Agenda

1) GENI WiMAX site frequencies, for Airspan order: see attached file

2) Consider WiMAX modem orders, including WiMAX USB cards: see attached file

3) Plans at Temple Drexel?

4) Can new Airspan base stations increase range beyond that provided by NEC base stations?

5) Can we use WiMAX to cover campus, per UMass Dartmouth?

GENI WiMAX site frequencies, for Airspan order

New or expanded GENI WiMAX base station installations

Airspan choices:

2510 Lo: 2496 - 2570 MHz

2510 Mid: 2560 - 2630 MHz

2510 Hi: 2620 - 2690 MHz

Each site needs to obtain one or more authorized frequencies in the 2600MHz band:

From an existing Educational Broadband Service license owned by their institution By applying to the FCC for an experimental license By negotiatying with Clearwire to "borrow" frequencies

For those sites that expect to operate two or three sectors from one site, you should get two or three frequencies, so that a Mobile Station on the edge between two sectors is able to see and pick one sector or the other.

For those sites planning to utilize handover, you should get at least two frequencies.

Per Gregg Tome on 12/14/11:

• Both Ethernet and Fiber connections are available on the Air4GW BS.
• The longest Fiber cable we sell is 100M and I would not recommend longer than that.

From Air4G product specifications:

1.3 Fibre Network Interface

Standard: IEEE802.3z Interface Speed: 1000Base-SX for short range Communication Mode: Multi Mode Connector LC

1.4 Ethernet Ports Standard: IEEE802.3 Interface Speed: 100Base-Tx Communication Mode: Full Duplex Fibre and Cable: UTP category 5 or 5E Connector: RJ45 Socket

You may choose the fiber Ethernet interface for easier remote connections, and to reduce concerns about lightning surges entering your server room. If so, you will need:

Two short 2m fiber pigtails, to connect from the LC connectors on the base station to a more-standard ODC connector; these will be included in each base station order to Airspan

Also, you will need to order:

Up to 100m twin-fiber multi-mode cable (orange), with ODC connectors (need additional details) Fiber interface with ODC connector for your Ethernet switch (need additional details)

WiMAX modem orders

Possible new WiMAX modems for use in Spiral 4:

1) Teltonika modems:

1a) UM62x1 USB WiMAX dongles, per your measurements and pending order, $33-55 From Derek Meyer:

I made a wiki page for all to view regarding the USB devices: ​http://groups.geni.net/geni/wiki/WIMXUWI/TeltonikaUM62x1 "Just worked", happy with them. Good RSSI, comparable to Intel 6250 inside laptop Teltonika would customize them Mimo Same chipset as the HTC EVO handset

How To's

Linux

Device will look like a cdrom eject Can use: wget --http-user admin --http-password admin -qO - ​http://192.168.0.1/cgi/cli?[command] See data collection below for how to find a list of commands.

Embedded Linux

Verified working with Openwrt on Routerstation Pro. TODO: Complete kernel module list. Kernel has to be compiled with cdc_ether, scsi cdrom If using Openwrt, compile busybox with eject command or dmesg to find out what the device shows up as:

opkg update

opkg install sdparm sdparm --command=eject /dev/sg? Then use the above Linux tutorial.

Windows

Verified working in Windows 7 64-bit Did not test without installing Teltonika software Install software when prompted to.

Mac OS

Verified working under Lion

Settings After the device is set up, the USB device will appear as a wired Ethernet device with the, dhcp release, IP address of 192.168.0.x.

1. Favorite browser ==> 192.168.0.1

The default username for the administrative interface that we will be using is: Username: admin Password: admin

2. Configure Wimax

Click on WiMAX tab Click on Channels sub-tab Add your base station(s) information

3. Verify connectivity

Note that your settings are stored on the device, so this will only have to be done once for each device.

Data collection & Misc

One tab I would like to point out is the CLI (command line interface) that you can run several commands to collect all kinds of information. A list of commands can be viewed with the help command. Question: Can we modify the firmware?

1b) RUT425 WiMAX router; per their website, this looks like it might be very good for vehicular applications Derek Meyer:

No experience yet

Will order 2 for testing

2) Airspan modems: From Gregg Tome on 12/14/11:

All CPE’s support Windows (USB, IDU’s ODU’s) and we are checking with PLM to see if they support Linux, Open Source.

2a) MiMAX-USB-V15-260 user device (indoor) $120; Ivan intends to purchase x2 per base station From Gregg Tome on 12/14/11:

MiMAX-USB-V15-260 user device (indoor) - USB Device:

• Plug into lap top device.
• Designed to support both Outdoor and indoor signal.
• Supports Windows and we are checking with PLM to see if they support Linux, Open Source.

2b) M-Pro-B-V95-260-I-US user device (outdoor and indoor) $472; Ivan intends to purchase a few From Gregg Tome on 12/14/11:

Pro-B-V95-260-I – Outdoor Device:

• This is an Outdoor CPE that includes an indoor WiFI router and VOIP Ports.
• The Manufacturer of these ODU’s is currently working on a new Version and we have not received the new version yet and I don’t have a timeline from them on when they would be available. Question: Could this be used on a vehicle?

2c) M-PRO-V72-260I-US From Gregg Tome on 12/14/11:

*I recommend the ProV Outdoor unit – MiMAX-Pro V Series 2.5-2.7GHz TDD PN M-PRO-V72-260I-US:

• I have attached the product specs for these and they are excellent.
• They do provide outdoor coverage only. Question: Could this be used on a vehicle?

2d) M-EASY-V35-260I-US $187; Ivan intends to purchase a few

From Gregg Tome on 12/14/11: M-EASY-V35-260I-US – Indoor Device:
