C 1 H A P T E R 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 base transceiver station (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.
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.
Figure 1.2 shows 8 RMBs installed inside the base station cabinet. Figure 1.
Figure 1.3 shows a base station that can be installed outdoors or indoors The figure shows the antenna installed on the base station. If desired, you can install the antenna separately from the base station. Figure 1.3 Base station for indoor or outdoor installation 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).
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.
• GPS cables • Antenna cables • Ethernet cables • Power cables • Alarm cables Also, make sure that the fuses are installed properly. 7 Plug in the power cable to the RMBs in the cabinet, make sure the power supply is working, then turn on each RMB. 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.
• Defining naming conventions for cells, sectors, base stations and 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.
Cable loss ranges Use tables Table 1.2 and Table 1.3 to determine the cable size you need, based on signal loss. Table 1.2 Recommended cable length ranges for 2.3 - 2.7 GHz Length of cable drop Cable type Signal loss per 100 feet Signal loss range 4 ft to 85 ft 50 ft to 110 ft 90 ft to 150 ft 125 ft to 200 ft 1/2 inch LDF 5/8 inch LDF 7/8 inch LDF 1 1/4 inch LDF 3.52 2.65 2.02 1.47 .14 to 2.99 1.33 to 2.92 1.82 to 3.03 1.84 to 2.94 Table 1.3 Recommended cable length ranges for 3.3 - 3.
• 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 provides an appropriate pattern for the application, with uptilt and downtilt as required.

C 2 H A P T E R 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.
Configuring switches This section describes configuration of the following switches: • Switch connecting base stations at the cell site • Head end switch • ISP switch Configuring the switch at the cell site At the cell site, the network access provider must program a port on the switch to be a WAN trunk to the head end switch. Configuring the head end switch WAN trunk ports on the head end switch must be configured to accept traffic from the cell sites.
C 3 H A P T E R CONFIGURING THE AP SERVER Chapter overview This chapter describes how to configure and use the access provider (AP) server. AP server overview All base stations connect to the AP server using a TCP/IP session. Using this connection, the base stations transfer incoming registration requests from CPEs to the AP server. The AP server forwards the request to the proper provisioning server for authorization.
Configuring the AP server To configure the AP server, you must define AP server users, configure zone names, VLAN IDs, ISP names, and ISP IDs. Defining AP server users and administrators To define users and administrators of the AP server: 1 Open a web browser. In the browser’s address field, type the address of the AP server.

C 4 H A P T E R CONFIGURING A STANDBY AP SERVER Chapter overview This chapter describes how to configure a standby AP server. The network will use the standby server if the primary server becomes unavailable. Standby AP server overview The standby AP server can be put into service if the primary AP server is not available. Note: Make sure that the primary and secondary server are not running at the same time.
2 To save the changes to Flash memory, type the following: write 3 To make sure the setting is correct, type: show aaa The following information appears: aaa authority => remote aaa cache => enabled aaa port => 12541 aaa server address => 000.111.222.333 999.888.777.666 Note: 000.111.222.333 999.888.777.666 represent the IP addresses of the primary and secondary AP server respectively.
This user should be a member of the group users. The user name and password must match the user account and password on the ConfigServer. 4 Install the AP server using the standard installation program. When the installation program prompts you: a Place the NextNetHomedirectory on a local drive. b Specify that the NextNetConfigFolder resides on the remote share.
1 Stop the primary AP server. To do so, from a command prompt on the primary AP server, type: net stop Tomcat 2 Start the secondary AP server. To do so, from a command prompt on the secondary AP server, type: net start Tomcat After the primary server is stopped, each base station automatically detects the loss of the primary connection. The base station then attempts to connect with the secondary AP server. The secondary server connects to the ISP provisioning servers.
C 5 H A P T E R CONFIGURING BASE STATIONS Chapter overview This chapter describes how to configure base stations.
Setting up connection methods used to configure base stations The Expedience system allows you to connect to a base station using many methods: • Terminal emulation over a serial line • Telnet • Web server • SNMP server Before you can use a particular method to connect to the base station, you must configure its connection. To configure the base station initially, you will most likely use a serial connection and a terminal emulation session.
3 To set the IP address, or range of IP addresses, of the remote computers that are allowed to use Telnet to access the base station: {IPaddress | IPaddress mask} set telnet remote where: IPaddress is the IP address of the computer that is allowed to use Telnet to access the base station. IPaddress mask is a mask for a range IP addresses that are allowed to use Telnet to access the base station.
set snmp state enabled 2 To specify the IP address of the remote computer or computers allowed to access the SNMP server on the base station, specify a mask appropriate to your network. Type the following command: set snmp remote {IPaddress | IPaddress mask} where: IPaddress is the address of the remote machine that is allowed to access the SNMP server. IPaddress mask is a mask for a range of all IP addresses that are allowed to access the base station’s SNMP server.
6 Specify the SNMP community name. A community is a logical relationship between an SNMP agent and one or more SNMP managers. The community has a name, and all members of a community have the same access privileges. To specify the community that will have read privileges: set snmp read community {name} To specify the community that will have write privileges: set snmp write community {name} For both parameters, {name} specifies the name of the community.
For more information about these configuration parameters, as well as a full list of configuration parameters, refer to the guide “Using the NextNet Operating System.” 2 After setting the parameters, use the write command to write the settings into the flash, non-volatile memory. 3 For changes to take effect, perform one of the following: • Re-boot the base station —OR— • Power down the base station, and then re-power it.
5 watt base station Specify a power value from 6 to 31. The maximum system power level is 6, which specifies +37 dBm (5 watts) at the RF connector. The other power levels are measured in 1 dB down steps from the maximum. To operate the base station at the 5 watt level, you must install a supplied channel filter. Example: set airlink downlink power 10 Table 5.2 Transmit power levels Power value Power level 6 7 8 9 10 . . 13 . . 16 . . 23 . . 31 +37 dBm = 5 watts +36 dBm = 4.0 watts +35 dBm = 3.
Table 5.3 describes the downlink rates for various modulation methods for 6 MHz channel bandwidths. Table 5.3 Downlink rate based on modulation method 4-QAM Bias 0 1 2 3 4 5 16-QAM Downlink rate 1,337,358 1,719,413 2,127,308 2,294,515 2,424,466 2,530,766 Downlink rate 2,100,580 2,975,037 3,906,987 4,288,741 4,587,929 4,828,640 64-QAM Downlink rate 2,863,803 4,230,661 5,686,667 6,282,967 6,750,392 7,126,514 16-QAM lite Downlink rate 3,627,025 5,486,284 7,466,347 ------- Table 5.

During the design of the network, the access provider defines zones of coverage for the network.
Recommended parameter changes Before deploying a base station, it is recommended that you assign the base station a cell name and a sector name. set system cell This parameter specifies the cell name in which the base station is installed. Example: set system cell RiverBendRoad set system sector This parameter specifies the sector in which the base station is installed.
Setting up Syslog This section describes how to set up Syslog options. Syslog is a tool that records operational data, unusual system occurrences, system commands, and messages. To set up your system’s Syslog options: 1 To enable Syslog, use a command line interface run over the network (such as telnet) or use a serial line connection to the base station.
5 Set the Syslog server to the address of the network management workstation set syslog server {IPaddress} where {IPaddress} is the address of the workstation that is running the Syslog application. 6 To verify the operation of Syslog, open the Syslog server, where you can view messages or create Syslog message reports.
1 Contact the appropriate ISP to make sure the provisioning server hardware and software are properly installed. 2 Add appropriate routes to the base station’s routing table. Use the NNOS “route add” command to add a route (from the base station to the AP server), and a reverse route (from the AP server to the base station) to the base station’s route table. Note: Steps 3 through 6 help you configure the base station to use the AP server as a relay for CPE registration requests.
4 Reboot the base station. When the CPEs re-register with the base station, the base station places them on the legacy VLAN. Configuring the time signal used by base stations Expedience base stations require a time synchronization signal in order to determine the proper timing for time division duplexing (TDD).
1 Connect all base stations in your cell to each other, in a daisy chain manner. 2 Supply power to the entire system, as described in the section,“Powering base stations” on page 6-61 in this guide. 3 Configure the single base station or the master base stations to use an internal time synchronization signal: set airlink timing internal 4 Disable the set airlink afc parameter.

C 6 H A P T E R INSTALLING THE INTEGRAL BASE TRANSCEIVER STATION Chapter overview This chapter describes how to install the integral base transceiver station (BTS). The base station enables you to install the base station and the antenna as one item, which could save tower rental costs. You can also install the base station and antenna separately, if desired.
Cell wiring Figure 6.1 shows how a cell, base stations, and ancillary equipment are wired together. Figure 6.
Installation overview To install a base station as a single unit: 1 Attach the straight end of the antenna cable to the antenna connector on the base station and tighten. Apply weatherproofing tape to the connector. 2 If you want to install the base station and antenna as a single unit, use the antenna bracket integral base kit (part number 123-0350-1002) to attach the necessary brackets to the base station and antenna. a Determine the degree of tilt you need.
Installing the antenna and base station as a single unit Figure 6.2 provides an overview of the assembly. Specific assembly illustrations accompany the detailed installation steps in the sections that follow. Figure 6.
Attaching antenna cable to base station To attach the antenna cable to the base station: 1 Attach the straight end of the antenna cable to the filter on the base station. 2 Apply weather proofing tape to the connector. Figure 6.3 Attaching antenna cable to base station Note: For further information about the antenna connection, refer to “Connecting the antenna to the base station” on page 6-73 in this chapter. Determining the degree of tilt for the antenna You can tilt the antenna downward or upward.
The brackets illustrated in Figure 6.4 help to alter the antenna tilt.
Figure 6.
Attaching lower antenna brackets to bolts on lower sides of antenna Attach the antenna brackets to the bolts on the left and right side of the antenna (Figure 6.5). You must attach these brackets to the antenna bolts before attaching the brackets to the base station. Attach the bracket to the rear set of bolts on the antenna. The front bolts are NOT used when installing the antenna onto the base station. Figure 6.
2 Attach the antenna bracket (MP4) to the L-shaped bracket (see Figure 6.7) To tilt the antenna upward by 2 degrees, use the top set of holes to attach the antenna bracket to the L-shaped bracket. Figure 6.7 Attaching antenna bracket to the L-shape bracket MP4 Top holes provide 2 degrees antenna uptilt 3 Attach the tilt guide bracket to the bracket on the antenna (see Figure 6.8): a Align the holes on the side of the bracket with the holes on either side of the antenna’s bracket.
Figure 6.
5 Attach the antenna brackets to the bottom left and right sides of the base station. If you want to tilt the antenna upward, use the middle or lower holes on the bracket. • The second set of holes tilts the antenna 2 degrees upward. • The third set of hole provides an additional 2 degrees of uptilt. Figure 6.
c Make sure the area above and below the location where you want to install the base station has a good distance for clearance. This clearance allows for proper air circulation and heat flow from the heat sink fins on the back of the base station. The clearance also allows for the coaxial cable and the other cable connections. 2 Drill mounting holes into the surface, according to the dimensions shown in Figure 6.11. Figure 6.11 Base station mounting template 13.00" 10.
Figure 6.12 shows an overview of how to attach the BTS to the pole mounting bracket. Figure 6.12 Overview of entire BTS pole mounting bracket assembly To mount the base station on a tower: 1 Attach the pole mounting bracket to the base station and to the pole. 2 Install the pole and attached base station onto the tower.
Attaching mounting clamps to base station and around pole The pole mounting kit (part number 123-0350-1010) contains the hardware needed to mount the base station to a pole. • 2 front clamps (MP2) • 2 back clamps (MP1) • 4 threaded rods • 4 large flat washers • 4 small flat washers • 4 large lock washers • 4 small lock washers • 4 nuts In addition to this hardware, you also use the 4 bolts that are pre-installed in the base station’s 4 legs (2 at top corners, 2 at bottom corners).
2 Slip a small flat washer and small lock washer on the end of each bolt, then loosely re- install the bolts into the 4 corners of the base station. Note: Do NOT tighten the bolts into the base station fully. You will tighten the bolts in step 4, after you have hung the bolts, and therefore the attached base station, in the slots of the top mounting clamp. 3 Install the top mounting clamps (brackets) around the pole Figure 6.
b Insert the threaded end of the rod through the corresponding opening on the MP1 clamp. Figure 6.15 Threaded rod assembly, top clamp Step 3a Step 3b Step 3c c Assemble a large washer, large lock washer and nut around the threaded end of the rod. Tighten the nut. 4 Hang the base station on the TOP clamp, using the slots in the MP2 clamp. Figure 6.
5 To install the bottom mounting brackets around the pole: a Repeat steps 3a through 3c for the bottom set of clamps, threaded bolts, washers, lock washers and nuts. Note: To more easily shimmy the bottom bracket up the pole, fully install the left-most threaded bolt, but leave the right most bolt loose. Once the bracket is in place, slide the bolt through the side slot opening, then tighten the bolt using the washer, lock washer and bolt.
Mounting the base station to a 19 inch rack Base stations can be mounted to a 19 inch relay rack. Typically, NextNet Wireless stages this rack for customers as a service. Figure 6.17 Base stations installed on rack After staging, the base stations are mounted in the rack and wired to the TVS modules, the power supply, the backbone switch, and grounding plate.
If you desire to stage your own relay rack, you must use two 19 inch brackets (part number 350-0100-0101) and at least one grounding plate (part number 30-0100-0020). Base station connectors Figure 6.18 shows the connectors that the base station supports. Figure 6.
Figure 6.19 shows the Ethernet and power connector which plugs into the TVS module. Figure 6.19 Ethernet (data) and power connector 1 7 2 6 8 3 5 4 The connector to the base station has 13 pins. Figure 6.20 Ethernet (data) and power connector 1 2 10 11 9 3 8 13 4 7 6 5 12 Ethernet/power connecting cable Depending on your needs, you can order any of the following cables to connect the base station to the TVS module. Table 6.
Table 6.1 Ethernet/power base station cable choices Cable part number Length (feet) 597-6027-0050 597-6027-0100 597-6027-0200 597-6027-0300 50 100 200 300 Table 6.2 describes the pins of the Ethernet/power cable that connects the base station to the TVS device. Table 6.
Base station to TVS connector The base station connector supplies power and an Ethernet connection to the base station. Connect cable 597-6027-0xxx to this side of the TVS module. Figure 6.21 TVS module connector: Base station connector ISP ETHERNET +48VDC POWER +Note: Use the AUX +48 VDC and AUX ETHERNET connections only if you need to cut off the circular connector from the power/Ethernet cable (597-6013-0xxx).
3 Screw down the wires using the screws on the top of the connector. Figure 6.23 Connecting power cable to TVS module GPS connectors On the base station, the GPS connectors are black. The base station supports two GPS connectors: one connector is used to supply the GPS signal, either by a direct connection to the GPS device, or by a daisy chain connection to another base station in the cell.
An RS-422 line also feeds 422Data+ and 422Data-, to allow data communication from the GPS device to the base station. This is one-way communication, with the GPS device giving the base station time information. The 18V+ and ground pin supply power to the GPS device from the base station. The GPS device uses 18 volts DC at 150 milliamperes. Note: If you move the GPS receiver after supplying power to the GPS, you must reconfigure the receiver using the Trimble synchronization kit.
For base station configuration, the serial interface connector lets you directly connect the base station to a computer. The seven-pin connector is an RS-232 cable (10 ft.), physical interface. Figure 6.25 Serial interface connector A Ground B Not used C Not used D Not used E Tx data F Rx data G Not used Serial interface connecting cable Cable 597-6028-0010 has a female, circular connector on one end, and a DB-9 female connector on the other end. Plug the DB-9 end of the cable into a computer.
• The base station contains an antenna connector with a 1/4 wave lightning protector. You do not need to place an external lightning protector in the coaxial cable. Connecting the antenna to the base station To attach the antenna to the base station: 1 Mount the antenna according to the manufacturer’s instructions. 2 Connect one end of a short coaxial jumper to the antenna. Connect the other jumper end to the main coaxial cable.
Use the GPS-to-base station cable to attach the GPS unit to one of the base stations in the cell. To connect the cable to the GPS unit and to the base station (both of which have already been installed and mounted): 1 Connect the cable’s molded, circular female connector to the GPS unit. 2 After connecting the cable to the GPS unit, run the cable to the base station. Plug the cable’s other end into the base station’s GPS connector. 3 Secure the cable that you just ran to an appropriate support structure.
Powering tips • It is recommended that you use a redundant power supply for base stations. • Each base station requires 48 volts DC at 3.0 amps maximum. • The ground of the power can be either negative or positive. The 48 volt power input to the base station is floating, so either the positive or negative can be grounded. • Power input is polarity sensitive, so be sure you connect V+ and V- properly.
C 7 H A P T E R INSTALLING THE RACKMOUNT BASE STATION (RMB) Chapter overview This chapter describes how to install the rackmount base station (RMB). It describes: • Installing the cabinet onto a 19 inch rack • Installing the power supply and switch • Installing the RMB into the base station cabinet • Connecting the RMBs to the cell and to cell-site components Before you begin Before you install RMBs: • It is recommended that you assign a name to the RMB.
Installation overview This section provides an overview of the tasks you will perform when installing RMBs. To install the RMBs: 1 Install the mounting brackets to the cabinet, then attach the cabinet to the 19" rack. Note: Do not operate the system before you have securely mounted the cabinet to a standard 19" rack that can handle the weight of the total system.
Installing the mounting bracket and attaching cabinet to the 19-inch rack Before inserting RMBs into the cabinet, attach the cabinet to the rack. To attach the cabinet to the rack: 1 Attach a mounting bracket to the left side and right side of the cabinet using the 16 supplied screws (8 per side). Figure 7.1 Cabinet mounting bracket Step 1: Attach to cabinet. Step 2: Attach to rack. 2 Attach the cabinet to the rack with the 8 supplied screws, 4 for each side.
Attaching the switch and power supply to the rack Figure 7.2 shows where the switch and power supply should be installed on the rack, in relation to the cabinet and RMBs. Figure 7.2 Location of switch and power supply in rack RMBs Switch Power supply Installing the RMBs into the cabinet To install the RMB in the cabinet: 1 Grasp the RMB by handles on each side of the RMB. 2 Slide the RMB into the cabinet, aligning the guides along the side of the RMB with the gliders inside the cabinet.
Connecting RMBs to cell (cell wiring) There are minimal wiring tasks for you to perform, as the RMB simply slides into the preexisting wiring when you place the RMB in the cabinet. The cabinet into which the RMB is installed has a pre-wired harness. This harness supplies power and Ethernet connectivity to the RMB. After you connect the antenna to the appropriate connector, the RMB also receives airlink traffic. Finally, the harness supplies an alarm capability to the RMB, as well as a GPS signal.
Figure 7.3 shows how a cell, 4 RMBs, and ancillary equipment are wired together. Figure 7.
Connecting power to the RMBs This section describes how to supply power to RMBs in the cabinet, as well as recommendations for the type of power supply to use. When choosing a power supply, keep in mind: • Each base station requires 150 watts at 48 volts. So, if your cabinet holds 8 RMBs, the power supply should provide 1250 watts, at a minimum. • The power supply you choose should use an “n + 1” configuration, so that the RMBs have a backup power source in case one of the power supply modules fails.
Figure 7.4 shows the location of the power connection on the bottom of the cabinet. Figure 7.4 Power connections on bottom of cabinet DO NOT DISCONNECT.
• Size the UPS according to the efficiency of the DC power supplies and power requirements of the other ancillary equipment, such as the Ethernet switch and backbone network equipment. • Consider the time you want to allow the system to operate on the UPS battery power. Grounding the RMBs There is one grounding bar in each cabinet. Each bank of 4 RMBs are grounded to the bar. The grounding bar also contains locations for grounding terminals so that you can ground the RMBs to your building’s ground bar.
Turning on the RMB’s power The front panel of the RMB has a programming (diagnostics) cable connection, 5 lightemitting diodes, and a power button. Figure 7.6 shows the front panel of the RMB. Figure 7.6 RMB LEDs DIAGNOSTICS PWR NET PPS AIR ALM POWER To turn on the RMB, press the power button. The LEDs then light. Table 7.1 describes what the base station LEDs indicate. Table 7.
GPS connectors Figure 7.7 shows the GPS connectors that the base station supports. Figure 7.7 GPS connector An RS-422 line feeds 1PPS+ and 1PPS- with the time synchronization pulse from the GPS equipment to the base station. An RS-422 line also feeds 422Data+ and 422Data-, to allow data communication from the GPS device to the base station. This is one-way communication, with the GPS device giving the base station time information.

C 8 H A P T E R TESTING AND MANAGING THE NETWORK Chapter overview This chapter describes how to test the network before the network is used by ISPs. The chapter also provides an overview of network management tasks. Testing the setup overview This section provides an overview of the steps that help network access providers test the setup of the network before the network is rolled out. To test the network setup: 1 Install and configure the AP server, as described in this guide.
Testing the connection between the AP server and the provisioning server To make sure that the AP server and the provisioning server are communicating: 1 On the provisioning server, open the home page of the provisioning server interface. For more information about the provisioning server, refer to Chapter 2, “Working with the provisioning server” in the guide “Configuring and monitoring the ISP network.” 2 On the home page, check the Access Provider Connection group.
Using SNMP server to receive and report trap information The network access provider can use an SNMP management station. This station reports all abnormal system conditions. Based on the severity of the event, the SNMP management system issues visual, audio, email and paging alerts. Using Syslog to receive system information The base stations and CPEs use Syslog to record system information to a remote Syslog server for processing.
Alternatively, network access providers can use any SNMP interface (such as OpenView/ Netview) to perform system configuration and management tasks. For CPEs, ISPs can use the provisioning server interface to show information about CPEs such as their serial number, the host computers they serve, the IP addresses assigned to the host computers, and the base station that serves the CPE. Configuration management overview This section describes features that help you configure devices on your network.
