Indoor

• Size of venue / number of subscribers – iDAS or small cell• Power considerations (POE+, DC, AC), batteries?• Structured cabling considerations – CAT 5/5e/6 or fiber

– Reuse existing or pull new?• Transport – operator or customer provided?

– Is there enough BW and quality?• Aesthetics

– Hidden electronics - antennas above ceiling may require plenum/riser rated equipment, ancillary

Outdoor

• Coverage versus capacity (oDAS versus small cell)• Structures – roof, wall, pole mount (including strand)

– What is the impact of placement?– How do you power?– Zoning requirement

• Site acquisition and zoning (currently, very long lead)– Regulatory – FAA, FCC, City, State, SHPO, NEPA – factors may change

depending on structure location, age• Transport – availability of suitable backhaul

– Wireline, NLOS, LOS, IR

Potential Yield?

Customers, Building Owners, DAS

Providers/Carriers Win

• Increased customer satisfaction

• Higher productivity

• Higher revenues

• Greater cost savings

• Potential to perform more small cell installs


Reliability

• Visibility– Alarms to indicate failures, outages– Performance indicators to detect trends or declining service– Transport monitoring is critical

• AP to EPC layer 3 transport (IP) Signaling and User plane• L2/L3 equipment will often be behind a customer’s firewall

– Rely on automated rules and notifications• Utilize available trace mechanisms to direct resolution• Inform customer of issues based on alarms and alerts

• Serviceability– Ability to repair faults or failures once identified– Worker and public safety – requiring appropriate certifications– Minimal ticket handling, minimal dispatches– Maximum automation, maximum information– Avoid multiple truck rolls

Customer Satisfaction:“The Metrocell is working very well, we’ve seen significant improvements with data connection

and speed which was our biggest issue before installation. Voice also seems to be working well.”

“The individuals within the office have seen a stronger signal and are able to make and receive

calls in areas that they couldn’t before.”

“The new system seems to be working – my primary benchmark is whether or not I experience

dropped calls …. I am not. In the past I received a voice mail notice but the phone never rang to

give me an opportunity to answer it now all calls are coming through.”
