Radio relay: High-speed Internet access

The advantages of radio relay in a nutshell:

Slow or unreliable lines slow down digital processes, especially at locations without a fiber optic connection. Projects are delayed, data transfers stall and productivity suffers.

With SAVECALL radio relay solutions, you can connect your locations quickly, securely and independently of existing infrastructure. We supply high-performance wireless connections that can be flexibly expanded. As a backup or primary connection, they guarantee maximum stability. Even where cables end.

Prerequisites

The point-to-point radio link is a way of connecting two nearby company locations via the so-called air interface.

Prerequisites for successful installation include

max. 50 km distance between the two locations
Line of sight
Approval of the installation of the radio relay system and associated work on the building by means of the building owner’s declaration (GEE)
Technical building requirements (statics, etc.) that make it possible to install the radio relay system

Bandwidth

Scalable bandwidths between 2 Mbit/s and 1,000* Mbit/s are available to you in upstream and downstream.

Point-to-point radio relay: How it works

Technical sketch of a radio link: Company location A and company location B directly connected via radio antennas.

What is point-to-point radio relay

Point-to-point radio relay is a high-performance site coupling solution based on wireless local loop technology (radio relay technology, “WLL”). It offers a permanent connection between two locations on contiguous or closely spaced company buildings as a complete solution for the transparent transmission of IP packets.

The service includes the provision of a radio link between the neighboring locations, which is usually installed on the roof of the customer locations.

To realize the radio link, there must be visual contact between the two directional radio antennas of the locations.

Point-to-point radio relay is ideal for companies that:

Want to connect neighboring locations with each other
Have a need for very high bandwidths
do not have fiber optic connections between the buildings
want high availability
attach particular importance to media redundancy
require fast realization and provision of high bandwidths
Also ideal for data center coupling on campus

How radio relay works

The radio link is established via the so-called air interface.

In the wireless local loop, the route from customer location A to customer location B is bridged by a radio field, e.g. with a frequency of 26 GHz.
The antennas must have an uninterrupted line of sight at the customer locations.
An antenna with a transceiver unit, the outdoor unit (ODU), must be installed on the roof of the end customer site.
The end customer connects their network to an interface of the indoor unit (IDU). The ODU and IDU must be connected with a cable.

Realization & procedure

General procedure

The commissioning of point-to-point radio relay takes place in stages:

1

Checking the general availability

2

Capacity and bandwidth request for regional network planning

3

Signing the contract, obtaining the GEE and commissioning

4

Commissioning of the “Line of Sight” check

5

Site inspection to clarify the structural measures

Realization

In the wireless local loop, the distance from the roof location of a base station to the end customer’s location is bridged by a radio field (e.g. with a frequency of 26 GHz).
The antenna at the customer’s roof location must have an uninterrupted line of sight with the antenna at the roof location of the base station.
An antenna with a transceiver unit, the outdoor unit (ODU), must be installed on the roof of the end customer site.
The end customer connects their network to an interface of the indoor unit (IDU). The ODU and IDU must be connected with a cable.
