300m’s mission is to radically accelerate accessibility to ultra-cheap and light-speed (literally) data transfer and mobile communications for everyone, everywhere.

What’s the Problem?

Access to the Internet

By the end of 2019, it’s projected that approximately 3.5 billion people worldwide will have access to the internet.

The lifeblood of nations’ economic prosperity, the platform for enhanced human interaction and development, will only reach half of the denizens of our world.

While that number is closer to 80% for developed nations, it’s astonishing to think ~4 billion people won’t have access to the medium that has jumpstarted businesses, industries and movements.

Arguably, people without internet, are people, who frankly, don’t actively live in the present.

Now, granted, some of those people choose to stay disconnected from the rest of the world, and that’s totally fine. To be precise, 0.003% of that 4 billion (relatively) isolated individuals comes to about 120 000 souls. AKA, a very small amount.

The rest of them, want to connect with friends on Facebook, want to sell on Etsy, want to accept payments via Square: they want the tools to advance not just their economic situation, but also their emotional one.

Increased Data Traffic

By 2019, all the people who do get on the internet will cause a 24% increase in global internet traffic.

That’s 24% more data being transferred, more information being processed and more Netflix being streamed.

Beams of Light that Empower Billions

Fibre optic infrastructure can support this spike in demand, but the logistics of implementing such a network prove time-consuming and costly, especially given the rough terrain and other physical barriers that make expansion impractical.

Because of this, mobile internet capabilities in developing and treacherous nations are drastically lower and often non-existent.

Interestingly India, China and African and South American countries (regions with the greatest populations) are those with the lowest percentage of citizens with access to the internet.

Free Space Optical Communications (FSOC) is a radical new technology that allows for data transfer. Similar to fibre optics, but without the wires, FSOC uses a system of receivers and emitters (devices that look like movie cameras places at elevated locations like poles or rooves of buildings) to send pulses of light through the open-air of internet data (anything from voice to video) across 10s of kilometres while delivering upwards of 10 Gbps of speed.

Fibre optics operate based on wavelength division multiplexing (WDM) technology that is capable of facilitating fast and long-range data transfer for thousands of people at a time.

WDM means propagating light at different wavelengths (different signals and data) simultaneously through the same medium (conventionally wires, but for our case, laser receiver/emitters) while maintaining the quality of each signal.

how wavelength division multiplexing works

You can do this if there’s a gap between each wavelength that’s enough to separate pulses and prevent interference: as small as a tenth of a nanometer.

WDM systems use couplers to group signals together. On one end, a multiplexer puts light sources together and a demultiplexer divides one light source into many which radically increases the system’s data transmission capability.

It just so happens that instead of sending this single light pulse through a wire, we’re sending it through open air. Receivers and emitters on each side then funnel our light signal into a multiplexer or demultiplexer to recognize individual signals and push them into existing router and cell service networks.

300m: a revolutionary telecom venture

Here at 300m, our mission is to radically accelerate accessibility to ultra-cheap and light-speed (literally) data transfer and mobile communications for everyone, everywhere, because we know, the internet is the single most important factor in empowering individuals to transform their lives economically and emotionally.

At 300m, we strive towards a world where 100% of people who want access to the internet, can have it, for an extremely low-cost, at ultra-high speeds.

300m is developing a network of FSOC receivers and emitters hosted in strategic geographic locations in developing regions to facilitate an extremely capable mobile communications network for locals while leapfrogging the mass network infrastructure that developed nations struggle to deal with.
