WARNING: This equipment has been tested with a 19 dBi gain antenna and found to comply with the FCC guidelines for Radio Frequency Radiation Exposure Limits as detailed below. For a single base 5 watt transmitter connected to the antenna, a minimum of 2 meters or 6.5 feet of separation between the antenna and all persons must be maintained. The minimum separation increases when additional base transmitting signals are combined and applied to the same antenna. Four base 5 watt transmitters combined to use a single antenna need a minimum separation of 4 meters or 13 feet from all persons.

NOTE 1 TO TABLE 1: Occupational/controlled limits apply in situations in which persons are exposed as a consequence of their employment provided those persons are fully aware of the potential for exposure and can exercise control over their exposure.
Limits for occupational/controlled exposure also apply in situations when an individual is transient through a location where occupational/controlled limits apply provided he or she is made aware of the potential for exposure.
NOTE 2 TO TABLE 1: General population/uncontrolled exposures apply in situations in which the general public may be exposed, or in which persons that are exposed as a consequence of their employment may not be fully aware of the potential for exposure or can not exercise control over their exposure.
Note: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy, and, if not installed and used in accordance with the installation manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense.

INTRODUCTION TO BACKHAUL
INSTALLATIONS
Chapter overview
This chapter provides an overview of the Expedience system and of the system’s infrastructure components:
•The base station, which comes in two forms:
•The integral base transceiver station (I-BTS)
•The rackmount base station (RMB)
•The access provider (AP) server
•The network switches
The chapter provides an installation overview. It also describes things you need to consider before installing base stations.
System overview
This section provides a brief overview of the Expedience system, as well as the infrastructure that network access providers must install. For additional system overview information, refer to the guide “Getting Started with the Expedience System.”
System overview
NextNet Wireless designed the Expedience system to give small office, home office (SOHO), and residential subscribers high speed, wireless access to network communication systems, such as the Internet. The Expedience system is an end-to-end broadband wireless access system and operates in several frequency ranges.
The system was designed to allow network access providers to re-sell network bandwidth to ISPs on a wholesale basis. In turn, the ISPs sell access to their subscribers on a retail basis. To support multiple ISPs on the network, the system uses virtual LAN (VLAN) technology.
The system does not have a line-of-sight (LOS) requirement between the base station and the CPEs. The air link between base stations and CPEs functions as an Ethernet bridge carrying IP/ARP packets. Time division duplex (TDD) and cellular deployment offer you flexibility in adjusting downlink versus uplink airtime.
1-1
Infrastructure overview
The base station and AP server are network infrastructure components supplied by NextNet Wireless. The network access provider configures and maintains this equipment.
Additional infrastructure components include switches for use at the base station cell sites, and the head-end switch. These switches are supplied by the network access provider. If desired, the network access provider can purchase the switches through NextNet Wireless.
Base station overview
The base station maintains contact with CPEs at your subscribers’ sites. The base station integrates the transceiver and modem into one device.
Under typical configurations, the base station covers an approximate radius of 2 to 3 miles, with a 5 mile maximum. If desired, network access providers can configure their base stations to cover a maximum radius of 20 miles. To cover up to 20 miles, the network access provider enables the extended range feature.
There are two types of base stations offered by NextNet Wireless:
•An indoor-only base station that slides into a base station cabinet after the cabinet has been installed on a standard 19 inch rack. This base station is known as the rackmount base station (RMB).
•A base station that can be installed indoors or outdoors. This base station can be installed on a tower, on a roof, on a wall, or on a rack. The antenna can be installed on the base station itself, or the antenna can be installed separately. This base station is known as the integral base transceiver station (I-BTS).
Figure 1.1 shows an individual RMB which will be installed inside a cabinet. This cabinet is then installed on a standard 19 inch rack. Up to 8 RMBs can be installed inside a cabinet.

AP server overview
The AP server acts as a relay for the CPE registration events which arrive from base stations (on the management VLAN) and are forwarded to the correct ISP provisioning server (over the control VLAN).
The base stations each have a TCP/IP connection to the AP server. The base stations use their connection to forward CPE registration requests to the AP server.
The AP server is provided by NextNet Wireless.

Head-end switch, base station cell switch, and ISP switch overview
The network access provider must supply switches for their network, which include the headend switch and the switches used at the base station cell site. The network access provider must also assist their ISPs when the ISPs program their switches with the proper ISP VLAN IDs.
The base stations are grouped together into cells, with between 1 and 6 base stations at a cell site. (If the network access provider chooses to stack base stations, more than 6 base stations can exist in a cell.) To form the base station LAN, the base stations are connected to a switch at the cell site.
WAN links are then used to connect the cell sites to the head end switch. The head end switch splits incoming traffic to the management VLAN and to the appropriate ISP VLAN. The ISP then has a configured switch that controls traffic coming into and out of the ISP VLANs.
Installation overview
This section provides a high-level overview of how to install the indoor, rackmount base station (RMB), as well as the integral base transciever stations (I-BTS) that can be installed outdoors or indoors.
Installation steps common to RMB and I-BTS
1Plan the installation of base stations:
a Choose an appropriate location for the base station installation. For more information, refer to the section “Choosing an installation location” on page 1-7 in this chapter.
b Design the deployment of base stations. Determine how base stations will be deployed by marking a location on a map that shows where each base station will be installed. Also determine naming conventions for cells, sectors, zones, and base stations names. For more information, refer to the section, “Designing the deployment of base stations” on page 1-10.
2Plan for system components that you need to supply to complete the network. For more information, refer to the section “Assessing network access provider equipment needs” on page 1-8 in this chapter.
3Install and configure the access provider (AP) server. For more information, refer to Chapter 3, “Installing the AP server,” in this guide.
4On the AP server, configure zone names, VLAN IDs, and the ISP IDs. For more information, refer to Chapter 3, “Installing the AP server,” in this guide.
5Using the NextNet Operating System (NNOS), configure the base stations before deploying them in the field. For more information, refer to the chapter “Configuring base stations” in this guide.
RMB installation overview
This section provides a high-level overview of how to install the base station cabinet onto a 19 inch rack, and then how to install the base stations into the cabinet.
1Slide the metal base station cabinet into the 19 inch rack.
2Install the power supply onto the 19 inch rack.
1-5
3Install the switch onto the 19 inch rack.
4Slide each base station into the appropriate slot in the cabinet on the rack.
5If you are using a 5 watt base station, install the 5 watt channel specific filter.
6Plug in the cables which include:
•GPS cable
•Antenna cable
•Ethernet cables
•Power cables
•Alarm cables
Also, make sure that the fuses are installed properly.
7Plug in the power cable to the RMBs in the cabinet, make sure the power supply is working, then turn on each RMB.
I-BTS installation overview
This section provides a high-level overview of the base station installation process. Other sections in this guide then explain these installation tasks in detail.
The tasks you perform to deploy base stations are:
1Mount the base station at the site you selected. For more information, refer to the section “Mounting and grounding the base station” on page 6-57 in this guide.
2Connect the antenna to the base station, as described in the section “Connecting the antenna to the base station” on page 6-59.
3Mount the GPS device and connect it to the base station. One GPS device can service the multiple base stations at a cell site. For more information, refer to the section “Connecting the GPS equipment to a base station” on page 6-59 in this guide.
4Connect the base station to the transcient voltage suppressor (TVS) module, then connect the TVS module to your network switch.
The TVS module splits the connection: one connection goes to a switch that connects to your network, and the other goes to a power supply. For more information, refer to the section “Connecting to the backbone network” on page 6-60 in this guide.
5Power the base stations by connecting the TVS module to the power supply. For more information, refer to the section “Powering base stations” on page 6-61 in this guide.
6Configure cell site switches, the head end switch, and the ISP switches. For more information, refer to “Configuring switches” on page 2-12 in this guide.
7Test the network by working with an ISP to:
•Install the ISP’s provisioning server
•Test the AP server to provisioning server connection.
•Test that CPEs can access the ISP’s VLAN(s).

Planning the installation
This section describes issues you need to consider before you install the base stations, including:
•Choosing locations for the base station installation
•Planning for service provider equipment components
•Selection antennas
•Defining naming conventions for cells, sectors, and base stations and for VLANs
Choosing an installation location
The base station’s location at a site depends on many factors, including the site’s physical environment, the coverage pattern you want to achieve, and the ease of maintenance you require.
RMB installation location
The RMB is always installed indoors, inside the base station cabinet and on a standard 19 inch rack. In turn, the rack is installed in an indoor equipment room or in another type of indoor housing unit such as a shed near the tower.
1-7
BTS installation location
Table 1.1 describes some of the locations you might want to consider for a BTS.
Table 1.1 Advantages/disadvantages of location choices
Location |
Advantages |
Disadvantages |
On tower, at |
Installing at the antennas offers |
antennas |
cost savings, due to the fact that |
|
you can use a shorter coaxial cable |
|
to connect the base stations to your |
|
cells. This also offers the ability to |
|
transmit at higher power levels, |
|
since there is lower signal loss in |
|
shorter cables. |
When you install base stations near the top of the tower, installation and maintenance are more difficult.
At base of |
Placing the base stations at the base |

of a tower offers simpler |
|
installation and maintenance than a |
|
base station installed on the tower, |
|
at the antennas. |
|
Base station installation and |
|
maintenance are simpler than other |
|
options; |
If you install at the base of the tower, you need to run a coaxial cable from the base stations to the antennas. This cable must be of sufficient size to reduce signal loss, which may increase costs.
Installation still requires you to install the antennas and coaxial cable.
On rooftop |
You can use a shorter coaxial cable |
|
to connect base stations to |
|
antennas. As such, you can |
|
probably operate at higher power |
|
levels, and still stay within signal |
|
loss criteria. |
|
Rooftop access is usually available, |
|
making installation and |
|
maintenance easier. Also, a housing |
|
unit for the backbone network |
|
switch, power supplies, and other |
|
equipment is typically available. |
You need to obtain permission to use a rooftop, and comply with building codes.
Note: Regardless of the location you choose, plan to provide a weatherproof housing unit for the network switch, the power supply, and the TVS equipment.
Placement of base stations and switches on network
Make sure your network design places the base stations behind a switch so that the base station only sees Ethernet traffic addressed to it. The switch you choose needs to be able to handle the Ethernet traffic on your network
Assessing network access provider equipment needs
Before you install and deploy the base station, ensure you have made provisions for the following components:
•Power and data connection between the base station and your network
•Global position system (GPS) for proper TDD functions. You must use the GPS supplied with the Expedience system.
•Antenna system for transmitting and receiving signals for the base stations.
1-8 C o n f i g u r i n g , I n s t a l l i n g , a n d U s i n g C a r r i e r I n f r a s t r u c t u r e
•SNMP server
•DHCP server, if desired, to supply IP addresses to base stations
•AP server
•Weatherproof housing for the backbone network switch, power supplies, and UPS. Also supply weatherproof housing for the TVS module, which provides lightning protection.
•Coaxial cable to connect the base station to the antenna.
•Tower or building structure on which to mount cell site equipment.
Equipment needs of ISP
As a network access provider, you provide network bandwidth to ISPs. The ISPs in turn sell network access to subscribers. Make sure your ISPs plan for the following pieces of equipment on the ISP VLAN:
•DHCP server
•Customer care server and a customer relationship management application
•Provisioning server
•Switch to receive and direct traffic from the network access provider
•Router to route traffic to the Internet
Planning for the antennas and antenna installation tips
The type of antenna you choose depends on the cell type and pattern you want to use. Make sure:
•The antenna is a high-gain antenna, preferably at least 15dBi or higher.
•The installation of the antenna complies with the vendor’s installation directions, and that it meets building codes.
After you have installed an antenna, you need to connect it to a mounted base station. For instructions on connecting the antenna to a base station, refer to the section “Connecting the antenna to the base station” on page 6-59.
1-9
Designing the deployment of base stations
To plan for how base stations will be deployed:
1Determine a naming convention for base stations.
2Using a map of the area to be covered, define the zone names that will be used.
For example, an access provider can divide a metropolitan areas into North, South, East, West, and Central zones. The network access provider then assigns base stations to a specific zone by using the set system location command. Keep in mind that multiple base stations may be assigned to the same zone. Zones allow the ISPs to differentiate services to subscribers by allowing subscribers to operate in specific regions or clusters of zones.
3On a map, mark each location where base stations are installed.
4For each base station, document your design choices. Please note that some parameters are optional, depending on how you design the system.
•Base station name (required)

CONFIGURING NETWORK ARCHITECTURE
Chapter overview
This chapter describes a simple network topology. It provides an overview of how to configure switches at the cell site, the head end, and the ISP sites.
Architecture overview
The hierarchy of the network architecture uses the concept of two layers: the access layer and the backbone layer.
The functions of the access layer include connecting users — which include subscribers and the ISPs — to the backbone layer.
Subscribers use components on the access layer (the CPEs and the base stations) to obtain broadband network services. The subscriber’s CPE communicates with a base station over a radio link which is commonly called the air link. The base stations that communicate with the CPEs are grouped into cells. The base stations in each cell are connected to a switch at the cell site and a base station LAN is formed. The switches at the cell sites then use WAN links to connect to the head-end switch.
The ISPs also use the access layer to connect to the backbone layer. An ISP receives network access requests from components on the backbone layer (specifically the AP server on the management VLAN). These requests for access are sent to the appropriate ISP. The ISP then grants or denies the request. If access is granted, the ISP provides the subscriber’s host computer with an IP address and traffic is shaped for that host computer according to the subscriber’s service level agreement (SLA). Traffic to and from the host computer travels through the backbone layer
The functions of the backbone layer include quickly switching incoming WAN trunk traffic to the management VLAN and to the ISP VLANs. The backbone layer also returns Internet traffic from the ISP to the appropriate base station and subscriber’s CPE.
