By including TAC data in our extensive database of device profiles, our customers have access to a full list of device attributes, from Release Year and Price Band to Screen Size or Device RAM. This data can be used to drive business growth from Marketing and Customer Service departments all the way to BI and Engineering.
Of all GSM SIM activity from devices with screens, 98.44% comes from devices we have TAC data for. Coverage is a measure of real-world active devices. It doesn't include devices that were never launched or are no longer active on any network.
Where other solutions, which only use a single source of data, may claim a higher coverage, the question to ask here is, “has that data been verified against multiple verified sources for consistency and accuracy?”.
What about the other 1.56%?
The other 1.56% is made up of:
- Devices that are only contained in a single data source and can't be collaborated with another data source
- Devices that are not sufficiently active to warrant researching and adding to the data
- Devices with TAC codes which cannot be verified against multiple data sources. For example, some manufacturers don't follow the correct procedure for allocating TAC codes.
That said, our data operators are investigating and mapping more TAC data every day to increase our TAC coverage.
Duplicate TAC Codes
In certain circumstances, TAC data could relate to multiple device models. This is one of the reasons why we utilize multiple verified sources. Instead of relying on one source of the truth, TAC data is cross-checked to ensure the most accurate data is provided to 51Degrees customers.
Our team manually researches and maps TAC data to device profiles, using multiple verified sources taking extra care to ensure the highest levels of accuracy are maintained at all times.
A Complete Solution
We provide a single, unified database you can rely on, containing 234 device properties and indexed by TAC, Web, and Apps. This means that network operators can have access to the same device specification data whether it's coming from Wi-Fi or a mobile network connection.
The data is available to download in a format and at a frequency that's convenient to you. This will allow you to easily integrate TAC data into existing data and analysis tools. The same data can be used with User-Agents and native application keys to monitor WiFi and cellular networks, as well as web traffic and application installs.
Does every device have a TAC code?
No, not all devices have a TAC code. TAC codes are only allocated to GSM wireless devices with a SIM card, so you wouldn't find a TAC code on a desktop computer or Wi-Fi only tablet. The other type of device that would not have a TAC code, is a CDMA-only device. For example, the iPhone 4 model A1349 which was only ever released for CDMA. Where a TAC code cannot be assigned ‘N/A’ is returned.
