BreezeACCESS OFDM

BreezeACCESS OFDM_0606

Powering provider performance

Featuring the same field-proven and mature rich-feature set as the well-established and highly successful products in the BreezeACCESS portfolio, BreezeACCESS OFDM is the ideal point-to-multipoint broadband wireless access system for Operators offering high-bandwidth IP-based services. 

Leveraging the excellent multipath resistance capabilities of OFDM technology, BreezeACCESS OFDM enables operation in near and non-line-of-sight (NLOS) conditions, which enable Operators to reach a previously inaccessible and broader segment of the subscriber population, with fewer Base Stations. These advanced capabilities radically reduce the initial cost of investment, installation costs and time to market while increasing Operator revenue potential. 

Operating in the licensed 3.5 GHz frequency band, BreezeACCESS OFDM leverages Orthogonal Frequency Division Multiplexing technology to deliver high data rates, high spectral efficiency and immunity to interference and multi-path conflicts. 

Delivering data burst rates of up to 12 Mbps, BreezeACCESS OFDM ensures always?on connectivity to a full range of IP-based services, including fast Internet, VLANs, VPNs and toll quality VoIP. 

BreezeACCESS OFDM provides an instant and independent infrastructure, which is immediately deployable with lower infrastructure construction and operating costs than any other solution on the market. 

BreezeACCESS OFDM highlights 
     
  • Orthogonal Frequency Division Multiplexing (OFDM) technology ensures high data rates, high spectral efficiency and immunity to interference and multi-path conflicts.              
  • Near and non-line-of-sight (NLOS) capabilities.              
  • Demand-based build-out, easy installation and low cost of ownership              
  • OFDM enabled high base station data capacity - 72/192 Mbps can be achieved over typical frequency allocations of 10.5/28 MHz respectively.              
  • Packet switching technology optimized for “always on” connectivity.              
  • Independent uplink/downlink transmission settings for CIR/MIR              
  • Adaptive modulation              
  • Advanced filtering capabilities              
  • End to end QoS with 802.1p and IP ToS              
  • VPN support with 802.1Q VLANs              
  • Highly cost effective infrastructure and customer premises equipment.              
  • Easy-to-use SNMP-based remote management system

Customer Premises Equipment

Building bridges to BWA, the BreezeACCESS OFDM Subscribers Units provide a bridge between the wireless and wireline media, supporting up to 512 MAC addresses. The SUs connect to the subscriber's data equipment via a standard IEEE 802.3 Ethernet 10/100-BaseT (RJ 45) interface.

Indoor/Outdoor Units
The BreezeACCESS OFDM indoor/outdoor Subscriber Units include an indoor desktop or wall-mountable unit, containing the processor, modem, Ethernet interface and the IF radio component. The indoor unit is powered by a desktop Power Supply Unit, supplying 24 Volts. 

The outdoor unit comprises a radio module and integrated flat panel antenna. The indoor and outdoor units are connected via a 50-ohm coaxial Intermediate Frequency (IF), relaying 140 MHz IF signals between the units. Data, power, management and control signals are transmitted between the indoor unit and the outdoor unit via this coaxial cable.

Base Station Equipment
Delivering superior flexibility in architecture and network deployment, the BreezeACCESS OFDM Base Station equipment ensures demand-based scalability combined with flexible modularity.

Base Station Shelf
The 19" 4U Base Station chassis (BS-SH-OF) provides 8 interface slots and two slots designated for power supply modules. The Base Station is powered by a -48 VDC power source, with a back-up module ensuring complete fail-safe redundancy. Up to six BS-AU modules can operate simultaneously, with two supplementary slots reserved for future use.

Indoor/Outdoor Access Units
The BreezeACCESS OFDM indoor/outdoor AU-E-BS-OF Access Unit configuration includes an indoor module and outdoor unit.

The AU-NI-BS-OF indoor unit is a network interface module that fits in the base station chassis, containing the processor, modem, Ethernet interface and IF radio module. The AUs connect to the network backbone via a standard IEEE 802.3 Ethernet 10/100-BaseT (RJ 45) interface.

The indoor and outdoor units are connected via a 50-ohm coaxial Intermediate Frequency (IF), relaying 140 MHz IF signals between the units. Data, power, management and control signals are transmitted between the indoor unit and the outdoor unit via this coaxial cable.

The outdoor units feature two antenna configuration options, delivering enhanced network flexibility, as follows:

  • AU-A-BS-OF units: Comprise a radio module and integrated flat panel antenna.            
  • AU-E-BS-OF units: Include a radio module and RF connector for a separate external antenna.
