Why are spectrum sharing & inter-technology coexistence relevant?
New inter-technology interactions are currently emerging in shared spectrum bands, and they are too complex to be efficiently managed by traditional spectrum sharing mechanisms. These were originally designed for licensed cellular bands accommodating a single wireless technology, or unlicensed bands with low to moderate traffic volumes. By contrast, important current trends are opening bands to multiple technologies and supporting high traffic volumes. It is thus crucial to design novel inter-technology spectrum sharing mechanisms that facilitate an efficient overall use of the spectrum, while fulfilling the requirements of each device/technology.
There are many examples of bands where achieving inter-technology coexistence is currently critical. Some of them are:
- the 5 GHz unlicensed band
- the 3.5 GHz Citizens Broadband Radio Service (CBRS) band in the U.S.
- Licensed Shared Access (LSA) bands in Europe
- mm-wave bands
- the recently opened 6 GHz unlicensed band.
