Presented by Steve Lewey –Lake Washington School District 414

PROBLEMThe school district’s RF plant was failing and no longer supported digital signals to the rooms, Lake Washington needed an alternative way to deliver these feeds.

• Went to a classroom projector-based model of delivery of all visual resources over the classroom PC

• Did not want to provide a set-top unit in each classroom based on traditional RF infrastructure

• Did not want to support and maintain their present RF coax wiring

• Could not support their present coax cable plant

NETWORK CAPABILITIES

• Lake Washington’s high speed multicast network provided the bandwidth for delivery of their television station

• Provided the school with the ability to do school news not only in their school but across the district

• Provided the ability of one central location head-end for cable DTV across the whole district

• Provided a means for every district network jack to become an origination point for delivery of live stream

CHALLENGES• Cost to update RF presents 900 MHz

(non-directional I cable system too expensive)

• Coax was not designed to interface to our classroom model

• Traditional RF system did not support HD cable channels

• Finding support that understands RF design became a big problem

• Cable head-end at each building were expensive and hard to support
