A. Third-generation (3G) is the term for the latest generation of mobile services, which provide advanced voice communications and high-speed data connectivity, including access to the Internet, mobile data applications, and multimedia content. The ITU, working with industry-standards groups from around the world, has defined the technical requirements and standards as well as the spectrum for 3G systems under the International Mobile Telecommunications-2000 (IMT-2000) program. The ITU requires that IMT-2000 (3G) networks deliver (among other capabilities) improved system capacity and spectrum efficiency over 2G systems and that they support data services at minimum transmission rates of 144 kbps in mobile (outdoor) and 2 Mbps in fixed (indoor) environments.
Q. What is the difference between EVDO and HSPA?
A. EVDO and HSPA are parallel 3G data standards in the Code Division Multiple Access (CDMA) and Global System for Mobile Communications (GSM) environments. EVDO evolved from the Code Division Multiple Access 2000 (CDMA2000) standards, whereas high-speed packet access (HSPA) evolved from the Universal Mobile Telecommunication System (UMTS) standard that was developed for the countries using GSM technology.
Q. In general, what is the level of adherence to the 3G Partnership Project 2 (3GPP2)? For example, does the Cisco® 3G PCI Express Minicard Standard Form Factor F2 support EVDO Rev A quality of service (QoS)?
A. Adherence to the EIA/TIA and CDMA Development Group (CDG) standards depends on the carrier implementation and a combination of modem hardware and firmware and software. All Cisco 3G PCI Express Minicard Standard Form Factor F2 modems comply with the standards, but the specifics of carrier implementations vary by carrier.
Q. Who are the carriers' examples for CDMA and GSM 3G standards?
A. 1xRTT, EVDO Rev0, and RevA CDMA technologies used in the United States do not require SIM cards. The examples of such carriers are Verizon and Sprint. GSM-based technologies require SIM cards to be installed in the device; such carriers include AT&T, T-Mobile, Vodafone, etc. Please refer to the Cisco 819 Data Sheet for more information.
Q. Does the Cisco 3G PCI Express Minicard Standard Form Factor F2 support Mobile IP or Simple IP only?
A. The CDMA 3G PCI Express Minicards Standard Form Factor F2 support Mobile IP (MIP) on the modem. Depending on the configuration on the carrier network, it could be set to either MIP only or MIP preferred mode. In the MIP preferred mode, when MIP fails, the modem falls back to Simple IP. The GSM 3G wireless WAN (WWAN) does not have a Mobile IP stack.
Q. How does the modem select the service to which to attach? Does it switch to a better service when one is available?
A. Yes. For GSM networks, the modem always looks for HSPA/HSPA+ as the first choice. If HSPA/HSPA+ is not available, the modem downshifts to the next best available radio network; that is, UMTS to EDGE and finally to General Packet Radio Service (GPRS). If you have only EDGE service, the modem continues to scan in the background for UMTS or HSPA service. If the UMTS or HSPA service becomes available, the modem automatically switches to that service. For CDMA networks, the modem always looks for EVDO Rev A first, then Rev 0, and then 1xRTT.
Q. What factors affect throughput on the 3G WWAN?
A. Several factors can affect throughput and performance:
• Congestion: 3G WWAN data services use a shared wireless medium; therefore, the number of active users in a cell site affects throughput.
• Coverage: The distance from the cell tower affects throughput. The further you are located from the cell tower, the lower the achievable throughput. A site survey is recommended as part of the installation process to help ensure adequate network coverage.
• Interference: RF noise from nearby devices can inhibit performance.
Q. Are the Cisco 3G WWAN interfaces suitable for use as primary links?
A. The 3G wireless standards for data rate and latency performance have continuously improved. Today both Evolution-Data Optimized or Evolution-Data only EVDO and HSPA services offer fractional T1 data rates and latency below 100 milliseconds (ms). For sites and applications that have low and intermittent data usage (such as bank ATMs, kiosks, and gas stations), the Cisco 3G WWAN interface may be suitable.
Q. Can I run voice-over-IP (VoIP) traffic over Cisco 3G WWAN Express Cards?
A. Yes. It is recommended to use the latest 3G technology-EVDO Rev A and HSPA+/HSPA-to run VoIP over a 3G link.
Q. Is latency a problem with the Cisco 3G solution?
A. Latencies vary by technology. Depending on the service available in your area and the applications you are running over your link, latency may be a concern. The most advanced technologies support latencies of less than 100 ms.

A. Yes, you can use the 12V Nominal power supply with 24V, but only if the operating range of the 24V source is within the 10V to 36V limits. The 12V adapter is intended to work with automotive applications that can have a wide range of voltage under fault conditions. If your 24V source is regulated or even semi regulated, it should have no problem powering the 12V Nominal adapter. One caution: the 12 VDC adapter does not have electrical isolation from input to output; the input negative is connected to output negative, so the input negative will be connected to the 819 router chassis ground.
Q. What is the IP41 rating?
A. The protection of enclosures against ingress of dirt or against the ingress of water is defined in IEC529. The degrees of protection are most commonly expressed as "IP" followed by two numbers; for example, IP41, where the numbers define the degree of protection. The first digit, foreign bodies protection, shows the extent to which the equipment is protected against particles, and the second digit, water protection, indicates the extent of protection against water. Number 4 in the first digit represents the protection against the foreign body that has a diameter longer than 1 mm, and number 1 in the second digit represents the protection against water dripping or falling vertically.
Q. Is the AC power adapter IP41 rated?
A. The Cisco 819 ISR AC power adapter is not IP41 rated. Installation must include protection from the power adapter and power plug from water.
Q. What is DC power adapter IP rating?
A. The DC power adapter for the Cisco 819HG and 819G is not IP41 rated. It is IP41 rated for Cisco 819HGW ISRs. Martek railway DC power adapter is IP65 rated.
Q. What are the DC power adapter mounting options?
A. The DC power supply may be mounted to a wall using four #6 pan or round-head wood screws for the mounting holes on the supply.

• Fleet management
• Micro branch office
• Public safety
• Smart connected community or city
• Professional services
Q. How are the Cisco 3G routers integrated with Cisco IOS Software?
A. An Interface Cellular based on an asynchronous serial interface has been created in Cisco IOS Software to support these cards. This interface is a dial-on-demand routing (DDR) interface, so a data call is initiated when there is traffic to be routed over the 3G networks. Refer to the software configuration guide for more information about how to use the Cisco 3G.
Q. What management capabilities are available for the Cisco 3G PCI Express Minicard Standard Form Factor F2 card for the Cisco 819 ISRs?
A. You can configure and monitor the Cisco 3G Express Card from the router CLI using Cisco IOS Software commands that allow you to:
• Activate the 3G modem (only for CDMA)
• Configure the data profile (only for HSPA)
• Upgrade 3G modem firmware either locally or remotely
• Dial in and bring up the 3G link remotely through Short Message Service (SMS) and voice
• Monitor the signal strength, available network and service, and data-connection statistic
• Use SIM locking/unlocking; it adds SIM security by verifying the SIM PIN at modem power-up
• Use mobile equipment personalization (MEP) unlocking, which allows locking the modem or high-speed WAN interface card (HWIC) to a particular cellular carrier, thus allowing the carrier to subsidize the equipment. This feature allows end users to use the modem with other carriers after the locking period is over, as required in some geographical regions and countries
• Use Open Mobile Alliance Diagnostic & Monitoring (OMA-DM) activation, which allows CDMA modems to be activated and provisioned using the OMA-DM protocol
For remote-management capabilities, the Cisco 3G PCI Express Minicard Standard Form Factor F2 card supports the Simple Network Management Protocol (SNMP) interface 3G MIB, allowing access to the standard interface counters. The interface MIB also provides traps for interface up, interface down, and modem presence events. (Note that a cellular MIB that allows polling of signal and network statistics is under development.)
It supports collecting modem logs through remote Diagnostic & Monitoring capability.
The Cisco 819 supports configuration through a Cisco web-based application, Cisco Configuration Professional.
Q. What new 3G MIB features are supported on the Cisco 819 ISRs?
A. In addition to traditional 3G WWAN, ENTITY, and IF MIB support, the Cisco 819 ISRs support 3G WWAN MIB persistence, which allows SET objects to survive from router reloads and modem power cycle. New MIB objects will be implemented for SMS statistics and Global Positioning System (GPS) data: ftp://ftp.cisco.com/pub/mibs/v2/CISCO-WAN-3G-MIB.my.
Q. What protocol is used by MC8705 modem?
A. The Sierra Wireless MC8705 modem uses direct IP protocol to transmit packets between Cisco IOS Software and the modem. The cellular interface created for the HSPA+ modem is hardcoded with "slip" encapsulation to differentiate from the existing GSM/HSPA modems, which have a Point-to-Point Protocol (PPP) link to Cisco IOS Software. The migration to direct IP is mainly directed by the increase in data throughputs. The 4G/LTE modems are also direct IP-based protocol. Please refer to the Configuring Cisco EHWIC and 880G for 3.7G/3.5 configuration guide for more information about how to configure MC8705-based Cisco 819 ISRs.
Q. How can I debug direct IP sessions in the Cisco 819HG+7 and 819HGW+7 ISRs?
A. Execute the debug cellular 0 message callcontrol command to debug direct IP call setup and termination.
Q. Does the Cisco 819 support SIM online insertion and removal (OIR)?
A. The Dual SIM feature implements auto-switch and failover between two cellular networks. The switch is controlled by a failover timer. The failover timer starts when the modem powers up or changes service status from normal to others. When the failover timer expires, the modem switches from the primary slot (default is slot 0) to the secondary (failover) slot (default is 1). When switchover happens, the modem is power cycled to activate the new SIM. The default failover time is 2 minutes. The maximum number of retries is 10. Please refer to the configuration guide for more details: http://www.cisco.com/en/US/docs/routers/access/1800/1861/software/feature/guide/mrwls_hspa.html.
A. Voice-initiated data callback (also called dial-in), which is implemented in previous Cisco 3G products, requires customers to subscribe to a voice plan. However, not all service providers offer voice service for data-only modems. SMS initiated data callback addresses this limitation. It allows customers to set up a data connection by sending a text message to the modem. This feature includes message screening using the originating number. This feature improves the feature security and eliminates unauthorized callback requests.
A. The Cisco IOS EXEC command show cellular <slot> gps displays GPS state, mode, latitude, and longitude information.
Q. Do the 3G Cisco 819 ISRs support the National Marine Electronics Association (NMEA)?
A. NMEA is a combined electrical and data specification for communication between marine electronic devices such as echo sounders, sonar devices, anemometers, gyrocompasses, autopilots, GPS receivers, and many other types of instruments. It has been defined by-and is controlled by-the U.S.-based National Marine Electronics Association. For the Cisco 819, a virtual serial port will be implemented to export NMEA-formatted GPS data. Through COM port emulation software on a PC, location-based applications running on the PC can retrieve real-time GPS data from the modem.
Q. Do the 3G Cisco 819 ISRs support the NMEA streaming over the onboard serial interface?
A. The NMEA streaming feature delivers GPS data from the modem through a virtual COM port. This delivery requires the device running the GPS-based application to set up a reverse Telnet session to the cellular NMEA TTY line using TCP/IP. For devices that are not capable of establishing a Telnet session, such as ticket machines, the Cisco 819 ISR can deliver NMEA data through an onboard serial interface. The feature provides a Cisco IOS Software interface that allows you to configure NMEA 0183 standard (4800 bps, 8-1-N), NMEA 0183HS (38400 bps, 8-1-N), and any standard RS-232 configuration for future needs.
Q. Do the embedded 3G modems on the fixed Cisco 819 ISRs support the diagnostic monitor port on the chassis?
A. Yes. Cisco 819 ISRs support 1 mini Type B USB port for 3G modem diagnostics and provisioning. Users can also collect logs remotely with remote Diagnostic & Monitoring capabilities. Only 3G SKUs have this mini Type B USB port; Wi-Fi-only, non-Wi-Fi, and non-3G SKUs do not have this port.
Q. How do I upgrade the CDMA modem Preferred Roaming List (PRL)?
Q. What other advanced Wi-Fi radio technologies are supported by AP802?
A. AP802 delivers industry-leading performance for secure and reliable wireless connections. Enterprise-class silicon and optimized radios deliver a robust mobility experience using Cisco M-Drive technology, which includes:
• ClientLink improves reliability and coverage for older clients.
• BandSelect improves 5-GHz client connections in mixed client environments.
• VideoStream uses multicast to improve rich-media applications.
Q. Is Dynamic Frequency Selection (DFS) supported on AP802?
A. DFS is currently not supported for FCC SKUs pending FCC certification.
Q. How many radios are available on AP802?
A. AP802 has 802.11a/b/g/n dual radios: 2.4Ghz and 5.0Ghz.
Q. Can the AP802 802.11 radio and Cisco 819 cellular radio operate at the same time?
A. Yes. Both AP802 Wi-Fi radios and the Cisco 819 cellular radio can operate at the same time. The AP802 2.4-GHz radio can serve as an access point, and the 5.0-GHz radio can act as a client in work-group bridge (WGB) mode to provide the backhaul function to the existing Wi-Fi network.
Q. What is the router behavior when the reset button is pressed in Cisco 819 ISRs?
A. When the reset button is pressed while the device is powering up, the router will go through configuration and image recovery processes: a) Rommon will set the console baud rate to 9600 and RM1 (read only) Rommon will be executed; that is, if RM2 (upgrade) Rommon is programmed; b) No backup of the original startup config will be performed; c) If there is a Cisco IOS Software image with *.default name, that image will be loaded by Rommon; d) If no *.cfg config file is available on flash or NVRAM, the original startup config will be erased and the router will boot up with empty configuration.
Q. What is the AP802 behavior when the reset button is pressed in Cisco 819 ISRs?
A. When the reset button is pressed while the device is powering up, the access point will go through configuration and image recovery processes: a) if a cpconfig-ap802.cfg config file exists in flash memory, then config.txt will be overwritten with contents of the cpconfig-ap802.cfg file; b) if the cpconfig-ap802.cfg config file does not exist in flash memory, the config.txt file will be deleted. The access point will boot up with empty configuration in this case; this phase is the configuration recovery phase; c) the access point on the second core will boot with the first image on the flash memory. This phase is the image recovery phase.
Q. What is the environmental high temperature logging feature?
A. Cisco 819 ISRs support six temperature sensors in the system: System Ambient, Sensor 1, Sensor 2, Sensor 3, and Sensor 4 (all temperatures read from MCU), and 3G (temperature read from the 3G modem). When the temperature threshold is crossed, action is taken based on the information in Table 9. Crossed means that the measured temperature is "less than" the low threshold; or that the measured temperature is "more than" the high threshold. Temperature is sensed or read every 30 seconds, and action taken is based on information in Table 9.
Table 9. Temperature Thresholds and Associated Actions
Q. Can I use IP Security (IPsec) with the Cisco 3G PCI Express Minicard Standard Form Factor F2 card?
A. Yes. All Cisco ISR security features are supported on the Cisco 3G PCI Express Minicard Standard Form Factor F2 interface. IPsec has been tested in both site-to-site and Dynamic Multipoint VPN (DMVPN) configurations with the new Cisco 3G WWAN Express Cards.
Q. How many VLANs are supported in Cisco 819 ISRs?
A. The Cisco ISR 819 supports 8 VLANs by default, but will support 16 VLANs in Q1CY13.
Service Plans and Carriers
Q. How do I get a service plan for the Cisco 819 ISRs?
For the GSM express card, the service plan information is included in the SIM card. You must purchase the SIM card from your local wireless carrier. In general, service plans should be metered plans. Several of the unlimited data plans are designed for laptop computers and PDAs and not for routers, where a customer can have multiple data devices.
For the CDMA express card, the carrier must activate the modem. Typically this activation involves providing account information as well as the ESN of the modem.
Q. How do I activate my Cisco 3G?
A. The service activation procedure varies by wireless carrier. Activation can be performed through a phone call or by logging into a specific website so that the carrier can perform the activation. To activate a modem, typically you need to have a reseller agreement with the carrier. The typical scenarios follow:
• Managed services or wireless carrier: If you purchased the modem through a wireless carrier or affiliate, that carrier or affiliate should activate the modem.
• Reseller: If your reseller has an agreement with a wireless carrier, the reseller may perform service activation. If the reseller does not have a relationship with a wireless carrier, the reseller may partner with a wireless agent to activate the modem.
Q. Is over-the-air (OTA) provisioning supported, or is provisioning performed by a technician during installation over the connection to the console port?
A. OTA provisioning is supported; however, the OTA protocols of different wireless network operators vary. Sprint supports OMA-DM provisioning and Verizon supports OTASP provisioning.
