The Tondo Advantage


Dusk-to-Dawn lighting control provides light even when it isn’t necessary, wasting energy and increasing sky-glow that interferes with human and animal health.

Tondo’s Adaptive Smart Lighting delivers standards-compliant lighting levels based on vehicle, cyclist, or pedestrian demand.

This can reduce the operating costs of LED street and area lighting by as much as 70%, while reducing the impact of urbanization on our ecosystems.



Smart Cities depend on an array of connected sensors and devices to collect data, automate operations, and support decision processes. 

A Smart Lighting-enabled Smart City network is an essential first-step in enabling a Smart City vision. This enables sensor and device connectivity on a common platform, and can reduce your sensor deployment costs by over 80%.

Migrating from cabinet-controlled lighting to on-luminaire lighting also enables 24×7 electrification of the light pole. This provides a value-creating platform for EV, public WiFi, and other powered services.


Tondo’s plug-and-play and automatic configuration securely configures the lighting and network controllers  in a few seconds.

Tondo’s plug-and-play and automatic configuration eliminates the need for extensive training for installing contractors, and provides significantly lower project deployment costs.

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.
