Efficient Design and Analysis of Airborne Radomes
Aviat Networks Inc. is deploying its Aviat WTM 6000 all-IP trunking microwave radios for Telecom Fiji Ltd. (TFL), the island nation's sole provider of local and national telephony services. Linking the main islands of Viti Levu and Vanua Levu, Aviat Networks will design radio paths and install the high-capacity network for TFL.
In need of replacing an aging PDH radio network, Telecom Fiji required a high-capacity solution that would enable them to reliably deliver voice and data services to subscribers on the second largest island to the north, Vanua Levu. This included overcoming two very demanding paths of approximately 50 miles of mountainous terrain and the ocean between the islands. In addition, the replacement solution needed to be configured with the capability to eventually be migrated to an all-IP architecture.
The WTM 6000 complements the company’s Eclipse Packet Node radios already in TFL's network. Both will be managed by the ProVision element management system. The WTM 6000 will be upgraded for Ethernet traffic over time. Furthermore, the WTM 6000 links are preconfigured for an easy transition to a 7+1 operation with no planned disruptions during the process. In the long term, TFL's WTM 6000s can use built-in ‘over the air’ Layer-1 Link Aggregation (L1LA) to offer Ethernet capacity of 1,920 Mbps in an 8+0 configuration.
"With the most flexible capability of any TDM + IP trunking radio on the market, the WTM 6000's capacity can be varied by Telecom Fiji Limited to accommodate as much TDM and IP traffic as needed," said Shaun McFall, chief marketing officer and senior vice president, Aviat Networks. "As the TFL network evolves, the WTM 6000 will evolve with it. The WTM 6000 offers the easiest path for migrating from TDM to TDM + IP to full IP: the ultimate goal for the end of any network evolution."
