Technical Guide to Mobile Data Solutions for International Connectivity

Cellular data, commonly referred to as mobile data, has transformed the way we work, live and browse. To resolve the slightest doubts, we just toggle on the mobile data, type our query on the internet browser and shoot the solutions. A few decades back, we can say it was a necessity, but now in the present time, it has become a convenience.

Further, to understand the paradigm shift in mobile data technologies, take a tour of this guide till the end. 

Overview of Mobile Data Technologies?

Mobile data opens up a world of internet access that helps you to browse anything, anytime, from anywhere across the globe. Whether it’s playing the latest video games, streaming the top charted movies, or connecting over video calls with your loved ones, everything requires a stable mobile data network.

The lightning speed of technological advancements has welcomed the eSIMs, giving tough competition to the traditional SIM cards. The transformation has welcomed new possibilities and given, revamping old techniques, but also challenged the physical sim architecture and the way of working.

Traditional SIM Architecture vs. eSIM Technology

Physical SIMs are small chip-removable cards that are inserted into devices, whereas eSIMs are embedded directly in the device hardware and can be operated remotely. But as both have different attributes, features, and functioning. Take a look at the limitations and architecture of both of them. 

Physical SIM Card Limitations

The introduction of eSIMs has challenged the physical SIMs existence. Ahead, this transformation has highlighted the traditional SIM cards’ limitations, encouraging people to reconsider their decisions that they still use the physical SIM or should shift to the new and highly advanced digital ones. This comes out to be challenging while traveling to another country. But there is a relief for the USA travelers, because esim usa travel options provide instant activation, to access hassle-free and in minute purchases. 

To make an informed decision, we have listed some of the universal limitations: 

• Physical Form Durability: Required dedicated slots and are prone to corrosion, tears, damage, and more. 
• Manual Installation Requirements: Required physical verification and installation procedures.
• Environmental Impact: The mass production and disposal of the SIM cards may impact the environment. 

eSIM Technical Architecture

The new and powerful eSIM includes eUICC that is compliant with the GSMA specifications. Take a look at the other prominent advantages it gives: 

• Multiple Profile Support
• Top Notch Security

Network Infrastructure and Coverage Analysis

After taking into consideration the difference between the traditional SIM and eSIM, take a look at its network infrastructure. 

Cellular Network Technologies

The cellular network is paramount not only for communications, but for entertainment and other browsing requirements. Take a look at the two different cellular network technologies: 

4G LTE

The 4G LTE includes several technologies mentioned below:

Spectrum Management

• Dynamic spectrum sharing to assist both 4G and 5G networks share the same frequency. 
• To increase the capacity and flexibility, licensed and unlicensed spectrum is utilized. 

Data Plan Architecture and Implementation

Take a look at the new and better data plan architecture and implementation that drives the best possible results. 

Traffic Management Systems

Take a look at what helps to manage the traffic and network resources efficiently: 

Quality of Services: 

• To help the video and voice receive the required bandwidth, the DSCP is employed. 
• Bandwidth allocation and throttling are integrated to manage the congestion of excessive traffic.

 Deep Packed Inspection: 

• To allow the network to analyze the content of data packets.
• To provide real insights into network traffic. 
• To suspect and detect the mitigate security threats. 

Roaming Technology

You might not know, but international roaming relies on complex signaling protocols: 

Signaling System 7 (SS7) Implementation

• HLR (Home Location Register) includes the location, services, subscriptions, and other important information. 
• VLR (Visitor Location Register) consists of a temporary database. 

Diameter Protocol

• Policy and charging control to evaluate the charging rules for roaming users. 
• Authentication, Authorization, and Accounting (AAA) is similar to SS7, but with upgraded and additional advanced features. 
• Service data flow detection and control to ensure the correct utilization and quality of services.

Security Architecture and Protocols

The next important one is the security architecture and protocols to ensure a safe and private usage.

Cryptographic Implementation

This includes two phases:

Authentication Protocols

• Mutual authentication to prevent impersonation attacks.
• Replay Attack Prevention Mechanisms to prevent the attackers. 
• Cryptographic Key Derivation and Management is used to encrypt and decrypt subsequent communication between the parties.

Encryption Standards

• AES-256 for data encryption. 
• Elliptic Curve Cryptography (ECC) for the ease of key exchange. 
• End-to-end encryption for application data

Network Security Measures

• Deep Packet Inspection for threat detection. 
• DDoS protection to mitigate the attacks, limiting and filtering the traffic. 

Performance Optimization Techniques

Take a look at the workable performance optimization techniques: 

Network Performance Metrics

• Follow the cell edge performance characteristics. 
• Measure the data speed and the delays in the data transmission. 

API Integration and Development
