Summary
Every wireless site requires a free-standing shelter or cabinet to secure network equipment. Equipment protection, power management, and power backup support are critical concerns when deploying electronics equipment in any setting.
Designed for indoor use, the active wireless components must be located on a site with environmental controls. A structure is required to ensure the equipment is protected from the elements—including heat, humidity and cold, as well as pests. Also, any cables running from the antennas to the equipment must be protected from falling ice that forms on towers.
FeatureS oF ShelterS
Secure environment for storing sensitive on-site equipment•
Large footprint provides room for deployment, room for •technicians to work indoor, and enables future expansion
Expensive to erect or install•
Can complicate lease provisions or zoning process•
FeatureS oF CaBinetS and enCloSureS
Capacity to secure most wireless equipment•
Numerous sizes to choose from based on location, •equipment requirements and future expansion
Small footprint allows for flexible deployments, often •reduces zoning and leasing difficulties, and enables equipment to be secured separately
Provides options for complete environmental controls •based on geographic or equipment requirements
Availability of all-in-one solutions that provide ample •equipment space, power management solutions, alarming and battery backup
real World exampleS
Situation: A Wireless Internet service provider (WISP) was co-locating their access points on a tower.
Problem: While there was a shelter on the site, the WISP was concerned about other co-locaters having access to his equipment in the shelter.
Solution: Locating an enclosure on a small grated platform enabled the WISP to secure their equipment on-site with temperature controlled conditions.
Situation: A utility company needed to mount a critical repeater to backhaul traffic from their network in a remote location where no shelter was available.
Problem: The hop required the indoor PIDU equipment to be sheltered and backed up for a minimum of 8 hours.
Solution: Locating a solution designed for point-to-point radios offered shelter for the indoor units and 48VDC power with 8 hours of backup for the entire site—in a pole mounted package.
Situation: A tier-one carrier needed to migrate service platforms from GSM to UMTS for 3G Service.
Problem: The number of cabinets allowed at the site was restricted.
Solution: Locating a larger cabinet that could house both GSM and UMTS equipment with battery backup and power distribution for both allowed for deployment within their restrictions.

Shelter Equipment & Power TIS Application Training
Customer Problem/Need Effects on Customer Solution Questions
Every site requires environmental protection for the active components in the network.
Customer can save money by installing their equipment in an existing shelter
Losing power is losing revenue because the network is down and someone needs to go fix it.
Components have shrunk to the point where they can be protected by a small inexpensive cabinet on a platform.
They still need numerous products to install the components (see At-A-Glance)
A battery backup system keeps the network up when site power goes out, providing enough time for a fix w/o losing uptime.
Customer is co-locating on an existing tower and is required to provide their own shelter.
Where are you installing the radios/ components on site? A
The utility power at the site has been failing too often and the customer has decided they need a battery
What does losing power do to your network?
What is the cost of network downtime?
B

While this site kitted method saves time, additional required products are forgotten for installation.
The customer needs to develop an installation plan and determine all required products before getting on site.
Customer is co-locating on a tower site, but the radio is outdoor rated (or comes with a cabinet)
How are you protecting the cable on site? Do you need a platform for the cabinet?

SETTING UP THE TIS INTERCHANGE
Obstacles to the Sale“My team gets how electric works”
“The radio is weatherized”
“I get my cabinets from someone else”
“I don’t need/can’t afford battery backup”
How to Overcome Today’s electronic radios are very sensitive, proper training ensures that your system is protected from expensive damages
REASON FOR THE CALL: Shelter is rarely the reason for a call to a customer. It is more likely to talk about shelter and site power equipment once you have uncovered the application, discussed radios, towers, cable, antennas, etc.
UPFRONT CONTRACT: “Now that we have determined your radio, cable, antenna, etc. solution, I would like to talk about how you are going to protect and power that equipment.”
SAMPLE DISCOVERY QUESTIONS: 1. Do you have an existing shelter on site? 2. What type of cabinet do you plan to use to protect the radio on site? 3. How are you going to power that radio? 4. Have you considered what happens when the site power goes down? 5. Have you tested your power components for proper operation? 6. Do you have all the tools you need to install on site? 7. Does your team have experience working with today’s sensitive electronic equipment?
Customer doesn’t need a cabinet, but look at the application drawing to find additional products they need.
Ask the customer to think about what happens when the network goes down? How much does that cost? Wouldn’t there be tremendous benefit to having an
extra 8 hours to fix it?
TESSCO understands radios and their subtle environmental requirements better than anyone else. Plus talk about savings of TESSCO being a Total Source
Buzzwords and Trends: 1. As technology develops equipment is getting smaller and smaller, resulting in outdoor rated cabinets
being more common than new shelter structures. 2. NEMA (National Electrical Manufacturer Association) is a rating system defining what types of
environments an enclosure can be used. The primary ratings used in wireless are: a. NEMA 3 – outdoor for protection against rain, sleet, windblown dust and protection from ice
formation b. NEMA 4 – indoor or outdoor use for protection against windblown dust and rain, hose directed
water and damage from external ice c. NEMA 4X – NEMA 4 plus corrosion protection d. NEMA 10 – meets MSHA requirements
3. Rack Unit (RU) – describes the height of a piece of equipment installed in racks (1.75”)

3rd PARTY STORIES BY APPLICATION & SEGMENT:
• SMU (Railroad) – Union Pacific was installing a new wireless backhaul site. There was an existing shelter on site, so they did not require an outdoor rated cabinet for the equipment. However, the existing shelter was out of RUs and a new rack, cable management and power equipment were required. The AM asked about the battery back up system and the customer determined that they need to increase the size of their system in order to support the new backhaul system. In addition, the AM inquired about training. The installer was a trained RF engineer, but was not an expert on electrical systems, uncovering a sale for a training module for the new engineer as well as a refresher for other engineers working in the field.
• Broadband – A VAR was installing a leased line point-to-point link between two office buildings for a client. Each link was to be installed on a roof top. Even though the VAR was installing outdoor rated radios and had access to the communications closet, they wanted to have access to the system 24/7/365 in case of a problem. A small outdoor wall cabinet on the roof solved the problem. In addition, the AM picked up the VARs desire to ensure uptime and suggested the LinkUPS system which provided 8 hours of backup as well as an outdoor rated cabinet to house the power supply and surge arrestors.
• SCADA (SMU, VAR, GOV) – A utility company called in for a ten 10’ tower sections, 10 yagis and 500 ft of cable with connectors. The AM inquired about the application for the products and found out that the utility was installing a small SCADA system to monitor electricity flow in a remote troubled area. The AM realized that there was additional opportunity and asked about how the utility was planning to power the radio (had power on site, but needed to step down the voltage) and house the equipment, leading to the sale of a voltage converter and small on outdoor cabinet.
• Cellular Install (CRR, PRM) – A contractor was co-locating for a carrier on an existing site. They called in for the standard equipment – including cable, connectors, etc. (see Towers & Monopoles application). The AM inquired about the site layout and determined that the contractor was installing an all-in-one BTS cabinet that only required a plug into utility power. However, the contractor did not have a platform to place the cabinet leading to a $4000 sale.
• Cellular Install (CRR, PRM) – A contractor was upgrading a site for a carrier installing on a tower with an existing shelter. Once they got on site, they realized there was no additional rack space and required a new rack and shelves, cable runway, AC surge arrestors and cable management supplies.
