Discussion

1

Meets system requirements

How well does the proposed MAC protocol meet the requirements described in the current version of the 802.16.1 Functional Requirements? (See Document IEEE 802.16s-99/00)

2

Spectrum efficiency

Defined in terms of single sector capacity assuming all available spectrum is being utilized (either in terms of Gbps/Available Spectrum or in terms of Mbps/MHz)

3

Simplicity of implementation

How well does the proposed PHY allow for simple implementation or how does it leverage on existing technologies?

4

CPE cost optimization

How does the proposed PHY affect CPE cost?

5

Spectrum resource flexibility

Flexibility in the use of the frequency band (i.e., minimum frequency band required to operate and migration capabilities)

6

System diversity flexibility

How flexible is the proposed PHY to any other system variations and future technology improvements or new services?

7

Protocol Interfacing complexity

Interaction with other layers of the protocol, specifically MAC and NMS

8

Implication on other network interfaces

Intrinsic transport efficiency of telecomm and datacomm services

9

Reference system gain*

Sector coverage performance for a typical BWA deployment scenario (supply, reference system gain)

*In order to compare between PHY proposals, we define the reference system gain (RSG) as the output power of the transmitter minus the receiver threshold at a given working point, including back-off required for proper transmission. We will assume a 0 dBW transmitter (prior to back-off), and an ideal LNA (0 dB NF). Include BER working points of both 10^-6 and 10^-10 (post-coding).

10

Robustness to interference

Resistance to intra-system interference (i.e., frequency re-use) and external interference cause by other systems

11

Robustness to channel impairments

Rain fading, multipath, atmospheric effects
