Abstract
IEEE currently doesn’t standardize usage of sub 1 GHz operation, such as the 900 MHz ISM band. While these bands are limited, they are attractive for outdoor usage.

Sub 1 GHz and IEEE
Current IEEE standard does not cover below 1 GHz, such as the MHz ISM band.
This band does have an advantage over 2.4 GHz, 3.65 GHz and 5 GHz because of range per transmit power.
Better free space propagation loss
Better clutter propagation loss. i.e. trees, telephone poles
Increase in battery life
A disadvantage is the limited bandwidth.
However sufficient for 5, 10 and 20 MHz OFDM
Down to 1.25 MHz wide channel also useful
Smaller channels also allow for bandwidth sharing

SmartGrid has a large outdoor component
Use IEEE !
Select band and channel width to meet the usage needs.

Use existing IEEE PHY for quick solutions
Solutions today with added down converter.
Possible future solutions similar to dual mode .11a/.11g WLAN cards.

6. Standardization effort
January 2010
Standardization effort
Standardization effort should be similar to IEEE y.
IEEE y PAR approved 3/16/2006
REVCOM Standards Board Approval 9/26/2008
Efforts within IEEE j, .11k, .11y and current .11m will make this effort easier provided not a new PHY.
Channelization
Annex I, J of
Channel width down to 1.25 MHz
Clause 17, 20
