DIB-500 R4.1 Product description
Antenna coupling variants
18 Site Requirements 90DIB500R41SR_FCC02 – 99.1
3.1 Antenna coupling variants
The DIB-500 R4.1 is available with different antenna coupling systems. The selection of
the corresponding antenna coupling system depends on the network requirements.
The following antenna interfaces are available for different network requirements:
| Hybrid variant
– Compact design
– As many as eight carriers per network element (two equipment racks with four
carriers each)
– Highly flexible in the frequency selection
– flexible frequency change
| Cavity variant
– As many as eight carriers per network element (two equipment racks with four
carriers each)
– higher transmitting power than hybrid variant
| High-power variant
– up to two carriers per network element,
– Higher transmitting power than hybrid and cavity variants
| FlexibleTx variant
– only equipped with Rx path
– up to four carriers per network element,
– high flexibility due to the use of project-specific antenna coupling systems
– site-specific provision by the network operator
Antenna diversity is available for optimal reception properties.
