IN Brief:
- Quectel's EG216Q-GL and BG950Q-GL use Qualcomm technology and retain compatibility with established module footprints.
- The EG216Q-GL supports LTE Cat 1bis at up to 10 Mbps downlink and 5 Mbps uplink, with integrated Wi-Fi scanning.
- The BG950Q-GL supports LTE Cat M1 and Cat NB2 for battery-powered equipment, although migration still requires electrical and software validation.
Quectel Wireless Solutions has introduced two cellular Internet of Things modules that retain established hardware footprints while providing updated communication capabilities for industrial, commercial, and battery-powered connected equipment.
The EG216Q-GL and BG950Q-GL use Qualcomm semiconductor technology and address different cellular requirements. The EG216Q-GL provides LTE Category 1bis connectivity, while the BG950Q-GL supports LTE Category M1 and Category NB2, allowing manufacturers to select between higher data rates and low-power operation.
Announced on 10 November 2026, the modules are intended to support migration from existing Quectel products without requiring an entirely new printed circuit board arrangement. Both are being presented at electronica 2026 in Munich, alongside the manufacturer's broader cellular connectivity portfolio.
Cellular modules integrate the modem, radio-frequency circuitry, and supporting electronics required to connect an embedded product to a mobile network. Their mechanical and electrical characteristics influence power distribution, antenna connections, peripheral interfaces, and the host processor's communication with the modem.
Changing to a module with a different footprint can require alterations to PCB routing, component placement, and the surrounding mechanical design. Established products may also need further qualification when new hardware changes the radio-frequency or electromagnetic characteristics of the completed equipment.
Quectel has retained the mechanical format of existing module families to reduce that work. The approach is particularly relevant to products manufactured over several years, where component availability and changes in cellular network support may require hardware updates without a complete redesign.
The EG216Q-GL uses Quectel's EG2 form factor and measures 29.0 × 32.0 × 2.4 mm. It is intended as a migration option for established modules including the EC2x and EC200A series, EG25-G, EG25-GL, EG21-G, EG21-GL, and UC200A-GL.
The module supports LTE Cat 1bis with maximum specified data rates of 10 Mbps downlink and 5 Mbps uplink. These figures describe the supported cellular transmission category rather than a guaranteed application throughput, which also depends on network loading, signal conditions, protocol overhead, and the connected service.
LTE Cat 1bis uses a single principal receive antenna, reducing the antenna requirement relative to conventional Category 1 implementations employing receive diversity. This can simplify RF routing and enclosure integration in equipment with limited space.
Antenna design remains an important part of integration. Placement, ground-plane geometry, matching components, and surrounding materials influence the usable radio performance, while the cellular bands supported by the module must correspond to those used by the intended mobile network.
The EG216Q-GL also incorporates Wi-Fi scanning, enabling the device to identify nearby wireless access points. Information collected through the scan can support positioning services when satellite navigation is unavailable or unreliable.
Wi-Fi scanning does not independently produce a geographic position. A location estimate requires suitable information about detected access points and an associated positioning method or service, with accuracy depending on the available radio environment.
Quectel identifies commercial telematics, payment terminals, remote monitoring, asset tracking, and smart grid equipment among the applications for the module. These systems often require intermittent data exchanges, remote diagnostics, or the transfer of information collected by sensors and controllers.
The BG950Q-GL addresses equipment with a more restricted energy budget. It supports LTE Cat M1 and Cat NB2, cellular technologies intended for applications where relatively small quantities of information are transmitted and long operating periods may be required between battery replacements.
The module measures 23.6 × 19.9 × 2.2 mm and uses a land grid array package suitable for automated surface-mount assembly. Quectel identifies pin-to-pin compatibility with its BG95, BG950, EG91, EG95, BC35-G, and BC95 R2.0 product families, providing migration options across several established designs.
The newer module's 3GPP Release 14 implementation supports low-power cellular operation and is intended for equipment such as smart meters, asset trackers, safety devices, and wireless payment terminals.
Battery life in these applications depends on much more than the modem's peak transmission current. The duration and frequency of network connections, signal strength, retransmissions, application processing, and time spent in low-power states all contribute to the energy consumed during operation.
Quectel describes the BG950Q-GL as an ultra-low-power design, but has not published an application-independent battery-life improvement against every product that it can replace. Energy savings will need to be established using the intended network conditions and communication workload.
Physical compatibility also does not guarantee complete functional interchangeability. Although a module may fit the existing PCB pads, its supported commands, firmware behaviour, power characteristics, peripheral allocation, and network capabilities may differ from those of the component it replaces.
Migration testing must therefore include the host software and electrical interfaces as well as the mechanical footprint. A change of modem can affect startup behaviour, network registration, communication recovery, and the handling of errors or power interruptions.
Radio approvals also require consideration. Existing equipment certification may not automatically cover a replacement cellular module, particularly where the operating bands, antennas, or radio characteristics change. The applicable assessment will depend on the intended markets and the certification arrangements for the finished product.
Quectel provides reference designs, evaluation hardware, software support, and associated antenna products for the new modules. The company has not disclosed a universal shipping or qualification timetable covering every regional variant and deployment market.
The EG216Q-GL and BG950Q-GL provide different connectivity options while preserving established mechanical interfaces. Their suitability as replacements will depend on whether the selected module satisfies the existing equipment's electrical, firmware, network, and certification requirements without substantial changes to the surrounding design.
