Emergency call concept In-building solutions
Trigger to change concept
Emergency Call
▪ 3G system shutdown in June 2021
▪ UMTS2100 band will be transformed to LTE2100
▪ Customers without VoLTE capable UEs in indoor locations, connected to In-building solutions
may not be able to initiate emergency call
Legal Aspects
▪ Emergency call feature has to be provided
▪ Emergency call feature availability is not fixed assigned to any band or technology
Technical Aspects
▪ VoLTE and VoLTE emergency call features have to be enabled
▪ VoLTE capable UE and enabled service is required
▪ Emergency call via VoLTE network feature is in operation since 01.09.2021

Emergency call concept In-building Use Cases
Existing In-Building sites
New In-Building sites
• If GSM or LTE systems are deployed, no
measures are required for emergency call
• UMTS ONLY systems need to be upgraded to
LTE2100
• There is no 3G system planned in new inbuilding solutions
• 2G roll-out is not default anymore
Emergency Call
but
• If landlords or Vodafone Enterprise/Business
units require GSM for in-building customers,
GSM rollout is possible

➢ BB6648 – NOT supported
➢ BB6651 – NOT supported
DOT 2243 and IRU 2242 are supported by the below baseband units:
➢ BB5216, BB6630 – supported but phased out from 2023
➢ BB6631 – supported (possibility after BB5216, BB6630 phased out)
The below baseband units in Ericsson RAN Compute Group 1-3 will be phased out and Last Time Buy date is 31th December 2022
Due to DOT 2243 and IRU 2242 phase out, its baseband limitations and DOT 4479A CEPT nonconformity,
the preferred Ericsson Radio DOT system for planning is DOT 4475 or 4485 with IRU1648 or 1649

Radio DOT general placement – Same location per floors preferred
Floor based sectorization:
Scenario:
adjacent floor is fed from different cell / IRU
Placement:
same position on all floors
Performance:
allows RDs on one floor to counter the interference from adjacent floor
without creating handover boundaries or affecting the SINR
recommended solution, allows later sectorization
One sector over several floors:
Scenario:
adjacent floor is in the same cell
Placement:
zig zag pattern between adjacent floors
Performance:
allows RDs from adjacent floor to fill in „cold“ spots. Since they belong
to the same cell, no handover is created
not recommended, does not allow sectorisation between floors later

Planning Aspects
Radio DOT placement – Minimum mounting distances applied to all
DOT systems introduced into VFDE mobile network
Minimum mounting distance to ceilings:
Minimum mounting distance to walls and other objects:
➢ A = 0,2m (top of the bracket – ceiling)
➢ A (directions NOT intended to be covered) = 0,2 m
➢ B (directions intended to be covered) = 1 m
Planning Aspects
In order to avoid interference and/or increase in EMF safety distance the below minimum
mounting distances must be applied (A):
➢ DOT to DOT = 1 m (limited by EMF safety distance requirements)
➢ DOT to 3GPP pico in-building systems = 1 m (limited by EMF safety distance requirements)
➢ DOT to Ericsson WiFi AP unit = 1 m (limited by EMF safety distance requirements)
➢ DOT to generic WiFi AP unit = 2 m (limited by potential interference)
➢ DOT to generic in-building solution (EIRP < 35 dBm) = 2 m (limited by potential interference)
➢ DOT to generic in-building solution (EIRP > 35 dBm) = 5 m (limited by potential interference)

CEPT requirement in Germany – EIRP limits below 3400 MHz according
to ECC/DEC/(1)06*
Planning Aspects
CEPT B - Germany
CEPT requirement is limiting EIRP to -50 dBm/MHz per antenna (passive) below 3400 MHz. The limit is in EIRP which is impacted by
the below main factors in an in-building solution
➢ Equipment radio parameters and in-built band filters (if any)
➢ External filters
➢ External antenna gain (passive)
➢ For inbuilding deployment CEPT requirement as max -50dBm/MHz below 3400MHz is applied at the outer surface of the building in
special applications. (Only if zero indoor to outdoor signal leakage is granted. Windows and doors cannot be open at coverage area)

➢ does not allow open windows or doors within building surface
➢ requires measurement of building attenuation
➢ requires building in final state, completely built, to enable correct attenuation measurements

EMF considerations – DOT 4475 B78KB1B3 must be deployed with a
snap-on cover to be EMF touch safe
Sonder-Freigabe für Abstandsfreie Montage des Radio Dot

Basis ist der EMF Test Report: Ericsson Dot 4475/4485
B78KB1B3 (EU) vom 26.08.2021.
Für den öffentlichen Personenschutz gilt demnach, dass die
Abmessungen der Konformitätsgrenze des Produkts null sind
(intrinsisch Berührungssicher / Touch Compliant). Es besteht
keine weitere spezifische Anforderung für die
Produktinstallation durch den Hersteller.
Die Montage sollte bevorzugt an der Decke montiert werden.
Sollte dies nicht möglich sein so kann auch ein anderer
Montageort gewählt werden. Bis auf Weiteres ist zu weiteren
Funkanlagen ein Mindestabstand von 1m einzuhalten um
zusätzliche Umgebungsquellen hinreichend zu
berücksichtigen.
Planning Aspects
The Ericsson Dot 4475 B78KB1B3 has been tested using methods and procedures
specified in EN/IEC 62232:2017 [6]. The product was tested for localized exposure for
EU and markets employing ICNIRP exposure limits [1]. The results presented in section
5.1.3 show the compliance boundary dimensions of the product to be included in the
Customer Product Information (CPI) in order to be in conformity with EN 50385:2017
[7]. The product is touch compliant for both general public and workers in all directions
if a snap-on cover providing a separation distance of 0.01 m in the front direction and
0.02 m in the radial direction is mounted on it.
Alle anderen Regeln zur EMF konformen Installation (z.B.
Installation en mit Abstand zu Medizinprodukten* etc) bleiben
hiervon unberührt.

The Baseband unit is centrally located in the building.
The IRUs are distributed to different floors or building segment level.
The IRUs are grouped and not all has own fiber connection to Baseban
Port 1 of t he pri mary IRU recei ves the CPRI l ink from the Baseband uni t.
Port 2 of t he pri mary IRU is connected to Port 1 of the secondary IRU to
propagat e t he CPRI link.

RDI CAT 6A Cable
RDI (Radio DOT Interface) cables – CAT6 A (or higher) cable
requirements to connect Radio DOTs to IRUs
IRU 8846
➢ RDI, Radio DOT interface consists of the cables, connectors and patch boxes (if any) between the Indoor Radio Unit (IRU) and the Radio Dot
(RD)
➢ RDI with CAT 6A (or higher) cable is single RDI cable for signal transmission and power supply via PoE* (power of Ethernet)
➢ RDI runs power supply over CAT 6A* (or higher) cable compliant to PoE+ standard IEEE 802.3bt
➢ Power consumption of certain DOT units may allow longer cable run but European standards limit the maximum deployable CAT 6Acable
with PoE cable length to 100m
RDI CAT6 A (or higher) Cables with PoE maximal allowed cable length is 100m at VFDE Network
(limited by ETSI norm)

➢ Fiber must be compliant to ITU-T G.657 A2/B2 for
bend intensive single mode fibers. (1dB loss bend
radius of 7.5mm)
➢ Fiber must be compliant to IEC 60793-2-50 types
B.6.A and B.6.B. Reduced bend radius single mode
fibers suited for fiber riser application where cable
routing and bending is not well controlled.
➢ Optical fiber must have an attenuation <0,4dB/km
@ 1310nm
➢ Maximal cable length between IRU 1649 and RFX
1110 is limited by the DC cable
➢ Related DC connectors need to be purchased
separately for DC cables
➢ DC copper cables must be compliant to
ETSI EN 300 132-2 and relevant VFDE norms
➢ Maximal DC cable length allowed for
deployment:
➢ 450m with 2,5mm2 DC* cable
➢ Longer cable length* will be
available later if 4mm2 DC cable and
