Improve Station Safety and Security

Smart lighting and the appropriate selection of lighting intensity, color temperature, and coverage can make a significant difference in whether passengers feel welcome, safe, and secure, and deter crime.

But even great lighting design needs great lighting controls to implement. Ridership isn’t static, and traffic changes over time, requiring lighting controls that can adapt quickly and easily.

Smart lighting enables you to serve the needs of your passengers while ensuring you remain standards- and best-practices compliant.

Lighting in stations is found in several studies to be important for the perception of and is often found to be one of the most essential characteristics affecting safety in the stations. This also concerns the area around the station such as car parks. [Studies have] found that especially young women felt unsafe in environments with poor lighting.

Automated Configuration


Save on project deployment costs, eliminate in-the-field configuration issues, and reduce your risk of project delays.

Once physically connected, all Tondo controllers automatically sense the type of roadway lighting they are connected to, and communicate back to the Tondo Cloud-IQ Smart Lighting Management System to apply the correct lighting profile in less than 10 seconds.

The Tondo Mobile-IQ app for Android and iOS is also provided for lighting technicians in the field to perform testing and in-field configuration changes if they wish.

If you can save 10 minutes for every installed light during deployment, those costs can add up to huge project savings, and reduce the risks to your project timeline.

Cryptographic Security for Every Device


Tondo’s team designed every one of their devices with the expectation that bad actors will want to gain access.

Every device contains a dedicated “cryptographic chip” containing the most advanced physical and information-security protection available today.

Our cryptographic chip protects devices throughout the supply chain and over-the-air update process, providing true end-to-end security through to your management console.

Our security architecture goes beyond the 30 year-old software-based certificate security used by other companies, and gives each device a unique, continuously changing secure key protected in a secure hardware vault.

Normally open(NO) and Normally closed (NC) are terms used to define the states that switches, sensors or relay contacts are under when they are not activated.

A NO contact or a normally open contact is the one that remains open until a certain condition is satisfied such as a button being pressed or some other manner of activation such as those based on temperature, pressure, etc.

A NC contact or normally closed contact is the exact opposite of NO contact by function. It remains closed until a certain condition is satisfied.

Lighting control cabinets typically control a group of street lights or advertising signage from a "control cabinet". These controls have historically provided on-off functionality based on the time of day using an "astronomical clock"-based switch or daylight photosensor. Lights are controlled in groups with no individual control over a specific light.

Although new controllers such as Tondo's Edge-IQ controller have replaced the cabinet-based approach with new technologies that include advanced dimming, remote cloud-control, and support for functionality including sensors and switches, there are many outdoor lights and signs that do not support on-lamp control. Tondo's Cabinet-IQ controller provides new advanced IoT technology support for existing cabinet-controlled lighting.

CAT-M/LTE-M and NB-IoT are similar but have differences that may make one suitable over another, or simply selected based on the support for one or the other that is available in your area.

NB-IoT uses a narrow bandwidth of 200 kHz, where CAT-M uses 1.4 MHz. The maximum data rate for NB-IoT is ~ 250 kb per second, with CAT-M1 reaching ~ 1 Mbps. CAT-M is marginally less energy efficient than NB-IoT. Although NB-IoT has a lower speed, both NB-IoT and CAT-M are suitable for sensor communications since sensors typically do not require much bandwidth.

Both NB-IoT and CAT-M1 are supported under the 5G technology specifications and therefore are ideal for selecting as a standard for sensor communications.


CAT-M wireless (aka LTE-M) is a low-power wide area network (LPWAN) cellular data transmission standard that operates over the data and physical layer. CAT-M was designed for IoT projects, with an average upload speed between 200 kbps and 400 kbps.

Eddystone is an open-source Bluetooth advertising protocol originally designed by Google. It can be used by mobile device applications to deliver improved proximity-based experiences that include applications such as Google Maps.

These packets can be discovered with any Bluetooth LE APIs such as Core Bluetooth on iOS, or android.bluetooth.le on Android. You can also use them with Google’s Nearby Messages API, which can be integrated into an iOS or Android app, and receive “messages” in those apps when a person enters or exits a range of beacons.

RS-485, also known as TIA-485(-A) or EIA-485, is a serial communications standard.

Electrical signalling is balanced, and multipoint systems are supported. Digital communications networks implementing the standard can be used effectively over long distances and in electrically noisy environments.

This table describes the differences between 3G, 4G, and 5G cellular communications standards.

4G devices will work on 4G LTE networks and the earlier cellular technologies, including 3G, EGPRS, and 2G.

Smart city sensors require very little bandwidth, and 3G EGPRS and 4G LTE can easily support the required data rates.

5G networks are relatively new, and most 5G deployments use a combination of 4G and 5G networks.
