Telco Terminologies

07.09.2023 | A SIM card is a very small circuit board. As a key component of the phone, it functions like a miniature passport, identifying the user in the mobile network and thus enabling him or her to use it for mobile telephony and data communications.

21.08.2023 | These connections provide high speeds in the gigabit range. In a fiber-optic trial arrangement, 153 million gigabits per second were achieved at the end of 2022. More informationen:

• O₂ Telefónica and BUGLAS agree on framework agreement for fast fiber-optic connections

• Glass fiber and directional radio provide for fast 5G expansion

10.08.2023 | 5G technology offers extremely low latency, the delay between sending and receiving information is 1 millisecond compared to 200 milliseconds for 4G. More information:

• Telefónica Germany, Hewlett Packard Enterprise and wheel.me cooperate on mobile robot solutions

03.08.2023 | Network slicing occurs most often in the context of 5G networks. In this process, the network or a part of the network is sliced like a cake into pieces according to demand. These network slices then function as their own virtual, separately secured network within the overall network, which can be configured to meet different requirements. More information:
