TADHack and TADSummit dates through 2023

The first event of the year is TADHack Open, 25-26 March, the weekend before Enterprise Connect.

For TADSummit 2023 we’re thinking about the Thursday/Friday before Network X in Paris. With TADHack Global over that weekend, so the dates would be:

  • 19-20 Oct TADSummit in Paris
  • 21-22 Oct for TADHack Global
  • 24-26 Oct, Network X where we have a TADHack session

Please let me know what you think of this idea? Nothing is set in stone, we have complete flexibility. Thanks.

IoT+ Review TADSummit 2022

The last TADSummit 2022 reviews covered the presentations focused on IoT, a maturing segment of programmable communications, that’s moved beyond the silly hype. The ‘+’ is because I include Mark White’s M&A presentation as well.

Thank you to STROLIDBroadvoice / GoContactRadisysRingCentralStacuity, and AWA Network / Automat Berlin for sponsoring TADSummit 2022. And thank you to all the presenters and attendees in making the event excellent.

Fixed Wireless Access with 5G

Kyllesbech’s analysis reminded me that about 30 years ago I was modelling LMDS and MMDS as broadband access options. One piece of a BT board analysis that also included satellite, LEO, MEO, balloons, xDSL, mobile networks, and more. I was even researching blue-green laser satellite communications (penetrates the sea for submarine communications) to understand their link budgets.

FTTH has always been the destination, but there have been so many other options along the way, xDSL being the big one for many telcos, also cable. FTTH’s problem is it requires a ‘strong’ commitment, investing billions in the ground. And it only gets more expensive the longer you wait, so it encourages more waiting.

BT could have roll-out FTTH throughout the UK in the ’90s, the market was exploding. Some countries have achieved close to 100% FTTH coverage, e.g. Singapore and South Korea. But that took a strong push from the government. BT never had that, just words from the government about UK technology leadership.

Many of the alternatives are more of an incremental investment, spend less today, but you’ll need to spend more tomorrow to get to the end goal. With 4G/5G, the telco has made the investment in the spectrum license, some customers already self select to mobile broadband only, so extending a fixed offer over the mobile network is incremental as long as you do not look too closely at like-for-like performance to FTTH.

Kyllesbech’s analysis reminded me of my LMDS / MMDS analysis, old-school fixed wireless access. The core problem is noise, fiber is Gaussian, wireless is Rayleigh. Which means you need a big fat link budget for indoor wireless to be even close to FTTH in reliability. And sometimes it’s just not going to work, e.g. wet leaves on a foggy day with the indoor unit behind a damp brick wall. Fiber can deliver gigabits to each customer regardless of weather. When storms hit and the electricity goes down, FTTH just keeps on running with a generator at home, I’ve done that many times. The same is not true for cable, as their access network is active not passive, the mobile network slows to a crawl as many use it as broadband back-up.

As a broadband customer I’ve had FTTH for about 15 years, using some of the work I did at the Full Service Access Network initiative in the ’90s. Things just work, generally reliably, the only issue has been the CPE failing, which I fixed myself. FTTH is nice because I do not need to deal with my telco so often, which generally leads to sadness and frustration.

10 million voice subscribers now benefiting from cloudified voice production – hmmmm

Interesting article with no explanation on what the customers’ benefits are, only the telco’s. Quoting from the article:

Telekom has created an innovative and highly-collaborative multi-vendor ecosystem to deliver on the vision of this highly-automated, cloud-based architecture. Current partners are Juniper Networks (Cloud Infrastructure & Prime Integrator), Mavenir, Metaswitch, Hewlett Packard Enterprise, Lenovo und Red Hat. Due to the high level of disaggregation and the horizontal cloud approach, more technology partners can easily be added as the demand for services grows.

Mobi to use WG2 Core hosted on AWS

Mobi is a wireless service provider founded in 2004 and based in Honolulu. It provides 4G/5G services across the islands. It plans to launch a cloud-native mobile core from Working Group Two hosted on the Amazon Web Services (AWS) cloud, to launch a nationwide service on T-Mobile’s network.

The move to owning a core as an MNVO is because: “Being a light MVNO can be a real bummer sometimes,” Justen Burdette, Mobi’s CEO, told Light Reading. “I didn’t want to be stuck in that boat ever again.”

The spin is on service innovation through APIs. Though to date MVNOs in the US have focused on price, due the lack of competition in the US mobile market. BTW TMO is rumored to be considering buying Mint Mobile, pricing in the range of $600 million has been mentioned in the past. MVNOs tend to get bought up when they become too popular, which Mint is doing.

This is a significant step forward for Working Group Two. It’s not being used as an adjunct core, it’s the core network. Here are some of WG2’s TADSummit presentations from over the years:

Let’s see if Mobi focuses on the usual MVNO value play, or tries to differentiate with services on its WG2 core.
