1.5.1.2.2
Dual Carrier (Sector) 2x2
The Dual Sector topology enables a double-capacity BreezeCOMPACT. In this mode, the
BreezeCOMPACT behaves like two 2x2 eNodeB’s (double capacity vs split mode). UEs on
different geographical sectors see different eNodeB’s on different carriers. Each carrier can use
any center frequency within the product’s frequency range. For example, the
BreezeCOMPACT 1000 supports 3.4–3.7 GHz. The operator can configure one carrier for
3.405 GHz and another for 3.695 GHz. This capability enables two 5MHz carriers or two 10 Hz
carriers.
This feature is available for 5+5, 10+10, 14+14, 15+15, 20+20 MHz .

1.5.1.3
Single Geographical Sector using Dual Carrier 2x2
The Dual Carrier topology enables a double-capacity BreezeCOMPACT. In this mode, the
BreezeCOMPACT behaves like two 2x2 eNodeB’s towards the same geographical sectors at two
different frequencies (double capacity vs single carrier).
1.5.1.3.1
Dual Carrier 2x2
UEs on different carriers see different eNodeB’s on different carriers. Each carrier can use any
center frequency within the product’s frequency range (but not the same frequency). For
example, the BreezeCOMPACT 1000 supports 3.4–3.7 GHz. The operator can configure one
carrier for 3.405 GHz and another for 3.695 GHz. This capability enables two 5MHz carriers or
two 10 Hz carriers.
This feature is available for 5+5, 10+10, 14+14, 15+15, 20+20 MHz.

Dual Carrier Aggregation (Downlink)
In a case of a Compact with a Dual Carrier configuration (two carries with two different
frequencies within the same geographical sector). The Carrier Aggregation capability is
supported with selective CPE’s. The Carrier Aggregation enables optimizing Sector performance
with increased throughput per user by aggregating two radio channels in the Downlink for the
same CPE.
