Global Certification Forum announces 23% year-on-year increase in cellular device certifications

Record number of devices in the GCF 2018 certification programme:

  • Manufacturers increasing complexity of devices, with ‘average device’ now incorporating 17.3 bands and 2.6 bearer technologies
  • Increase dominated by IoT modules
  • 5G certifications began January 2019 - but GCF forecasts certifications to be low in number during 2019; and no mmWave devices

The Global Certification Forum (GCF) has announced its 2018 wireless device certification data, which shows significant increases in both the number of manufacturers certifying devices (up 14% on 2017) and the number of devices themselves (up 23%).

The GCF is a globally recognised quality mark for the interoperability of mobile handsets and wireless devices. The organisation collaborates with other dynamic leaders in standards - from 3GPP and GSMA to the NFA Forum and oneM2M - to ensure devices can operate correctly in all their target markets. The data has been announced in its 2018 white paper - available to download for free at


Highlights of the year’s data include:

Devices continue to become more complex 

The average (mean) device certified during 2018 is operational in 17.3 frequency bands, across average 2.6 bearer technologies such as GSM, 3G and LTE. This is up 29% on 2017, where the average device supported 13.4 frequency bands.

LTE growth slows significantly

In 2018, 548 (85% of all) devices incorporated LTE (fig 2). And while the overall number of devices increased significantly on 2017 levels (437 devices) proportionally it is only a marginal increase on 2017 data, where 84% of devices incorporated LTE. Notably, this represents a significant year on year deceleration in growth. In 2015 LTE was incorporated into 69% of devices, rising 7 points in 2016, 8 points in 2017 and only 1 point in 2018.

3G has a resurgence, GSM continues its decline

Unexpectedly, the proportion of devices incorporating at least one 3G band increased during 2018 (reversing 2017’s decline) and it is again the most commonly used standard with 87% of devices incorporating 3G. Despite the rise, however, there were no stand-alone 3G devices suggesting the standard will continue to decline as operators replace 3G capacity with LTE.

The penetration of GSM continues its decline. 75% of certified devices incorporated GSM in 2018, this is down from 81% in 2017 and 84% in 2016. Just 20 standalone GSM devices were certified in 2018.

IoT modules saw the fastest growth of any segmentin 2018

While smartphones again represent the largest class of certified devices and the number of smartphones certified has increased, smartphones fell as a proportion of all devices - from 55% in 2017 to 49% in 2018. This drop has primarily come from a significant growth in IoT modules, now make up a quarter (24%) of devices, up from a sixth (16%) in 2017 (fig 3).

Forecasts for 2019:

5G certifications begin in 2019, but is expected to be few in 2019

Towards the end of 2017, GCF started the development of 5G device certification to cover both the non-standalone (NSA) and standalone (SA) 5G system modes of operation. The 3GPP has yet to announce its final 5G NR specification; however, GCF is prepared for when it does – expected Q1 of 2019 and GCF certification will apply to 3GPP 5G NR implementation.


We forecast that certifications for 2019 devices supporting 5G will likely be a modest number and they will use the sub-mmWave bands. And while no certifications took place in 2018, January 2019 saw GCF’s first 5G NR test system - Keysight Technologies’ 5G Conformance Toolset.

About GCF

Global Certification Forum (GCF) enables the global wireless industry to deliver a connected world, with mobile and IoT device certification programmes that ensure quality, connectivity and interoperability, whatever the technology.


Shaping the industry since 1999 with mobile technology at its core, GCF today has over 315 dynamic members from major operators, manufacturers and the test industry, working collaboratively and in association with key industry partners on the successful delivery of 5G and IoT connectivity.


With certification programs continually evolving, (recent new additions include 5G, oneM2M, automotive C-V2X, RSP and mission critical services MCPTT), GCF provides the certainty of reliable mobile data connections that allow organisations to be more competitive.


Products incorporating cellular mobile & IoT connectivity can be certified, such as:

  • 5G devices
  • M2M/IoT products
  • Connected consumer devices
  • Smartphones
  • Feature phones
  • Tablets
  • USB modems
  • Portable WiFi hotspots
  • Embedded modules
  • Laptops

The GCF scheme evolves in sync with developments in mobile technologies and the changing needs of the industry.  GCF is the only wireless product certification scheme that covers all these technologies:

  • 5G
  • NB-IoT, Cat-M1 (LPWA)
  • LTE, LTE-Advanced, LTE-Advanced-Pro (4G)
  • WCDMA (3G)
  • CDMA2000 (3G)
  • GSM (2G)

GCF is a Market Representation Partner of 3GPP and is liaising with standards organisations and industry associations to support the successful development and deployment of 5G.
