8.3 INSTALLATION
Three styles of system installation are shown below. Of these, (a) has the lowest RF losses and the highest
efficiency of power supply to the RU. However, mounting of the battery equipment up the pole may be considered
a disadvantage from a mechanical or installation viewpoint. In (b), the RF losses are still low, but the DC power
losses are highest, whilst in (c) the DC losses are minimised, and access is convenient but at the expense of RF
performance. Option (b) may also be achieved using Power over Ethernet (PoE) which is described further in
section 8.2.3.9.
Typical pole and rack mounting options for the radio unit
Note: refer to section 8.2.6.1 for grounding and lightning protection considerations.
Regardless of the mounting configuration used, the appropriate site engineering must be undertaken. Site
engineering must consider safety aspects such as grounding and lightening protection but also needs to take
performance parameters such as antenna location, antenna separation and other RF sources. Please contact
Mimomax if more information in these areas is required.
A comprehensive source of information and guidance on general site engineering issues has been published by
ETSI: EG 200 053 v1.5.1, 2004/06 ‘Electromagnetic compatibility and Radio spectrum Matters (ERM); Radio site
engineering for radio equipment and systems’. It is highly recommended that this freely available ETSI document
be studied in detail, in conjunction with this manual.
