AT&T has approved the Sequans Calliope 2 Cat 1bis platform, which includes the Calliope 2 chip and the GC02S1 module, for use on its commercial mobility network and FirstNet.

FirstNet is the USA’s high-speed broadband communications network built by AT&T, in public-private partnership with the First Responder Network Authority, for America’s first responders and the public safety community.

French firm Sequans specialises in 4G and 5G cellular IoT chips and modules. The GC02S1 module has achieved technical acceptance from AT&T’s lab, and the Calliope 2 chip has passed AT&T’s Adapt chipset verification programme.

Approval of the GC02S1 assures device makers that the module meets AT&T’s performance, interoperability and feature requirements. Modular approval is a core requirement giving device makers the ability to bring end devices to market faster, using the streamlined end device certification programme for both the AT&T network and FirstNet (

“We are very pleased to have these first Cat 1bis solutions from Sequans now approved for our network,” said Cameron Coursey, vice president at AT&T ( “The availability of Cat 1bis technology is of paramount importance to AT&T customers looking for efficient and reliable connectivity required by demanding IoT applications operating on AT&T’s network and the FirstNet network.”

Cat 1bis is a version of the LTE Cat 1 technology designed to reduce cost and complexity by only requiring a single antenna. It is universally available technology that has been optimised for cost and power consumption while retaining the high reliability and low latency of original Cat 1 technology. Typical applications for Cat 1bis include vehicle telematics, security and alarm systems, payment systems, and healthcare devices.

“Earning the first Cat 1bis approval from AT&T is a key accomplishment and of key importance to our customers,” said Georges Karam, CEO of Sequans. “There are numerous IoT use cases where Cat 1bis is the ideal technology choice and, now that it is approved for FirstNet, I believe we will see a proliferation of Cat 1bis applications coming to market.”

The Calliope 2 ( platform is designed for critical IoT applications. It supports the optimised Cat 1bis standard, delivers low power consumption, and can be deployed on any LTE network. It delivers high levels of security and reliability. The Calliope 2 chip is designed in Europe and manufactured in Taiwan. The Calliope 2 GC02S1 module is assembled in Vietnam. Features include:

  • Supports PSM and eDRX for ultra-low power consumption
  • Data rate up to 10Mbit/s downlink and 5Mbit/s uplink
  • Supports external SIM and eSIM as well as integrated eSIM
  • Common Criteria (CC) EAL5+ security for iSIM*
  • Compatible with Sequans Monarch 2 LTE-M and NB-IoT platform for easy migration among Cat 1, LTE-M and NB-IoT.

Founded in 2003, Sequans ( is based in Paris, France, with offices in the USA, UK, Israel, Hong Kong, Singapore, Finland, Taiwan and China.
