WI-SUN JUTA
ROHM is also developing products from the
standards formulation stage for Wi-SUN JUTA,
a new international wireless communications
protocol for battery-driven smart meters.
ROHM's wireless communication modules
have already been adopted by Tokyo Gas Co.,
Ltd. (Figure 4) and were the first in the industry
to obtain Wi-SUN Alliance certification as a
Certified Test Bed Unit (CTBU) for the new Wi-
SUN JUTA standard released in May 2019.
Wi-SUN JUTA Features:
1. Achieves ten-plus year operation with battery-
powered smart meters
Wi-SUN JUTA carries out intermittent operation
(always in sleep mode except when
sending/receiving signals at regular intervals) that
minimizes receiving time, making it possible to
reduce current consumption by more than 98% over
conventional Wi-SUN
