Aren’t we glad that Russia doesn’t target civilians? This is pure terrorism.

The basic idea here is that the BitChat application on smartphones faces limitations due to the restricted range of Bluetooth, which is optimized to save battery life. For mesh networking, you want to maximize the transmission and reception range. This can be achieved by enhancing the power supply, using better antennas, and other improvements. Once people understand the benefits, there will be an incentive to develop custom hardware that performs better than a standard smartphone for this purpose. The technical details are useful for those with a more technical background, but that's the main point.

Good question — Bluetooth range can be extended well beyond typical consumer expectations with custom hardware, antennas, and power configurations. Let’s break it down:

---

## 📡 Theoretical Bluetooth Range by Class

| **Bluetooth Class** | **Power Output** | **Typical Range (Indoor)** | **Max Range (Ideal Conditions)** |

| ------------------- | ---------------- | -------------------------- | -------------------------------- |

| Class 3 | 1 mW | \~1 meter | \~10 meters |

| Class 2 | 2.5 mW | \~10 meters | \~50 meters |

| Class 1 | 100 mW | \~100 meters | **\~300–1000+ meters** |

> 🔧 Most phones are Class 2 or 3. Custom setups can use **Class 1 modules** with high-gain antennas.

---

## 🛠️ Custom Hardware Range Expansion

With modifications:

### ✅ 1. **High-Gain Directional Antennas**

* Patch, Yagi, or parabolic grid antennas can focus the Bluetooth beam

* Range can exceed **1 km line-of-sight**

* Example: Point-to-point modules like **UBlox**, **Roving Networks RN-41**, or **ESP32 + u.FL connector**

### ✅ 2. **External Power Amplifiers**

* Legally limited in some countries, but boosts effective radiated power (ERP)

* Can push practical Bluetooth LE range to **2–4 km** in optimal rural or elevated conditions

### ✅ 3. **Class 1 Bluetooth Modules**

* Some dev boards (like Nordic nRF52840) can operate with 100 mW output

* Paired with low-noise amplifiers (LNA) and external antennas

---

## 🌍 Real-World Extended Bluetooth Examples

* **Mesh relay hopping** (like in Bitchat): with 100–300 m per hop, a mesh of 10–20 devices could stretch coverage **several kilometers**

* **ESP32 BLE + Directional Antenna**: users have achieved **1–2 km** LOS range using patch or biquad antennas

* **LoRa-BLE hybrids**: while not true Bluetooth, some boards emulate BLE over long-range modulation for **10+ km**

---

## ⚠️ Legal + Practical Notes

* Regulatory bodies (like the FCC/CE) limit ERP for 2.4 GHz

* Using **external antennas or PA/LNA modules** may violate consumer device certifications

* More power means more interference and power draw — not ideal for mobile mesh unless nodes are solar or mains powered

---

## 🧠 Bottom Line

With proper setup:

* **Class 1 + directional antenna** = up to **1 km LOS**

* **Mesh relaying** = easily 3–10 km range across nodes

* **BLE 5.0 Long Range (coded PHY)** = native support for **several hundred meters** with compatible devices

I was just thinking today: wen are all these bitchat users gonna hit nostr relays

Out here walking around with Bitchat open like I’m hunting Pokémons

Wild how much a quick workout can change your brain

I visited the Finnish Bitcoin Association yesterday, these Finns are not playing. 💪🏻

Mining sats with negative rate energy, teaching kids to build btc atms and automated m&m sales with lightning invoice triggered dispensers.

This is what its about for me, and Jack was really impressed.

Wonderful day, peaceful. Nostr is chill and filled with cool friends.

The moment I check twitter I'm pissed off.

Nostr only soon, when I'm done being passed off.

I don’t think I’ve ever been anywhere where I enter a space and people are coming at me “give us a way for us to pay you!!”

The ethos here is really incredible. Already feeling totally supported.

Blacks are violent and dangerous.

We’ve always known this.

Separate but equal wasn’t out of hate, it was out of necessity.

What’s sad is that most whites shrug instead of saying we must return to segregation.

Stay away from blacks

A golden hour paddle..

I’m treasuring these longer nights and beautiful sunsets! ✨

Could you tell me what experience have you had that you think Carnival is low budget?

NOICE Visual Expression Awards submission by Alex Sheffield:

"The lost art of discomfort, the true form of one’s self. These images put forth a notion that when lost and alone, colors and strangers will more often than not be kind to you when they see you taking a path less traveled, a journey less blind to traditions and expectations. The images frame themselves when your busy mind is quiet and loves being alone. I have had moments and years where I feel lost, but looking past my eyes, I sense the beating heart of humans and cities, all in a harmony of entropy and imperfect balance. This brings me endless comfort. I enjoy feeling small, like a speck of sand on a mile long beach."

GM ☀️☕️ Happy Fiat-Mining Monday

GM2! Love the silence.

Cool we now got, mechanics, janitor and technicians. What else we need? Scientists?

I agree. Funny that this blackman is piggybacking off of a white man's efforts to record this.

sometimes you do just have to sing it out and then it all makes so much more sense right
