Wireless Stories:
| Client: | City of Atlantic Beach, FL |
| Problem: | Current Cisco 802.11 point to point equipment was dropping connections and was very slow. |

| Client: | Non-Profit Medical Supply Company in Brunswick, GA. |

| Solution: | Installed three Cisco 1230 access points using 60 degree sector antennas strategically placed in different areas of the warehouse. Original design called for four access points but upon installation found three covered 100% of the desired area. Installed fourth access point in a conference room to provide for internet access for guests. |
| Client: | Orlando Resort Management Company |
| Problem: | Connect the companies four locations to their data center. 3 buildings are within 2 miles of each other, the 4th building was 11.5 miles away. |
| Solution: | Installed four Redline Communications AN50 links. Two of the links are within two miles of each other and are line of sight. The third link was a 2 mile link bouncing the signal of a local hotel. The fourth link was a resort 11.5 miles away. The link was non-line of sight shooting across Disney's Epcot. All links are transmitting at the full 18MB rate that was purchased with latency less than 10ms. |
| Client: | Local FL. College |
| Problem: | Connect the schools network to a temporary building housing several classrooms that is across a busy street. |
| Solution: | Installed an Enterasys 802.11b point to point link that provided a secure connection to the schools network. Also installed another wireless access point inside the temporary building to provide workgroup coverage for the students and teachers. |
| Client: | K-12 School |
| Problem: | How to connect 3 separate buildings to the campus network at the least possible cost. |
| Solution: | Since the underground conduit was not usable, we decided to run 6-strand aerial fiber from the main MDF in the computer room to the gym and then onto the Athletic building. From the athletic building we used 802.11b wireless in a point-to-point configuration to connect to the maintenance office across the football field. This scenario provided the highest throughput and the lowest cost to the buildings that had the greatest number of users. |
| Client: | Hotel |
| Problem: | Need to provide high speed Internet access to the conference rooms for meetings and conventions. |
| Solution: | We installed a small switch between the main router and the internal firewalled network. From the switch, we uplinked to another router and then to a 24 port 10/100 switch that feeds all the CAT 5 jacks in the conference rooms. The conference room router provides NAT for the private network and DHCP services to all computers connected to the conference room network. |
| Client: | Hotel |
| Problem: | How to connect 3 PC's to the network that exceeded CAT 5 cable specs. |
| Solution: | Installed a wireless 802.11b network. We mount the access point and antenna in the restaurant which faces interior to the buildings where the PC's where located. We used a high gain 8db omni antenna to better penetrate the walls of the hotel. We then installed wireless network cards in the PC's and added a small antenna to one PC which was receiving a weak signal. |
