As technology continues to evolve and advance, industry standards and certification testing also change. Comprised of representatives from CTIA member companies, several working groups monitor and update certification requirements and tests as appropriate. These working groups focus on a variety of wireless topics such as batteries, 4G/LTE interoperability and Bluetooth® compatibility.
Certification programs provide carriers and manufacturers peace of mind by leveraging expertise from CTIA members across the ecosystem and harmonizing processes with partner organizations, including Bluetooth Special Interest Group, CDMA Certification Forum, IEEE, PTCRB and Wi-Fi Alliance®.
Batteries Bluetooth Compatibility
CTIA manages a program to permit operators and their suppliers to validate a Lithium Ion battery's compliance with the IEEE Standard for Rechargeable Batteries for Cellular Telephones, IEEE Std 1725™ - 2011 and the IEEE Standard for Rechargeable Batteries for Multi-Cell Mobile Computing Devices, IEEE Std 1625™ - 2008.
In partnership with the Bluetooth Special Interest Group, CTIA manages a program to improve the interoperability between cellphones and Bluetooth devices, including hands-free systems in cars and headsets. Code Division Multiple Access (CDMA)
Code Division Multiple Access (CDMA) is an underlying technology used by some U.S. wireless carriers to transmit wireless calls. Verification of a wireless device's compliance to this technology is managed under the CDMA Certification Forum (CCF). Manufacturers may seek a "CTIA Certification Market Endorsement" as a part of that process. Hearing Aid Compatibility (HAC)
As part of the testing process, handsets purported to work with hearing aid devices with minimal interference are rated on their compatibility. If a wireless handset is hearing aid compatible, it receives a rating based on the level of compatibility with hearing aid devices that use the acoustic or magnetic coupling modes. 4G/LTE Interoperability
This testing helps network operators ensure that a mobile device works properly on 4G/LTE networks. Over the Air Performance
Mobile devices are tested for their transmit/receive performance. RF Performance of Wi-Fi Mobile Converged Devices
Building upon the Over the Air Performance test plan, this test plan evaluates the interaction between cellular and Wi-Fi signals in devices such as smartphones that incorporate both these technologies.
