RE: stds-80220-requirements: FW: 802.20 Requirements - Repeaters



Title: Message
Folk-
 
Lets remember we are writing a requirements document.  So to say "its manditory"  I understand this to mean,"the standard must define a protocol to handle a repeater function."    Further there is an assumption that this repeater function should be integrated with the "standard" protocol.  So the "standard" system will not know if  it is or is not talking to a repeater.

Hi Li,
 
Perhaps the requirement wording needs to indicate that the capability to support a repeater is mandatory, not that repeaters are mandatory.

Hi, everyone,

 

Below are my two-cents on the issue of the repeaters.

 

  1. The use of repeaters is a performance enhancement issue. In some situations, repeaters make sense. While in others, there are alternative ways as well. A mandatory requirement seems too strong.
  2. The impact on the AI is subject to investigation. It may be a little too early to conclude that the system has to support huge delay or delay spread.

 

Best,

 

Junyi Li

Joanne et al.,

 

Support for the use of repeaters needs to be a mandatory requirement because operators need to have this tool in their tool box to economically provide in-building coverage and in lightly populated areas.  If you recall from the presentation in Singapore that KTF uses allot more repeaters than base stations in their network. The same trend is also occurring in the US.

 

The impact on the AI is that the system has to support larger delay's and delay spreads.

John,

 

It's not clear to me the AI design implications of the changes you have made.  However,."should support" implies that

support for repeaters is optional.  Changing to "must not preclude" makes it a mandatory requirement.  This change,

at least to me, doesn't clarify the rationale so much as changes requirement itself.  I support maintaining the previous wording of the requirement until we have a better understanding of the implications of the change and the rationale for such.

 

Best regards,

 

Joanne

Current Text

Support for the use of Repeaters (Open)

The system should support the use of repeaters

Proposed Text

The AI must not preclude the use of repeaters or reflectors to bypass obstructions and extend cell coverage.

 

Rational

1) This text clarifies the rational given at the meeting in Singapore
