Models of hardware boards on base stations

Site location

A site survey is an inspection of an area where work is proposed, to gather information for a design or an estimate to complete the initial tasks required for an outdoor activity. A site survey can cover various aspects, such as antenna installation space, equipment room space and load bearing capacity, site location, and other environmental factors. However, a site survey does not cover the models of hardware boards on base stations, as this information is not related to the physical characteristics of the site. The models of hardware boards on base stations are determined by the network design and configuration, which are based on the network requirements and specifications.

QUESTION 42
Which of the following statements about the advantages of the Rayce ray tracing model are correct?(Select All that Apply)

It offers more accurate modeling for massive MIMO.

It offers more accurate path searching, reflection, and diffraction energy calculation for electromagnetic wave propagation.

It is applicable only to C-band, and not mmWave.

It offers higher level prediction accuracy.

Explanation
The Rayce ray tracing model is a propagation model that computes propagation paths using 3-D environment geometry 3. It is based on the shooting and bouncing rays (SBR) method, which launches rays from the transmitter and traces their reflections and diffractions until they reach the receiver or are attenuated below a threshold 4. The Rayce ray tracing model offers more accurate path searching, reflection, and diffraction energy calculation for electromagnetic wave propagation than other models, such as empirical models or deterministic models 5. It also offers higher level prediction accuracy, especially for massive MIMO systems that use beamforming techniques 6. The Rayce ray tracing model is not applicable only to C-band, but also to mmWave and other frequency bands 7.

QUESTION 43

QUESTION 49
What are characteristics of eCPRI links?(Select All that Apply)

They are based on the TDM mechanism.

They require dock synchronization.

They are based on the IP mechanism.

They require AAU support.

Explanation
According to the eCPRI Specification V2, eCPRI links have the following characteristics:
They require clock synchronization: eCPRI links use Ethernet as the transport layer, which does not provide inherent synchronization. Therefore, eCPRI links require external clock synchronization methods, such as IEEE 1588v2 Precision Time Protocol (PTP) or Synchronous Ethernet (SyncE).
They are based on the IP mechanism: eCPRI links use IP as the network layer, which provides routing and addressing functions for eCPRI messages. eCPRI links can use either IPv4 or IPv6 protocols.
They require AAU support: eCPRI links connect between Radio Equipment Control (REC) and Radio Equipment (RE) in a base station. AAU (Active Antenna Unit) is a type of RE that integrates RF and antenna functions in one unit. Therefore, eCPRI links require AAU support to enable flexible functional split options and reduce fronthaul bandwidth requirements.
eCPRI links are not based on the TDM mechanism because they do not use fixed time slots to transmit data.
Instead, they use variable-length packets to transmit data according to different service requirements.

QUESTION 50
In order to achieve ideal coverage, what is the clearance requirement around an antenna?

1-5m

50-100m

5-10m

5000-10000m

Explanation
In order to achieve ideal coverage, there should be a clearance zone around an antenna of at least d, where d is the Fraunhofer or Rayleigh distance at which the near/far-field transition zone exists 17. This distance depends on the largest dimension of the antenna, D, and the operating wavelength, \uF06C. Ideally, D should be at least a half of a wavelength, which gives a minimum clearance zone of a half-wavelength. For example, at 2.4 GHz, the wavelength is about 0.125 m, so the minimum clearance zone is about 0.0625 m. However, in practical situations, this clearance zone is often compromised and the effects must be determined through simulation or empirical measurement 18. A general guideline is to have a clearance zone of 5-10 m around an antenna to avoid significant degradation of performance 19. Therefore, the best answer is C.

QUESTION 51
In SA networking, the mobility between adjacent cells on the same frequency can use the redirection process.

True

False

For intra-frequency mobility in SA networks, handover is the preferred mechanism. Redirection is typically used for fallback or idle-mode mobility rather than connected-mode same-frequency mobility.
