Maritime customers often ask what frequencies and network identities they can use for their on-vessel networks. Frequencies and network identities are completely separate questions, but both are determined by where you are. Network Identities Quick technical background: What is a network identity? The network identity is a 5- or 6-digit code that identifies a cellular […]

This article tells how the Legba SatSite is an exceptional choice for a low-cost, single-box DCSA IoT data gateway on a vessel (as described in Section 3.1 of “IoT Container Standards: IoT Standard for Gateway Connectivity Interfaces“). What is a “data gateway on vessel”? The DCSA IoT architecture defines a gateway as an entity that

This article describes the “local breakout” function in YateBTS/OpenBTS GPRS cells, where user IP traffic originates directly from the cell site instead of from a centralized GGSN in the core network. Standard GPRS Architecture The standard GPRS data network has these parts: BTS – the actual radio basestation, which handles user traffic up to layer

When we are talking to new customers, there are some common questions that keep coming up. The Basic Basics A lot of the most basic information is covered in this post, but we pulled out some common questions here. Q: What is a “private network”?A: In this context, a private network is a radio network based

The purpose of this article is to provide some background for network managers about the kinds of radio hardware diagnostics that are available from typical radio basestations (GSM BTS, UMTS NodeB, LTE eNodeB, 5G-NR gNodeB, etc.). They probably will not see these diagnostics directly, only the resulting warnings and alarms, but it takes some of

This article is about the state of the LTE/5G private network market, world-wide. From a regulation standpoint, there are two types of private networks: true private network – Installed and operated independently by the owner. This requires the owner to have legal access to spectrum, and there are several ways that can happen. pseudo-private network

Various analysis reports place the value of the private network market at around $3.5B in 2020 and growing at about 13% per year. Where are these networks and what are they used for? And why do customers install them? In a different article, we addressed the question of where these networks are and what industries

This post describes the operation of the MTC Physical Downlink Control Channel (MPDCCH) for sending downlink assignments and uplink grants to the client device. Purpose of the MPDCCH In LTE-M, radio resources assignments (the times and frequencies when a device is expected to receive or transmit) are dynamic, for both downlink (“DL”, network to device)
