3. 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.

4. 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:

5. 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

26. 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.
