The Internet of Things is expected to be the next revolution in mobile communication, connecting billions of devices. Current cellular technology is not optimized for this massive machine-type communication (MTC). 3GPP has released requirements for new cellular-based narrowband technology specifically for IoT.

Modern cell sites have a distributed architecture, where the base-station transceiver subsystem is divided into two main elements:
1. A baseband unit (BBU) performing base band functions in the digital domain, which resides at the base of the tower;
2. and, a remote radio head (RRH)...
Quickly locate RF interference sources with advanced interference hunting techniques.
With RF spectrum proliferation, interference issues are inevitable. Interference can reduce coverage, capacity, and throughput by desensitizing receivers, increasing noise floors, and lowering signal-to-noise ratio (SNR). All of this has a major impact on user...
RF interference can reduce coverage, capacity, and throughput by desensitizing receivers, increasing noise floors, and lowering signal-to-noise ratio (SNR). These conditions can prevent the use of higher modulation coding schemes and efficient resource block allocation as LTE schedulers attempt to avoid impacted spectrum. Detecting...
Until now, cell site turn-up and maintenance have been relatively straightforward procedures-performed on one macro cell with one technology. Today, much has changed-in addition to macro cells, small cells and DAS are proliferating, both indoor and outdoor, covering 2G, 3G, 4G and WiFi.
RF and...
