Tottenham Hotspur

 

U.K. soccer club Tottenham Hotspur has inaugurated its new stadium in London earlier this year with free high-density Wi-Fi and mobile coverage in all areas.

The club selected wireless advisory firm Real Wireless as well as communications equipment suppliers and installers to carry out the connectivity project.

Totthenham Hotspur said that the new stadium features mobile voice and data services designed and installed by Shared Access for customers of U.K. carriers Vodafone, O2, EE and Three – as well as wireless emergency and support services and Wi-Fi.

The main aim of the connectivity project was to ensure that the stadium design included provision for all the wireless services necessary to deliver the best-connected experience for fans and operational staff in and around the stadium, the club said.

This includes 2G, 3G and 4G technologies as well as PMR for support services, TETRA for emergency services and Wi-Fi.

Tottenham Hotspur highlighted that sufficient space, power and air conditioning needed to be made available in the building design to accommodate the mobile operators’ equipment and the various elements of equipment required for a distributed antenna system (DAS).

Mobile services are provided by antennas located in discreet positions within the roof structure. The new stadium will host a range of non-sporting events, including concerts, where pitch coverage is required.

Also, the club said that data capabilities are widely available across all areas including the main pitch, concourse, media areas, hospitality areas, conferencing suites and offices. A medium-data-rate service covers the basement and parking areas, while a low-data-rate service is available for the stairwells and plant rooms.

The system is comprised of a hybrid active/passive DAS, joint Operator Specifications (JOTS)-compliant 2G, 3G and 4G, allowing connections for all mobile network operators, 164 internal antennas including 48 pitch and bowl stadium antennas, six macro antenna locations providing external coverage and 19 low level external antennas providing podium coverage, over 45,000m coaxial cable, over 25,000m of individual fibers, 2,348 passive components, 9 master unit racks (POI), 172 Low power remote radio units and18 High power remote radio units (macro).

 

Banc of California Stadium

 

U.S. firm Mobilitie has installed its neutral-host DAS at the Banc of California Stadium, home of the Los Angeles Football Club (LAFC).

Mobilitie said the DAS solution was deployed in three months. The firm also said that the  network is integrated and optimized with all four major wireless carriers.

The 25-zone DAS network includes 160 antennas and more than seven miles of cabling, enabling nearly 1.5 million-square-feet of wireless coverage throughout the seating areas, suites, concourses, and parking lots. The system also features a network layout for field-level coverage. Mobilitie highlighted that the configuration provides increased upload and download speeds, seamless connectivity, and improved reliability.

 

PalaLottomatica arena

 

European wireless infrastructure provider Cellnex has installed and tested its multi-operator DAS at Rome’s PalaLottomatica sports arena.

The PalaLottomatica, designed in 1960 for the Olympics Games, is the largest events venue in the Italian capital.

The layout and design of the large circular central arena, which is 45 meters in diameter and up to 35 meters high, was a significant challenge for providing sufficient cellular network connection. Cellnex said its solution offers stable and dedicated multi-operator coverage, including on the stands of the arena, in the press area and in the various dedicated indoor areas such as conference rooms and administrative offices.

The DAS installed by Cellnex makes it possible to broadcast signal from the main national mobile operators with 2G, 3G, 4G and 4.5G technologies and is already enabled to handle 5G technologies in the future, the company added.

Cellnex also said that the contracts agreed upon with the operators, which are valid up to nine years, cover design, supply, installation, testing and maintenance of the infrastructure, as well as infrastructure supervision and optimization services.
