Speeding up Fiber rollouts

•Arm could change licensing to phase out CPU licensing. Could this affect Mikrotik?
Qualcomm claimed in its filing last week that Arm has already told at least one device maker that uses Qualcomm’s processors that it will need to obtain a “new direct license from Arm” in the future to use Arm-powered silicon. This new license will apparently require product manufacturers to pay royalties directly to Arm for every Arm-based device sold. If these makers do not accept the license, “they will be unable to obtain Arm-compliant chips from 2025 forward,” Qualcomm alleged.

WIFI calling port forwarding

Recently I came across a need to do some port forwarding for wifi calling. I have assembled a resource guide to help you if you need to do such things. IPSEC should be allowed per RFC 5996 https://tools.ietf.org/html/rfc5996 for all wifi calling

Verizon

UDP ports 500 and 4500 open to sg.vzwfemto.com and wo.vzwwo.com

TMobile

Also whitelist the CRL server for DIGITS OTT and WFC 1.0: crl.t-mobile.com 206.29.177.36

AT&T

Any of the above is subject to change.

Some Mikrotik SXT photos and first thoughts.

I have been wanting to do some photos and thoughts on the Mikrotik SXTR-LTEs and other Mikrotik LTE products. I recently fired one up using dual sims. One is from Tmobile and one is from At&T.  Verizon is pretty nonexistent in my area. I am about 2.5 miles away from a Tmobile tower and about a mile from a fiber-fed AT&T monopole.

As you notice in the following photo I am pretty buried in trees.

My view of the tower. Notice the high-tech holder.

Some initial notes.  Setup of LTE is a very easy process as far as the mikrotik is concerned.  I literally had to put in some information in the APN and that was it as far as LTE goes.  I did set up standard Mikrotik stuff (DHCP server, security, etc.).

Adding the second sim card can be a huge pain due to the location of the sim card slot.  Luckily I had some tweezers that were angled to be able to slide the card in the slot.  These were part of a dental kit I picked up off Amazon for releasing stuck SFPs and the like.

Look for a more in-depth series on Mikrotik LTE coming soon.

Cisco and Verizon demonstrate multi-haul

As Internet traffic grows and becomes more dynamic, optical transport networks for sub-sea, terrestrial long haul and metro need more capacity. The ability to deploy capacity quickly is equally important to handle the increasingly dynamic nature of the traffic. The concept of a multi-haul transport platform, as introduced by Andrew Schmitt of Cignal AI, becomes very appealing for achieving this ability to scale with speed while maintaining operational simplicity – a single platform for all requirements. A critical element of the multi-haul optical platform is the flexibility of the coherent optics to be tuned to fine granularity in order to meet the reach-capacity target of any given network.
