courtyard, atrium, close, compound, court, enclosure, quadrangle,
square, patio or yard.
1.1.5
“Wireless LAN Security Guidelines” means guidelines issued by the
Authority for addressing security issues on WLAN.
1.1.6
“Wireless Local Area Network (WLAN)” means a network of connected equipments connected without the use of wires using IEEE
802.11 family of standards.
1.1.7
“Radio Local Area Network (RLAN)” means a subset of Wireless Access System outside Curtilage in portions of 5 GHz band.
1.1.8
“Indoor WLAN” means WLAN within Curtilage using IEEE 802.11 family of standards.

the Authority, upon request, a detailed history of all registered users
and their respective information.
The usage of indoor WLAN shall comply with the following requirements:
2.2.1
For Internet Access the Service shall be obtained from the Licensee offering Internet Service.
2.2.2
Use of Type Approved equipment.
2.2.3
