Andrew Wireless Solutions, a CommScope Inc. division, has launched a digital, multiband selective repeater that enables building cost-effective indoor coverage. Andrew's Node A RF Enhancer supports a combination of narrowband channels and individual band segments in one unit—whether 2G, 2.5G, 3G, or 4G cellular, iDEN, TETRA, VHF, or the recently auctioned 700MHz or other frequency bands. Wireless operators can use the Node A to bring all of their outdoor frequency bands into small- and mid-sized buildings, or, if used in conjunction with Andrew's Intelligent Optical Network (ION) family of products, cover large venues.
In addition to wireless operators, the Andrew Node A is ideal for other potential customers, such as building owners who need to support multiple forms of wireless communications, including mission-critical systems.
Two unique features of Andrew's Node A are its automatic gain control (AGC) and interference cancellation technologies. AGC helps prevent high power mobile devices, such as those transmitting further away from the booster, from degrading the service of low-power devices, such as those operating closer to it. The AGC also automatically adjusts system gain on per channel or per time slot basis during major emergencies, helping to avoid diminished signals when many first responders are using the system. The Node A also employs software-based digital filtering for interference cancellation, selectively rejecting unwanted signals such as harmonics and channel interfering frequencies on interleaved sub-bands.
