The following inform ation is for FCC compliance of Class A devices: 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 instruction 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.

The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequency energy. If it is not
installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to
comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable
protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.

Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital
devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television
communications at your own expense.

You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its
peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:

• Turn the television or radio antenna until the interference stops.

• Move the equipment to one side or the other of the television or radio.

• Move the equipment farther away from the television or radio.

• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits
controlled by different circuit breakers or fuses.)

3.4 BWX 8305 Basestation Components

A Cisco BWX Mobile WiMAX system provides wireless broadband access to a core network, typically
to the Internet or to any local or wide area network (LAN/WAN). When a Service Provider has
established BSs in a given coverage area, the subscriber connects a BWX 110 or BWX 210 Desktop
Modem to their computer (or inserts a BWX 120 PCMCIA Modem into their laptop) to access the
network without the need for a professional installer.

This is what Cisco refers to when it says its system is “zero-install®”: no truck rolls, no professional
installation schedule for the consumer. In fact, some Service Providers have their subscribers pick up
their Modems at retail stores, or, in some cases, simply mail the Modems to the subscribers. The
subscriber Modem is generally referred to as Subscriber Station(SS). The SSs can be Desktop Modems
that attach via an Ethernet cable to the user’s PC, or they can be Wireless PC Cards that insert in the
PCMCIA slot on a laptop computer.

In Release 7.0 Cisco offers three Subscriber Stations: the BWX 110 Desktop Modem, the BWX 210
Desktop Modem, and the BWX120 PCMCIA Modem Card. The BWX 110 Desktop Modem covers a 2
MHz frequency range and comes with a Liquid-crystal Display (LCD) front panel, that shows signal
status, while the BWX 210 Desktop Modem covers a 5 MHz frequency range, has no LCD display and
is simply switched on/off. The BWX 120 PCMCIA plugs into laptops for true portability to change
locations easily, where coverage is available.

The entire BWX Mobile WiMAX system (Figure 3-1) has four main components: one or more
Basestations, Subscriber Stations (SSs, also referred to as Modems), the Element Management System
(EMS), and the Broadband Wireless Gateway (BWG). The BS portion of the system consists of the BWX
8305 Basestation, BWX 8303 Basestation Timing System, and the BWX Basestation Antenna.

Chapter 3 Overview

The BS performs the conversion of RF signals to digital signals for packets transmitted uplink (SS to
BS), and converts digital signals to RF signals transmitted downlink (BS to SS). The BS interfaces with
the BWG and either directs traffic to/from the BWG (residential service) or tags the traffic to route
to/from a private network (Business/Enterprise service). The BWX Antenna is the antenna that is
mounted on a tower, rooftop, or other structure. The BS is available as a BWX 8305 Basestation or as a
BWX 2305 Basestation. The BWX 8305 has an BWX Antenna with 8 antenna elements, while the BWX
2305 has 2 individual dipole antennas.

Note The BWX 8303 Basestation Timing System is required for WiMAX Basestations.

The BS uses a Global Positioning System (GPS) antenna, connected to a BWX 8303 Basestation Timing
unit. The BWX 8303 Basestation Timing System (formerly known as External GPS Unit, EGU) is
mandatory for BSs in all WiMAX deployments starting with Release 7.0 and subsequent releases.

For network deployments, the BS with BWX 8303 Basestation Timing System is the only supported
configuration in WiMAX deployments for Release 7.0 and subsequent upgrades. Warranty and ongoing
TAC support on the BS only covers BSs deployed with the supported configuration. Existing customers

having BSs deployed with built-in GPS must order and install the BWX 8303 Basestation Timing
System as a prerequisite prior to performing software upgrade to Release 7.0 and subsequent
releases. One BWX 8303 Basestation Timing System supports up to three BSs at a cell site. Installation

of the BWX 8303 Basestation Timing System must be performed by qualified personnel to preserve
warranty for the BS at the same site.

For WiMAX deployments, an accurate timing system as the source of synchronization is a requirement for
the BS to function properly. The BWX 8303 Basestation Timing System provides this timing source to the
BS.

The maximum throughput varies by Model type and RF channel conditions.

Chapter 3 Overview

The EMS is a set of software applications that the Service Provider uses to configure, communicate with,
and manage all the system elements directly related to the Broadband Wireless Access system. EMS
provides a single point for managing BWG-toBS, BWG-to-EMS, BS, and SS communications in a
WiMAX network.

The EMS is an IP-based element manager designed in a Server-Client relationship and runs on either
Windows or Solaris Operating Systems. Most Service Providers use the Client EMS Configuration &
Alarm Manager (CAM) application to interface with the system. All of the functions that can be
performed through the CAM can also be performed through a Command Line Interface (CLI), which is
a common computing language across platforms.

3.5 Beamforming

Cisco BWX 8305 Basestation antennas contain 8 elements (Figure 3-2), with a gain of 16 dB in the panel
configuration. Their combined effect is to concentrate the downlink data into a beam with maximum gain
at the location of each target SS (

Similarly, in the uplink the data transmitted by each SS is received by the 8 antenna elements with
different phases due to the differences in propagation distance from an SS to each antenna element. The
contributions from an SS are added up coherently after adjusting their phases for maximum gain. This
effect, which we call beamforming, is equivalent to having up to 18 dB of additional gain in the downlink
and up to 9 dB additional gain in the uplink. It allows the Cisco BWX Mobile WiMAX system to ate at
a much lower power level than would otherwise be necessary for the same results.
