Answer: There are three differences between the PTP 650 and PTP 650S:
- The PTP 650S has a smaller form factor (<180 cubic inches) and is sold only in an integrated version with a 19dBi antenna. This small form factor reduces the size and in many cases gets below the ‘de minimis’ requirements of city planners when posting the radio on street furniture such as a lamp post in small-cell backhaul or video surveillance applications. We’ve also introduced some low-profile brackets that simplify mounting on utility poles and light standards.
- PTP 650S comes standard with IEEE1588v2 and Synchronous Ethernet which are used to deliver precise timing for 4G/LTE backhaul applications.
- The PTP 650S specifically targets short-range Line of Sight and Non Line of Sight applications. The PTP 650S leaves the factory with a 2km (1.25mile) range limit and is able to operate up to the full 450Mbps. So you get full capacity out to 1.25 miles. There is a software license key to unlock this to full range.
The standard PTP 650 (available connectorized or with 23dBi integrated) is well-suited for long links and/or when you need external antennas or the high-gain integrated antenna. The radio ships as a LITE capacity level which operates up to 125 Mbps (or 28% of throughput that the RF conditions allow). It can be upgraded to MID/250Mbps or FULL/450Mbps capacity and there is no range limitation.
Everything else is the same.
