Q5. Are existing sites required to be retrofitted to meet new R56 revisions?
ANSWER No. Standards and guidelines are not required to be implemented at
sites built prior to publication of that revision.
Q6. What is the Motorola Site Design and Integration Team (SD&IT)?
ANSWER A team developed to provide consistent and cost-effective design
and construction solutions for public safety and construction projects.
Q7. Name three key areas of expertise of the SD&IT.
ANSWER Site acquisition and leasing, zoning, architectural/engineering
services, construction management, site preparation, tower
foundation/erection, co-location.
,Q8. What is a PERT chart?
ANSWER Program, Evaluation, and Review Technique chart — a flowchart
showing the relationship and sequence of events comprising a project.
Q9. What does QA/QC stand for?
ANSWER Quality Assurance / Quality Control.
Q10. What does PANI stand for in R56 grounding?

Isolated equipment — a method of bonding conductors to the MGB in a
specific order.
Q11. What does MGB stand for?
ANSWER Main Grounding Bar (or Master Ground Bar).
Q12. What is the purpose of the R56 standard?
ANSWER To provide guidelines and requirements for the installation of
communications equipment, infrastructure, and facilities, ensuring safety,
reliability, and proper grounding.
Q13. What is PCS?
ANSWER Personal Communication Services — a digital communications
system providing data services and digitized voice.
Q14. What is a Plat book?
ANSWER A document depicting the legal ownership of specific parcels of land.
Q15. What is a Plenum?
ANSWER A compartment or chamber to which one or more air ducts are

Q26. What is the first step in planning a communications site?
ANSWER Planning and site design drawing preparation.
Q27. List three activities typically performed during site development.
ANSWER Site surveying/staking, constructability review, installing temporary
facilities, clearing land, installing erosion control, excavating access roads.
Q28. Why is planning crucial in site development?
ANSWER Because the activities involved must be effectively organized to
complete the project efficiently.
Q29. What must be considered when locating utility entrances?
