Enclosure building practice

• Enclosure and door frame Work
• based upon aluminum profiles
• Walls, floor and roof
• based on multiple choices of sandwich panels
• Profiles and panel structure provide
• Complete enclosure dimension flexibility
• Extreme enclosure protection flexibility
• Low weight
• Flexible positioning of integrated equipment
• Exceptionally high stiffness strength

8
Enclosure building practice

• The dimension (W x L x D) of the enclosure is
  adjusted by cutting the profiles and panels to
  desired length
• A Corner joint supports the profiles and seals
  the corner so that it becomes waterproof
• The Corner joint can be integrated with lifting
  devices in the top of the enclosure

Case Description - SBE Nortel Case
FY04 Sales will be 8 M at 25 GP Existing
Outdoor Battery Solution from Hendry at 3000
per piece. (Double skin fans filter.) Henrik
Schubert (RSC) and Klas Hedberg (GSC) made a
study and presented a Solution from Emerson 2002
at a 30 lower price. Enabled by single skin,
Peltierinsulation-based solution. Nortel Calgary
bought in and we developed the Solution. Developme
nt cost was 500 k Manufactured in Ironton , USA

Case Description Orange Roadside
Orange had an APW Solutions with free ventilation
to suit 2kW 2G BTS. Now they needed higher
cooling capacity to include 3kW 3G BTS. We
quoted our High Capacity Solution against APW and
Invensys 2003. Invensys and our solutions were
tested and we won technically and on price. This
is our first GSP project win. Orange have
forecasted 500 pcs per annum which corresponds
to 2,5 M per year. Deliveries from Nove Mesto
will start in June - July 04.

Success Case MetroBox

• Claudio Maghini Case
• H3Gs problem was high cost of foot print in
  metropolitan areas combined with permits.
• The MetroBox have been approved by H3G and the
  first deliveries (5-10 units) are planned for in
  May.
• H3G choose the MetroBox because of the low visual
  impact (they can us the MetroBox in airports,
  train stations and densely populated areas) and
  the small foot print will save H3G 30 rent
  money for space.
• Value for MU IT is 1-2M/year for the next coming
  2-3 years.

• MetroBox is a new, easy, modular solution for
  mobile telecom application which allowed
  equipment housing
• MetroBox replaces outdoor cabinet independent of
  supplier and application
• MetroBox allowed telecom equipments in a small
  space, specially in urban area, for GSM/GPRS/UMTS
  (W-CDMA) application
• MetroBox allowed cabinet housing of Macro, Micro
  and Pico cell equipments, of remote radio units
  (RRU) and also of other main units
• MetroBox consents easy antennas installation
• MetroBox is equipped with energy power system,
  integrate cooling system, AC/DC distribution,
  batteries back-up, surge suppression, internal
  cabling and more accessories
• MetroBox is anti-vandalism cabinet for outdoor
  application
