Upgrade from PTP800/810 radio to PTP820

I will start a new discussion here talk about how to upgrade an existing PTP800/810 links to PTP820. If you have a deployment today using PTP800 or PTP810, you are welcome to join this discussion. 

Obviously, the PTP820 support 2048QAM, which will bring higher capacity compare to PTP800/810 which use 256QAM, but how about system gain and other factors? 

I would like to show you a table on 11GHz @ 40MHz first, then we will take a deeper dive on this topic in the next few days.

with +6 dB gain compare to PTP800, customer will see link availability improvement when they swap to PTP820. A good starting point !! more details to be followed.

Here list all major beneifits upgrade from PTP800/810 to PTP820.

1. Improvemnet of radio throughput, as PTP820 support up to 2048 QAM

2. Improvement of Link Availability, as PTP820 provide better system gain compare to PTP800/810 given same modulations

3. Improvement on power efficiency, as PTP820 takes half of the power consumption compare to PTP800/810

I will try to cover 1+0 configuration first here, which means in most case you are replacing your PTP800/810 to PTP820S (full outdoor) or PTP820G.

Option a: Upgrade 1+0 PTP800/810 to PTP820S

What you need:

- PTP820S radio

- Since PTP820S is full outdoor, we change from coax cable to CAT5E cable, so you will need all accessories needed for a proper installation of PTP820S. (Llinkplanner can help give you the BOM)

- Antenna is re-usable, but we will need chagne the VINTA and convert it from PTP800/810 to PTP820 direct mount. (Only Andrew Valu-line dish can be converted, details please check your RSM/RTM).

Tip:

WHen you choose the radio, you will need compare the T/R and more importantantly the Frequency range. Here i use FCC 11 GHz to  show a map relationship:

PTP 800 ODU  Tx Low                   Tx High                ==>  PTP 820S      Tx Low                  Tx High
B5 10700.0 ‐ 10890.0 MHz 11200.0 ‐ 11390.0 MHz ==> Ch1W6 10695‐10955MHz 11185‐11485MHz
B6 10855.0 ‐ 11045.0 MHz 11355.0 ‐ 11545.0 MHz ==> Ch4W9 10815‐11095MHz 11305‐11585MHz
B7 11010.0 ‐ 11200.0 MHz 11510.0 ‐ 11700.0 MHz ==> Ch7W13 10915‐11207MHz 11425‐11725MHz

For Example:

01010208001 ODU‐A 11GHz, TR 490 & 500, Lo, B5 (10700.0 ‐ 10890.0 MHz), Rectangular WG, Neg Pol
01010208002 ODU‐A 11GHz, TR 490 & 500, Hi, B5 (11200.0 ‐ 11390.0 MHz), Rectangular WG, Neg Pol

can be replaced with 

C110082B001A PTP 820S Radio 11GHz,TR500,Ch1W6,Hi,11185‐11485MHz
C110082B002A PTP 820S Radio 11GHz,TR500,Ch1W6,Lo,10695‐10955MHz

Have a great thanksgiving week

Can you please clarify the statement:

- Antenna is re-usable, but we will need chagne the VINTA and convert it from PTP800/810 to PTP820 direct mount. (Only Andrew Valu-line dish can be converted, details please check your RSM/RTM).

I am not sure what a "VINTA" is.  I have an application where we are trying to convert a PTP11800 to the PTP820 and want to make sure that I can in fact direct mount these.  

The "VINTA" plate is the piece of metal between the antenna and the ODU that allows a direct mount.

If you have Andrew ValuLine antennas, you can replace the PTP 800-compatible VINTA plate with a PTP 820-compatible VINTA plate that allows a direct mount for PTP 820.

I hope this helps!

Can I connect a PTP-800 on one end to the PTP-820 on the other end?  We have an application with multiple PTP-800s installed at multiple fixed sites communicating to PTP-800s on mobile platforms.  We want to get more PTP-800s to cover the rest of our mobile platforms, but found out that the PTP-800 is no longer manufactured and support by Cambium. 

Unfortunately, a link will not work with a PTP 800 ODU at one end and a PTP 820 ODU at the other end. They are not compatible.

However, there are many ways to upgrade a PTP 800 or PTP 810 link to PTP 820, without replacing the entire set of gear. (That's how this post started!)

If you need help upgrading a link without replacing the antennas (or antennas and waveguide), please contact a Cambium Networks Regional Sales Manager (RMS) or Regional Technical Manager (RTM), and they'll help you through your specific challenges.

There are many antenna vendors that our products support. Often it's just a matter of removing the ODU, replacing the antenna plate (with a PTP 820 compatible adapter), and adding the PTP 820 gear!

If you don't know who your RSM or RTM is, feel free to respond on the forum and I'll help you find the right people to help you!

I hope this helps!

I tried to reach out via phone today but didn’t get an answer. I have a VHLP6-6W dish that has a PTP800 on it. I need to change to a PTP820S so what is the part number for the VINTA plate? What all do I need to change to make this conversion?

Hi Matthew,

The VINTA plate part number is:
N060082L004A - PTP 820 Andrew Valuline Antenna Convert kit, 6GHz

You may also require the following:
N060082L217A - PTP820 REMEC interface Antenna Adaptor Kit, 6 GHz, Single Pol

Please do reach out to your local RTM/RSM for more information. If you don’t know how to get in touch with them, please email linkplanner@cambiumnetworks.com with your location details and we will put you in touch with the right people.

Regards,
Rachel
