Webinar Overview

For WISPs, growth is no longer just a technical challenge. It is an economic one.

With ARPU largely flat across most markets, every decision around subscriber modules, access points, and upgrade timing directly impacts long-term profitability. The challenge is not just building capacity. It is doing so in a way that protects margins while allowing the network to evolve.

This webinar focuses on the financial realities of scaling a WISP network, including how to transition from legacy platforms such as ePMP™ 2000, ePMP 3000, or competitive solutions, to the ePMP 4000 series in a way that maximizes return on investment.

We will also explore how newer subscriber modules like the ePMP Force 4518 and 4616 help WISPs match cost and performance to specific deployment needs, whether extending range, increasing sector efficiency, or optimizing cost per subscriber.

Instead of requiring disruptive upgrades, ePMP enables a step-by-step evolution model. Operators can enhance performance, introduce new SMs, and increase capacity incrementally without resetting their entire cost structure.

What You’ll Learn

  • Why ARPU versus subscriber cost is one of the most important equations in WISP profitability

  • How to evaluate 5-year cash flow across different subscriber and platform strategies

  • The economic impact of upgrading from ePMP 2000, ePMP 3000, or legacy 11n and 11ac networks to ePMP 4000

  • How ePMP Force 4518 and 4616 allow a blendeded CAPEX approach enabling better alignment between cost, range, and performance

  • How to start with a small cell or low density sector and expand as you prove the take rate

  • How to scale subscriber density without breaking your cost model

I appreciate the addition of the 4518, and I appreciate the return of AP mode on the SM’s. (although its inconsistently previously been 10 or 12 SM’s, and now it’s 8 SMs depending on the generation). But nonetheless, these two options are good for WISPs to obtain smaller markets with lower initial risk. That’s all a good thing. :+1:

The major stumbling block we’ve always seen with adoption of 4000 was the decision by Cambium to not have 4500 series SM connect to 3000 series APs. I know I’ve pleaded about this before, but to me that was your fatal flaw that limited deployment of 4000 series gear. That has forced WISPs into basically forklift upgrades. Even though Cambium officially understands, and even brags about incremental upgrades, your decision to choose to not support 4525/4518 on 3000/3000L APs basically forces upgrading perfectly competent and stable 3000 APs with new/beta 4500’s, and that was and remains a fatal flaw.

Anyway, I have pleaded the case many times about that, so it is what it is. :person_shrugging:

And, of course it follows that when the 5000 / Evo (or any future generation) comes out, it will also be the same situation? No compatibility between the 5000 series SM’s and the then stable and mature 4500 / 4600 APs folks are currently deploying. All that investment and hard-earned stability will have to be forklifted again. Either that or people will have to again choose to not deploy 5000 series SM gear as early as they otherwise could. :person_shrugging:

Anyway, good webinar, and I appreciate seeing the 4518, and nice to see the return of AP mode on 4000 series SMs.
