Deep Dive Webinar : How to design better wireless networks for stadiums

As of 2014, 934 stadiums worldwide have 30,000 or more seats: 228 in North America; 129 in Central and South America; 243 in Europe; 98 in Middle East and Africa; and 236 in the APAC region. The USA alone has 217 stadiums with 30,000 seats or more, and about two thirds of these are used primarily for American Football.

While RF coverage at open air stadiums may be provided by surrounding macro networks, such densely populated venues require exceptional signal quality and enormous capacity to support 4G data usage. These requirements are best fulfilled by building a wireless network inside the stadium, with its own cluster of NodeBs /Base Station sectors.

Designing an in-building wireless network for stadiums presents a unique set of challenges, such as:

Stadium sectorization planning
3D modeling of multilevel stadium
Detailed site survey
Sector overlap management
Macro interference management
Capacity dimensioning
Defining RF coverage area
Passive intermodulation (PIM)
Macro handoff management

Underground Wireless Design for Rapid Rail Transit: Challenges and Best Practices

Most subway routes in core urban areas are located deep underground, where macro cellular coverage is non-existent. In big cities worldwide, hundreds of thousands of commuters depend on the subway (or Métro, MTR, MRT, U-bahn, Underground, etc.) on a daily basis. They need dedicated wireless networks to stay connected. First responders also need reliable public safety networks in subways stations and tunnels. Subway systems are one of the most challenging environments for wireless network design.

This detailed case study covers topics like:

3D modeling of multilevel transit stations
Capacity dimensioning for rush hour
In-building system sectorization
Uplink noise control
Equipment location (ease of maintenance vs. installation cost, vandalism concerns)
Environmental challenges (metallic objects, damp conditions, AC instabilities)
Dependence on simulation due to inaccessibility to real environment (24/7 subway service)

Connecting the Corporate HQ – CASE STUDY

A business campus is the home away from home to millions of busy professionals around the world who increasingly demand constant and seamless connectivity.

Emails, video conference calls, and heavy downloads are just some of the actions that business people do on their mobile phones daily. Strong, reliable and fast wireless connectivity is no longer a nice to have at the workplace – it is a MUST.

But designing the wireless network for business campuses presents unique challenges, including:

High residual macro interference at higher floors from macro signal;
Containment of the indoor signal;
Overlapping in-building coverage for buildings in close proximity;
Multi-level 3D building modeling;
Quality coverage and seamless handoff for stairwells and elevator shafts.

This case study goes over the detailed challenges and considerations when designing a DAS for a business campus, while taking into account 4G network performance requirements.
