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.
