Across the globe, BAI Communications delivers high-quality communications infrastructure to large-scale transit systems, improving outcomes for transit operators and enhancing the travel experience for commuters.

We are an independent communications infrastructure provider helping wireless carriers, transit authorities and governments boost productivity.

In Toronto

We have funded, designed and built the cellular, Wi-Fi and fibre optic network for the Toronto subway. Here we provide Wi-Fi and DAS for 75 stations, encompassing all 79 platforms, mezzanines, walkways, passageways and stairs through the Toronto transit system.

Cellular coverage solutions

Our high-capacity 3/4/5G or private network cellular solutions enable transit passengers to stay connected. Our cost-effective, well-engineered solutions are predominantly within or adjacent to high-traffic environments such as:

  • Stations, tunnels and the rail corridor
  • Transport station shops, precincts and malls
  • Large commercial buildings
  • Areas adjacent to the rail corridor (small and macro cell solutions)

Wi-Fi coverage and IP solutions

Our transit Wi-Fi and IP solutions enable passengers and transit staff to stay connected wherever they are.

Public Wi-Fi network
For transit riders in Toronto, TCONNECT Wi-Fi is accessible across all four major transit lines in the city and currently handles nearly 200,000 user sessions each day (August, 2018). The ad-supported model allows BAI to provide the service at no cost to users or to the transit authority.

Private networks
Enterprises and governments benefit from high-quality, secure, private Wi-Fi and IP networks with their own SSID and dedicated bandwidth.

Transit authorities can unlock new revenue streams with connectivity for digital advertising screens and personal devices, and leverage our expertise in commercialising the network structure.

Enhancing transit experiences

Our network enables us to assist with solutions that improve security, and enhance the experience of commuters.

Powering applications
The Toronto Transit Commission (TTC) launched the SafeTTC app in 2017, which is supported by BAI’s network and helps users report harassment by sending images silently to the authorities. This also supports the TTC’s efforts to reduce unnecessary use of alarms on trains.

Closed-circuit television
The network can enable drivers, station and central monitoring personnel to monitor platform edges, doors and the track, which helps keep passengers safe.

Passenger Information Systems
Passengers can make better decisions about their travel options and view critical information through BAI’s network connectivity to platform video screens and their associated ‘train arrival’ countdown clocks.

Fibre solutions

Private circuits
Wireless carrier customers and transit authorities stay connected and productive with high-capacity fibre and IP connections between wireless and fixed communications applications, and customers’ networks.

Wireless carrier fibre backhaul
To ensure smooth communications, enrich customer journeys and limit any downtime when things go wrong, carriers can have redundant fronthaul/backhaul fibre connectivity between transit facilities and their core.

Transit operations solutions

Fare payment
Passengers can pay quickly and easily via wireless fare payment systems using their fare cards. Fare payment providers are able to provide this service thanks to our IP connection to the ticket gates. This leads to less fare evasion and provides transit authorities the ability to track fares and passenger numbers more accurately.

Private networks
With dedicated private wireless networks, transit operational groups can operate Wi-Fi, two-way radio, VOIP apps and connect to the internet more securely (as it is on a private network) and cost effectively (as it is using existing infrastructure).

Data analytics
Predictive data analysis including passenger counting and location heat maps, help transit authorities make better decisions regarding traffic management and security.

Base station hotels

Our centralised, controlled, secure co-locations incorporate RAN, DAS and Wi-Fi headends, and wireless carrier equipment that connects to stations, tunnels and the above-ground networks. Located separately from transit real estate, the ‘hotels’ host a mix of inbuilding, small cell and macro coverage solutions enabling network virtualisation, easy maintenance access for wireless carriers and improved interference management.

IoT solutions

Transit authorities are focused on better asset management, efficient systems, and keeping customers informed. Our networks are enabled to provide IoT services such as asset monitoring, preventative maintenance, security, environmental monitoring as well as way-finding and navigation.

Design and construction

Our teams are experienced in designing, testing and deploying connectivity systems in and around the transit environment and other complex venues with a focus on timely, safe and high quality solutions.

Maintenance and network operations

Passengers stay connected to what matters to them with the help of our dedicated teams who ensure critical services and devices are operated, and maintained continuously in the 24/7 environment of a transit system.
