| 87 | | [http://www.doodlelabs.com/ Doodlelabs] creates frequency shifting modules to allow frequencies between 700MHz - 6.5GHz, while using standard linux drivers. These systems are comprised of one ath9k/ath10k radio with a FES module on each chain. The below picture will help visualize this: |
| 88 | | |
| 89 | | [[Image(Prism-FES-1.png, 256px)]] |
| 90 | | |
| 91 | | In this system, a radio has two separate FES modules per chain. From the factory, Doodlelabs calibrates each chain on a specific radio to a particular FES module. This means that a radio with 2 chains is specifically paired with two FES modules. You can find which FES modules are paired with what radio by comparing serial numbers (Hint: all components in the system have the same serial). It's very highly recommended by Doodlelabs that nothing is mixed and matched. |
| 92 | | |
| 93 | | Radio's configured to be used in a Prism-FES all have EEPROM values programmed in to only allow a maximum of 10dBm output (per chain). '''Anything higher will damage the frequency translator'''. For this reason, Prism-FES's that are using ath10k are '''recommended to stay away from using the STA firmware (999.999.0.636)''' as we found that this firmware does not honor the EEPROM settings and configures the radio to output much higher than 10dBm. |
| 94 | | |
| 95 | | ''' FES Power Discussion ''' |
| 96 | | |
| 97 | | For example, the GW6100 can support approximately 8W of power to the Mini-PCIe slot (at 3.3V). |
| 98 | | |
| 99 | | The Doodle Labs radio requires around 2W for the radio portion which should work fine in the Mini-PCIe site. |
| 100 | | |
| 101 | | For the FES amplifier you will need and additional 16W of power which would be over the limit of what we can provide from the slot. |
| 102 | | |
| 103 | | Doodle Labs does however have an optional DC/DC converter (6-38V input) which can be used to power the FES directly from your VIN supply. See the following link for picture of the DC/DC: https://doodlelabs.com/products/industrial-wifi-transceivers/datasheet-nm-5500-2f/ |
| 104 | | |
| 105 | | By using the optional DC/DC you can also mount the FES away from the board to optimize your thermal solution. The FES is pretty small and generates a lot of heat so I would suggest mounting it directly to your enclosure for maximum heat transfer and then you can cable from the radio to the FES. |
| 106 | | |
| 107 | | If the Doodle Labs DC/DC doesn't fit your design needs there are lots of other vendors that make DC/DC modules that you could use for the FES power. As an example see the following link: https://www.cui.com/product/resource/pyb20-u.pdf |
| 108 | | |
| 109 | | ==== Part Numbering Scheme ==== |
| 110 | | Before we break this down further, the following terminology used by Doodlelabs is required: |
| 111 | | |
| 112 | | Grade Breakdown: |
| 113 | | * Military Grade - This is their Industrial grade option. This grade has extended temp of -40C - +85C. This grade also has antenna port protection, and is built to a higher standard than their other radio's. |
| 114 | | * Enterprise - This is their Indoor Commercial grade option. This grade has a temperature range of 0C - +60C and has no antenna port protection. |
| 115 | | * Outdoors - This is their Outdoor Commercial grade option. This grade has a temperature range of -40C - +40C and has antenna port protection. |
| 116 | | |
| 117 | | The model number NM-770-2F is broken down into three sections: NM, 770, 2F |
| 118 | | |
| 119 | | * '''NM''' - The 'N' refers to this being an 80211N radio. If this were 'ACM', for example, that would mean the radio is a 80211AC radio. The last character of the first section refers to the grade the radio is. In this case, the 'M' stands for Military, or rugged, grade. |
| 120 | | * '''770''' - This number refers to the middle frequency of the frequency range that the card supports. In this case, the card supports 746~798, the midpoint center frequency resulting in 770. If there is no number, and instead has either 'DB' or 'TB', that only means "Dual-Band" and "Tri-Band", respectively. When DB is specified, that refers to both the 2.4GHz and 5.8GHz range. TB refers to DB, but also includes the 4.9GHz frequency range. |
| 121 | | * '''2F''' - The number '2' refers to the number of chains the radio has. In this case, there are two chains on this radio. A '3' would indicate three chains. The 'F' alludes to the fact that each chain get's frequency shifted through the frequency shifting module. This means that you're always going to have a FES module per chain. |
| 122 | | |
| 123 | | So in conclusion, the NM-770-2F system includes a 80211N radio with two chains, each getting frequency shifted by a FES module to the 770MHz range. |
| 124 | | |
| 125 | | ==== Licensed vs Unlicensed ==== |
| 126 | | In the US, the difference between Licensed and Unlicensed comes down to how the FCC regulates the frequency spectrum. In general, Doodlelabs refers to 'unlicensed' radio's the 2.4GHz and 5GHz range frequencies. All other frequencies fall under being 'licensed'. |
