Multimode Modem

The 4G GRWIC comes with a Sierra Wireless multi-mode modem that provides the RF interface for the modem. The modem complies with PCI Express Mini Card Electromechanical Specification, revision 1.2. The hardware includes the following:

■Multiple LED indicates modem status, service, and signal strength

■A single Subscriber Identity Module (SIM)

The modem supports one of the following standards:

■ 3G Evolution-Data Optimized (EVDO or DOrA) Mode —EVDO is a 3G telecommunications standard for the wireless transmission of data through radio signals, typically for broadband Internet access. EVDO uses multiplexing techniques including code division multiple access (CDMA) as well as time division multiple access (TDMA) to maximize both individual users' throughput and the overall system throughput.

–Code Division Multiple Access (CDMA) is a method of dividing a radio spectrum to be shared by multiple users through the assignment of unique codes. CDMA implements spread spectrum transmission.

–Time Division Multiplex Access (TDMA) is a type of multiplexing where two or more channels of information are transmitted over the same link by allocating a different time interval ("slot" or "slice") for the transmission of each channel; that is, the channels take turns to use the link. Some kind of periodic synchronizing signal or distinguishing identifier usually is required so that the receiver can tell which channel is which.

■ 4G-LTE — Designated as a fourth-generation (4G) mobile specification, LTE is designed to provide multi-megabit bandwidth, more efficient use of the radio network, latency reduction, and improved mobility. This combination aims to enhance the subscriber's interaction with the network and further drive the demand for mobile multimedia services.

Sierra Wireless AirPrime MC7700, MC7750, and MC7710 modules each deliver up to 100 Mbps download speeds and 50 Mbps upload speeds (within 20 MHz bandwidth), integrated GPS capabilities, and support for both Linux and Windows.

Envrionmental Specifications

Environmental Specifications lists the environmental specifics of the 4G GRWIC.

Power Specifications

4G GRWIC draws +10.8V, +5V and +3.3V from the host platform. The +10.8 V is used exclusively for the modem +3.3 V power requirement. The +3.3V is for the board I/O. The power sourcing of +10.8 V rail (5000 mW) from the host precludes the need for any onboard modem power storage. The +5 V from the host is used to create a +3.3 V I/O voltage for the CPU, FPGA, FLASH, analog Muxes and LEDs, as well as the +1.0 V CPU Core voltage.

Subscriber-Identity-Module (SIM) power is provided directly by the modem.

Preventing Electrostatic Discharge Damage

Electrostatic Discharge (ESD) damage can occur when electronic cards or components are handled improperly, and can result in complete or intermittent failures.

To prevent ESD damage, follow these guidelines:

■Always use an ESD wrist or ankle strap and ensure that it makes good skin contact.

■Connect the equipment end of the strap to an unfinished chassis surface.

■Place a removed compact SIM card on an antistatic surface or in a static shielding bag. If the card will be returned to the factory, immediately place it in a static shielding bag.

■Avoid contact between the card and clothing. The wrist strap protects the card from ESD voltages on the body only; ESD voltages on clothing can still cause damage.

■Do not remove the wrist strap until the installation is complete.

• Only trained and qualified personnel should install, replace, or service this equipment. Statement 1030

Before You Begin Installation

Before installing the module, verify that the following guidelines have been met:

■Clearance to the I/O-side view is such that the LEDs can be easily read.

■Cabling is away from sources of electrical noise, such as radios, power lines, and fluorescent lighting fixtures. Make sure that the cabling is away from other devices that might damage the cables.

■Airflow around the switch module and through the vents is unrestricted.

■Temperature around the unit does not exceed 140°F (60°C). If the switch module is installed in a closed or multirack assembly, the temperature around it might be higher than normal room temperature.

■Relative humidity around the switch module does not exceed 95 percent (noncondensing).

■Altitude at the installation site is not higher than 10,000 feet.

■For 10/100 and 10/100/1000 fixed ports, cable lengths from the switch module to connected devices are not longer than 328 feet (100 meters).

Overview of 4G-LTE Networks

4G-LTE mobile specification provides multi-megabit bandwidth, more efficient use of the radio network, latency reduction, and improved mobility. LTE solutions target new cellular networks. These networks are designed to support up to 300 Mbps peak rates in the downlink and up to 75 Mbps peak rates in the uplink. The throughput of these networks is higher than the existing 3G networks.

4G-LTE Packet Core Network Architecture shows a 4G-LTE packet core network and the network elements it contains.

Prerequisites

To configure the 4G GRWIC, you must meet the following requirements:

■Have 4G-LTE network coverage where your router will be physically located. For a complete list of supported carriers, see the product data sheet.

■Subscribe to a service plan with a wireless service provider and obtain a SIM card.

■Install the SIM card before configuring the 4G-LTE Wireless WAN GRWIC. For instructions on how to install the SIM card, see Installing the SIM Card.

Configuration Restrictions

Be aware of the following restrictions that exist with a cellular network:

■Currently, cellular networks support only outgoing calls.

■Throughput—due to the shared nature of wireless communications, the experienced throughput varies depending on the number of active users or congestion in a given network.

■Cellular networks have higher latency compared to wired networks. Latency rates depend on the technology and carrier. Latency may be higher because of network congestion.

■Any restrictions that are a part of the terms of service from your carrier.

Data Account Provisioning

For 4G-LTE GRWICs, the numbering for Slot 0, wic 0 and port 0 is 0/0/0 for all commands.

To provision your modem, you must have an active wireless account with a service provider and a SIM card installed.

To provision your data account, see the following topics:

■Verifying Signal Strength and Service Availability

■Configuring a Modem Data Profile

Verifying Signal Strength and Service Availability

SNMP Requirements

The following are SNMP-related requirements for the 4G GRWIC:

■If your router runs the SNMP agent, you must configure appropriate access control (e.g. SNMP-server community) using the Cisco IOS CLI for the NMS (Network Management System) and agent to work properly.

■Cisco strongly recommends that you configure SNMP V3 with authentication/privacy when implementing SNMP SET operation.

SNMP MIB Overview

Simple Management Network Protocol (SNMP) development and its use is centered around the Management Information Base (MIB). An SNMP MIB is an abstract database, a conceptual specification for information that a management application may read and modify in a certain form. This does not imply that the information is kept in the managed system in that same form. The SNMP agent translates between the internal data structures and formats of the managed system and the external data structures and formats defined for the MIB.

The SNMP MIB is a tree structure with conceptual tables. (Cisco 4G MIB is discussed in detail in the next section.) Relative to this tree structure, the term MIB is used in two senses. In one sense, it is actually a MIB branch, usually containing information for a single aspect of technology, such as a transmission medium or a routing protocol. A MIB used in this sense is more accurately called a MIB module, and is usually defined in a single document. In the other sense, a MIB is a collection of such branches. Such a collection might comprise, for example, all the MIB modules implemented by a given agent, or the entire collection of MIB modules defined for SNMP.

A MIB is a tree where the leaves are individual items of data called objects. An object may be, for example, a counter or a protocol status. MIB objects are also sometimes called variables.

MIBs can be classified into three categories:

■ IF MIBs —Describes interface statistics

■ Cisco-Entity-Vendortype-OID-MIB.my —ENTITY-MIBs are used to provide general hardware type for both the HWIC and the modem. CISCO-ENTITY-VENDORTYPE-OID-MIB assigns OIDs for Cisco components (including the HWICs & the modems). The OIDs are then used as the values of entPhysicalVendorType in the ENTITY-MIB.

■ 3G/Wireless MIBs —Cellular or wireless-specific MIBs

Verifying Service Availability

The following is sample show cellular all command output for a scenario where the antenna is disconnected and a modem data profile has not been created. The errors in this case have been indicated with the symbols “ <-- ”:

Successful Call Setup

The following sample output was taken when a call was set up using a chat script. It shows a received IP address from the network. Call setup is successful, and data path is open.

Modem Troubleshooting

The RSVD port on the faceplate of the 4G GRWIC provides access to the debug port on the modem. Use an industry-standard diagnostic tool like Qualcomm QXDM to perform remote radio-level diagnostics and traffic monitoring on the modem.

Use the following test command to turn diagnostics on:

router# test cell-hwic slot/port/wic dm-port on

To enable test commands, you must enter the service internal command in the global configuration mode.

Modem Settings

For HWIC-3G- deployments in North America and for carriers operating in the 850MHz and 1900 MHz bands, you can prevent long network attach times by making the following changes to the modem settings.

The output of show cellular x/x/x all command shows the following:

■No network attach

■RSSI value is -110 dB

■Band selection is set to AUTO

For information on troubleshooting the modem, see Modem Troubleshooting.

Retrieving the Electronic Serial Number (ESN)

If your network provider requests the 11-digit decimal equivalent of your ESN, you must retrieve your ESN, the convert it to decimal notation. See also, Converting Hexadecimal ESN to Decimal Notation.

The ESN number is located directly on the modem label in hexadecimal notation. It can also be retrieved using the Cisco IOS CLI using the show cellular all command.

The sample output below shows the ESN number:
