As a completion of the previous post, 5G technology began to form a jump in wireless communications. This post will include a type of communication that 5G offers to users, which is D2D. As a matter of fact, the direct mobile devices will establish the interaction without the use of base stations (BS). To be specific, the data will not be transmitted through the access points in fixed infrastructure. Furthermore, two primary classifications of D2D communication: out-band and in-band. Both classifications will be discussed briefly in the comming posts.

Let’s learn together !!! #Question 3: What were the main challenges faced by mobile operators during the initial adoption and deployment of VoLTE, and how have those challenges evolved over time? #Answer 3: Initial VoLTE deployment presented several hurdles for operators: i) Network Infrastructure Upgrades: Transitioning from circuit-switched to packet-switched architecture for voice services demanded significant upgrades to existing network equipment and the deployment of IMS (IP Multimedia Subsystem). ii) Handset Compatibility: Early VoLTE adoption was hindered by the limited availability of VoLTE-compatible handsets. iii) Interoperability and Roaming: Ensuring seamless call handover between VoLTE and legacy networks (2G/3G) during calls and roaming posed technical complexities. Over time, these challenges have been largely addressed through: i) Standardized IMS Implementations: Standardization facilitated smoother interoperability and reduced deployment complexities. ii) Increased Handset Support: The widespread availability of VoLTE-capable smartphones significantly expanded the user base. iii) VoLTE Roaming Agreements: Operators established bilateral agreements to extend VoLTE services across different networks, enhancing the user experience. #CoreNetwork #VoLTE #IMS #CoeurReseau

Today, I was asked a question about Sub-Carrier Spacing in 5G , and after doing some research, I found this very useful answer. Understanding Sub-Carrier Spacing in 5G from Low to mmWave Frequencies 📶 5G technology revolutionizes mobile networks by offering flexibility in sub-carrier spacing across different frequency ranges. From low frequencies (600MHz) to ultra-high mmWave frequencies (24GHz+), sub-carrier spacing is adapted for optimal performance. Here's a quick breakdown: ✅️ Low Frequencies: 15kHz for better range and coverage. ✅️ Mid-Band: 30kHz/60kHz, balancing capacity and coverage. ✅️ High Frequencies (mmWave): 120kHz for ultra-fast speeds in dense environments. 5G's adaptability to different frequency bands enables it to meet diverse network demands, paving the way for enhanced user experiences. #5G #Telecom #SubCarrierSpacing #NetworkTechnology #mmWave #Connectivity #TechInnovation

The cellphone networks yet again remain resilient and up and running during this catastrophic event. Several area LMR systems had diminished levels of working due to damage to towers. Those areas reverted to LTE networks using personal cellphones. I am not saying that we are the solution or we want to replace LMR systems all together. The big providers are building radios that have LTE connectivity but are pricing them out of reach of many agencies and jurisdictions. We want agencies to look at other options like firstnet or of course 911iNET to give you an option as a back up system or an add on to your current LMR systems. This way you can have true redundancy during any event that can put your LMR system at risk of failure. You don’t have to choose us, as multiple options are available. All I ask is that you have a back up.
