2.2 Motorola PMP 400 and PMP 430 Products

The PMP 430 operates in the 5.4 GHz and 5.8 GHz frequency bands. The PMP 430 is equipped with OFDM technology to deliver outstanding throughput, long range and line of sight (LOS) and near-line of sight (nLOS) performance for reliable and secure data, voice and video connectivity. The PMP 430 provides more than 40 Mbps of total aggregate throughput per Access Point (AP) sector to difficult-to-reach locations, including multipath urban or rural areas. The PMP 430 provides extended ranges of up to 40 miles (64 km) when the Subscriber Module (SM) is configured with a passive LENS or reflector. The PMP 430 also offers low one-way latency of less than 3.5 msec for sensitive voice and video services. SMs can be upgraded from 4 Mbps throughput to 40 Mbps via a software key system to meet customers' growing need for bandwidth.

2.3 Redline RedAccess Products

The AN-80i is the latest addition to Redline's RedCONNEX family of high performance wireless broadband transport solutions. Delivering carrier-grade performance and reliability that carriers and other service providers have come to expect from Redline's wireless access and backhaul products, the AN-80i is the ideal solution for quickly establishing point-to-point and point-to-multipoint links that cost-effectively extend networks to reach more customers.

2.4 802.16d Developed Products (Airspan Redline)

WiMAX, meaning Worldwide Interoperability for Microwave Access, is a telecommunications technology that provides wireless transmission of data using a variety of transmission modes, from point-to-multipoint links to portable and fully mobile internet access. The technology provides up to 10 Mbit/s broadband speed without the need for cables. The technology is based on the IEEE 802.16 standard (also called Broadband Wireless Access). The name "WiMAX" was created by the WiMAX Forum, which was formed in June 2001 to promote conformity and interoperability of the standard. The forum describes WiMAX as "a standards-based technology enabling the delivery of last mile wireless broadband access as an alternative to cable and DSL".

The 802.16e standard essentially standardizes 2 aspects of the air interface - the physical layer (PHY) and the Media Access Control layer (MAC).

(an amendment to IEEE 802.1D)

IEEE 802.16e-2005 improves upon IEEE 802.16-2004 by:

Adding support for mobility (soft and hard handover between base stations). This is seen as one of the most important aspects of 802.16e-2005, and is the very basis of 'Mobile WiMAX'.

Scaling of the Fast Fourier transform (FFT) to the channel bandwidth in order to keep the carrier spacing constant across different channel bandwidths (typically 1.25 MHz, 5 MHz, 10 MHz or 20 MHz). Constant carrier spacing results in a higher spectrum efficiency in wide channels, and a cost reduction in narrow channels. Also known as Scalable OFDMA (SOFDMA). Other bands not multiples of 1.25 MHz are defined in the standard, but because the allowed FFT subcarrier numbers are only 128, 512, 1024 and 2048, other frequency bands will not have exactly the same carrier spacing, which might not be optimal for implementations.

3.3 802.16d and 802.16e WiMAX Data Rates

A commonly-held misconception is that WiMAX will deliver 70 Mbit/s over 50 kilometers (~31 miles). In reality, WiMAX can either operate at higher bitrates or over longer distances but not both: operating at the maximum range of 50 km increases bit error rate and thus results in a much lower bitrate. Conversely, reducing the range (to

802.16m system will be able to support both 120 Mbit/s downlink and 60 Mbit/s uplink per site simultaneously. It is expected that the WiMAX Release 2 will be available commercially in the 2011-2012 timeframe

7.10 Product Availability - ManufacturingThis report presents Taiwanese WiMAX CPE shipment volume and value forecast and recent quarter review of shipment volume, value, ASP, shipment ranking, and product mix. The content of this report is based on primary data obtained through interviews with WiMAX CPE makers. This report finds that Taiwanese WiMAX CPE shipment volume saw significant growth in the second quarter of 2009, recording a sequential growth rate of 96.0%. Although ASP has been on the decline, shipment value saw rapid growth on climbing shipment volume. In terms of product technology, 802.16e products have become the mainstream shipment, while shipment share of 802.16d products continued to shrink. It is forecasted that Taiwanese WiMAX CPE shipment volume will see continuous growth in the following quarters, with the full-year 2009 shipment

volume projected at two million units.

Mbit/s mobile & 1 Gbit/s fixed in progress

The IEEE 802.16m standard is the core technology for the proposed Mobile WiMAX Release 2, which enables more efficient, faster, and more converged data communications. The IEEE 802.16m standard has been submitted to the ITU for IMT-Advanced standardization. IEEE 802.16m is one of the major candidates for IMT-Advanced technologies by ITU. Among many enhancements, IEEE 802.16m systems can provide four times faster data speed than the current Mobile WiMAX Release 1 based on IEEE 802.16e technology.

Mobile WiMAX Release 2 will provide strong backward compatibility with Release 1 solutions. It will allow current Mobile WiMAX operators to migrate their Release 1 solutions to Release 2 by upgrading channel cards or software of their systems. Also, the subscribers who use currently available Mobile WiMAX devices can communicate with new Mobile WiMAX Release 2 systems without difficulty.

It is anticipated that in a practical deployment, using 4X2 MIMO in the urban microcell scenario with only a single 20 MHz TDD channel available system wide, the 802.16m system can support both 120 Mbit/s downlink and 60 Mbit/s uplink per site simultaneously. It is expected that the WiMAX Release 2 will be available commercially in the 2011-2012 timeframe.

The goal for the long-term evolution of WiMAX is to achieve 100 Mbit/s mobile and 1 Gbit/s fixed-nomadic bandwidth as set by ITU for 4G NGMN (Next Generation Mobile Network).

9.0 Conclusion

9.1 Data Rate:

For ADSL2 and small symmetrical accounts 802.16d and 802.16e will deliver a good service.

Equipment for PMP Symmetric services, Motorola Canopy and RedAccess products offer larger symmetrical possibilities.

9.2 Coverage:

The systems reviewed, only the Motorola 802.16e units have a wireless range less than 20km. Most of the other systems seem to be able to transmit over a 20km area, before running into RF issues.

9.3 Scalability and Upgradable:

The 802.16e technology seems to be the most scalability and upgradable. Due to the varied products available, current development and a upgrade path in the future.

The 802.16d, Motorola Canopy and RedAccess products will probably not be developed to much further and are mature products.

9.4 Usability and Training:

Training for all the reviewed equipment is available.

9.5 Overall Conclusion

ADSL type services:I recommend deploying 802.16d equipment at the moment. The equipment is cheap, plentiful. Engineers with experience on the 802.16d platforms are more available due to the technology being on the market for over 3 years. ADSL2 type services:

I recommend deploying 802.16e equipment at the moment. To review up coming 802.16m equipment for near future deployments, especially in the high density urban areas.

Symmetric type services:I recommend deploying Redline RedConnex products for larger symmetrical services. (larger than 5/5meg) . 802.16m could have a roll to play in servicing these customers in the future.
