4G Smartwatch Offerings

Re-evaluating Our 4G Smartwatch Offerings

While the previous sections highlighted the numerous advantages and impressive features of 4G smartwatches, it's crucial for us to present a holistic view. At iSmarch, we believe in complete transparency with our customers, which includes discussing not only the benefits but also the challenges faced with certain products. Here's a more in-depth look into the complexities associated with 4G smartwatches in the IoT industry:

Challenges with 4G Smartwatches in IoT Industry:

  • Persistent Network Issues: Users frequently encountered inconsistent network performances which affected the smartwatch's primary functionalities.
  • Carrier Strategy Restrictions: Limitations and policies imposed by carriers often hindered the device's full potential.
  • Elevated SIM Card Costs: Users were often confronted with high tariffs for SIM cards, making the product less cost-effective.
  • Recurring Costs: The periodic renewal fees for SIM cards added a recurring expenditure for the users.
  • Constant Adjustments: Regular updates in terminal interaction protocols and carrier strategies demanded continual adjustments, complicating the user experience.
  • Third-party Recharge Platforms: Strategy alterations from third-party recharge operation platforms further complicated the connectivity process.
  • Software Platform Complexities: Customers faced intricacies with their software platform, especially concerning its development capabilities, stages, and redundancies.

While our 4G smartwatches shone during the initial "Proof Of Concept" (POC) stage, many customers reported operational challenges post-POC, especially with cellular operators.

Our Recommendations for a Seamless Experience:

Understanding CATM vs. CAT1: Before diving into recommendations, it's vital to distinguish between CATM and CAT1. CAT1, designed for applications that require medium to high data rates like wearables and smart meters, has been the traditional choice for IoT devices requiring cellular connectivity. In contrast, CATM (or LTE-M) is a newer standard optimized specifically for the broader needs of IoT devices. It offers extended coverage, longer battery life, and better building penetration, making it ideal for IoT applications where devices might be located in challenging environments.

Considering CATM or NB IoT Smartwatches: If your operations can navigate the challenges associated with 4G smartwatches, we suggest exploring our CATM or NB IoT smartwatches. These devices are designed with the IoT industry in mind, offering better efficiency, connectivity, and tailored features for industrial applications.

Optimized Energy Consumption: One primary concern with 4G and similar cellular connectivity is their high-power consumption. Bluetooth gateway, LoRa gateway, or similar products offer a more energy-efficient solution.

Progressive Clientele Strategy: Our most successful customers often follow a phased approach:

  • Address safety concerns, especially those related to data transmission and communication.
  • Manage and present health data to elevate its value.
  • Delve into data mining to generate actionable prescriptions.
  • Provide services based on these insights, ensuring a comprehensive solution.

The Superiority of Bluetooth or LoRa: For long-term value and reliability, we suggest our Bluetooth or LoRa series products. These provide precise PPG data and other critical metrics like Heart Rate, SPO2, HRV, and Sleep patterns—indispensable for sectors like healthcare.

The Way Forward: While core functions like two-way communication via 4G are beneficial initially, it's crucial to add value through accurate vital sign readings. This insight is based on extensive experience and feedback from numerous customers. We recommend transitioning from 4G to methods like Bluetooth to BLE gateway to server or the built-in Bluetooth with LoRa to LoRa Gateway to server for optimal results.
