Draft Agreement

Agreement between US and AN Other on the deployment of Point-to-Multipoint Equipment in the (3.5 GHz and) 28GHz frequency bands in Britain.

In the following agreement the term adjacent channel refers to any channel that is transmitted or received wholly or partly within the following spectrum:

(3.5 GHz Adjacent block edge minus the 2 times the equipment channel bandwidth )

28 GHz Adjacent block edge minus the 2 times the equipment channel bandwidth

In the following agreement the term guard band refers to the following spectrum:

(3.5 GHz Adjacent block edge minus [2] MHz)

28 GHz Adjacent block edge minus [3.5] MHz

We hereby mutually agree to:

1. Without prior agreement, transmit on any channel where the channel bandwidth is wholly or partly within the guard band.
2. Without prior agreement, transmit on an adjacent channel an Effective Isotropic Radiated Power (EIRP) of greater than [50] dBm.
3. Restrict the out of block emissions into the other operators block according to the following table(s):

For 3.5 GHz

Frequency Separation from Block Edge (MHz)	Power Density relative to Carrier Power (dBc)
[2]	[-50]

 

For 28 GHz

Frequency Separation from Block Edge (MHz)	Power Density relative to Carrier Power (dBc)
[3.5]	[-50]

 

4. Within [6] months of deployment in a particular region inform the other of the type of any equipment that will be deployed in adjacent channels. This information will include:
   Standards complied to

Channel Bandwidth (effective and 3 dB)

Channel Power (Effective Isotropic Radiated Power)

OOB emissions

Maximum acceptable interference power

Any other parameters pertinent to interference protection

5. Within [3] months of deployment in a particular town inform the other of the location of any sector of a BS that is planned to use an adjacent channel. The information provided will include:

Co-ordinates of BS

Height of Sector

Azimuth of Sector

3dB Beamwidth of Sector

Maximum EIRP of Channel

6. Without prior agreement, deploy equipment in an adjacent channel that does not comply with one of the following ETSI standards:

3.5 GHz:
EN 301 021
EN 301 080
EN 301 124
EN 301 253

28 GHz:
EN 301 213-1
EN 301 213-2
EN 301 213-3

7. Without prior agreement, only deploy the following polarisation’s on adjacent channels:

US: Vertical

AN Other: Horizontal

8. In the event of that an operational problem is identified in the operational network that is caused by interference from the other operator the instigate the following procedure:

(i) The interfering operator should be informed in writing of the problem. Such information that is required to define and identify the cause and impact of the problem should also be provided.

(ii) Within [3] weeks of receipt of this information the interfering operator should arrange a meeting with suitably qualified personnel from each operator to discuss potential solutions and agree an action plan to resolve the problem.

(iii) If no agreed action plan then the matter will be referred to an independent arbitrator who will decide on a course of action (RA? is this really possible??)
