Piston Labs Network Technology

Last Updated: 2026-01-02
Purpose: Investor/sales reference for connectivity strategy


Executive Summary

Piston Labs uses LTE Cat-M1 devices with Soracom multi-carrier SIMs to ensure 10+ year device lifespan and carrier-agnostic connectivity. This avoids the mass hardware recalls that competitors faced during 2G/3G network shutdowns.


The Problem with 2G/3G

NetworkStatusImpact
2G (GSM/GPRS)Shutdown complete in US (AT&T 2017, T-Mobile 2024)Dead
3G (UMTS/HSPA)Shutdown complete in US (all carriers by Feb 2024)Dead
Legacy devicesBouncie, older fleet trackers, cheap OBD donglesBricked

Millions of connected car devices became e-waste when carriers shut down 2G/3G networks. Companies like Bouncie had to execute mass hardware replacements, causing customer churn and significant costs.


Our Solution: Teltonika FMM00A

The Teltonika FMM00A is a professional-grade OBD-II telematics device with future-proof connectivity.

Why LTE Cat-M1?


Our Solution: Soracom Connectivity

Soracom provides carrier-agnostic global IoT connectivity with pay-as-you-go pricing.

Traditional vs Soracom Approach

Traditional ApproachSoracom Approach
Locked to one carrier (AT&T/Verizon SIM)Multi-carrier SIM - roams across networks
Carrier sunsets network → device diesAuto-switches to available network
US-only or complex roaming dealsGlobal coverage - same SIM works in 130+ countries
Contract minimums, overage feesPay-as-you-go - $0.06/day + data used
Manage carrier relationshipsSingle dashboard, API-first

Network Fallback Chain

Primary:    T-Mobile LTE Cat-M1
    ↓ (no signal)
Fallback 1: AT&T LTE Cat-M1
    ↓ (no signal)
Fallback 2: NB-IoT
    ↓ (international)
Fallback 3: 2G roaming (EU, LatAm where available)

Soracom Beam: Protocol Conversion

Our devices send raw TCP to Soracom Beam, which converts to HTTPS before hitting our Cloudflare Workers:

Teltonika Device → TCP → Soracom Beam → HTTPS → Cloudflare Workers

Why This Matters to Investors

1. No Mass Hardware Recalls

2. Lower Churn

3. Global Expansion Ready

4. Carrier Negotiation Leverage

5. Predictable Unit Economics


Why This Matters to Customers

Consumer Messaging

ConcernOur Answer
"Will this work in 5 years?"Yes - LTE-M has 10+ year runway, backed by carrier investments
"My last tracker stopped working"Ours won't - built on IoT-specific LTE, not legacy networks
"What about dead zones?"Multi-carrier fallback finds the best signal automatically

Fleet Messaging

ConcernOur Answer
"We have trucks across the US and Canada"Same device, same SIM, automatic roaming
"What if one carrier has an outage?"Auto-switches to alternate carrier
"We got burned by 3G shutdown"LTE Cat-M1 is the new long-term standard
"Hidden fees?"Pay-as-you-go, ~$1.92/device/month all-in

Network Lifespan Projections

TechnologyExpected SunsetOur Exposure
2G GSMComplete (US)None (fallback only for international)
3G UMTSComplete (US)None
4G LTE2035+Low (Cat-M1 is subset, will outlast voice LTE)
LTE Cat-M12040+Primary - carriers actively expanding
5G NRN/AFuture upgrade path, same Soracom SIM

Bottom line: Our devices have a 10-15 year connectivity runway before any network concerns.
