Smart cities need reliable communication for outdoor lighting. But with so many IoT options, which one truly fits? 5G is powerful but costly. NB-IoT is cheap but too limited. LoRa works well locally but lacks global reach.
LTE Cat.1 sits right in the middle. It offers stable coverage, moderate speeds, and cost efficiency. For smart lighting, it’s the “just right” solution—balancing performance, affordability, and scalability.

What Is LTE Cat.1 and Why Does It Matter for IoT?
This cellular IoT standard is built on 4G LTE. Introduced in 3GPP Release 8 in 2008, it targets IoT applications that need moderate data speeds with worldwide coverage.
LTE Cat 1 sits between two extremes. On one side are low-cost, low-speed LPWANs like NB-IoT. On the other side are expensive, high-speed 5G options. Cat 1 delivers dependable mid-range bandwidth. It offers more than NB-IoT’s limited kilobits per second. It avoids the complexity and high costs tied to 5G.
Key technical specifications include:
- 10 Mbps downlink
- 5 Mbps uplink
- Supports Power-Saving Mode (PSM)
- Include extended Discontinuous Reception (eDRX) to conserve battery power
- Voice support via VoLTE
- Low latency—under 100 ms
- Reliable global LTE coverage
Why Is LTE Cat.1 Ideal for Smart Lighting Applications?
Smart lighting needs quick control, real-time status, and occasional updates. It runs on predictable data bursts. It must save power for long-term deployment. It must use secure, widely available networking. LTE Cat.1 delivers on all of these. The table below compares different LTE categories under 4G.
LTE Category | Max Download | Max Upload | Power Efficiency | Typical IoT Use Case |
Cat.0 | 1 Mbps | 1 Mbps | High | Smart meters, sensors |
Cat.1 | 10 Mbps | 5 Mbps | Medium | Smart lighting, POS devices |
Cat.4 | 150 Mbps | 50 Mbps | Low | Mobile routers, cameras |
Cat.6 | 300 Mbps | 50 Mbps | Low | HD video, broadband backup |
How LTE Cat.1 meets smart lighting needs
● Reliable and wide coverage
LTE Cat.1 uses existing 4G LTE networks. It works across cities, highways, and remote areas. This means lighting controllers can connect anywhere there’s 4G without new infrastructure.
● Moderate bandwidth for control and updates
It’s high downlink and uplink speed supports remote dimming through photo controllers and firmware updates. That’s more than NB-IoT or LTE-M, yet far less power-hungry than 5G.
● Power conservation
LTE Cat.1 supports PSM and eDRX. These modes, with the help of photosensors, let lights sleep long and wake just to upload data or receive commands. That cuts power use significantly.
● Secure connectivity
It uses standard cellular encryption and SIM-based authentication. That keeps smart lighting systems shielded from hacking and spoofing.
Smart Lighting Needs vs. LTE Cat.1 Solutions
Smart Lighting Requirement | How LTE Cat.1 Delivers |
Remote control & dimming | 10 Mbps downlink handles commands instantly |
Status monitoring & OTA updates | 5 Mbps uplink supports diagnostics and updates |
Long battery or solar life | PSM and eDRX modes reduce power use |
Wide deployment coverage | Global 4G networks enable plug-and-play rollout |
Data protection & access control | Cellular SIM and encryption ensure security |
How Does Long-Join’s LTE Cat.1 Smart Lighting Controller Series Lead the Market?

The JL-243S-LTE is Long-Join’s LTE Cat.1-based photocell switch for smart lighting. It embeds advanced connectivity, enabling robust and scalable city-wide deployments.
Here are some of its technical highlights:
- Uses a Quectel LTE Cat.1 module for stable cellular data.
- Offers remote switch control, precise brightness adjustment, and fault reporting capabilities.
- Supports GPS for location-aware operations and detects power-off events.
- Streams data to the cloud for real-time feedback and analytics.
The JL-243S-LTE integrates easily with municipal lighting management systems. It relies on standard APIs and SIM-based networking, simplifying deployment and platform integration.
Real-World Deployments
Middle East Smart City – LTE Cat.1 vs. LoRa
In a smart city rollout, LTE Cat.1 was chosen instead of LoRa to avoid building new private networks. Teams valued LTE Cat.1’s use of national 4G infrastructure for fast, long-range connectivity without extra gateways.
Tunnel Lighting in South America – Gateway-Free Setup
In a complex tunnel environment, Long-Join deployed the JL-243S-LTE to deliver node-level lighting control. No central gateway was required. Each controller talked directly over LTE, simplifying installation and reducing latency in command delivery.
China EPC Project – Citywide Monitoring & Energy Saving
Within an EPC (Engineering, Procurement, and Construction) contract in China, Long-Join’s light sensor switches enabled comprehensive lighting monitoring across the city. The LTE Cat.1 connectivity supported real-time power use data, enabling dynamic energy-saving policies via centralized dashboards.
How Does LTE Cat.1 Compare with LoRa, NB-IoT, and 5G?
Technology | LTE Cat.1 | NB-IoT | LoRa | 5G (RedCap) |
Downlink Speed | ~10 Mbps | 26–127 kbps | 0.3–50 kbps | ~100 Mbps+ |
Latency | <100 ms | Hundreds ms–s | Seconds | ~1 ms |
Power Efficiency | Moderate (with PSM) | Very high | Very high | Moderate |
Cost & Complexity | Medium-cost, global 4G | Low module cost/subscription | Low hardware cost, private network | High cost & spectrum need |
Ideal Use Cases | Smart lighting, remote assets, updates | Static sensors, environment monitoring | Campus, agriculture, low-data networks | Video, AR/VR, smart mobility, dense sensors |
Why LTE Cat.1 Is the “Goldilocks” Choice
- NB-IoT is too slow for dynamic control and updates.
- LoRa demands private networks and has limited scalability and data speed.
- 5G offers much more than needed—higher costs and complexity without proportional benefit.
- LTE Cat.1 sits squarely in the sweet spot: fast enough for remote dimming and firmware updates, affordable to deploy, and scalable via existing 4G networks.
Why Should Cities Choose LTE Cat.1 for Outdoor Lighting Control?
There are a number of reasons for cities to opt for LTE Cat.1. Some of these are discussed below:
Solid Reliability on Mature 4G Networks
LTE Cat.1 operates on existing global 4G infrastructure. That means deployments don’t need new network build-outs or proprietary gateways. Reliability stems from widespread coverage wherever LTE exists.
Plug-and-Play Compatibility via SIM Cards
Deployment is seamless. Smart outdoor LED lighting controllers just need standard IoT SIMs to connect. No custom network rollout, just install and go.
Sufficient Bandwidth Without Overspending
With good downlink and uplink, LTE Cat.1 handles remote dimming and firmware-over-the-air updates. It delivers exactly what’s needed.
Secure Authentication and Encryption
LTE Cat.1 uses SIM-based authentication and cellular-grade encryption. That delivers trusted, secure communication for public infrastructure.
Scalable Without New Infrastructure Costs
Because LTE Cat.1 reuses existing LTE networks, expanding citywide lighting systems incurs no new network infrastructure expenses. It’s scalable by simply adding devices to the cellular grid.
What Does LTE Cat.1 Mean for the Future of Smart Cities?

LTE Cat.1 stands firm as a dependable IoT backbone well into the future. According to Berg Insight, it is forecast to be the most widely used cellular IoT technology by 2028 (excluding China). The newer LTE Cat.1 bis is gaining rapid adoption. It is expected to displace nearly 70% of standard Cat.1 modules by 2029.
LTE Cat.1 and Cat.1 bis together form a connectivity solution that is:
- Durable—supported by network stability and long-term module forecasts.
- Energy-smart—via power-saving modes and simpler hardware.
- Scalable—deployable using existing infrastructure with easy upgrades ahead.
In essence, LTE Cat.1 serves as the “Goldilocks” IoT connectivity choice—not too weak, not too complex—perfectly aligned with the evolving needs of smart cities.
