Case Study - Hospital in Christchurch

The Hospital is one of the largest private hospitals in New Zealand and one of the most modern in terms of equipment and technology. Situated in the city of Christchurch, the Hospital caters to a large range of health services. The 2011 earthquakes caused considerable damage to the hospital buildings and the hospital has seen significant redevelopment which is still ongoing today.

Mobile connectivity is a crucial part of our everyday communication, entertainment and also as part of the greater business requirement for running the hospital safely and efficiently. The Hospital offers a first-class experience to their customers, patients, staff and consultants. It was identified very quickly that poor mobile coverage existed and so an immediate decision was made by the hospital to rectify the issue.

Installation Challenges

Teltrac Communications performed the site audit measuring signal level strengths throughout the new buildings which confirmed the connection issues users were reporting.

The buildings were large multi-floor structures so the running of cables and pathways needed to be planned out carefully well in advance with technicians needing to work around the schedules of the hospital to ensure no disruption occurred to staff and patients during the installation.

The Issue

As the buildings were rebuilt it was identified that the mobile signal was very weak to non-existent within these buildings. This was caused by the construction materials being used; steel, concrete and glass, which make it extremely difficult for a mobile signal to penetrate.
When radio signals pass through dense materials such as walls, buildings or even furniture within a building, they suffer attenuation. It is particularly applicable to cellular communications where the radio signal attenuation is more pronounced for the higher frequency mobile bands.

All carriers were affected, 2degrees, Vodafone and also Spark.

 

The Products

The Cel-Fi SOLO for SPARK  improves 3G/4G/LTE cellular service by eliminating dead zones and dropped calls. With up to 100dB of gain, it is the most powerful carrier-grade solution available. The Cel-Fi SOLO covers up to 1,500 square meters of indoor space per system.

The Cel-Fi GO2 for Vodafone NZ Smart Repeater is the ideal product to boost and distribute a 3G/4G mobile signal within a building. Supporting voice and mobile internet for multiple mobile devices, dropped calls and slow internet are a thing of the past.

The Cel-Fi GO2 for 2Degrees Smart Repeater is the ideal product to boost and distribute a 3G/4G mobile signal within a building. Supporting voice and mobile internet for multiple mobile devices, boosting your indoor mobile coverage has never been easier.

Blackhawk Ceiling Dome 698-4000 2/5dbi Antenna This is the ideal indoor antenna for Cel-Fi repeater systems. Indoor dome antennas are designed to be mounted to the ceiling of your building to provide consistently distributed mobile phone service from your Cel-Fi repeater/booster. The antenna is compact with a visually unobtrusive design similar to a smoke alarm.

Mars Panel Antenna  The antenna is aesthetic, small and has an unobtrusive profile that blends easily with any environment and can be easily used for Indoor and features different mounting options.

The Blackhawk Ultraband Parabolic Grid Antenna is designed to provide maximum gain across the entire 3G, 4G, and 5G bands on all New Zealand networks. The patented one-of-a-kind design allows for very high gain and directionality on all frequencies between 600 MHz and 6500 MHz. Ideal for areas with very low or noisy signal to maximise the input signal for cellular modems or Cel-Fi repeaters.

The Solution

The solution was installed by Teltrac Communications, an industry Technology Solutions Provider, with capabilities across a broad range of infrastructure, commercial and residential technology solutions and services.
The Hospital project was the first major site in New Zealand to have this particular solution boosting the coverage of all three carriers within the same space. Much thought went into the design to ensure that there was no interference between the carriers and that all spaces had adequate coverage.

The Outcome

As soon as the solution was implemented The Hospital noticed an instant improvement in the mobile coverage for all three carriers across all target coverage areas. Patients and their visitors were able to communicate with loved ones and use their devices for entertainment during their stay, whilst the staff at the hospital were able to carry out their jobs safely and effectively.
