Telamon is providing an upstart Wireless Internet Service Provider (WISP) company full turn-key services to establish a market presence. There are many moving pieces involved in the market deployment that all take place in parallel.

1. Source Equipment

The first element to the project was sourcing equipment. Telamon Engineers and Project Planners worked with the customer to develop a Bill of Material (BOM) that would be suitable for the market roll-out. This process involved working with multiple vendors to obtain technical specifications, lead times and cost. The customer sourced some of the major material directly from the OEM, but most of the equipment and installation material was sourced through Telamon. This included outdoor cabinet enclosures that would house the radio gear, microwave dishes that ultimately are mounted to a tower in the market, and mounting hardware for the radio antennas and microwave dishes. Our customer also had a need for Customer Premise Equipment (CPE). This product is a wireless device used by end-customers to receive service from the tower over the air using the WiMax standard. Telamon worked with vendors in Europe and Asia to procure this material.

2. Engineering and Integration

Engineering and Integration is an important element for all of our projects. This serves as the foundation for all of the other stages that occur with a project. With this, Telamon met with the customer and multiple vendors to design: the equipment needed, how the product would be configured from an integration standpoint, how it would be installed, tested, and ultimately supported upon completion.

Telamon engineered a process to populate the outdoor cabinet with equipment from multiple manufacturers. The correct power requirements were taken into consideration when a fuse panel and battery back-up system were selected. Each piece was then integrated in our Carmel staging and integration location. During the Integration process, Telamon begins the configuration of the device. Specific IP addresses and system parameters are loaded onto the equipment before it is sent to the field for installation at the base of a tower.

3. Configuration and Testing

Telamon provided some configuration and testing during the integration, but the remainder is completed in the field. The configuration and testing performed on this project were actually done during the integration phase in our Carmel facility.

4. Field Survey and Installation

Prior to the start of the project, several Field Surveys were done. There were four locations in the market which all had unique factors Telamon took into consideration. Three of the locations were cellular towers, and one was a Data Center. The Data Center is the source of the internet backhaul that will feed the tower locations via a microwave link. To ensure that the link would work correctly, a field survey was done to verify the microwave path is available which determines equipment mounting heights.

In addition, more than one type of cellular tower was going to be used in the project. Some towers are mono-pole, and others have a frame structure. This was noted specifically in the field survey, because different mounting equipment is needed for each type of tower to mount the antennas correctly.

Another key element with this project was the site acquisition of each tower. Before installation can begin, an application process takes place with the tower owner. During this process, Telamon also negotiated a lease for space on the tower between the tower owner and the carrier. In this case, the carrier was Telamon’s customer. We acted on their behalf to secure the space on the tower and submit the application. At one of the locations, a building permit was required. Telamon also acted on behalf of the carrier to secure the building permit.

Once the applications were accepted and building permits were in place, the installation can begin. First, a civil crew visited each site to prepare the site for the cabinet. The civil crew installed a ground ring for each cabinet and a mounting platform/structure. AC power was run from the local electric utility meter to the cabinet.

Next, the tower crew arrives at the location. The tower crew installed the lines and antennas on the tower, in addition to mounting the equipment cabinet. Each tower received three antennas, one for each sector, enough to provide service to a 360 degree pattern around the tower. In addition to the antennas, which provide service to the end customer, microwave units were installed. The microwave units carried the backhaul internet signal from the data center in a daisy chain fashion, so some locations received two dishes while the third only had one.

5. Field Testing

After the installation was completed, the field testing was performed. To ensure the new equipment was working properly, Telamon tested the different elements that were installed. First, the microwave connections were tested. Upload and download tests were performed and compared against expected results. Some of the links were adjusted to optimize the performance and obtain the expected result.

To test the radio signals coming from the antennas, a specific type of test, called drive testing, was performed. Telamon used test gear specifically designed for testing radio signal strength. During the test, a Telamon engineer drove a specified route that was created. Values were taken along the route and plotted on a map against expected values based on geography and distance.

The final test performed was to actually test the signal using a wireless modem that a customer would have at their home. This test demonstrated that the new network actually worked in the setting requested by the customer.

6. Maintenance and Support

Telamon could also provide maintenance for this network; however it was not requested for this project. Telamon does however provide support as needed to diagnose any network issues and planning for future deployments.

7. Retire Equipment

Telamon did not retire any equipment as part of this project. However, Telamon does retire or remove equipment as requested by a customer.
