Series-level features, frequency bands and optional functions must be confirmed for the exact ordering code and firmware. ## Best for / use cases - **Wearables:** consider BG77 where board area and module weight are key selection factors. - **Asset tracking:** evaluate GNSS positioning and LTE-M coverage on the intended route. - **Smart metering:** validate reporting frequency, network power-saving behavior and battery requirements. - **Wireless POS:** test command response time and operator coverage against the application requirements. ## Key features and benefits - **Small footprint:** 14.9 × 12.9 × 1.7 mm dimensions and 0.73 g module weight support compact designs. - **Dual-mode LPWA:** LTE Cat M1 and Cat NB2 allow selection against available network services. - **Integrated positioning:** GNSS supports location-enabled designs; antenna and application integration remain necessary. - **Hardware-based security:** the source overview describes Cortex A7 TrustZone support for trusted applications. - **Development and maintenance resources:** QuecOpen®, DFOTA and hardware design documentation support integration work. ## Size, fit and design resources Use the 2D/3D dimensions, footprint, hardware design and reference-design resources listed below to check mechanical fit and PCB integration. Match the antenna to the selected cellular bands and, where applicable, GNSS requirements. The [official product page](https://www.quectel.com/product/lte-bg77-cat-m1-nb2/) provides product imagery and the source resource catalog. ## LTE-M vs NB-IoT: which technology fits the application? LTE-M (LTE Cat M1) generally suits moving devices and applications needing more responsive communication. NB-IoT (including LTE Cat NB2) suits small, periodic messages from meters and sensors where the network and application tolerate longer response times. Coverage, roaming and available features depend on the operator and deployment country. | Application requirement | Selection guidance | | --- | --- | | Mobile assets, wearables or responsive commands | Evaluate LTE-M and test mobility and response time on the intended network. | | Fixed meters and periodic environmental readings | Evaluate NB-IoT with representative payloads, reporting intervals and indoor coverage. | | Battery life | Measure the complete device duty cycle, signal conditions and network-granted power-saving settings. | | Remote firmware updates | Validate update size, transfer time, recovery and energy use on the selected mode. | Technology context: [AWS guidance on LTE-M and LPWAN integration](https://docs.aws.amazon.com/whitepapers/latest/implementing-lpwan-solutions-with-aws/lte-m.html). These are technology-level selection guidelines, not measured performance promises for a finished device. ## Compare BG95, BG77 and BC660K-GL | Selection factor | BG95 series | BG77 | BC660K-GL | | --- | --- | --- | --- | | Cellular technology | LTE Cat M1 / Cat NB2 / EGPRS; confirm exact variant | LTE Cat M1 / Cat NB2 | LTE Cat NB2 (NB-IoT) | | Dimensions | 23.6 × 19.9 × 2.2 mm | 14.9 × 12.9 × 1.7 mm | 17.7 × 15.8 × 2.0 mm | | Package | SMT, LGA | SMT, LGA | SMT, LCC | | Main selection reason | Multimode design and migration from existing Quectel families | Compact LTE-M / NB-IoT design with integrated GNSS | NB-IoT design for small, periodic data messages | | Design check | Variant, bands, network modes and migration details | Board space, antenna integration and operator support | NB-IoT coverage, bands and reporting requirements | [BG95 product details](https://www.quectel.com/product/lpwa-bg95-cat-m1-cat-nb2-egprs-series/) · [BG77 product details](https://www.quectel.com/product/lte-bg77-cat-m1-nb2/) · [BC660K-GL product details](https://www.quectel.com/product/lpwa-bc660k-gl-nb2/) Dimensions alone do not establish pin, electrical, firmware or antenna compatibility. Confirm the hardware design and compatible-design documents for the exact ordering code. ## Pricing, supply and project support [Contact Quectel](https://www.quectel.com/contact/) with the product name, deployment country, operator, annual volume and sample requirements to request a quotation and confirm availability. Confirm lead time, delivery, warranty and return terms in the supplier quotation or order agreement. ## Integration, reliability and total cost 1. Match the exact module variant and supported bands to the deployment countries and operators; confirm required approvals for the finished product. 2. Review the footprint, power supply, antenna layout and reference design before committing the PCB. 3. Test registration, reconnect behavior, weak-signal operation and data delivery on the intended network. 4. Measure the energy per reporting cycle and validate power-saving timers against required reachability. A sleeping device may not be immediately reachable. 5. Compare total cost: module, antenna, PCB changes, data plan, certification, firmware maintenance and field service. Low-power operation and reusable design resources can reduce service or development effort when validated in the actual design; savings are not guaranteed.

The Quectel BG77 product overview identifies wireless POS, smart metering, tracking and wearable devices as application areas. Confirm the network, positioning and power requirements of the complete device. ### Does BG77 support both LTE-M and NB-IoT? Yes. BG77 supports LTE Cat M1 and LTE Cat NB2. The usable mode, bands and services depend on the module configuration and local operator. ### How small is the BG77 module? BG77 measures 14.9 × 12.9 × 1.7 mm and weighs 0.73 g, according to the source product summary. Include antenna, power, SIM and clearance requirements when estimating complete PCB size. ### Does BG77 support VoLTE and GNSS? The source page lists integrated GNSS and VoLTE under Cat M1 only. Confirm firmware, operator support and provisioning before specifying voice service; NB-IoT is not a VoLTE mode. ### How should BG77 and BG95 be compared? BG77 has a smaller published package and supports LTE-M/NB-IoT with integrated GNSS. BG95 offers a larger multimode family including EGPRS at the series level. Choose against exact variant, network, footprint and migration requirements rather than dimensions alone. ## Evaluation kits and antennas The related-products catalog below links to evaluation tools and antennas shown on the source product page. Confirm the appropriate evaluation board, module variant, frequency coverage, connector and enclosure requirements with Quectel before ordering. ## Product Brochure Quectel_Product_Brochure_V8.6.pdf [Download](https://www.quectel.com/content/uploads/2026/05/Quectel_Product_Brochure_V8.6.pdf) ## Documentation and resources Some downloads require a Quectel account.
