The E-network is a mobile communications network that operates in the 1800 MHzfrequency range and is divided into the E1 network and the E2 network. The E1 network was operated by the Thyssen/Veba consortium, later by E-PlusMobilfunk. The E2 network was operated by Viag Interkom, now by O2 Germany.
The E networks, which operate in the 1800 MHz frequency range, are mobile communications networks in the DCS standard, Digital Cellular System (DCS), which is based on GSM. The higher transmission frequency of the E-networks means a shorter signal range, which results in smaller radio cells, but higher traffic capacities in terms of area. The coverage radii of the radio cells are about 300 m in metropolitan areas and about 8 km in sparsely populated areas.
The e-networks are characterized by familiar features, including call forwarding, call waiting, call waiting, three-party conferencing and short message service( SMS). In addition, there are some special features and service characteristics, such as roaming to D-networks. The E-network cell phones operate at powers between 0.25 W and 2 W; the device ID is queried by the radio switching center when logging in. It is also possible to block the terminal depending on the noted device status.
The network codes assigned by the regulatory authority RegTP are for E1: 0163, 0177, 0178, and for E2: 0176 and 0179.
