Background: The City of Ventura Public Safety Department (PSD) was in the process of upgrading the connectivity between it’s various geographical sites. The PSD had an existing network of data T-1 line through their telephony provider, Pacific Bell. The network consisted of 11 sites, including the connectivity between City Hall and the PSD Headquarters. The PSD was proposing that all existing T-1 telephony equipment and connections be upgraded at a proposed cost of approximately $90,000.00 plus. This did not include the recurring T-1 cost that would continue at $2,000 per month or $24,000.00 annually. The proposed project at a cost of $114,000.00 for the fiscal year was submitted to the City Council and approved.

first experimented with wireless network connectivity to allow students to access the Internet and the school network remotely from their laptops while working in the library. “We installed nine wireless antennas on our first floor and began supporting about 200 students,” said David Dickens, network services manager, Pepperdine University School of Law School. “At that time, wireless infrastructure was pretty new to the educational industry. We knew we wanted to enable our students to connect wirelessly for convenience and improved productivity, but we weren’t exactly certain how well received it would be and if it would prove mission critical to them.” Once the system was up and running, students began connecting to the system via their laptops as they walked around the building. “Students tried to use it vigorously at first because it was a source of convenience and it was something new,” Dickens added. “Within a very short period of time many of the students began to depend on it. Wireless connectivity became the norm for them. They spend three years of their life here. Our product is more than just their education; it’s their life.” As system use grew around the law school, the existing wireless infrastructure had challenges supporting all of the users. The school wanted to improve the system but lacked the in-house expertise. “We wanted to bring in wireless experts from the outside – someone who understood the technology, physical mechanics, and was well known with experience.”

Venture Technologies Group, LLC (Los Angeles, Calif.) BUSINESS CHALLENGE: From its home base in Los Angeles, CA, telecommunications company, Venture Technologies Group, LLC, owns and operates a variety of television stations nationwide. This TV broadcaster is able to keep its overhead low by using unlicensed 5.8 GHz radios, instead of the more common licensed analog microwave radios used by most broadcasters, to send program video from it’s studios to it’s transmitters. During the recent transition to DTV, Venture Technologies Group was approved for and built a digital station on Mt. Wilson, approximately 20 miles from its Wilshire studio. The company then faced the task of getting a signal to the Mt. Wilson transmitter. According to Daniel Bissett, Director of Engineering for Ventura Technologies Group, the Mt. Wilson station is the same distance from the studio as one of their other stations located on Mt. Harvard and only 1.5 miles to the side of the Mt. Harvard station. Because the company had what seemed like a reasonably good 5.8 GHz link between the studio and Mt. Harvard, the assumption was that the same type of equipment used for the Mt. Harvard link would work for the Mt. Wilson link as well. This assumption proved incorrect. Bissett stated that the 5.8 GHz link to the Mt. Harvard station has a fairly high bandwidth but there were issues with its alternating and varying latency, resulting from high local RF noise levels, that made the link unsuitable for sending actual video over it. At Mt. Wilson, the RF noise levels were so high, that the available bandwidth was reduced to almost nothing. Links to this site proved to be useless.
