Mobile operators are constantly challenged by rapid changes in the industry. Growing number of network users and other point-to-point radio links operating on the same frequency are amongst the most common aspects regarding interference issues. In order to resolve problems in backbone point-to-point radio network, as well as, to improve the existing network quality, LMT uses Spectrum Compact analyzer. Unlike other similar devices used for interference problem detection, SAF’s Spectrum Compact offers unique technical characteristics which are supplemented with easy to use interface and sleek design.
LMT is the largest mobile service provider in Latvia, whose main shareholder is TeliaSonera. Their services operate on more than 1190 base stations providing network coverage on the entire area of Latvia. Data transmission is one of the main services provided by LMT. In order to remain its market leading position, LMT continuously improves its network capacity. To maintain wide geographical coverage, data transmission speed and quality LMT has to resolve any problems that are caused by interference.
Location: Latvia, entire area
Link distance: 600 m up to 35 km
Frequency bands in use: 6, 13, 18, 23, 26, 32, 38 GHz
Antenna diameter: 0.3 m-1.8 m
“Our main challenge is to increase base station capacity by detecting and eliminating any interference problems in backbone point-to-point radio network. Spectrum Compact is a great tool, that has significantly decreased our intereference problems."
Gunars Afonins, Deputy Head of Transmission Devision | LMT
Dense urban deployment and the growing demand for telecommunication services create various interference problems for mobile operators. Resulting in degradation in signal quality and strength, mobile service providers are constantly researching new ways to enhance network and signal quality. In order to increase data capacity, LMT uses XPIC in combination with other links that operate in n+n configurations, making it more challenging to sustain a superior connection to its clients. On the contrary to Spectrum Compact, other devices with similar functions create an unnecessary struggle for field engineers. Inconvenient weight and size, as well as the time-consuming preparation that is required by predecessors in the field of spectrum analyzers, make it hard to resolve any problems that are caused by interference. Company’s one of the main goals is to detect free channels and resolve any interference issues that are caused by overlapping frequencies.
