AISG Privacy Policy
The old AISG suffered a data breach a little while ago, so we are redesigning it to be safer.
As part of that migration, all old users have been transferred to the new site (not yet published).
Unfortunately, by mistake, that meant that all users received an email asking them to activate their account. Please disregard this.
However, within a week or two, you can expect another email informing you that the site is up again.
The Antenna Interface Standards Group (AISG) creates and maintains standards for the control and monitoring interface between a base station and a variety of tower-top equipment. These include antennas with remote electrical tilt (RET), tower mounted amplifiers and a variety of sensors that are used to monitor the operation of tower-top equipment. These are referred to as subunits. A complete list of those currently supported can be found here.
The standards include alternative PHY layers, an RS-485 bus and an OOK system using an MF radio-frequency signal transmitted within the coaxial cables joining antennas, amplifiers and base stations.
The latest version of the standards (v3.0) provides for devices with multiple control ports that may each be connected to different controllers (usually base stations), as well as the ability for the controller to map the RF system interconnections between devices connected to the bus. The standard comprises the base standard together with standards for each subunit type.
Membership of AISG is open to the manufacturers and users of equipment that implements AISG standards.
On January 31, 2022, new versions of the Base, ADB, RET and TMA standards were released as well as the first version of ALS. For details, please refer to the standards page.
AISG has started to develop a new standard for antenna sensors with the following capabilities:
This will be a part of the AISG v3.0 standard family.
AISG welcomes any member who would like to
participate in the development of this standard. Please email:
The AISGv3.0 standard were released on November 5, 2018. The current versions can be found on the standards page.

The AISG standard uses a Vendor Code as a part of a unique identity for all antenna line products. If your company manufactures antenna line products please contact the secretariat for information about recieving your unique Vendor ID and joining AISG. You can view a list of all vendor codes here.
This is a list of currently specified AISG v2 device types.
