Flexible and Future Proofed
Whether your application calls for band selective, channel selective or a combination of both, the Node A platform is capable of meeting the needs of any single band/single operator requirements or can be expanded to address full multi-band/multiple operator applications.
The A stands for technology Agnostic meaning regardless of protocols, spectrum reassignments, or whatever new wireless technologies may emerge, modification and expansion of your system will be quickly achieved.
By design, the Node As modular scalable architecture allows the user to quickly modify, upgrade or expand the repeater platform by simply adding additional RF cards and software features. The platform is available in medium and high power classes making it ideal for driving both passive and optical distributed antenna systems for medium to large facilities.
Several innovative software functions, such as an embedded spectrum analyzer for setup and interference logging, and uplink muting, are available through optional software keys. In addition, Andrew Solutions provides A.I.M.O.S., a comprehensive OMC. The implemented standard SNMP-based MIB also allows easy integration into a third-party OMC.The Node A is available in software optimized platformsfor public safety, commercial, or mixed applications.
Performance Assurance The patented architecture utilizes state-of-the-art technology to offer significantly higher dynamic range and processing power than any other digital repeater on the market. The high dynamic range allows operation in the presence of strong transmitters/interferers without the need for external filtering or attenuation. Internal filters are constructed on the fly through the user interface to adapt to new requirements or changes in the outdoor environment, without the need todownload external files.
When using the advanced filtering capabilities of the Node A only desired signals are transmitted, which results in optimum utilization of the Node As output power capacity. While amplifying the desired signals, the undesired signals are not amplified by the Node A and potential interference issues are mitigated. The resulting coverage footprint is greatly increased and is not affected by changes in the outside RF environment. Also, with the undesired signal levels significantly reduced, the potential of nearby base station sites degrading coverage is eliminated.
The high power RF cards make use of an advanced feedforward power amplifier technology which drastically reduces power consumption and heat dissipation. The lower power consumption means increased system reliability, and reduced thermal loading on the equipment room and decreased battery backup requirements. The Node A is fully compliant with all applicable regulatory standards (e.g., FCC, ETSI, IC, etc.).
