Interesting links, week 38, 2023
Interesting telco/tech news for this week:
- AWS: Cannot Escape IPv4: interesting feedback from the AWS trenches about the actual use of IPv6 in the AWS services. Not looking great.
- Switzerland releases 3.4 GHz-3.5 GHz spectrum for 5G private networks: Swiss is opening the 3.4-3.5Ghz range for CBRS like uses, althought it will be via some campus license and a frequency range a little bit different from the other EU countries, which probably will result in some modest adoption, but a nice step forward.
- Necesitas una nueva SIM para usar el 5G+ [ES]: in Spanish. It looks like Orange Spain has deployed a SUCI-only SA core, requiring customers to change their sim cards. The funny bit is that this is absolutely no required if you accept a transition period where SUCI with null cipher is used, i.e. what will likely happen with existing sim. osmocom/pysim folks detail the enablement of SUCI on the SIM card filesystem, i.e. TL;DR a JSON with the public key should preexists in the 5G+ compatible card/eSIM, as well as other parameters such some services / routing indicattor, which will be given during “register request”.
Found a couple of nice links this week on the Internet:
- onos-e2t: An interesting implementation where the RAN is implemented in a software defined manner, where E2AP/F1AP over SCTP is converted to Protobuf from ASN1 and vice-versa.
- loon library: This is a post-mortem document of the loon project. I was very lucky while working at Telefonica to be part in the team having interactions with them. The feedback we all learn on those “eNB in the sky” is potentially interesting for the next wave of gNB in LEOs, that seems to be lurking. Check on the so called temporospatial (!) Software Defined Network paragraph.
Listened a couple of nice podcasts this week:
- telecom.com: China/us telco tech and openran geopolitics.
- EP. 117: NINTENDO KNITTING MACHINE: Historian Racheil Weil returns to the show to discuss the Nintendo Knitting Machine, a never released knitting machine toy powered by the NES.
