eNodeB (Evolved NODE B) - the radio of the LTE network
To summarize the point, the eNodeB does:
To better understand the concept of eNodeB, you need to have a clear image of its functions and how it communicates to other elements of the LTE network.
The sections below describe the eNodeB architecture and the role of each component, as well as our evolved Node B solution equipment.
We provide two types of eNodeB solution:
- SatSite 142 – full production eNodeB
- LTE LabKit – eNodeB for test and research
Main functions of the LTE eNB
How the evolved Node B communicates to other elements of the network
The LTE eNB communicates with the UE, other eNodeBs, and the Evolved Packet Core (EPC). It uses various interfaces such as the Uu, X2, and S1.
In order use a full production eNodeB you need a Spectrum License
Everyone who wants to buy an LTE eNB and use it for a Mobile Network or a private one needs to get a spectrum license. The radio spectrum is the range of frequencies of electromagnetic radiation. It includes their respective wavelengths and photon energies.
To get a spectrum license, you need to take part in a spectrum auction. A spectrum auction is a process that a government uses to sell the rights to broadcast signals. They divide limited spectrum resources over specific bands of the electromagnetic spectrum.
There is also the “ lightly licensed” option. You can register for a spectrum license with a small fee, like CBRS in the US. Of course, different countries may have different views about their spectrum resources. It’s great to see more spectrum available to both operators and new entrants. There’s still a lack of clarity of which bands, modes, and options will be adopted outside the US.
Types of businesses that need an eNodeB
Yate-based eNodeB solutions
We provide two types of eNodeB solutions for operators and private networks. Our solution is highly scalable and suitable for any operator size and structure.
Full production LTE eNodeB
SatSite model 142 is a self-reliant macrocell eNodeB solution. It can be configured via software to operate as a 2.5G GSM/GPRS BTS+BSC. There is no need for a CPRI because our eNodeB solution can work with any Ethernet backhaul. Finally, SatSite 142 has the largest power output of 20 watts RMS for LTE or GSM operation.
LTE LabKit - eNodeB for tests and research
The LTE LabKit is a Lab LTE ENB running on a small factor PC computer. It comes in a light package (5kg or 10 pounds, including the phones). It is intended for MNO laboratory use, IoT, and M2M application development. It is also used as a Callbox for IoT production lines, mobile phone vendors, and researchers.
