Points to Ponder

All Local Loops Are Local

15% of Cost of a Broadband Network Goes to Technology

“Over Builds” are “Greenfields”


What is Broadband?

It’s not about bitrates or technologies

25 Mbit/s down, 3 Mbit/s up - FCC, 2015[20]

10/1 for rural

➢ 4 Mbit/s down, 1 Mbit/s up - FCC, 2010[20

It’s critical infrastructure for community survival

Rural Broadband isn’t broken, it’s never been fixed

Community Reality

There is a digital divide and it’s getting wider

No one wants to be on the wrong side

Many communities are forced to act

Someone has to Overbuild

“We’re losing a generation of highly educated, skilled workers and entrepreneurs that are leaders in the digital economy,” said Natalie Roper, executive director of Generation West Virginia, a young professionals group. “They have moved to other states that have invested in high-speed internet infrastructure


Why Broadband Is Important:Community Benefits• FOR COMMUNITIES, high-speed broadband will:

• Bridge the digital divide by giving all residents access to broadband;

• Add educational options such as distance learning and experiential learning;

• Use telemedicine to monitor and health and safety of the frail and elderly;

• Install intelligent traffic systems to measure traffic flow and adjust traffic signals in real time;

• Enable municipal efficiencies;

• Significantly reduce response time for first responders.

‘Community Broadband’ is about Communities not Broadband

Big Thank You to GoogleFiber

Tanked the bps/$ economics

Highlighted the Digital Divide

Forced the Incumbents to act

Proved the current broadband ecosystem is broken

First: Google/Alphabet wins regardless of who delivers high speed broadband for the simple reason a 4K ad cost more than a 1K ad

Agenda


Access Networking it Tough




Access is not an Electrical Engineering problem

It’s a Civil Engineering problem

Moore’s Law Doesn’t apply

Access is not for the faint of heart

If it did, a bucket truck would fit in your hand

Broadband Challenges: Realities


Broadband Challenges: Realities

Miles of facilities (wires/local loop) connecting every building in the serving area

Specialized Outside Plant electronics many attached to utility poles or under ground

Onerous federal and state and local regulations in a politically charged environment

Real operational challenges -- lightning, floods, radon gas, backhoe fades and squirrel chews.


Broadband Challenges:Central Offices

Residential

Enterprise

Mobile

• One central office (CO) may support

– 10K+ residential subscribers

– 10K+ mobile subscribers

– 1K+ enterprise customers

• There are 1000s of COs

• CO is a service provider’s “gateway” to its

customers

• CO represents a great vantage point for a

service provider

– Enable new services to customers

Broadband Challenges:Utility Poles

The biggest barrier to Broadband success are the Utility Poles!

These are Green Fields!



Over Builder Options?

Internet Access Only Not Enough Cord Cutter to Break even

2- or 3-Play Video infrastructure costs and content

costs raise breakeven

Open Broadband Access ?

GoogleFiber proved one company can’t do it all themselves

Why Open Source for Open Broadband?

Lot’s of them (20k CO’s in USA)

How is Broadband Different?

Small, Medium and Large

10-20,000 I/O ports per CO
