About 5G

I realised that I have not looked at Positioning techniques a lot in our blogs so this one should be a good summary of the latest positioning techniques in 5G. Qualcomm has a nice short summary here: Release 16 supports multi-/single-cell and device-based positioning, defining a new positioning reference signal (PRS) used by various 5G positioning

The premises of virtualization is to move physical network functions (PNF in hardware) into software and to design them in a way so that they can be deployed on a NFVI (Network Functions Virtualization Infrastructure, a.k.a. the cloud). MANagement and Orchestration (MANO) is a key element of the ETSI network functions virtualization (NFV) architecture. MANO

Cloud native is talked about so often that it is assumed everyone knows what is means. Before going any further, here is a short introductory tutorial here and video by my Parallel Wireless colleague, Amit Ghadge.   A simple explanation of Cloud Native by Antía Fernández López, Gradiant at @cambwireless #CWTEC #CloudNative #CloudComputing pic.twitter.com/0XkQAPmPNv — 3G4G

One of the interesting features of 5G is Ultra-Reliability and Low-Latency Communication or URLLC. It has been enhanced as part of 3GPP Release-16. A summary of the changes in eURLLC can be seen in the picture above.  This ATIS webinar that I blogged about last week covered this topic as well. For example L1/L2 changes

GSMA recently published updated “5G Implementation Guidelines: SA Option 2“. It explains the two types of SMS in 5G, the same way there were 2 types of SMS in LTE. Within 5GC, SMS Function (SMSF) supports SMS over NAS (SMSoNAS) defined in 3GPP TS 23.501. Besides, SMSoIP can also be considered as IMS based SMS

I have been thinking about the long term evolution of 5G and have now reached the conclusion that it would make sense in the long run to switch off non-standalone 5G. This would of course be only after 5G core has been tested and used extensively. Instead of writing my reasoning, here is a 10

With the mobile technology gaining even more subscribers and smartphones becoming common, the telecom services pricing that includes voice, SMS and data is falling. Many operators are now including bundles with generous amounts to satisfy everyone. In many European countries, it is very common to have plans with unlimited everything.  One of the reports that

Yesterday (2020-06-22) 3GPP uploaded the version 1.0 of TS 38.314 “Layer 2 Measurements” for 5G New Radio Rel. 16. I was wondering about the difference compared to the same LTE standard defined in 3GPP TS 36.314. The initial look at the table of contents shows significantly less measurements in the NR spec, but a new

SEPP (Security Edge Protection Proxy) is part of the roaming security architecture as shown in the figure above. Ericsson’s article, “An overview of the 3GPP 5G security standard” describes the use of SEPP as follows: The use of SBA has also pushed for protection at higher protocol layers (i.e. transport and application), in addition to protection

It’s been a while since I wrote detailed posts explaining UICC and SIM cards. Since then the SIM cards have evolved from Mini SIM to Micro SIM and Nano SIM. They are evolving even further, especially for M2M / IoT devices as embedded SIM (eSIM or eUICC) and integrated SIM (iSIM). Embedded SIMs (eSIMs) or embedded

Reliance Jio has recently been called as India’s first digital service provider (DSP), but what exactly is a DSP and how does an existing mobile network transform from the traditional communications service provider (CSP) to a DSP? Service Providers are also known as Telecommunications Service Provider (TSP) or Communications Service Provider (CSP). Basically, they refer to
