BROWSING: Viavi white papers and application notes

  Learn about the challenges of C-RAN, and best practices for testing   Recent advancements in radio technology have allowed service providers to deploy LTE networks using a distributed baseband architecture. Radios are installed at the top of the tower, close to the antenna, and separated from...

Current IoT communication solutions on cellular systems require too much power and cost for many of IoT’s applications. Narrowband IoT (NB-IoT) offers lower cost and lower power consumption for a more efficient network, and operates in licensed spectrum.

Quickly identify and isolate RF interference with the broadband log periodic antenna The Viavi Solutions® broadband log periodic antenna is an extremely cost-effective solution that works with an AntennaAdvisor handle and CellAdvisor base station analyzer to let technicians at any skill level quickly identify and...

A service provider eliminates interference from an unauthorized signal booster thanks to Viavi InterferenceAdvisor Mobile repeaters or signal boosters are wireless devices used to enhance coverage by amplifying and re-transmitting the mobile signals in areas of poor signal quality. At a subscriber level, with access...

To meet an increasingly diverse set of usage profiles, mobile network operators are building heterogeneous radio access networks that combine macro, small cell and WiFi technologies from different vendors across 2G, 3G and 4G. The level of diversity in subscriber requirements and the surging...

Evolving base stations have implemented cloud radio access network (C-RAN) technology to provide better planning flexibility and meet demands for ultra-high data throughput. A base station consists of two key units: the baseband and radio modules. C-RAN enables separating them so that radio units...

Conventional cell sites have radio equipment at the base of the tower transmitting RF signals via coax cables to antennas at the top of the tower. However, these coax-based feeders produce the majority of problems in cell sites due to inherent loss, susceptibility to interference, and the...

BBU emulation capability simplifies the deployment of cell-sites by verifying radio installation, configuration, and operation prior to commissioning. Download this application note to learn how CellAdvisor with RFoCPRI and BBU emulation dramatically reduces OpEx and time-to-market when deploying cell sites.

Radio equipment at conventional cell sites is located at the base of the tower, transmitting RF signals via coax to antennas at the top of the tower. However, these coax-based feeders produce most problems in cell sites due to their inherent loss and susceptibility...
