Q1. Does it support POE? If so, is the POE 802.11af, 802.11at or a proprietary format?

A1: Like all PMP radios, the PoE scheme is proprietary.

Q2. How much power does the radio use & at what voltage? A2:The PTP230 uses a maximum of 10W at 30V input (power supply part numbers ACPSSW-13B or infrastructure grade ACPSSW-20A).

Q3. If it supports POE, is the distance the same at the Cat5e data cable standard? A3: The cable length is limited to 100m (330 ft).  Yes, the standard.

Q4. What kind of mounting? What size pipe can the radio mount on? A4. In the US, the PTP230 is sold with the mounting kit (SMMB1A) which includes a 1" diameter pipe.  The radio can be mounted on other diameter pipes as well by simply strapping the bracket to the pipe.  Successful customer deployments have been demonstrated on pipes from 1" to 24" O.D.

Q5. Is there a chart or table that shows the relationship of the modulation rate, RSL, SNR and throughput? A5.

Q6. Can the radio be configured with a web browser? Does it support telnet? A6. All PMP radios utilize a web-based GUI as the main interface.  SNMPv2 is supported for scripting and command line interface to the radio.

Q7. Is modulation dynamic? A7. Yes, modulation is dynamic.

Q8. Can symmetry be adjusted? A8. Yes, uplink/downlink ratio is configurable from 15/85 to 85/15.

Q9. When two links are used as a repeater, does the symmetry have to be 50-50?

A9. No,each link is configurable.  Proper network planning should be used to ensure best performance.

Q10. Does the CMM work and how is it cabled? A10. Yes, PTP230 can be powered and synchronized with CMM3, CMM4 or UGPS.  All PMP radios use the single RJ-45 data cable for power, data and gps synchronization via a CMM.  Alternatively, using a UGPS, the 6-pin RJ-11 timing port and cable is utilized.  The PTP230 will also power the UGPS device directly from the radio without requiring a separate power source for the UGPS.

Q11. Will there be a 5.4GHz version? A11. Yes, release for this version is planned for early Q3, 2011.

Q12.  Is there any way to improve my link budget? A12. Yes, adding a LENS (AN500A) will add 6 dBi to the integrated patch antenna (10dBi) and narrow your beamwidth to 18 degrees.  Or adding a reflector dish (27RDD) will add 15 dBi gain, and narrow the beamwidth to 6 degrees.  These may be used in any situation where enhanced link budget is required.
