Ateneo – JRC - PLDT WIPAS Project

Wipas Project Report

26 GHz Wireless Technology Logs Greater Than 99.5% Availability During Rainy Period

The WIPAS Project, launched on April 2007, is an ongoing collaborative project between the Japan Radio Corporation, Ateneo-PLDT Advanced Network Testbed and the Philippine Long Distance Telephone Company.

A highly scalable proof-of-concept hybrid broadband wireless network is deployed with 26 GHz WIPAS (Wireless IP Access System) as its core technology in combination with 5 GHz transceivers from SMART. A 400 meter in-campus 26 GHz link was initially set up and monitored for two months from March to June of 2007. Subsequently a 4 km line of sight 26 GHz link from Ateneo to PLDT-Balara was deployed.

The system performance is measured with and without the presence of rain via the use of conventional tipping bucket rain gauges and new rain sensors based on the measurement of acoustic signals. Dropped packets and received signal levels are measured in real time and synchronously with rain rate sensor data. The testbed thus continuously monitors the performance of an advanced wireless broadband internet technology under Philippine climatic conditions. In addition, these measurements verify a novel and powerful approach to real-time disaster monitoring and management that is scalable to national and even regional dimensions.

To date, measurements over the 4 km link indicated precipitation induced fadeouts only 0.2% of the time (where the signal drops by 16 dB or more to below -80 dBm levels), and this over a fifty day span with several heavy rain events, indicating the maturity of this broadband wireless technology for Philippine tropical conditions. The project is still ongoing and the 4 km broadband wireless link is still continuously being monitored.

The facility is available for collaborating Ateneo faculty and student researchers as well as Japan Radio Co. and PLDT-SMART engineers for wireless systems and wireless sensor networks product and system research and development.

Japan Radio Corporation is a leading provider of wireless and radio-frequency solutions and systems for the global market for applications in communications, telemetry, logistics, shipping and weather monitoring.

The PLDT-Ateneo Advanced Network Testbed is an R&D cluster that brings together expertise from both PLDT and the Ateneo to test, evaluate, research and develop next generation technologies and systems solutions.

PLDT-SMART (Philippine Long Distance Telephone Company – SMART) is the leading telecommunications and services company in the Philippines with the most extensive fiber optic and mobile wireless communications backbone nationwide.
