1. Mobile WiMAX 802.16e The Progress and the Promise Dick Lee
VP Caribbean - General Manager North America
Airspan Networks Inc.
The standard of d or e was a simple naming approach but as many of you know, it was changed. And generating its own confusion.
Much of my information on these slides comes from the WiMAX Forum. I will be adding my perspective along the way.

2. Terms IEEE 802.16 IEEE 802.16 (2004) IEEE 802.16 (2005)

High Throughput packet data radio network
Supports several classes of IP Applications and services based on different usage, mobility and deployment models
Support for customer stations moving at vehicular speeds
Air Interface offers high degree of flexibility and options
Base Station and Sector Handover functions are standardized
The WiMAX forum is committed to providing optimized solutions for Fixed, Nomadic, Portable and Mobile broadband wireless access…
and two versions of WiMAX have been ratified to address the demands for these different types of access.
covers fixed and nomadic access in LOS and NLOS environments based upon Orthogonal Frequency Division Multiplexing as the modulation technique… (OFDM).
covers fixed, nomadic, portable and mobile access, but is optimized for dynamic radio channels. It is an amendment of to include support for handoffs and roaming. The modulation technique used is Scalable Orthogonal Frequency Division Multiplexing Access. (SOFDMA) This is a multi-carrier technique that uses sub-Channelization.
Operators may start with a fixed WiMAX solution and migrate as the market dictates from the fixed to mobile using various strategies such as overlay networks, dual mode customer devices and base station devices with software upgrades where no hardware change is necessary.
It should be noted that the air interface for 2004 and 2005 are not compatible and therefore the requirement for the dual mode customer premise units.

This slide shows the WIMAX Access options which will be available as we progress over the next couple of years. Next year’s CANTO conference will be showcasing some of the portable and mobile devices… and by that time there will be many fixed WiMAX networks operating in the world and possibly, some initial Mobile WIMAX networks as well.
Consumers will be given the choice of solutions such as EVDO, as well as fixed and mobile WiMAX and WiFi combinations --- I also believe the 3G type solutions and the WiMAX solutions will co-exist and be complimentary to each other. The WiMAX advantage is the range of Spectrum which can be utilized and the large Channel Width of 20 MHz.
Mobile WiMAX, though will gain a bandwidth advantage as time moves on…due to advances like Scalable OFDMA, smart antennas etc --- Delivering 30Mb per second to a mobile device with soft handoff is doable in a WiMAX roll out. The applications which the consumer would find compelling requiring this amount of data have not yet emerged --- but Digital TV channelisation delivered to vehicles along highway routes, trains, buses etc may emerge as a killer app. for this type bandwidth. Of course full motion digital video delivered from the network rather than the on board DVD player would also enable full voice and data capabilities to the same user from one network provider.
. In my opinion, spectrum diversity and Scalable Channel Widths up to 20 MHz put the WiMAX architecture ahead of the game to deliver high bandwidth mobile services as future applications roll out.

4. Mobile WiMAX – 802.16e Ratified by IEEE late 2005
WiMAX Forum certified products available late 2006 – 3.5GHz International Broadband Spectrum first choice
General Availability 1st half of 2007
Plan to emerge as a viable competitor to 3G Technologies
Fuelled by deployment of WiBro in South Korea – WiBro is a WiMAX Forum supported Standard
Mobile WiMAX as it is commonly called applies to e or 16 (2005) which was ratified in December 2005.
The WiMAX Forum is still stating that certified products will be available by the end of this year and they have opened a second certification lab in Korea to support this plan… but I feel this may change due to the amount of work required by suppliers to make this happen. AND, System Profiles have yet to be approved by the WiMAX Forum Board.
Both fixed and mobile access define 3.5GHz – as one of the frequencies to be included in the release 1 profiles and this frequency can be used in most places on the planet except the USA.
But, 3.5 GHz is not the optimal frequency to use for Mobility due to the Doppler effect which is inherent to moving vehicles.

Airspan is one of the few suppliers to have product certified by the WiMAX Forum testing lab.
This slide shows those Certification Profiles which include Spectrum and Duplexing and Channel Widths used in the certification process. Certification has happened in both the 3.5 GHz TDD and FDD profiles using 3.5 MHz channels and work is continuing towards certification in the 3.5 GHz, 7 MHz channel widths for both TDD and FDD and in the 5.8 GHz, 10 MHz profiles.
Some manufacturers are actually by-passing the Fixed WiMAX round all together – opting to jump into the market only with Mobile WiMAX products. In my opinion fixed WiMAX has many long term applications such as high capacity backhaul for Cellular and WiMAX end-users.
Also, Airspan is providing an upgrade path from Fixed to Mobile WiMAX without a hardware change out by using Software Defined Radio technology available from picoChip.

The IEEE (2005) standard was ratified in December 2005.
A key technology built into this standard is Scalable Orthogonal Frequency Division Multiple Access (SOFDMA) which improves multi-path performance for NLOS environments.
Although SOFDMA can support channel bandwidths from 1.25 to 20 MHz, Release 1 profiles will only allow 5MHz, 7 MHz, 8.75 MHz and 10 MHz channel bandwidths as shown for 2.3 GHz, 2.5 GHz and 3.5 GHz.
Practically speaking, certified mobile WiMAX products should be available by the end of 2007.

Here is a frequency variant from those currently approved that Airspan is deploying today in Tokyo at 4.9GHz.
A real life example of the start of WiMAX and WiFi network interconnection can be seen in Hong Kong implemented by Yozan. This $46 Million dollar project is using Airspan WiMAX and WiFi devices… allows home, Corporate and Mobile clients access to Internet, voice and video services. In this slide we see the large wireless access footprint provided by the Airspan MicroMAX software defined radio and the smaller WiFi footprint provided off of light poles and in homes, offices and vehicles by the EasyST, and ProST devices connected to the Public Domain backbone via WiMAX and connected to the end user via WiFi.
The whole network plan is based upon an upgrade to the “e” (or 2005) standard by early 2008.

10. Strategic Questions… Will Fixed WiMAX Quickly Become Obsolete?
Should Operators start with Fixed WiMAX
Can Mobile WiMAX compete successfully with the Cellular technologies for Data Services?
And so, let me close by posing a number of strategic questions that any carrier will want to consider before deploying WiMAX. Airspan stands ready to assist.
In my opinion Fixed WiMAX will not quickly become obsolete for a couple of reasons --- First of all operators can purchase Fixed WiMAX technology and upgrade to Mobile as the market demands by changing out the software and adding dual mode devices CPE where required… Airspan can run a Fixed WiMAX and a Mobile WiMAX solution from the same base radio station location. In this case some customers will continue with Fixed WiMAX only using it in a home or office environment. Secondly, Fixed WiMAX is an excellent and cost effective solution for both Cellular and WiMAX data services.
Should Operators start with Fixed WiMAX – this is a question which will be answered by the particular business case the operator is running. Incumbents usually have a solid base of Cellular access, and technologies such as EVDO makes sense due to the incremental cost on the existing infrastructure – New entrants who want to compete in the VoIP and data services can start with Fixed WiMAX and upgrade the software of the base stations when mobile WIMAX makes sense in the market. Having a strategic plan which includes an overlay network for fixed and mobile customers is cost effective and future proof.
Can mobile WiMAX compete successfully with Cellular technologies for data services – Absolutely – and the strategy of bringing Mobile WiMAX in, will reduce future risk due to the data capacities and standard protocols that will be available for future end user devices. WiMAX offers greater spectrum diversity, larger channel widths and the benefit of SOFDMA and other advances.
Fixed and Mobile WiMAX can provide a better business case and the case will continue to improve as the price of CPE equipment is reduced due to multiple choices for standard equipment.
Couple the advantages of WiMAX with the ubiquity of WiFi and a winning combination for both voice and data services can be obtained.
