WiMax and Mobile WiMax
Hello WiMax360 Readers: I plan to post my thoughts on where I think WiMax may apply bsed on my past field experience of installing real Point to Point, Point to Multipoint fixed wireless networks, & WLAN networks for "wireless access" in the public and private enterprise space; including involvement with traditional integraed voice and data radio (RF) systems; commonly referred to as two way radio; and 802.11(_) systems;commonly referred to as "muni WiFi systems". I took in-depth technica

* GE Energy's next-generation WiMAX SmartMeter products, which integrate Grid Net's PolicyNet firmware, and the Intel[R] WiMAX Connection 2250 and Intel[R] WIMAX Connection 2400 chipsets (formerly codenamed Baxter Peak).
"Implementing the Smart Grid requires a truly open approach, using the best products and technology," states Ray Bell, founder and CEO of Grid Net. "Our focus is all about offering utilities a broader choice of better solutions, at lower costs. That's why we're pleased to collaborate with Intel and with GE Energy, and to leverage the ongoing innovations of more than 500 leading WiMAX technology providers into a Smart Grid ecosystem of open standards-based communications, utility transmission and distribution automation, and advanced metering products and technologies."
"The deployment of Smart Grid solutions addresses the issues of a growing population and climate change by increasing the productivity, reliability, and efficiency of our current electrical power grid. In addition, these technologies will empower the consumer to manage their electricity spend and usage, which will enable all consumers to become a part of solving the energy challenge now facing our planet," says Bob Gilligan, general manager of Transmission & Distribution. "At GE Energy, we have made a choice to be actively engaged in developing these technologies to meet this challenge."
"WiMAX will enable innovative applications for a variety of industries," said Sriram Viswanathan, vice president, Intel Capital and general manager, Intel WiMAX Program Office. "Grid Net and GE's Smart Grid solution is a brilliant example of what we can expect from solutions built with WiMAX technology's performance, cost-effectiveness and standards-based, open architecture."
Smart Grids Require Truly Open Solutions
Grid Net is catalyzing an ecosystem of providers who believe that the optimal technology for implementing and managing the Smart Grid should be
* Built on open standards and protocols, so that utilities can choose the most innovative and cost effective solutions, and avoid "single vendor, proprietary product lock-in" seen in other solutions
* High performing and scalable, in order to cost-effectively manage tens of millions of customer energy service delivery points, meters, and other distribution automation devices
* Integrated, interoperable and optimized, to leverage innovations from all technology and product providers, the Smart Grid solution ecosystem of vendors, customers, and standards groups
* Resilient and adaptive, so that the Smart Grid can self-heal points of failure, or provision new services rapidly and cost-effectively - self-healing, self-provisioning, and self-optimizing
* Secure and reliable, so that Smart Grid devices and services are well protected, and meet both governmental and industry Smart Grid security specifications, guidelines, and recommendations

How are you doing? Couple of days back i went through your case study on WiMAX monitoring systems and that was inspiring. It is both informative and useful.
Given a scenario, what is the flow-chart model that you follow (as in your basic procedure that you put to test) and is a skeleton for every case-study you come across? (it has to be common for all right?)
Can you share your thoughts on this or share your Prac Experience Library (case studies etc)? that is if you have all of it gathered up...
As an RF network designer i am just looking for some hardcore WISP case-studies or useful tips that can widen my thinking and sense of innovation...Thanks!!

Hi Naafay, I received your message and you have great observations. You are correct that many pre-WiMax systems (Motorola Canopy and Orthogon, Expediance), (Alvarions), etc. are delivering good bandwidths now. Many WiSPs in my area are completely content with the services they provide over existing private Fixed Wireless Systems in delivering ethernet access or public WiFi 802.11. For example, the Point to Multipoint available now deliver up to 14 Mbs with GPS sycnching and an Element Management System. I installed a couple last year in my areas near Silicon Valley. And many of my municipal customers are using pre-WiMax "fixed wireless" to extend fiber to rural areas. Typical Point to Point in 300 Mbs up to 30-40 miles is about $20K (two radio tranceivers) in my area. However they are FIXED systems. NOT MOBILE. That is the big difference. I see more clients asking for MOBILITY and that is where I see the Mobile WiMax 802.16(e) standard as the main differntiator. For example, one city manager thinks the Public WiFi 802.11(g) will give "mobilility" to his policemen who need to check email while they walk their downtown areas. Is this really true? What is mobility in the 802.11 standard? If you think about it the 802.11 standard can give you "walking" mobility on a laptop but in my opinion it is quite limiting. So I think what I see happening over here is that end-user workers are asking their organisations to give the true mobility with enough bandwidth to do work and things. I will send you my further thoughts and real case studies with numbers. I hope I have provided some prelminary observations, ok?

But we discussed how existing fixed wireless systems provide broadband wireless access and that seems to be adequate for right now. The said the next trend is their WiSPs want to offer IPTV and mobility to their end use customers which verifies my comments above. And they want this at a minimal capital investment.
We concluded that the constraint is not the fiber operators but rather the fixed wireless piece. And it’s not really a constraint but rather the available specification on the 802.11 (we didn’t get into WiMax discussion) protocol in terms of what it can or cannot do with mobility and IPTV. In my meeting with operator we concluded that IPTV needs multicast to meet the "business case" and service packages. The current fixed wireless systems are designed for unicast on the advanced 802.11 protocols. If you read other postings by RF Planners here you will see that the Mobile WiMax 802.16(e) will provide the "mobility" on a "fat client". However I saw one posting yesterday that indicated the 802.16 is still unicast. So you need to verify this. Now let me conclude that for video surveillance and other "Uni" or "one way" applications that you can still do many "IPvideo" applications on the existing fixed wireless systems. I just (my dealer) installed a point to point video surveillance system using Canopy Access point to Subscriber Module connected to a Sony IP Camera. It was a NLOS so we used high gain Yagi antennae. This was a highly forested area and it worked.
Please note my observations are practical in nature and you will need to verify your deployment with an RF Planner. I am trained on Orthogon Point to Point, Canopy Point to Multipoint, Mesh, and experienced in utility systems. My buddy has a company called Integrity Networks here in California and he uses Apertos gear
