Tasik Chini
Tasik Chini is the second largest fresh water lake in Malaysia. The lakeshores are inhabited by the Jakun branch of the Orang Asli (indigenous people).
The 12,565 acres (5,026 hectares) lake is made up of a series of 12 lakes. Sungai Chini, which drains from the lake, flows into Sungai Pahang.
Tasik Chini is one of the UNESCO Biosphere Reserve status sites in Malaysia.

Sample Measurements at Jemberau Station
Dissolved Oxygen (ODO) and Acidity (pH), Saturday, 15/10/2016 12:00 am
to 3:00 pm
GUIDELINE:
• 0-2 mg/L: not enough oxygen
to support life
• 2-4 mg/L: only a few fish and
aquatic insects can survive
• 4-7 mg/L: good for many
aquatic animals, low for cold
water fish
• 7-11 mg/L: very good for most
stream fish

RSS vs. Distance
• RSS for actual
measurement at Tasik
Chini and theoretical
propagation models is
given in this slide.
• NLoS propagation model
is based on Hata Model
for different gateway
(GW) and sensor node
(SN) height.
• Green diamond markers
and red square markers
represent the simulated
configuration for GW =
30m & SN = 10m, and
GW = 6m & SN = 2m,
respectively.

Summary
Ultimate aim
Provide IoT solution for environmental preservation (sensors, connectivity, middleware, analytics etc)
Challenges
Network Infrastructure & Connectivity – Propagation environment, vegetation effect, terrain, etc
Business Model– Community and environmental driven

Spectrum Measurement Results
Access in Band 450MHz (CDMA450) is also active. The CDMA 450 is characterized as having
Upper band: 462.090MHz to 466.360MHz and Lower band: 452.090MHz to 456.360MHz.
Furthermore, there is a need for MCMC to investigate why there is high power from 413MHz
to 422MHz. at 465 MHz. In the MCMC spectrum chart currently in use, the band 460—470
MHz is not allocated. However, a high signal was captured. Based on ITU regulations, this
band is reserved for Fixed Mobile or Meteorological-Satellite (Space-to-Earth). By this
information, we hope that MCMC is aware that satellite beams are transmitting using spectrum
band.
