FREQUENTLY ASKED QUESTIONS

Internet Protocol Security (IPsec) is a secure network protocol suite that authenticates and encrypts the packets of data sent over an internet protocol network. It is used in Virtual Private Networks (VPNs).

Internet Protocol security (IPsec) uses cryptographic security services to protect communications over Internet Protocol (IP) networks. IPsec supports network-level peer authentication, data-origin authentication, data integrity, data confidentiality (encryption), and replay protection.

An Internet Protocol address (IP address) is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. An IP address serves two principal functions: host or network interface identification and location addressing.

Public IP addresses (sometimes called Internet IPs) are what differentiate all devices that are plugged into the public internet. An IP address works similarly to a physical location’s street address. Just like a street address directs mail to the addressee, IP address directs data to the appropriate device.

An Access Point Name (APN) is the name of a gateway between a GSM, GPRS, 3G or 4G mobile network and another computer network, usually the public Internet.

A device making a data connection must be configured with an APN that will be sent to the mobile network carrier. After analyzing this APN, the carrier will determine what type of network connection should be created. For example: which IP addresses should be assigned to a wireless device, which security methods should be used, and how, or if, it should be connected to a private customer network. An APN can be either public or private.

There are also SIM cards packages in ceramic miniature packaging that can be soldered directly to the PCB – Printed Circuit Board of the device. There is more than one type of eSIM. Most common is MFF2 type with 8 pins. In addition, an eSIM can be embedded in other integrated circuits devices which are also soldered directly to the PCB. The eSIM card is not removable, but could be reprogrammed with another network profile if required to change the network provider.

Machine to machine (M2M) refers to direct communication between devices using wired and wireless communication channels. In different industries such communication may be referred to by different abbreviations (SmartGrid, Smart Buildings, Smart Cars and alike, V2V, V2I and V2x - "vehicle to vehicle", "vehicle to infrastructure" and "vehicle to anything").

IoT is an acronym for Internet of Things. Wikipedia defines IoT as the network of physical devices, vehicles, home appliances, and other items embedded with electronics, software, sensors, actuators, and connectivity which enables these things to connect and exchange data.

Many consider M2M to be at the core of IoT. In this regard IoT is simply a broader concept. IoT lets devices speak with one another through a much larger network. M2M is what provides the Internet of Things with the connectivity which enables capabilities that would not be possible without it.

The Home Location Register (HLR) is a database that contains details of each SIM card subscriber that is authorized to use a particular GSM network. The HLR is maintained by the network operator. Each SIM has a unique identifier called an International Mobile Subscriber Identity (IMSI) which is the primary key to each HLR record.
