I try to keep a record of my observations of wireless things happening around the world, in particular in Malaysia. My interests are broadband wireless access (BWA), 3G cellular communications, wireless sensor networks and vehicular ad-hoc network (VANET).

WiMax deployment status in Malaysia: 20 July 2006
The Malaysian Communications & Multimedia Commission (MCMC) received 17 submissions for the controversial 2.3GHz broadband wireless access spectrum – commonly known as WiMax – tender exercise but will only evaluate the applications after addressing the concerns of the government.
The MCMC said this in a statement after Energy, Water and Communications Minister Datuk Seri Dr Lim Keng Yaik called for a tender recall, alleging that the commission did not follow the ministry’s specifications for the tender bid.
The 17 applicants was Telekom Malaysia Bhd, Maxis Communications Bhd, MiTV Corp Bhd, DiGi.Com Bhd, NasionCom Sdn Bhd, REDtone-CNX Broadband Sdn Bhd, MIB Comm Sdn Bhd (controlled by Mesdaq Market leader Green Packet Bhd), Jaring Communications Sdn Bhd, Asiaspace dotcom Sdn Bhd, Celcom Timur (Sabah) Sdn Bhd, Fibrecomm Network (M) Sdn Bhd, SGR Capital Sdn Bhd, GO Lightspeed Broadband Sdn Bhd, Bizsurf (M) Sdn Bhd, IP Mobility Sdn Bhd, Optical Communications Engineering Sdn Bhd and Electcoms Wireless Sdn Bhd.
Potential of WiFi Broadband Wireless Access (BWA)
With the introduction of WiFi mesh, I have no doubt that it would definitely promote further the exploitation of WiFi for BWA.
Let's read an anticle on the advantages of using WiFi mesh for provisioning of BWA.
Green Packet's last mile wireless solution
Currently, the only company with last mile connection is Telekom Malaysia Bhd (TM), which owns this facility through its fixed phone lines to homes and offices.
However, Green Packet, a Malaysian high tech company, will soon offer competition to TM’s Streamyx Internet service. The company has developed a product called SONmetro. This technology offers high speed, affordable wireless access to “the last mile,”
While there are other technologies for wireless broadband access, Green Packet is convinced its product offers higher speed Internet access at an affordable price. Putting its money where its mouth is, it will soon network Klang Valley to its wireless Internet facilities.
The company will start to deploy its SONmetro infrastructure next month (Aug 2006) and launch the service possibly before year-end (2006). It will extend the network to other towns in a later phase.
At the same time, Green Packet is scheduled to set up a similar wireless Internet network in Bahrain, to be followed by Saudi Arabia and Dubai next year.

2nd 3G licence award in Malaysia March 2006
- TTdotCom Sdn Bhd and
- MiTV Corp Sdn Bhd
The loser was
- DiGi.Com Bhd
Digi is the third largest mobile operator in the country, which many people had expected to be the frontrunner for the spectrum. However, the decision of MCMC has caused a big surprise to the public. One of the possible reasons that Digi was not successfull is probably it does not offer much difference in terms of evolution of services and network as compared with existing 3G license holders (Maxis and TM).
Meanwhile, TTdotCom – a unit of Time dotCom Bhd in which Khazanah Nasional Bhd has a stake – gets a new lease of life and it plans to use the 3G spectrum to roll out broadband services.

Point to point directional antenna alignment
I was reported that the packet error is very low or zero, latency is high (a few hundred ms), but very low throughput. The SNR is about 10dB.
The most possible reason: distance too far (1km in this experiment with IEEE 802.11a). However, if this is the case, the packet error should be high. But, may be due to no or minimum connection.
In addition, given the fact that antenna beamwidth = 30 degree. The alignment should not be too critical. If I move closer I can get higher SNR or throughput, then that may be the problem is due to distant too long.
Here is a practical procedure that I am going to try.

WiFi Mesh Routers Design and Development Company in Malaysia
Chatting with their CTO, I found that we shared a common view on the positive prospect of WiFi mesh products, in particular in the provisioning of low cost broadband wireless solution.
First WiMAX certified products : Jan 2006
The WiMAX Forum revealed the first companies and products to complete certification and interoperability testing, including Aperto Networks' PacketMAX 5000 base station, Redline Communications' RedMAX AN-100U base station, SEQUANS Communications' SQN2010 SoC base station solution, and Wavesat's miniMAX customer premise equipment (CPE) solution.
About one year ago, the price was about US15,000 for one pair of BS+CPE. This is definitely too high for pervasive broadband wireless access. Hope fully with the more certified WiMAX products, the price will drop very fast. Meanwhile, I am also looking forward to the incorporation of WiMAX chip into notebooks which will make to CPE price much affordable for end users.

3G market expected to expand soon with more phone models
A survey conducted by MCMC in 2004 showed that 75% of subscribers spent less than RM100 per month. It is yet to see what kind of applications would really attract people to use the costly 3G services.

VDSL Network Sdn Bhd uses VDSL-FSO
VDSL would build its own network infrastructure using VDSL-FSO (very high bit rate digital subscriber line - free space optics) technology.
The advantage of this technology is that the time needed to set up the network is much faster as it operates based on, among other things, ABLFSO (air blown lambda fibre space optic) technology for its backbone infrastructure and even in some cases, wireless broadband for last mile connectivity to the consumer.

2nd round of 3G license bidding
i) DiGi Telecommunications Sdn Bhd,
ii) TT Dotcom Sdn Bhd, and
iii) MiTV Corporation Sdn Bhd
Mesh Network Market continues to grow
However, it is worth taking note that according to this new study from ABI Research, the increase will mostly come from deployments by alternative service providers and municipalities, rather than incumbent service providers. There will also be some "campus" style deployments in academic, corporate and resort environments, as well as temporary rollouts at conferences or fairs.
A major problem that would have to be worry by incumbent service providers is the Quality of Service (QoS). Can they guarantee the QoS in the presence of large number of existing WLAN users in the same vicinity?

TM Net introduces WiMAX in Q3 2006
It is glad to hear that another company in Malaysia, namely TM Net Sdn Bhd, is planning to introduce wireless broadband to area with little or no wireline service.
According to the news from the STAR.
TM Net is working closely with Intel and Alcatel. Meanwhile, to my knowledge, Intel is currently planning to conduct trial in Putrajaya and Cyberjaya area. The equipment used is so called pre-WiMAX equipment as there is no certified product in the market at the moment.
The certification process only begin mid of 2005, thus, it is expected that certified WiMAX product would only be widely available in 2006. At the moment, the price of pre-WiMAX transceiver + baseband unit is quite expensive, generally in the range of RM20K to RM40K per unit. However, it is still consider competative in some circumstances when compared with the cost of provisioning of ADSL services.
Refer to my research paper in IEEE VTC 2005 Fall
"Study on the issue of provisioning broadband services: The case of Malaysia" for more details.
However, its advantages as compared to WiFi mesh is still yet to be proven.

802.11n standard could be delayed until mid-2007
While hoping that existing two industry groups, WWiSE and TGn Sync, to harmonise and consolidate their proposal into a single proposal, rumous spread that "four major companies -- Broadcom, Intel, Atheros and Marvell, holding the lion's share of the Wi-Fi chipset market -- have formed a third camp with the aim of writing a whole new proposal.",
Industry observers have called this an offensive gambit aimed at Airgo Networks, an emerging chipmaker, to be forced it to a fundamental redesign.

Moral of the story:
poor people is alway difficult to play game with rich people who can alway show hand and this poor one just could not follow but give up
Broadband wireless access
The company has set up its optical backbone network, FTTC for condo, apartment in PJ and Penang. This is the right move for them. In fact Korean is using this model. The price for a 2Mbps uplink and downlink is only RM60. I think many people will want to go for it. Expecially, many people have fade up with the exisitng incumbant ISP.
It is also wise to look into tappinng the advantages of Wireless, where access to user to convenient, fast, and with mobility. Sound interesting in this combination of FTTC + Wireless. I suggest to them to use WiFi mesh which can provide coverage extension, a business model proposed for WiFi mesh.
