Alvarion BreezeMax Macro Indoor
BreezeMAX Macro Indoor System Components Indoor Unit (IDU)
The IDU is the main chassis of the BreezeMAX base station, which establishes wireless network connections and manages bandwidth in compliance with the IEEE 802.16e-2005 wireless standard.
The IDU is designed for diversity, provides high throughput and is built according to the Software Defined Radio (SDR) approach. This creates a highly flexible platform that supports beamforming (BF) and allows for seven access unit (AU) cards and two network processing unit (NPU) cards to be hosted for redundancy support. The IDU is comprised of two main units in addition to power and management components.
Access Unit (AU):is a programmable, cutting-edge WiMAX modem card, which ensures maximum resource utilization for both personal and primary broadband access. The AU implements four transmit/receive channels, supports BF and MIMO Matrix A and B technologies and is connected directly to remote radio outdoor units (ODUs).
Network Processing Unit (NPU):is a central processing unit managing the base station components and all connected subscriber units.
The NPU can operate in either of the following two modes:
Transparent mode: which includes traffic aggregation of all access units to and from the backbone via 100/1000 Mbps network interface.
ASN-GW mode: which includes the following functions: Traffic classification and connection establishment initiation
Policy-based data switching
Service level agreement management
Overall base station, operation control and alarm management Distributed or centralized architecture
Outdoor Access Unit (ODU)
A high-power remote radio unit that connects to an external antenna, theODU provides high system gain and interference robustness utilizing hightransmit power and low noise figure. Supporting up to 20 MHz bandwidth, the ODU is scalable for future options such as increased capacity through carrier multiplexing or wider frequency bandwidths. The BreezeMAX Macro Indoor base station offers a range of ODUs featuring diverse configurations and streamlining 2nd and 4th order diversity.
