MeshCore Tulsa — Communication Without Internet

Build Alongside Your Neighbors: MeshCore Mesh Network in Tulsa

In May 2019, the Arkansas River unleashed catastrophic flooding across the Tulsa metro, inundating neighborhoods, threatening the levee system, and forcing widespread evacuations. Tornadoes strike Oklahoma more frequently than nearly anywhere on Earth — Tulsa sits in the heart of Tornado Alley. Community members across Tulsa are now building a MeshCore mesh network — small radio devices that let you send messages without internet, without cell towers, without any infrastructure. Just people and radios.

Tulsa's Grassroots Answer to Communication Fragility

Tulsa sits at the Arkansas River crossroads of Tornado Alley, where geography and severe weather have shaped the city's identity for over a century. The May 2019 Arkansas River flooding was the worst in decades — releasing record volumes from Keystone Dam, threatening to overtop the city's levee system, and forcing evacuations from West Tulsa through Sand Springs. Powerful tornadoes have raked the metro repeatedly — including the deadly 1970 Lubbock-area tornadoes and more recent outbreaks that struck Broken Arrow, Owasso, and surrounding communities. Ice storms bring down power lines across the region nearly every winter, leaving neighborhoods from Bixby to Sapulpa isolated for days.

That's why community members are building a MeshCore mesh network — an independent emergency communication layer that doesn't depend on cell towers, internet, or the power grid. Each small radio device communicates directly with nearby devices using LoRa signals. Messages hop from device to device across the metro. The more Tulsa-area residents who join — from Jenks to Owasso, from Broken Arrow to Claremore — the stronger this community safety net becomes.

Why Tulsa's Communication Network Has a Single Point of Failure

Tornado Alley Puts Tulsa in the Crosshairs Every Spring

Oklahoma ranks first in the nation for tornadoes per square mile, and Tulsa sits near the center of the most active zone. Severe thunderstorms with large hail, damaging winds, and violent tornadoes are a near-certainty from April through June. When a tornado touches down in Broken Arrow, Owasso, or Catoosa, cell towers are among the first structures to fail — and the overloaded networks that survive can't handle hundreds of thousands of people trying to reach loved ones simultaneously. A community-built MeshCore mesh network with battery-powered nodes is designed to keep neighborhood communication alive when severe weather knocks out traditional infrastructure.

Arkansas River Flooding Threatens the Western Metro

The 2019 Arkansas River flooding proved that catastrophic flooding isn't hypothetical in Tulsa — it's recent history. Water released from Keystone Dam overwhelmed the Arkansas River channel, threatening the levee system protecting West Tulsa and Sand Springs. Thousands evacuated as floodwaters rose. Roads were impassable, and cell service failed across wide areas of the flood zone. A MeshCore mesh network creates communication paths that don't depend on bridges, roads, or riverside cell towers — letting residents on both sides of the Arkansas stay connected when floodwaters rise.

Ice Storms Isolate Neighborhoods for Days

Oklahoma ice storms bring freezing rain that coats power lines and trees, causing widespread outages that can last for days or even weeks across the metro. Neighborhoods from Bixby to Sapulpa can lose electricity and heating while utility crews struggle to restore power. When the power goes out, cell towers lose backup battery power within hours, and landlines connected to internet-based phone systems go silent. A MeshCore device runs on a small battery that lasts for days and communicates by radio — no grid power, no internet, no cell towers needed to check on neighbors and coordinate during prolonged ice storms.

Rolling Terrain and Elevation Are Ideal for Long-Range Radio

Tulsa's geography is actually a major advantage for mesh networking. The city sits on rolling hills and bluffs overlooking the Arkansas River, with elevation changes that provide natural vantage points for radio signals. A single repeater mounted on a hilltop or tall building in Midtown can have line-of-sight coverage spanning miles in every direction — from Downtown across the river to West Tulsa, south toward Jenks, east to Broken Arrow, and north to Owasso. The rolling terrain that defines Tulsa's landscape also makes it one of the best cities in Oklahoma for building a long-range mesh network.

How MeshCore Spans the Tulsa Metro

MeshCore uses LoRa (Long Range) radio technology to send encrypted messages between small, affordable devices. Each device acts as both a communicator and a relay — passing messages along to nearby devices. No Wi-Fi, no cellular, no internet required. A device in Brookside can relay a message from Cherry Street to Riverside through a chain of community nodes.

Repeaters placed on rooftops and elevated structures dramatically extend range across Tulsa's rolling hills. A single solar-powered repeater on a hilltop in South Tulsa can bridge from Downtown to Jenks and beyond. Community members build this network together — each new device strengthens coverage for everyone. It's useful every day for private, off-grid communication — and critical when tornadoes, river flooding, or ice storms knock out traditional networks.

Neighborhoods Building the Tulsa MeshCore Network

Downtown & Midtown

Tulsa's urban core along the Arkansas River provides the best elevated positions for mesh nodes in the metro. Repeaters on Downtown high-rises and the BOK Tower have line-of-sight across the river to West Tulsa, south through Midtown to Brookside, and east toward Cherry Street and Utica Square. These central nodes form the backbone connecting the sprawling southern and eastern suburbs to the western communities along the Arkansas River.

Broken Arrow & East Metro

Broken Arrow is Oklahoma's fourth-largest city and has experienced its share of severe weather, including damaging tornadoes and ice storms. Mesh nodes in Broken Arrow and the surrounding Bixby and Coweta communities create critical eastern coverage, linking these fast-growing suburbs through South Tulsa back to the Tulsa core network. Families in this sprawling suburban area benefit from an independent communication channel that works regardless of infrastructure conditions.

Owasso & North Metro

Tulsa's northern suburbs stretch from Owasso through Collinsville toward Claremore, where new neighborhoods push into rolling prairie. This suburban sprawl means families often live 15 to 20 miles from the city center. The rolling terrain is ideal for LoRa signals — devices here benefit from elevation advantages and clear line-of-sight paths. Mesh nodes in Owasso and Catoosa fill the critical gap between the urban core and the northern reaches of the metro.

West Tulsa & Sand Springs

West Tulsa sits on the opposite bank of the Arkansas River from Downtown, making this area uniquely vulnerable during flooding events. When the 2019 flooding threatened the levee system and closed river crossings, residents on the west bank lost contact with the rest of the metro. Mesh nodes in West Tulsa and Sand Springs create relay paths that don't depend on bridge crossings or riverside cell towers — keeping both sides of the Arkansas River connected through any disaster.

MeshCore in Tulsa: Uses That Matter

  • Tornado warning coordination: When severe storms roll across Oklahoma and tornado sirens sound, your MeshCore device keeps you connected to family and neighbors even as cell networks overload. Share ground-truth storm conditions, confirm family members reached shelter, and coordinate neighborhood response — no cell service needed.

  • Arkansas River flood monitoring: During spring flooding season, share real-time water levels and levee conditions with neighbors across the metro. When the Arkansas rises faster than official alerts can track, mesh-connected residents from West Tulsa to Jenks provide critical ground-level information to their community.

  • Ice storm neighborhood check-ins: Oklahoma ice storms can isolate elderly neighbors and families without backup heating for days. Use your MeshCore device to check on vulnerable neighbors along your street, coordinate tree removal help, and share warming shelter locations — even when power and cell service are down across the metro.

  • Daily off-grid communication across the metro: End-to-end encrypted MeshCore messages hop across community nodes spanning the entire metro — from Owasso to Jenks, from Sand Springs to Broken Arrow. Private messaging that doesn't depend on any corporate network, ISP, or cell carrier. Useful for events at ONEOK Field, the Tulsa State Fair, or simply staying in touch across town.
