Location: Hospital Comarcal de la Selva (Hospital de Blanes), Blanes, Spain
Challenge: Unstable indoor mobile signal across multiple network operators
The Problem
Hospital de Blanes (Hospital Comarcal de la Selva) in Spain faced significant indoor mobile reception issues. These problems stemmed from large input signal imbalances between Movistar and other mobile network operators, namely Vodafone and Orange. The previous system could not manage these disparities, leading to saturated signal levels and unequal MNO signal balancing.
As a result, both voice and data services were unreliable throughout the hospital. This affected critical areas, including emergency units, surgical suites, and outpatient zones. These areas collectively handle over 60,000 consultations and 50,000 emergency cases annually.
The Multiboost Solution
To tackle these challenges, Multiboost deployed a PRO Triple mobile repeater system. This installation was meticulously tailored to ensure reliable indoor coverage for 2G, 3G, 4G, and 5G services across all three major Spanish operators.
Installation Details
Repeater model: Multiboost PRO Triple
Frequencies: 800 / 900 / 1800 MHz
Operators supported: Movistar, Orange, Vodafone
Voice and data coverage: 2G + 3G + 4G + 5G
Indoor antennas: 8 ultra-slim omnidirectional ceiling antennas
Outdoor antenna: 14 dBi sectorial (700–2600 MHz, 35° H/V)
Line amplifiers: 2
Results
The installation significantly improved indoor coverage for all operators throughout critical hospital zones. This enhancement enabled seamless communication for both staff and patients.
The Multiboost PRO Triple demonstrated its ability to maintain stable signal performance despite extreme input power differences between operators. This is a challenge that traditional analog repeaters struggle to manage.
Real-Time Monitoring
The following real-time monitoring screenshots from Multiboost Cloud illustrate how the Multiboost system effectively handles these variations. It ensures consistent coverage across all mobile networks.
The first chart shows Vodafone (Band 8 - 954.9 MHz) with an average input power around -42 dBm and a consistent gain of 46 dB.
In contrast, the second chart shows Movistar (Band 8 - 942.5 MHz) with an input power of -3 dBm. This is exceptionally high and would typically saturate most commercial repeaters. The difference of nearly 70 dB between Vodafone and Movistar input levels would overwhelm conventional systems. However, the Multiboost repeater managed these extremes flawlessly, delivering stable and balanced coverage across all areas of the hospital.
This screenshot highlights how Multiboost effectively handles large input power differences across mobile operators. This is a key weakness of the previously installed system. Although our repeater was operating properly, we decided to install a 10 dB attenuator to improve performance.
Performance Insights
On Band 8 (900 MHz) and Band 20 (800 MHz), Movistar signals are extremely strong (e.g. -14 dBm), while Vodafone and Orange signals are much weaker (ranging from -61 to -54 dBm).
In common systems that apply one gain setting per band, the strongest signal limits the available gain. This means weaker operator signals (those whose base stations are farther from the building) don't receive enough amplification.
Multiboost compensates for these imbalances, maintaining sufficient gain and output power for all operators, even with input differences of over 40 dB. This ensures reliable, balanced indoor coverage.
The graph above shows the Movistar signal after the installation of the 10 dB attenuator.

Conclusion
This case study proves the Multiboost system’s advanced signal handling and equalization capabilities. It excels in high-demand, multi-operator environments like Hospital de Blanes. Encouraged by the results, the hospital is planning a project expansion to include additional line amplifiers and interior antennas.
