Are you ready for In-Building Fundamentals or Level 1 Certification?
1. What is an example of an interference management technique?
Use directional antennas and sectorization
Increase serving signal
Use ESON algorithms and attenuation
Use omnidirectional antennas
2. Which of the following is true for CDMA systems?
Pilot has to be as high as possible when designing indoor systems
Pilot RSSI should be 5 to 7 dB higher than residual macro pilot RSSI
SHO is not an issue
DL is always the limiting link
3. Which of the following statements is false for coverage considerations?
The number of users can impact coverage and therefore must be taken into account when placing antennas
Antenna placement and orientation have an impact on coverage
Cellular operators often define in-building coverage requirements as a minimum signal strength level within at least a percentile of an area of the building
Macrocell penetration into the building needs to be considered to determine handover boundaries to in-building system
4. Which of the following statements is true?
RSRP should always be lower than -100 dBm
GSM provides data rates of up to 7.2 Mbps
UMTS uses reference signal receive power (RSRP)
SNIR impacts the max. data throughput in HSPA systems
5. When a wave travels from air onto a metallised glass window, the energy in the reflected wave compares with that reflected from a plain glass window as follows:
It is larger
It is smaller
It stays the same
It depends on the depth of metallisation
6. What are some of the advantages of an active antenna system?
Low hardware and maintenance costs
Low noise accumulation with increasing number of elements
Easy zoning and large coverage areas
Local power is not required at remote units
7. Which of the following components is an active component?
Low Loss Cable
8. How many dBm is 20 Watts?
9. Which of the following statements is false for leakage considerations?
In addition to coverage and isolation requirements, signal strength should be maintained at restricted levels to avoid signal spillage outside the building
Macrocell penetration into the building often neutralizes and reduces leakage
Signal spillage is known as leakage, and it is often desired to be kept at a minimum level over a percentile of an area outside the building
Antenna placement and orientation have an impact on the signal spillage outside of the building
10. Which of the following statements is false for capacity considerations?
Blocking happens, when a user attempts to make a phone call without available channels in the cell
Cellular operators aim to maximize the efficiency of their networks in terms of increasing the number of users accommodated per coverage area
When designing for capacity, calculations are performed for regular business hours
The grade of service is a measure of the ability of a user to access a trunked system during the busiest hour
11. Which of the following technologies is typically not supported by Small Cells?
12. Which of the following is not a main Wi-Fi industry body?
Wireless Broadband Alliance
