Issue/Challenge
Wireless communication depends
on the availability of and access to
electromagnetic spectrum. But the
growing number of applications that
rely on spectrum—from satellites
to smartphonesexacerbates a
supply-demand imbalance of serious
consequence. Lack of spectrum
access grounds aircraft, delays first
responders, impacts military operations
and training, disconnects consumers
from business and personal cellphone
use, and more.
Looking at spectrum as the backbone
of American life, were developing
innovative, efcient methods to
allocate and manage this limited
national resource. We bring an
objective perspective and national
interest mission to collaboration across
government, industry, and academia
to solve spectrum congestion.
Our goal: enable uninterrupted,
secure spectrum access to meet
critical government uses and public
safety needs, fuel national economic
prosperity and competitiveness, and
support the American public. Among
the many benefits of increased access:
The U.S. cellular industry can innovate
toward 6G and beyond.
MITRE Brings Essential Value | Spectrum Sharing
SHARING A FINITE CRITICAL RESOURCE:
ELECTROMAGNETIC SPECTRUM ACCESS
Shaping radio frequency spectrum allocation and policy solutions to avert
a national spectrum crisis.
MITRE’s Approach
Spectrum today is managed with
bandsor specific frequency ranges
reserved for specific sets of users and
services. Dynamic spectrum sharing,
a technology solution we’ve helped
shape, identifies available frequencies
as demand fluctuates. Think of a city
park where different groups can use
the same space at different times, with
rules in place to prevent conflicts.
U.S. government systems that remain
in their current spectrum allocation can
share the spectrum with commercial
wireless systems. To do this, systems
must be flexible regarding when,
where, and how they use spectrum.
Government systems werent designed
for flexibility, but cellular technology is
designed to manage self-interference.
This capability, paired with AI algorithms
to more quickly mitigate interference,
makes commercial cellular systems
highly adaptable to government
spectrum usage.
资源描述:

无线通信依赖电磁频谱,但频谱供需失衡问题严重。美国正研发创新高效方法来分配和管理这一有限国家资源,以解决频谱拥堵。美国联邦资助研发中心运营商MITRE在频谱管理方面发挥重要作用。 MITRE的方法包括塑造动态频谱共享技术,让不同用户和服务在不同时段共享频段,如美国政府系统可与商业无线系统共享频谱,商业蜂窝系统凭借自身管理自干扰能力及AI算法,能高度适应政府频谱使用。 MITRE的频谱专业知识涵盖多领域,正与美国国家科学基金会等进行实地试验,设计大规模频谱共享实验,目标是确定应对频谱稀缺挑战的可
