Macro Reduction for DAS & Small Cell Savings

Proper macro cell reduction brings numerous values in terms of engineering quality and cost savings for Distributed Antenna Systems (DAS) design, deployment and performance. Engineering teams need to focus on macro cells interference mitigation to any iDAS, oDAS or small cells network during the initial design. Macro cells often were designed to provide the coverage at the venues with new DAS. In order for the new solution to effectively offload traffic and provide the network quality it needs to be on average 7-10dB stronger.

Re-Allocating Spectrum

Low band spectrum (400, 700, 800, 900MHz) provides clear improvement to network coverage over high band spectrum (1800, 1900, 2100, 2600MHz) for wireless networks. Low band spectrum can give twice the coverage radius of a high band site while at the same time providing 6-10dB improved signal strength at the same point. The drastically greater coverage provided by low band spectrum may in tern be offset by increased noise levels at peak traffic times. It is best to offset low band systems with corresponding high band implementation of the same system.

Measuring Network Voice Quality

With the purpose of maximizing spectral efficiency and allow for network carrier aggregration, the roll-out of VoLTE in existing LTE networks is a critical step. With the introduction of any new voice technology, there is a need for measuring the actual voice quality of the network. This is the complete end to end voice quality rather than the method on mature networks of evaluating the quality of the radio link. The MOS (Mean Opinion Score) is required to determine the customer experience.

RF101 - The Antenna Path - More than the Antenna

The point where the rubber meets the road in wireless networks is the antenna. The only thing is the before we hit the antenna, we have the entire antenna path which consists of various opportunities for error and issues. From external interference, to Passive Intermod (PIM), to actual faults in the path. Once the issue has been identified in the antenna path itself and not the external RF environment, there is the potential for a large variety of antenna path component combinations including fiber, coax cables, duplexers, diplexers, connectors, antennas, RETs, TMA.
