Cellular Software, Support & Licenses
Cellular software refers to the programs used to design and manage cellular networks, such as software for managing a cellular base station or a complete 4G or 5G network. In the Internet of Things (IoT) space, cellular software can mean the software used on devices that communicate using cellular signals.
Cellular support is the assistance offered to customers, both end-users and businesses, in using cellular technology. This might include troubleshooting connectivity issues, providing guidance on the use of cellular devices or networks, or supporting the implementation and management of cellular-based systems.
Cellular licenses are the legal permissions required to use certain cellular technologies. For example, mobile network operators need licenses to use specific bands of the radio spectrum for cellular communication. These licenses are typically awarded by government regulatory bodies. In addition, certain cellular technologies may be protected by patents, and using these technologies may require obtaining a license from the patent holder. This is common in the cellular industry, where standard technologies like 4G and 5G are built on patented innovations.
Ethernet hubs, switches and routers connect computers to networks, devices and other computers.
Ethernet hubs are the least intelligent of the three devices. They simply take any message that is received and transmits it to every other device connected to that hub. For example, if CPU 1 on a network wants to send a message to CPU 5, it will send that message through the hub.The hub will then take that message and send it out to every connected device on that hub regardless of the intended target. When CPU 5 receives that message and wants to respond, it will send its response through the hub which sends it to every connected device. Ethernet hubs do not manage any data that is sent and tend to bog down networks. They also do not offer much security for the network. For these reasons, Ethernet hubs are are being replaced with network switches.
Switches transmit data from one device to another on the same network. Unlike a hub, switches use a switch table to learn where data came from and where to send it. Switch tables store Mac addresses and device ports. By storing this data, a switch can operate more efficiently than a hub, greatly reducing the traffic within the network.
Routers transfer data between devices while learning the location of those devices within the network. They are also a junction between two or more networks. An example of this would be a home router where the home network is connected to the Internet. Another example would be when the router connects two or more networks with different business functions. In addition to connecting two or more networks, a router offers important security features that help protect the network.
