This article tells how the Legba SatSite is an exceptional choice for a low-cost, single-box DCSA IoT data gateway on a vessel.
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.
The FAQ for private network customers.
The global private network market is estimated at around US$3.5B already. Where are these networks and what are they used for? And why do customers install them?
We do not just supply the radio network, but all of the planning, testing, and management the make the radio network useful.
Unlike later technologies, GSM can provide full service to device without full authentication. This can be useful in some private networks, allowing a device to bring its own SIM without needing a roaming agreement.
Cell broadcast (CB) is a way to deliver a text message to large numbers of handsets over the cellular network. Its main use today is the delivery of Public Warning System (PWS) messages, also called CMAS, ETWS, or other names in different parts of the world. The Legba Lab Kit is an easy and inexpensive way to generate PWS test messages on your bench.
Many 4G networks cannot carry plain old telephone calls, so many mobile operators support voice calls by transferring the handset to a 2G or 3G network for the duration of the call. The procedure for doing this is called “Circuit-Switched Fallback”, or CSFB. CSFB is an interesting procedure from a network operation perspective and from a security perspective. With a pair of Legba Lab Kits, one in 2G mode and one in 4G mode, you can reproduce and modify the CSFB procedure on a test bench.
