brought to telephony.
