The
Markup

Two public awards fix the price of a military mesh radio. In 2017 the United States Army National Guard paid Persistent Systems $8.9 million for more than 950 MPU5 radios. That is under $9,400 each. In February 2024 the Air Force paid $5.1 million for more than 280 MPU5 radios and ten sector antennas. That is at most $18,214 each, and the antennas are inside the number.

The vendor of the Haven build guide says the class of capability costs twenty thousand a unit. The public record does not say twenty. It says between nine and eighteen, and the newer award is the higher one.

The Haven node is a Raspberry Pi 5, a Morse Micro HaLow radio, an antenna, a battery hat and a printed enclosure. The guide prices the build at $208 to $450 per node. A network needs two. The guide itself is $97, and the parts list, firmware and configuration are on GitHub without it.

Two nodes, four hundred and sixteen dollars at the floor. One government radio, eighteen thousand two hundred at the ceiling. The ratio is forty-four to one against a single node, and the comparison is not fair. What follows is where the unfairness lives.

The chip is legal to run in Canada because of a document called RSS-247. Issue 4 was published by Innovation, Science and Economic Development Canada on 24 July 2025 and became mandatory on 24 January 2026. For digital transmission systems in the band 902 to 928 MHz it sets a peak conducted power of one watt, an e.i.r.p. of four watts, a minimum bandwidth of 500 kHz and a spectral density of 8 dBm in any 3 kHz. No licence. No fee. No application. Point-to-point links may run higher e.i.r.p. under the same document.

Twenty-six megahertz of clean sub-gigahertz spectrum, open to anyone, shared with the United States under an almost identical rule. That is the widest public allocation of its kind on earth.

Europe's equivalent sits at 863 to 868 MHz. Five megahertz wide, a fifth of the North American band, and most of it capped at 25 milliwatts. A HaLow mesh that reaches kilometres in Langford reaches a few hundred metres in Lyon, not because the chip changed but because the law did.

The band is also the first honest entry in the ledger against the four-hundred-dollar node. A government radio does not live at 902 MHz. It lives in licensed bands, C-band 4,400 to 5,000 MHz among them, where it may run multiple watts and shares the spectrum with nobody. One watt in a band full of baby monitors and LoRa is the price of admission to the public. The contractor's customer never paid it.

Above the chip there is no hardware, and above the chip is where the money is.

The mesh is 802.11s, the mesh mode written into the Wi-Fi standard itself, carried by BATMAN-adv, a Layer 2 routing protocol that lives inside the Linux kernel and reroutes around a dead node without being told to. The operating system is OpenWrt. The remote management is WireGuard. Every one of these is free software with a decade or more of hostile use behind it.

On top of that sits Reticulum. Written by Mark Qvist, release 1.5.3 in September 2026. It is not an application. It is a second network stack that does not need IP. Every node is a 512-bit elliptic-curve identity. Every packet is X25519 encrypted and Ed25519 signed, with ephemeral Curve25519 keys for forward secrecy, AES-256 in CBC mode and HMAC-SHA256. Packets carry no source address. It runs over anything faster than five bits per second with a 500-byte MTU: LoRa, packet radio, a serial line, HaLow. Bridge a LoRa board to the Pi and the same identity is reachable over both radios.

Here is the thing the $18,214 pays for, stated by the vendor. Up to two layers of FIPS-compliant, NIAP-approved, CSfC-approved encryption. Read the adjectives. Compliant. Approved. Approved. None of them is a cipher. AES-256 on a certified module is the same mathematics as AES-256 in OpenSSL. What FIPS 140 buys is a validated implementation and a document that says so, and the document is what a procurement officer is allowed to sign.

The waveform is different. Persistent's Wave Relay and Silvus's MN-MIMO are proprietary 3-by-3 and 2-by-2 MIMO schemes with RF signature management, low probability of intercept and detection, and a Department of Defense assessed library of electronic-attack fingerprints and countermeasures. That is real engineering and Haven has none of it. Against a peer adversary running a jammer, the Pi loses. Against everyone else on the planet, the jammer never arrives.

Edition 02 asked of a graphics card whether the silicon underneath still worked. The test for a radio is different because the silicon was never withheld. Morse Micro will sell the chip to anyone. The test is what the buyer is paying to be.

A capability price pays for something the cheaper product cannot do at any cost. The licensed band is one. The anti-jam waveform is another. If your adversary has an electronic-warfare unit, the eighteen thousand is not a markup. It is the product.

A customer price pays for the buyer's own constraints. FIPS validation exists because federal purchasers may not buy unvalidated cryptography, not because AES needs a certificate to work. MIL-STD-810G exists because a program office must prove it tested for salt fog. NDAA compliance exists because Congress said so. The radio did not need any of these to route a packet. The buyer needed them to write the cheque.

Most of the world is not a federal purchaser and is not being jammed by a state. A rural property in British Columbia. A film crew. A mine. A farm. A municipality that lost its fibre. A protest. A wildfire perimeter after the towers burn. For all of them the physics rows of the ledger read the same and the paperwork rows read zero.

That is the markup. Not fraud, not even a bad product. Persistent Systems and Silvus build serious radios for a customer who genuinely needs the top two rows. The markup is what everyone else pays if they buy the same product, and until 2025 there was no other product to buy. There was no 256-QAM sub-gigahertz chip on the open market. There was no 43-megabit HaLow module with the filter already on it. Now there is, and the parts list is public.

The question is no longer whether the capability can be had for four hundred dollars. It can. The question is which customers still need the other seventeen thousand, and the answer is a shorter list every year.
