900 MHz Yagis from ZDA Communications – Affordable Quality

ZDA Communications is a relative new comer to the yagi antenna market but have made quite an impression.  With excellent build quality, low cost and ability to be used in either vertical or horizontal polarities the ZDA Communications yagis are the antennas of choice for Motorola Canopy, RFID, SCADA or NLOS broadband applications.

Motorola PMP 320 Typical Tower Build

Here is a bill of materials for a typical Motorola PMP 320 tower build (cluster).

  • 4 x 3630APC (3.65 Ghz 802.16e Wimax Access Point w/ 90 degree sector)
  • 1 x 1090CKBA (CMM4 w/ ruggedized switch and GPS module)
  • 1 x 200SSB (DC surge suppressor for CMM)
  • 1 x SGPN4076 (56 VDC power supply for CMM4)







The Broadband Expo : A Great Success

Canopy PMP 430: Motorola Increases Cluster Capacity to 180 Mbps

The Motorola PMP 430 builds on the success of the original PMP 400 Canopy OFDM platform released last year. The PMP 430 uses the same OFDM radio as the 400 but allows for a total per access point aggregate throughput of 45Mbps instead of 21 Mbps. This jump in throughput is achieved by doubling the channel bandwidth from 10Mhz (PMP 400) to 20 Mhz. However for those who are not keen on using up all that airspace the PMP 430 is rather agile and allows the operator to drop back to a 10MHz channel where needed. Like it’s predecessors, the PMP 430 is deployed in clusters of four access points using 90 degree sector antennas and GPS Synchronization to mitigate self interference, allow for a organic growth of the broadband network and increase cluster capacity to 180 Mbps.

The PMP 430 also comes with a variety of subscriber module choices allowing operators to “pay as they grow”. This allows them to scale the platform to meet the specific needs of their project requirements and budgetary restrictions. The SMs come in the following throughput 10, 20, 40 Mbps. The 10 and 20 Mbps SMs can be upgraded to 40 Mbps in one or two steps by simply purchasing a new license pack (no need to replace hardware!).

The PMP 430 is ideal for high throughput video surveillance applications.

Canopy PMP 430 Access Point:

PMP 430 Subscriber Modules

Canopy PMP 430 Subscriber Bulk Packs

Canopy PMP 430 SM Upgrades

PMP 400/430 Accessories

Note: Keep in mind of course that when using the 10MHz channel the PMP 430 access point has a maximum aggregate throughput of 21 Mbps not 45.

Motorola to Release 802.16e Fixed Wimax, PMP 320

The Motorola wireless broadband Point-to-Multipoint (PMP) 320 is a low-cost fixed licensed outdoor distribution and access solution that delivers fast, affordable connectivity in a variety of environments and applications.

Around the world, service providers and enterprises that hold licensed spectrum in the 3 GHz band are investigating deploying 802.16e WiMAX to provide reliable, cost-effective data, voice and video connectivity for business and residential customers. There is a significant investment required for equipment and installation of a full mobile WiMAX network, with many providers finding it difficult to build a business case for reaching subscribers in low-density locations at the edge of their networks or for building a new network in a low-density greenfield environment that only requires reliable fixed connectivity. The Motorola PMP 320 changes all that. The PMP 320 offers a fixed, outdoor solution that is easy to deploy and does not require the significant investment in core network equipment associated with mobile connectivity.

This is perfect for WISPs, Local Government entities who want to use a licensed spectrum for surveillance deployments and more.

Licensed Spectrum. The fixed outdoor PMP 320 solution is designed to allow service providers around the globe to combine the reliability of licensed bands and standards based equipment with an overall low total cost of ownership. The PMP 320 delivers low-cost, high-performance solutions for operators holding licenses in three different frequency ranges: 3.3-3.4 GHz, 3.4-3.6 GHz and 3.6-3.8 GHz. The PMP 320 supports standard WiMAX QoS profiles.

Standards Based. The PMP 320 is interoperable with WiMAX 802.16e CPEs, supports all of the WiMAX QoS profiles, and uses standard AAA/RADIUS servers for authentication.

Performance. With 2×2 MIMO, 10 MHz channels, and 802.16e coding/error correction the PMP 320 delivers high throughput with excellent coverage and link budgets.
