Telecom Site Types - Slimline Masts/Guyed Poles
9 broad types of slimline masts or guyed poles
255 sites (28% of total sites)Operators encouraged to deploy slimline masts for RMA and communityreaction reasons.
Mast replacement typically required to enable co-location

Unacceptable Performance Degradation (UPD)
0.4dB NFE Formula calculation:
BS Receiver Noise Floor, NF-108.0dBm
External interference level, I(ext)-118.0dBm
-107.6dBm NFE = NF + I(ext) / NF = 0.4dB
-10.0dB

Effective BS receiver level has increased by0.4dB to -107.6dBm (so less sensitive)

Site Alterations - Key Comparators in Assessing theRelative Value of Site Alterations
Type Cost (est. ave.,excl AS’s own
costs)
Time (excludesequipment order time)
Short Term Impact RMA Approvalsrequired
Long Term Impact
Mast Extension $29,000
(plusstrengtheningcosts if required)
Design: within Full SiteApplication time
Build: shorter timeframe – extension plusnew antenna mount
Possible outage to all users toinstall
Existing positions on the mastmaintained
- Height (Ext only)
- Visual Impact
- incr RF output
In most cases can takeinto account otherusers’ forecasts
Mast Replacement $204,000 Design: within Full SiteApplication time
Build: longest – new
mast and move of allantenna
Definite outage to all users toinstall.
Existing positions on the mast
maintained
- Height
- Visual Impact
- incr RF output
Can take into accountall other users’forecasts
Antenna
Re-arrangement
$15,000 (APonly, excludesexisting users’scosts)
Design: within Full SiteApplication time, plusother ASs’ approval
Build: Shortest
New arrangement will needRF testing for all users.
Possible outage to all users toinstall.
Major impact on affectedparties
- Height (if re-arrangement putsantenna further up themast)
-Visual Impact
- incr RF output
No provision for futureforecast requirements,generally only of short-term benefit to oneparty
AntennaMinimisation
$54,000 (APcosts only,excludes existingusers’ costs)
Design: within Full SiteApplication time, plusother ASs’ approval.Likely to be longest toagree
Build: Medium
New antenna will need RFtesting for all users
Possible outage to all users toinstall.
Major impact on affectedparties
Forces technology change andpotentially significant de-optimisation for affectedparties
-Height (will changewith some newantenna)
-Visual Impact
- incr RF output
Mast already full, willgenerally only be ofbenefit to first in theQueue
No provision for futureforecast requirements,generally only of short-term benefit to oneparty
Note - the assessments in the table are generalisations, there will be variances between sites and Territorial Authorities
