TDMA limitations TDMA limitations and upgrade procedure from "
MINT" firmware version to "
TDMA".
...
- Supported hardware platforms: H05, H06, H07, H08, H11.
- It works only with MIMO deviceswith MIMO devices.
- "transient" mode is not supported.
- It is recommended to use the same "TDMA" firmware version on all devices in the network.
- All synchronized master devices in sync mode with AUX-ODU-SYNC must have the following equal parameters:
- There are the following conditions of "TDMA" use in various channel width:
- Fully supported: 5, 10, 20, 40 MHz.
- Operates, but there may be minor frame deviations: 3.5, 7, 30 MHz (with "Greenfield").
- Not recommended for use: 14, 15, 30 MHz.
- Fully inoperable: 28 MHz.
- Recommended channel width in PtMP topology: 20 and 40 MHz (this is due to large overhead for the service information transmission in narrow channel width).
...
1) Check the device configuration and ensure that the switch group with SVI is used for access and remote management.
2) On CPE devices enable:
- Automatic transmit power control ("ATPC" option).
In order to do this go to the section "Basic Settings" -> "Link Settings" in web-interface and check the box "Auto":

- Set the maximum possible transmit power in the field "Tx Power".
- Click "Apply".
3) Download beta "TDMA" firmware from the ftp server: ftp://ftp.infinet.ru/pub/Firmware/beta/TDMA/ for the appropriate hardware platform.

All devices after upgrading to "TDMA" version becomes a Slave. The only exception will be a device with the enabled "Polling" option (command "mint pollstart"), which becomes the Master and has the following parameters by default: - Frame Size: 5 ms
- Max Distance: 70 km
- DL/UL ratio: 50% Auto
- STA RSSI: -20 dBm.
After upgrade set the actual value of the "Max. Distance" parameter. |
7) Upgrade the device boot monitor for hardware platform "H08" (R5000-Omx and /R5000-Mmx models) via command.

Information about hardware platform type is available in the section "Maintenance" -> "Firmware". |
| Note |

|
"_upgrade -q" command is available starting with firmware version "MINTv1.90.17". It is recommended to install the firmware version not lower than "MINTv1.90.25" before the boot monitor upgrade. The command can be executed via a web interface in the section "Command Line". |
In order to make sure that the boot monitor has been updated, enter the command.
