Activation and Provisioning FAQs

1. Does the GX400 or GX440 need a SIM card? If so, how do I get one?
a. The GX400 for EVDO networks does NOT require a SIM card and activation can be done with the appropriate network operator representative and the ESN of the device located on the bottom.
b. The GX400 for HSPA+ DOES require a SIM card, which can be procured from the appropriate network operator representative.
i. SIM cards used for other AirLink HSPA devices CAN be used in the GX400.
c. The GX440 DOES require a SIM card. This is notable, since this is the first time that an AirLink device on the VZW network requires a SIM card. SIMs can be procured from your VZW representative during the course of account activation.

2. For what networks is the GX400 available or certified on?
a. The GX400 is currently certified for Verizon, Sprint and AT&T
b. The GX400 is available for use on mobile networks in Europe, The Middle East, Africa and Asia where specific network operator approval is not necessary.
c. The GX400 is available for use on the Telstra network in Australia.
d. Certification for Canadian networks is planned for 2012.

3. For what LTE networks is the GX440 available or certified on?
a. Currently the only LTE network that supports the GX440 is the Verizon Wireless Network in the US. AT&T LTE approval and availability is planned for the 2nd half of 2012.

4. Can I use my AT&T (or other Worldwide network operator) LTE SIM to obtain AT&T (or other) LTE service on a GX440 Verizon Wireless LTE device?
a. No, GX440 Verizon Wireless LTE device is intended to be used with Verizon Wireless LTE SIMs only. The GX440 Verizon Wireless LTE device will not operate with an AT&T LTE SIM.

5. Where is the SIM slot on the GX400 and GX440?
a. The SIM slot is located on the front left (as you are looking at the side with the lights and the reset button) behind the plastic cover.
b. To access the SIM slot on the device you must remove the plastic cover with a 2mm or 5/64” hexagon Allen wrench.
c. Install the SIM card with the gold contacts facing down and the cut-out facing to the right.
d. The GX400/440 also includes a SIM lock-down feature to prevent the SIM from moving during extreme vibration. The cover has a tab to mechanically secure the SIM in place during extreme vibration. When replacing the cover, first place the front into the lip and push back to make sure the four holes are aligned before screwing the bolts back in place.

6. What size SIM does the GX400 and GX440 use?
a. Both the SIM enabled versions of the device (GX400 for HSPA+ and GX440 for LTE) use a standard size SIM, which is 2FF.

7. Can I get a Static IP for the GX440 on the VZW LTE network?
a. Yes, you can get a static IP on the VZW LTE network by working with your VZW representative or reseller.

8. Does the GX440 LTE device require that an APN be entered into it to gain network access?
a. No. While the GX440 LTE devices does use an APN, that APN will be automatically loaded into the device by the Verizon Wireless network at time of initial device provisioning.

9. What is an MEID?
a. MEID (Mobile Equipment Identifier) is the equivalent to an ESN and is now used by Verizon Wireless instead of the ESN for LTE devices. The MEID is printed on the bottom label of the GX440.
b. IMEI, MEID and ESN are the same.

Network FAQs

10. Which LTE frequencies do the GX440 support for Verizon and AT&T?
a. Verizon: Band 13 – UL 777-787Mhz, DL 746-756Mhz
b. AT&T (future product): Band 17 – UL 704-716Mhz, DL 734-746Mhz (also Band 1 and Band 4 used outside the US)
c. GX440 supports Verizon OR AT&T LTE frequencies, different embedded modules are required for Verizon and AT&T, therefore, there will be two distinct GX440 SKUs
d. GX440 does NOT support public safety Band 14 (D block) – UL 788-798Mhz, DL 758-768Mhz

11. What are the typical downlink and uplink speeds I should expect on the GX440 when it is connected to the Verizon Wireless LTE network?
a. Speed is extremely dependent on network loading and quality of signal, but in testing Sierra Wireless has seen uplink speeds ranging from 5MBs to 10MBs and higher and downlink speeds from 10MBs to 20MBs and higher. Actual results will vary as a result of several conditions.

12. Will the GX440 LTE device support fallback to 3G (EVDO) and 2G (1xRTT) networks?
a. Yes, the GX440 fully supports fallback to 3G and 2G networks. The default setting for the GX440, when it comes to network service preference, is “LTE Preferred”, meaning the GX440 will always look to connect to a LTE service first, if available. If LTE service is not available, then the GX440 will connect to the next fastest service available.
b. For customers who purchase the GX440, but who do not yet have LTE service in their area, there is a configuration option under the “WAN/Cellular” tab in ACEmanager 4.0 to set the GX440 to “CDMA Only”. When this configuration is used the GX440 will not actively scan for LTE service.

Hardware FAQs

13. Both the GX400 and GX440 have 2 SMA connectors for RF antennas. Is it necessary for me to use both?
a. The additional antenna port on the GX400 (EVDO and HSPA+) are for Rx Diversity. Rx Diversity is designed to improve the quality of the downlink signal by essentially enabling the device to “choose” the best available signal. Rx diversity has been shown to improve signal quality. However, many customers decide to forego the expense of the 2nd antenna and rely on one Rx signal. Rx Diversity is set to “ON” by default in ALEOS, but if you decide to not use a 2nd antenna it’s vital to change the ALEOS setting for Rx Diversity to “OFF”. This setting can be found under the “WAN/Cellular” tab in ACEmanager 4.0.
b. The GX440 (LTE) utilizes 2x2 MIMO technology. MIMO equals Multi-In/Multi-out and is designed to improve the cellular signal and quality on both the down-link and up-link. MIMO for LTE works differently than Rx Diversity in that it utilizes 2 distinct Tx and Rx signals which are intelligently combined to increase throughput where signal multipath is available. MIMO will increase throughput in areas where interference would otherwise cause throughput degradation. Our recommendation is that 2 antennas be used for optimal performance. A single antenna may be used, however with one antenna you will not receive full MIMO benefits and your antenna performance may not be optimized. It is up to the user to determine if two antennas are beneficial, as multi-path is determined by local topology. There is no option to turn MIMO off in the GX440 since MIMO is a requirement of LTE.

14. I understand that the GX400 and GX440 both have an expansion slot. What X-Cards are available today?
a. Yes, both GX devices have an expansion card slot, which will greatly increase the versatility of the platform. As of FEB 2012 Sierra Wireless has not launched any Xcards to support this slot, however in the first half of 2012 we expect to release a WiFi XCard that will enable a WiFi (802.11 b/g/n) hotspot (access point) and support WiFi client mode. Later in 2012 we are targeting the release of 2 additional X-Cards to support additional Ethernet Ports and expanded I/O (inputs and outputs).

15. How will the X-Cards be purchased and installed?
a. There are 2 ways to purchase X-Cards.
i. Pre-installed X-Card in a new GX400 or GX440. When purchased this way, the Xcard will be factory installed, tested and shipped to the customer ready to deploy.
ii. Purchase an X-Card and installation separately for a previously purchased GX400/440. When this method is used, the X-Card must be installed by one of our AirLink Resellers specifically designated for this activity. By leveraging an authorized reseller we can ensure that the installation is done correctly and optimizes the customer experience.

16. The GX400 and GX440 have an IP rating of IP64. What exactly does that mean?
a. IP (Ingress Protection) rating measures the rates and the degrees of protection provided against the intrusion of solid objects (including body parts like hands and fingers), dust, accidental contact, and water in mechanical casings and with electric enclosures. The first number of an IP rating represents the level of protection against “solid particle”, while the second number represents the level of protection against “liquid ingress”.
b. An IP rating of 64 indicates that the GX400/440:
i. 6 for solid particles – “No ingress of dust; complete protection against contact.” 6 is the highest rating for solid particle protection.
ii. 4 for liquid ingress – Splashing Water; “Water splashing against the enclosure from any direction shall have no harmful effect.”
1. Test duration: 5 minutes Water volume: 10 litres per minute
Pressure: 80–100 kN/m²
c. The following table details all levels of IP ratings:
