| Just hours before the expected decision by the UK government to rule that Huawei’s technology will be removed wholesale form the UK’s national communications infrastructure, one of the expected beneficiaries from the move, Nokia, is claiming it can “instantly” migrate as many as five million legacy 4G radio units to 5G.Nokia believes the ability to upgrade 4G/LTE radios via a software update will significantly smooth out the deployment of 5G/NR FDD, avoiding costly and disruptive site visits. Nokia has a customer base of 359 4G/LTE customers with deployed FDD RF units, most of which it says are possible to upgrade, and sees the new plan as providing a new and smoother way for operators to build 5G/NR coverage in lower bands via spectrum refarming. It claims its radios are “market leading” and outperform all vendors according to independent testing.Nokia also has Dynamic Spectrum Sharing (DSS) already in live networks covering 2G/GSM-3G/WCDMA-4G/LTE, and recently introduced DSS for 4G/LTE-5G/NR. This capability is designed to complete a DSS solution, covering all access technologies and making the radio frequency refarming to 5G/NR a simple and efficient process. In a typical case, DSS will be introduced to one or a few 4G/LTE bands, which are then combined with carrier aggregation between other bands running pure 4G/LTE or 5G/NR.“While Open RAN promises software upgradability to ease transitions between ‘Gs’ and add new features, Nokia’s Flexi and AirScale portfolio shows it is ahead of the game by providing a software upgrade to transition over five million 4G radios to 5G,” observed Chris Nicoll, principal analyst at ACG Research, looking at the new development. “Efficient FDD spectrum refarming is critical for fast, broad and deep 5G deployments. With Nokia supplying the majority of the world’s top 4G operators, supporting key advanced features such as DSS helps those operators lead with 5G.”The coronavirus is changing everything about how people work, and will do so permanently. It added that even though the working world was experiencing unprecedented uncertainty, there were two things that should be borne in mind: the virus will pass, and at the other side of the pandemic, the world of work will look very different. -- ???????? | |||
