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).

KL, A Wireless City

According to Bernama, under an MOU signed with MCMC, Packet One Networks (P1) will be setting up many WiFi access points covering Kuala Lumpur and Klang Valley with the aim of increasing broadband coverage to 90 percent of the population by 2010.


Meanwhile, according to a newspaper report recently, P1 will be providing wireless access service by using a combination of WiMax and WiFi technologies.
P1, which is one of the 4 Wimax license holders. The other WiMax license holders are Bizsurf (M) Sdn Bhd, Asiaspace Dotcom Sdn Bhd and Redtone-CNX Broadband Sdn Bhd. Bizsurf, Packet One Networks (M) Sdn Bhd (formerly known as MIB Comm Sdn Bhd) and Asiaspace Dotcom will cover Peninsular Malaysia while Redtone-CNX Broadband will serve Sabah and Sarawak. According to the original plan, these companies are supposed to provide WiMax service by end of 2007.

However, it is a joke to realise at the later stage that there is no certified WiMax mobile equipment at 2.3GHz (probably refer to the reasonable cost equipment).
Now, instead of providing WiMax broadband wireless access service, these companies are now using WiMax as backbone instead. This has defeat the original purpose of MCMC to award WiMax licences at 2.3GHz, i.e., for mobile broadband wireless access.

In this WirelessKL project, P1 is in fact using WiMax as the backhaul solution.

Satellite Communications in Malaysia

Measat Satellite Systems Sdn Bhd announced that Measat1R, which has been renamed Measat3a, will be launched in the third quarter of 2008.

MEASAT (Malaysia East Asia Satellite) is the name of a line of Malaysian communications satellites owned and operated by MEASAT Satellite Systems Sdn. Bhd.

As of 2006, the MEASAT satellite network consists of three geostationary satellites. MEASAT-1 and MEASAT-2 were launched in 1996 and MEASAT-3 in 2006.
The MEASAT-1 and 2 satellites were designed to provide 12 years of both direct-to-user television service in Malaysia and general communications services in the region from Malaysia to the Philippines and from Beijing to Indonesia. With the launch of MEASAT-3, the coverage extends even further to an area encompassing 70% of the worlds population.

According to the news, Measat3a has been designed to be co-located with Measat3 at the 91.5 degree E orbital hot slot. The satellite will provide 12 high-powered C-band transponders providing coverage across a region bounded by Africa and Eastern Europe in the West, through to Japan and Australia in the East, and 12 high-powered KuBand transponders for direct-to-home customers in Malaysia and Indonesia. The satellite is constructed by Orbital Sciences Inc and is planned to be launched on a LandLaunch Zenith3SL launch vehicle.
