Advantages of Shared Carrier | Disadvantages of Shared Carrier
This page covers advantages and disadvantages of Shared Carrier. It mentions Shared Carrier advantages and Shared Carrier disadvantages.
Introduction: As shown in the figure shared carrier concept helps in sharing the same bandwidth of frequency spectrum among more than one RATs. Figure depicts sharing of spectrum by GSM and LTE RATs (Radio Access Technologies).
The concept is also utilized for simulatenous use of LTE terminal in VoLTE and data modes.

Advantages of Shared Carrier
Following are the advantages of Shared Carrier:
➨Due to sharing of spectrum system becomes more bandwidth efficient.
Hence resources are allocated more efficiently.
➨It does not require any additional equipments as same radio hardware can be
used by different RATs with the control of RF and baseband parts appropriately.
➨The use makes
fast call establishment.
This is due to less signaling overhead because of
no forced re-direction between the carriers.
➨In LTE, it uses same set of SIB configuration for both the
carriers.
➨This concept is less susceptible to human errors
during the eNB ( i.e. base station ) provisioning.
Disadvantages of Shared Carrier
Following are the disadvantages of Shared Carrier:
➨It will have more complex configuration of measurement
report to ensure accurate triggering in inter-frequency handover
scenario.
➨It requires complex VoLTE QoS requirements at network side
and at UE side to meet resource requirements for VoLTE users.
