Harri Holma’s Post

Goodbye 3G! The last 3G network was closed down in Helsinki last night. Kenny (Nokia 6650) and my WCDMA book can be retired to the museum now. WCDMA theoretical peak rate was 2 Mbps (and practical 0.4 Mbps) while the live 5G network in Helsinki provides 2 Gbps. Impressive evolution in the last 22 years! The data rate has more than doubled every two years since 2002. And more evolution coming with 5G-Advanced and 6G.

HSDPA (single carrier) provided quite nice performance before 3G was closed

HSDPA 5 codes and QPSK with 1.8Mbps... what a jump when we got 16QAM and doubled throughput to 3.6Mbps. That happened during the Telcel Mexico (AMX/CARSO) rollout with Flexi BTS and WN3.3 (the first Flexi SW supporting for 850MHz 3G). Good times and so much fun integrating Nokia 3G in many places in MX.🌮🇲🇽🌵

Harri, I still have this book of yours. Will have to retire it. Amazing actual 5G speeds in Helsinki. It must be on mm wave band

Kenny has also GSM functionalities, it is a dual mode phone. You should be able to keep on using it... for ever.

In Germany 3G was off since 2021 , why things took long time in Helsinki :)

Oh yes very good memories Harri ! Other thing to put in the museum is the DUMBO if you remember, only old people can :-)), the first 3G mobile BIG BOX prototype that we've being using to test 3G mobility and performance. Indeed, 3G is still used and it has opened the door to high speed rates. Well done !

Nokia 3G RNC 1.0 release program, with the 1st NRT RAB coming out, followed by AMR, CS T, CS NT and then multi-RAB, in later program releases. Those were the memories along with this iconic book, in old times 🙂
