Introduction

• The Egyptian Experience for the Mobile BTS safety
  codes has been realized by executing the Egyptian
  national project for auditing and monitoring for
  the mobile base stations.
• The project has begun since 2001
• The project is as a result of successful
  cooperation between the National
  Telecommunication Institute (NTI) and the
  National Telecommunication Regulation Authority
  (NTRA)
• The main objective of this project is to apply
  the certified protocols for both of the old
  installed base stations and newly ones.

Egyptian Safety Codes

• Three Protocols have been issued to regulate the
  installation of micro and macro sites, approved
  by 3 ministries
• -Communications Information Technology
• -Environment Affairs
• -Health and Population
• Macro, Micro, and IR safety guide lines have been
  issued based on the research studies that had
  been done by the Egyptian research groups from
  NTI and TRA and according to the international
  safety guide lines.
• The Egyptian safety codes may be summarized as
  follows

Summary of the Egyptian Safety Code 1- Macro BTS

• The Antenna heights (15m to 50m)
• 6 m in the main beam
• 2 m in the back beam
• The antenna is above the surrounding buildings in
  the radius of 10 m
• The Maximum Permissible Exposure (MPE) Limit is
  0.4 mW/cm2
• The antenna height of the pylon on the roof top
  is not less than 6 m
• The antenna must be fixed on the concrete
  structure roof top

6
2- Micro BTS

• The Antenna heights (not less than 2.5m)
• 0.5 m in the main beam
• Small gain antenna
• The MPE is 0.4 mW/cm2

7
3- IR

• The unit must be mounted on 3 m pole at the
  middle of the roof top or 6m pole for street
  mounted units
• the main beam must be directed completely to the
  outer space of the roof top
• The MPE is 1 mW for the aperture of 7 mm

• Poles on the boarder of the roof
• Pylon
• Penthouse
• Highway Towers
• Water Tanks
• Mobile BTS (Cell on wheels)

• Side arm patch
• Side arm omni
• Indoor
• Ceiling Mounted omni
• Wall mounted patch

Main Achievements

• Most of installed sites had been measured
• Establishment of re-auditing program
• Surveys cover all of the Governorates
• Measures about 100 sites per month

27
Conclusion

• Egypt has issued three protocols for Macro,
  Micro, IR sites.
• Issuing procedure for site acceptance certificate
• Continuosly revises re-measure of the installed
  sites. In order to check the current situation of
  the site.
• Updating of our protocols based on the experience
  gained from practical surveys and following new
  researches in this field.
