Charter let the world know that it plans to pursue RDOF grant funding in its most recent 8-K filing with the Securities and Exchange Commission. The company says that it might pursue grant funding to build to ‘multi-million passings’ involving ‘multi-billion investments’. It’s an interesting strategy. Charter already serves rural county seats and other towns across the country which puts them close to many of the areas where RDOF funding is available.
The RDOF grants cover the most rural and remote pockets of customers in the country. While there are some small rural towns included in the RDOF grant footprint, most of the customers covered by the grants are truly rural, consisting of farms and scattered homes in rural counties.
Charter will have to make some technology choices about how to serve rural America. The company can win the most money in the grant process if they file as a gigabit-speed provider. Gigabit speeds are available today with fiber technology and also with the hybrid fiber-coaxial networks operated by Charter and other cable companies. The RDOF grants can be awarded to technologies that support speeds over 25/3 Mbps. However, the grant includes incentives to favor ISPs willing to use faster technologies.
Charter could pursue slower technologies, like fixed wireless, but that funding is harder to win. To date, none of the big cable companies have ventured into wireless technology, other than a few trials. It’s always been a bit of a mystery why Charter and other cable companies haven’t erected wireless antennae at the fringes of their network to cheaply capture customers just out of reach of the HFC networks. My theory has always been that big cable companies are not nimble enough to handle drastically different technology platforms since all of their processes are designed for around coaxial and fiber technologies.
Charter is likely considering building fiber-to-the-home networks if they win RDOF grant funding. The hybrid fiber-coaxial technology that cable companies use in urban areas is poorly suited to serving scattered rural customers. The signal on an HFC network has to be boosted every two miles or so, and every time the signal is amplified some of the effective bandwidth carried on the network is lost. It would be a major challenge to maintain gigabit speeds required by the grants on a rural HFC network. It would only be possible with lots of fiber and tiny neighborhood nodes serving only a few homes. Charter has often cited the technology challenges of uses HFC technology in low-density areas as the reason it doesn’t expand outward from existing markets – and those reasons still hold true.
Charter claims to have expanded to add 1.5 million homes to its existing networks over the last two years, and in the 8-K filing says these are mostly rural customers. However, from what I’ve heard, most of these new Charter neighborhoods are in small subdivisions surrounding existing Charter markets. Charter has not been building rural networks to reach 1.5 million farms.
Charter and the other big cable companies have quietly introduced last-mile fiber technology into their networks. When cable companies build into new subdivisions today, they mostly do so with fiber technology.
It would be interesting if Charter’s strategy is to use the grant money to build fiber to farms. I know plenty of other ISPs considering the same business plan in places where there is enough RDOF grant funding available to make a business case.
There is no guarantee that Charter will ultimately win any grant funding and filing the grant short form on July 15 only gives Charter the option to participate in the auction in October. However, if the company bids in the auction, it will be good news for markets where Charter would build fiber technology. The big downside to the RDOF grant process is that in markets where no ISPs propose to build gigabit technology, the funding could end up going to satellite broadband providers – and there is no rural neighborhood that would prefer Viasat over Charter.
