Upgrade Your Antennas: Nokia Turns 4G into 5G with a Click
Hey, network nerds! Nokia just dropped a game‑changing hack: a software‑only upgrade that flips your old 4G/LTE radios into slick 5G/NR guns.
Why It Matters
- On the ground right now, about 1 million radios will get the jump.
- By year’s end, that bumps up to 3.1 million.
- Fast forward to 2021, we’re talking over 5 million light‑year‑ready units.
The beauty? No extra hardware, no costly site visits—just sit back and let the firmware do the heavy lifting. It’s like upgrading from a flip phone to a smartphone—only slower and cheaper.
Breaking Down the Band Shift Magic
Telecom gurus are used to the glitz of TDD cmWave and TDD mmWave deployments, but the next blockbuster wave comes from turning the good old FDD bands into 5G havens.
- TDD gives you killer coverage and bandwidth when you pair it with the already‑deployed FDD infrastructure.
- Coupling that with Carrier Aggregation (CA) is pure gold for operators.
By letting your 4G radios take a software boot, Nokia smooths out the FDD transition—no need for scare‑crow pilots or rewriting knots on every site. A massive fleet of 359 customers, each with FDD‑ready cards, can hop onto 5G by pressing “update.” Easy.
Nokia’s Winning Formula
Nokia’s 4G/LTE hardware is a market champion (verified by indie tests). To top it off, they’ve woven Dynamic Spectrum Sharing (DSS) into every radio stack—from 2G all the way to 5G.
Imagine DSS like a universal remote that switches between 2G/3G/4G/5G modes in one go. When you throw it into one or two 4G bands, carrier aggregation kicks in to mix pure LTE or pure 5G streams—all hassle‑free.
The result? Industry savings that could reach tens of billions of euros—talk about turning a $5G upgrade into a $5 billion deal!
Industry Voices
Chris Nicoll (ACG Research) hammered it home: “Open RAN’s promise of upgradability is real, but Nokia’s Flexi & AirScale are already flipping 5 million 4G radios into 5G. A super‑efficient way to refarm FDD spectrum.”
Tommi Uitto (Nokia’s Mobile Networks President) chimed in, “We’re the world’s top 4G radios provider. This move is a lifesaver—customers get 5G ready without the headache or extra spend. It’s a win‑win.”
