Portable VSAT Does WiMAX
Posted by Sam Churchill on October 16th, 2008“Satellite-enabled WiMAX is a strategic extension of our core capabilities,” said Dr. Amiee Chan, president and CEO, of Norsat, a leading provider of portable satellite systems.
Norsat plans to leverage its satellite communication expertise and work with telecommunications operators and other partners to provide end-to-end satellite-enabled WiMAX networks for voice, data and video. These solutions are expected to include: base stations, voice, data and video content servers, operations support systems, satellite backhaul solutions and satellite capacity.
“We believe by partnering with players in the WiMAX space, we will be well positioned to establish a strong foothold in this burgeoning market,” explained Chan.
“Approximately 3 billion people now use mobile phones, but only 400 million have a high speed internet connection,” Dr. Chan added. “We believe the launch of this business unit will introduce new revenue streams, help drive our push into the commercial market segment and further extend our global reach.”
The Washington Post asks, Is The Timing Right for WiMax? Yes and No.
In related news, the Department of Defense this week is hosting a demonstration of sustainable and renewable energy options for disaster relief and humanitarian assistance.
The project is called STAR-TIDES (Sustainable Technologies, Accelerated Research-Transportable Infrastructures for Development and Emergency Support). The idea is to pull together cheap and effective solutions for humanitarian emergencies or post-war reconstruction.
Their solution looks like two 40 watt Polycrystalline panels (80 watts at $600) plus a 200 watt wind turbine ($700). The panels might deliver a total of 5 amps for an average of 4 hrs per day, or 20 amp/hours total. That should charge a 45 amp/hr Optima Yellow Top 12 volt battery ($200) about half-way. A mobile router (WiFi locally/WiMAX backhaul) draws about 1 amp at 12 volts. It would discharge the battery about half way (operating 24 hrs/day). The wind turbine provides backup. The whole thing might cost around $2000.
A $150 Motorola CPEi 150 WiMAX modem (below, left) utilized Portland’s WiMAX network this summer. It connected to a a $200 Meraki outdoor WiFi access point (below right). A modified Power Over Ethernet system (12-24 volts is used on the Meraki instead of the standard 48 volts), which made the system even simpler to assemble.
Mike Boyd spliced the 12 volts (powering the WiMAX modem) onto the CAT-5 cable that connected and powered the 200mW Outdoor Meraki. Bingo. The two devices (combined) drew a remarkably low .7 amps at 12 volts. A car battery might have run it continuously for two days.
