How Proxim Wireless is Innovating PtP and PtMP Radio Systems


Innovating the next generation standards in PtP and PtMP segment, Proxim Wireless Corporation, a global provider of advanced Wi-Fi, point to point (PtP) and point to multipoint (PtMP) radio systems, has recently launched – ‘Tsunami WORP Sync’, the latest release of Proxim’s proprietary Wireless Optimized Routing Protocol (WORP) software.

This latest generation of WORP software adds two important features to the already-powerful suite of benefits enabled by Proxim’s WORP software:
Network synchronization
Common Timing Protocols (CTP) enabling interference-free operation even in certain multi-vendor equipment environments

Network Synchronization

With the growing demand for outdoor wireless applications and limited license-free spectrum, there exists a clear and growing deficit of available interference-free frequencies. Large scale wireless Internet service providers (ISPs) and organizations with dense networks are compelled to reuse the limited available spectrum, often resulting in high self-interference, poor Quality of Service (QoS), and reduced throughput.

Proxim’s WORP Sync technology effectively overcomes these challenges by harmonizing all Proxim WORP Sync-enabled PtMP base station units (BSUs) and PtP radios in a network to either transmit or receive at the exact same time with the help of GPS satellite signals or other Ethernet timing devices.

This WORP Sync harmonization results in:

Reduced self-interference and improved consistent, high throughput performance
Augmented with the WORP Sync features, Proxim’s proprietary WORP® MAC technology virtually eliminates contending Transmit (TX) and Receive (RX) cycles from nearby peer Proxim radios in a network. Reduced self-interference ensures higher throughput, improved BER performance and more consistent and predictable operation even in dense deployment conditions.

Improved over the air efficiency and collocation

Proxim’s WORP Sync technology enables efficient frequency reuse and dense collocation. Leveraging the advantage of reduced self-interference, more WORP Sync-enabled BSUs and PtP radios can be collocated more efficiently on the same cell site with fewer channels and without affecting the performance of the network. Denser collocation in turn enables network operators to increase their Bits/square mile from a single tower.

Common Timing Protocol for Multi-Vendor Equipment Environments

The WORP Sync technology provides the benefits described above in greenfield deployments – new deployments of just Proxim radios. However, Proxim realizes that network operators who previously deployed radios from a different vendor often want to switch to Proxim radios. Deploying Proxim radios in a network that uses equipment from other vendors can lead to interference between the two brands of equipment with resulting decline in overall network performance.

“We wanted to continue our history of developing our WORP technology to enable real-work advantages and choices for our customers. While I am proud of our introduction of a GPS synchronized wireless communications platform, I am very proud of our Common Timing Protocol enabling our products to co-exist within third party vendor networks. Now network operators can begin to enjoy the benefits of synchronized multi-vendor networks. While of course other vendors could change their products to prevent this peaceful co-existence, we don’t believe that is in the best interests of network operators so trust these changes will not occur. We would welcome the opportunity to discuss this peaceful co-existence issue with other vendors to continue to expand the choices available for network operators,” said Lee Gopadze, President & CEO, Proxim Wireless.
