Practical Challenges of Deploying WiMAX, WiFi and VSAT Technology in the Pacific.
Nauru Tender Process
|
Broadband Solutions Pty.Ltd (backed by SpeedCast, part of AsiaSat), won the tender to supply 13,000 people of the Republic of Nauru with internet and voice services.
Oceanic designed and implemented a hybrid WiMAX, WiFi, VSAT and solar/wind-powered network that provides local and international voice and data services at broadband speeds to the local community, Government and businesses of Nauru.
This unique fully solar/wind solution incorporates mobile WiFi voice telephony using handsets that seamlessly hand-off from one outdoor access point to another.

Nauru Technical Solution
- High-capacity satellite link to provide the highest efficiency available, in data transfer.
- WiMAX backbone throughout the Island.
- WiFi network covering most of the residential and business area.
- Entire network, other than the Command Centre, is powered by a solar-wind solution.
- VLANs, VPNs, CCTV, IP-PBX and IPTV services are handled by WiMAX overlay and connect schools, businesses and Government offices together.
|
Implementation
- Crane and cherry picker lifting was necessary to locate the WiMAX base stations at the various sites.
- Health and safety was paramount in this difficult, high-humidity and salt air environment
- Safety harness and fall arrests were used by riggers at all times.
- A number of WiMAX base stations and omni directional antennas were used at key tower sites. In some cases, they were connected directly to WiFi access point.

Nauru Installation Issues and Resolutions
- Sea freight delivery.
- On-Island inventory consolidation.
- Transport logistics.
- Project management leadership.
- 4-wheel drive vehicles access was not possible at all base stations.
- Unsafe existing towers.
- Porous rocks and NLOS to clients really put the WiMAX product to the test.
- Solar and wind power issues.
- Local 240 Volt power outages and no backup generator.
- Four months of project planning – 3 weeks installation.
- Extensive pre-stage, testing and configuration in Australia.
- Co-ordination of the 11KVA mains outages and pole installation.
|
Local Training and Participation
- Oceanic prides itself on training and engaging the local technical staff to work as a team to help build the network.
- This method of working assisted their understanding of the design and implementation of the network.
- It allowed our installation team to develop strong relationship with the local technical staff, creating a sense of local “ownership” which instilled a sense of pride and achievement which will cement commitment to on-going local network maintenance.

Local Public Access
|
Initially 35 poles were placed above the existing power poles to cover 70% of the Island. These units were fully self-powered. The WiMAX backhaul and WiFi access points were coupled together in one unique solution.
The first phone call on the VOIP network was made by a local Chinese restaurant owner who called mainland China to wish his family well. He was amazed at the voice quality!
He can now top up his pre-pay voice service using the Oceanic on-line voice billing platform.
