The average speeds of the five outdoor 4G LTE routers with SIM card slots you are considering generally align with Category 4 LTE standards, offering reliable and stable internet performance suitable for most outdoor applications. Here is a detailed overview based on available data:

Average Speed Overview of the Five Routers

Router Model	LTE Category	Typical Max Download Speed	Typical Max Upload Speed	Notes on Speed Performance
Cat 4 POE 24V/1A Waterproof Outdoor LTE Router with WiFi Extender (HY8172+HY8760)	Cat 4	Up to 150 Mbps	Up to 50 Mbps	Supports multi-band LTE with stable speeds; suitable for streaming, surveillance, and remote work in outdoor environments.
POE 24V/0.5A TR069 Cat 4 Waterproof Outdoor 4G LTE Router (HYQC8300)	Cat 4	Up to 150 Mbps	Up to 50 Mbps	Typical Cat 4 speeds with TR069 remote management; reliable for outdoor use with efficient power delivery.
TR069 Waterproof 300Mbps Outdoor SIM Router (HYQC8301)	Cat 4	Up to 150 Mbps (4G LTE)	Up to 50 Mbps	Advertised as “300Mbps” refers to WiFi throughput; LTE speeds align with Cat 4 standards (150/50 Mbps); stable real-world speeds around 20 Mbps in remote areas reported.
OpenWRT Waterproof 24V/0.5A POE 4G Outdoor Router with SIM Slot (HY8724)	Cat 4	Up to 150 Mbps	Up to 50 Mbps	Cat 4 LTE speeds with OpenWRT flexibility; stable outdoor performance with effective heat dissipation
Cat 4 POE 18V/1A Waterproof 4G Router with SIM Slot (HY85B)	Cat 4	Up to 150 Mbps	Up to 50 Mbps	Standard Cat 4 LTE speeds with waterproof design, suitable for outdoor environments.

The average LTE speeds across these routers are consistent with Cat 4 technology, providing up to 150 Mbps download and 50 Mbps upload in optimal conditions. While the WiFi data rates may be higher (up to 300 Mbps), the cellular connection speed is limited by the LTE category. These speeds are well-suited for outdoor applications such as security cameras, remote work, and general internet access in areas without wired broadband.

If higher speeds are required, consider routers with Cat 6 or above LTE technology, which support carrier aggregation and can deliver faster throughput. However, for reliable and stable outdoor connectivity with SIM card slot routers, these Cat 4 models offer a solid balance of speed, durability, and ease of installation.

FAQ

1. What Are the Benefits of a Router with a SIM Card Slot?

A SIM card router provides 4G/5G LTE internet without relying on wired broadband, making it ideal for:

Remote areas with poor fixed-line coverage
Temporary setups (construction sites, events)
Backup internet for businesses
Outdoor IoT/surveillance systems
It offers portability, easy setup, and often better uptime than traditional connections.

2. How Do I Choose the Best SIM Router for Outdoor Use?

Key features to check:

Waterproof rating (IP65 or higher) for rain/dust resistance
Power over Ethernet (PoE) for easy outdoor installation
4G LTE Category (Cat 4, Cat 6, etc.) – Higher categories = faster speeds
Antenna options (external antennas boost signal in weak areas)
Remote management (TR069) if managing multiple routers

3. Can I Use Any SIM Card in These Routers?

Most unlocked routers support standard nano/micro SIMs from carriers worldwide, but:

Check frequency bands (e.g., B1/B3/B7/B20 for Europe, B2/B4/B12 for the US).
Some carriers restrict SIMs to phones (e.g., AT&T’s “phone-only” plans won’t work).
Prepaid vs. Postpaid: Prepaid SIMs often work best for flexibility.

4. What’s the Difference Between PoE and Non-PoE Routers?

PoE Routers (e.g., 24V/0.5A models) draw power via Ethernet cables, simplifying outdoor setups (no separate power outlet needed).
Non-PoE Routers require a nearby power source.
Tip: PoE is best for surveillance cameras, solar-powered systems, or hard-to-reach locations.

5. How Fast Can a 4G SIM Router Be Compared to Broadband?

Cat 4 routers = Up to 150Mbps (good for HD video/email).
Cat 6/12 routers = 300Mbps+ (better for multiple users/streaming).
Note: Real-world speeds depend on signal strength, carrier congestion, and router placement. For heavy use, prioritize Carrier Aggregation (CA)-enabled routers.
