Compare X55 and X62 5G Modems
X55 and X62 are two generations of Qualcomm’s Snapdragon 5G modem platforms. They are widely used in smartphones and 5G cellular routers. They both support the latest 5G-NR cellular networks, transceiving data over Sub-6 GHz spectrum bands, and connecting to cell towers in SA (standalone) and NSA (non-standalone) modes.
X62 is the newer generation than X55, but does that make it the better choice for every 5G router?
The comparisons between X55 and X62 below are based on actual modem modules used in OutdoorRouter products, not only the theoretical capabilities of Snapdragon platforms. The X55 modems are based on SIMCom SIM8202G, while X62 routers use the Quectel RM520N. Each 5G modem module may have variations even within the same generation.
The speed rates listed below are theoretical maximum modem capacities. The connection speed in practical applications usually varies with signal quality, congestion, available bands, your data plan, and your carrier’s throttling policy.

The Key Difference: 3GPP Release 15 vs Release 16
The 3GPP standards are global technical specifications that define the operation of 5G networks. Release 15 represents 5G Phase 1, laying the foundation for consumer 5G, while Release 16 represents 5G Phase 2 and enhances network hardening, efficiency, and service expansion.
The X55 module is based on 3GPP Release 15, while the X62 RM520N is based on Release 16. Benefiting from a newer generation, the X62 5G modem offers a bundle of advanced features (briefed below) with enhanced 5G connectivity and improved data speeds.
Carrier Aggregation Combos
Compared to the X55 modem, which combines low and high frequency pairing, the X62 modem can utilize more bands and supports a wider range of intelligent carrier aggregation combinations. It helps the X62 modem combine multiple low-band and mid-band carrier aggregations to deliver greater bandwidth and faster speeds, especially in areas with weak signals or in rural locations.
5G and LTE Speed Rates
As a result of the above-mentioned 3GPP release standards and carrier aggregation combos, the most obvious and intuitive difference between X55 and X62 modems is internet connection speed. The X55 module supports up to 2.4 Gbps 5G download speeds, with LTE connectivity that falls back to Cat 16 at up to 1.0 Gbps. The X62 modem offers up to 3.4 Gbps and supports LTE Cat 19 with up to 1.6 Gbps.
X55 or X62 Modems: Which is Better?
Neither modem is the best choice for every deployment. The X55 modem is the value option for mainstream 5G applications, while the X62 modem offers enhanced performance for users looking for greater cellular performance. You can find more relevant suggestions for suitable use cases below.
When Should You Choose X55?
Choose an X55 5G router for dependable 5G connectivity at a lower cost. X55 is a practical choice when mainstream 5G performance is enough, and you do not need the extra headroom of a newer modem platform. It is well suited to:
> Home and small-business broadband,
> Backup Internet, Remote monitoring, and
> Standard industrial and M2M applications.
When Should You Choose X62?
Choose an X62 5G router if you have enough budget and need a more future-proof router. X62 is a stronger choice to provide enhanced 5G cellular performance for more demanding deployments, such as:
> Higher-throughput mobile broadband,
> Business and industrial networks, and
> More demanding M2M deployments.
In some cases, upgrading from X55 to X62 may not significantly increase cellular internet speeds, as these are affected by various factors, including carrier capacity, available spectrum, and signal conditions. The optimal choice also depends on the overall router setup and other hardware features.
