BreezeACCESS™ II
The BreezeACCESS II Broadband Wireless Access system operates worldwide in the license-free ISM band delivering high-speed wireless Internet access. Utilizing the unlicensed 2.4 GHz band permits use of the spectrum without the expense of buying or applying for a license, allowing ISPs to quickly enter and compete in the market at relatively low costs.
With an exceptionally low initial investment, BreezeACCESS II is the ideal solution for new operators wanting to build their customer base. Once the wireless infrastructure is in place, it can be scaled upward to support thousands of subscribers per cell.
BreezeACCESS II operates in Time Division Duplex (TDD) mode utilizing proven Frequency Hopping technology to deliver a solution that is highly secure, robust and reliable. Optimized for data and voice communications, BreezeACCESS II allows ISPs and ASPs to rapidly and economically deploy their networks and offer highly attractive, competitive services to their clients.
BreezeACCESS II highlights
The BreezeACCESS II Base Station Equipment allows remote Subscriber Units to communicate over the wireless infrastructure.
The BreezeACCESS II family includes a Base Station Unit and three types of Access Units with differing architectures:
Base Station Shelf with Access Unit Modules
The BS-SH Base Station Unit is a 19" chassis that contains up to seven (one redundant) BS-AU modules. The BS-AU Access Units can be synchronized to ensure optimal utilization of the frequency spectrum available. The BS-SH chassis contains one power supply with an alternative second power supply for redundancy. The BS-PS power supply modules are powered from a -48 VDC power source.
The AU-A-BS Access Unit model is comprised of an indoor module (BS-AU) and an AU-RA outdoor unit, which contains a radio unit and an integrated panel antenna.
The AU-E-BS Access Unit model is comprised of an indoor module (BS-AU) and an AU-RE outdoor unit, which contains a radio module and an RF connector for a separate external antenna (the external antenna is sold separately to the unit).
The AU-A-BS or AU-E-BS units are available with either 26dBm (HP-High Power), 17dBm (MP-Medium Power) or 2dBm (LP-Low Power) output power at the antenna port. A coaxial cable connects the indoor module to the outdoor unit and serves for the transmission of signals as well as for transferring power, management and control signals from the indoor module to the outdoor unit. Connectivity to the network is established through a standard IEEE 802.3 Ethernet 10BaseT (RJ 45) interface.
Stand-Alone "Micro-Cell" Access Units
The Stand-Alone Access unit enables the coverage of a small customer base or an area with low customer density. The AU-A-NI and AU-E-NI lines are comprised of stand-alone units, which connect to an SU-RA or an SU-RE outdoor unit. The indoor part of the Access Unit, the AU-NI, is a stand-alone desktop or wall-mountable unit.
In the AU-A-NI model, the AU-RA outdoor unit contains a radio unit and an integrated panel antenna.
n the AU-E-NI model, the AU-RE outdoor unit contains a radio module and an RF connector for a separate external antenna (the external antenna is sold separately to the unit).
