19.What are the advantages of a shared spectrum? - ANSWER ✔ Efficiency:
lower priority users are able to use parts of RF spectrum that were
previously allocated to a single user 100% of the time even when they
weren't being used.
Time To Market: It is very quick and easy for new companies to start using
parts of the CBRS RF spectrum, where it used to take over 10 years to gain
possession of bandwidth.
Cost: It is completely free for a new business to begin using bandwidth,
where companies do have the option to pay for higher priority. Before CBRS
it used to cost billions of dollars to take possession of a range of bandwidth.
20.What is an Aggregate Interference Constraint? - ANSWER ✔ Aggregate
Interference Constraint refers to something that makes sure that interference
seen by higher priority users is kept at a usable and acceptable level.
21.Incumbents - ANSWER ✔ Tier 1 users who were using the CBRS band
before the CBRS was created.
, 22.What kind of architecture does CBRS use and what are the individual parts?
- ANSWER ✔ CBRS uses a 3-tiered architecture in order to define who has
priority over others. The tiers are:
Tier 1 - Incumbents
Tier 2 - PAL Users
Tier 3 - GAA Users
23.PPA - ANSWER ✔ PAL Protected Area
24.PAL - ANSWER ✔ Priority Access License

that all information being sent to the SAS is accurate.
27.What are the 4 main incumbents and what frequency do they operate at? -
ANSWER ✔ Military ship-borne radar - 3550 to 3650
Military ground based radar - 3550 to 3700
Fixed satellite service earth stations - 3600 to 3700
Wireless broadband services - 3650 to 3700
28.What does a PAL cover? - ANSWER ✔ a PAL covers a single county with
CBRS transmitting devices in it, over a 10 MHz channel.
