[DETAILED DESCRIPTION OF EDIT]
Change 'For the purpose of this document... by the MAC and PHY protocol
layers.' to:
For the purposes of this document, a "system" constitutes: an 802.16 MAC and
PHY implementation, in which at least one STS communicates with a BTS via a
radio air interface, and services transported by the MAC and PHY protocol
layers. In such a system, the BTS transmits information to the STS(s) via a
point-to-multipoint (PMP) channel and the STS(s) transmit(s) information to
the BTS via a shared channel, except in the case of a point-to-point
physical link where both channels are dedicated.
[REASON FOR EDIT
This change is meant to give a more accurate idea of what an 802.16 system
looks like.

change paragraph to:
A broadband wireless access (BWA) system based on 802.16 protocols is
expected to address markets similar to those addressed by existing wired
broadband access technologies such as:
· copper digital subscriber line (DSL) technologies;
· digital data over cable TV hybrid fiber/coax (HFC) networks;
· Integrated Services Digital Network (ISDN);
· aggregated telephony-oriented connections (e.g., T1, E1, ISDN-PRI etc.)
· the services that such networks carry: data, voice and audio/video [8].

terminology to be used by the 802.16 working group in the creation of the
standards.

[DETAILED DESCRIPTION OF EDIT]
replace paragraph with
As mentioned in section 1.1, an 802.16 "system" constitutes: an 802.16 MAC
and PHY implementation in which at least one STS communicates with a BTS via
a radio air interface, and services transported by the MAC and PHY protocol
layers. An 802.16 system employs point-to-multipoint (P-MP) forward path
radios links with carriers primarily centered in the vicinity of 30 GHz, or
more generally in the range from 10 GHz to 66 GHz, to connect a base
transceiver station (BTS) to one or more subscriber transceiver stations
(STS) [4][9]. The return path, STS to BTS, usually consists of a radio link
also within 10 GHz to 66 GHz that is shared between several STSs except for
when a point-to-point radio link is used for high bandwidth STSs. Radio
communications around 30 GHz require line-of-sight (LOS) between a BTS and
STS. Figure 2-1 and Figure 2-3 [13] depict some typical 802.16 systems.
802.16 systems are generally located within multiple-cell radio network,
i.e. multiple BTS coverage areas.
[REASON FOR EDIT]
- this is an informative section, requirements should not be present.
- clarity and removal of unnecessary verbage.

T
[DETAILED DESCRIPTION OF EDIT]
replace paragraph with
In general, within an 802.16 system, T the BTS radio transmits information
to the STS(s) via a point-to-multipoint (PMP) physical channel, and the
STS(s) radio transmit(s) information to the BTS via a shared physical
channel, except in the case of a point-to-point (PP) physical link where
both physical channels are PTP. In either case, the STS employs a highly
directional radio pointed at the BTS. Note that with this arrangement,
direct radio communications between subscriber stations is not possible.
Furthermore, the 802.16 system does not define radio communications between
base stations.
[REASON FOR EDIT]
- clarity of wording
- clarify description of an 802.16 system
- removal of requirements from this section (informative)
- co-location of radios in BTS is not relevant to this section or to the
interfaces being described in this standard.

delete lines 25 through 31 and make Bearer Services a complete section,
section 3.
[REASON FOR EDIT]
- with the other moving around, lines 25 through 31 are not required.
- the section on bearer services should follow the System Model section
because, with the other reordering of sections, by this point a clear
picture of what an 802.16 system exists and how the 802.16 protocols fit in
to that picture is clear. The bearer services section can now be made into
the first section of requirements.

types of networks that are able to interface with 802.16 based BWA networks.
