Thumbs Down for Pink LG Neon TE365
Whenever I see a pink gadget, like a cellphone for instance, I usually am intrigued by it and would so love to own it and play with it.
Unfortunately, there’s this one pink phone that I do not like at all. It is cute, yes, but unfortunately, this phone is of very poor quality. 
This phone is the LG Neon TE365 phone. It comes in other colours, too. I just wanted to specifically mention this phone because it comes in pink, which is what I am easily attracted to.
I have talked with a lot of people who own this phone and the most common problem with it is that the phone keeps freezing a lot. It could be you’re making a call, typing a text message, browsing the internet, or even not doing anything at all and the phone would just freeze on you. Some people would say that they just put the phone in their pocket and then when they took it out, toink, it’s frozen.
Another problem is that this phone would just randomly turn off on its own. Same situation, whether you’re doing something or not doing anything at all.
When these happen, the solution would be is to bring the phone in for repair back to the manufacturer. But actually, even if the phone is “repaired” already, it still tends to have the same problems.
Third common problem? The keyboard gets stuck or doesn’t slide properly.
I’m wondering why they still even sell these phones. By the way, other LG phone models may tend to have the same set of problems, too, so be cautious in your decision to purchase any LG phone.
I’m sorry, LG, you know that’s the reality.
iPhone Mail Settings
If you have an iPhone, you can easily add your email account if you’re using one of the default emails under the Mail, Contacts, Calendars setting, namely GMail, Yahoo Mail, and AOL. And I guess MobileMe, though I wouldn’t say it’s a common mail account used.
For Canadians, a lot of people have an email account from their Internet Service Provider, like Rogers, Bell or Telus for example among others.
It should be pretty straightforward to setup your email actually since you can just check the settings on your computer if you’re using a mail client such as Microsoft Outlook for example. If the iPhone is looking for the incoming mail server, just check it on your mail client’s settings. If the iPhone is looking for the outgoing mail server, check it in your settings again. But I guess some people are just not very technically savvy that they have no idea what and where to find that, and I understand that.
Now, what would the world do without technical support people, right? LOL.
Anyway, here’s a compilation of the required mail settings of the most common email providers in Canada.

Obviously, when you have a username, you should also put your password in the Password section. Just leave the other settings I haven’t mentioned here as default.
Take note that the Outgoing (SMTP) Server will only work over a WiFi connection. If you’re sending out email through your wireless mobile phone network provider, you would need to add their SMTP server, e.g. Rogers Wireless uses smtp.rogerswirelessdata.com [port 25]. Check with your network provider for this setting.
Remember, if you’re having trouble sending email, try turning off your WiFi, then it should usually work fine, as long as you have your network provider’s SMTP server configured.
Additionally, if you have a work email, that usually means you might have to add your email by going into Settings > Mail, Contacts, Calendars > Add Account > Microsoft Exchange. Take note, only one Exchange ActiveSync account can be configured on the iPhone. Contact your company’s Mail Administrator for this.

iPhone 3GS vs iPhone 3G
As far as I can recall, a couple of people have asked me what’s the difference between the iPhone 3G and iPhone 3GS. My answer? The iPhone 3GS is faster (S is for speed!). And it also has the Compass feature. Okay, not such a good answer, eh? I should’ve expected this question to come up at any time and should’ve taken note of the things that make the 3GS better than the 3G.
According to Apple, iPhone 3GS is “the fastest, most powerful iPhone yet. Now with built-in video camera, Voice Control, longer battery life, and more.”
The 3GS camera is 3 megapixels, has autofocus, and video recording. On the other hand, the 3G has only 2 megapixels. Other new features of the 3GS include improved performance (faster!), voice control, and compass. Five other features that come with the latest version software (3.0 and later) include Cut, Copy & Paste, Messages, Spotlight Search, Landscape Keyboard, and Voice Memos.
Battery life for the 3GS is also better with the following differences: Talk time is up to 12 hours on 2G (compared to 10 hours on the 3G), WiFi internet use up to 9 hours (compared to 6 hours on 3G), audio playback is up to 30 hours (compared to 24 hours on 3G), and video playback up to 10 hours (compared to 7 hours on 3G).
Those are basically the differences between the two. Oh and just a note, by looking at the two, there’s no physical difference really. To distinguish between the two, you can take a look at the back. The iPhone label at the back for the 3G is in black, while the 3GS is in chrome just like the Apple logo.

The GSM Network
GSM (Global System for Mobile communications: originally from Groupe Spécial Mobile) is the most popular standard for mobile phones in the world. Its promoter, the GSM Association, estimates that 80% of the global mobile market uses the standard. GSM is used by over 3 billion people across more than 212 countries and territories. Its ubiquity makes international roaming very common between mobile phone operators, enabling subscribers to use their phones in many parts of the world. GSM differs from its predecessors in that both signaling and speech channels are digital, and thus is considered a second generation (2G) mobile phone system. This has also meant that data communication was easy to build into the system. [Wikipedia]
Registering a handset in the GSM network works this way– The handset listens for a SID (System Identity) being broadcasted by the closest BTS (Base Transceiver Station) a.k.a. the tower. Once it receives a SID, the handset transmits its IMEI (International Mobile Equipment Identity) number and MIN (Mobile Identity Number). It goes through the BSC (Base Station Controller) which determines whether the transmission is voice or data. The BTS and BSC combined is called the BTS (Base Station Subsystem). (The TRAU (Transcoding Rate Adaption Unit) which isn’t usually identified, also exists to provide repeater functionality to maintain signal strength.)
It then goes to the MSC (Mobile Switching Centre) which authenticates, validates, and locates the subscriber. It checks the HLR (Home Location Register) which is the database of the customer’s SIM services (i.e. SMS, Voicemail, Long distance, Call display, etc.). Once it confirms the subscriber services, it goes back to the handset the same way, but all these happen so fast that it becomes seamless to the subscriber.
Another component in the network is the GMSC (Gateway Mobile Switching Centre) which routes calls targeted to another carrier’s wireless network or the PSTN (Public Switch Telephone Network). There is also a VLR (Visitor Location Register) which is used for load balancing as it stores subsets of information from the HLR when the subscriber is not in his home area.
When roaming, there also is the EIR (Equipment Identity Register) which is a database of all blacklisted equipment (though this one is rarely used these days already). There is also the AuC (Authentication Centre) which stores the private key for SIM authentication. Both of these are connected to the MSC.
For data services, a.k.a. GPRS (General Packet Radio Service), the SGSN (Serving GPRS Support Node) acts as the MSC. It then goes to the GGSN (Gateway GPRS Support Node), then depending on the APN (Access Point Name), it will go out to the Internet in varied ways.
There are three APNs commonly used. Goam.com, which is used for plain text browsing, accesses the Internet via a WAP Gateway. Internet.com, which is used for HTML browsing, accesses the Internet via a NAT Server. Thirdly, Media.com, which is used for multimedia messaging, accesses the Internet through a WAP Gateway, then a MMSC (Multimedia Service Centre) or SMTP server (for email).
These are all the network components in the GSM network which are nice to know especially if you work in the telecommunications industry.

SFN and OFDM
July 28th, 2008 questions and answers in my Advanced RF/Wireless Techniques class.
1. What is SFN?
SFN, or Single Frequency Network, is a broadcast network where several transmitters simultaneously send the same signal over the same frequency channel.
2. Why does OFDM enable SFN technique?
OFDM, or Orthogonal Frequency Division Multiplexing, which is used in wideband digital broadcasting, enables SFN technique in order to have efficient utilization of the radio spectrum, allowing a higher number of radio and TV programs in comparison to traditional multi-frequency network (MFN) transmission. An SFN may also increase the coverage area and decrease the outage probability in comparison to an MFN, since the total received signal strength may increase to positions midway between the transmitters.
SFN considerably improves the utilization of frequency bands and channels as well as energy balance of digital transmitters. The signal coverage of a certain area can be provided by a number of transmitters, transmitting the multiplex of digital television or radio signals in the identical frequency channel. Their partial signal contributions in the reception point not only do not interfere, under certain circumstances then even improve the reception.
3. What are the benefits of broadcasting using SFN?
The benefits of broadcasting using SFN are:
- Improvement in the utilization of frequency bands and channels in the available spectrum,
- Improved coverage area, and
- Decreased outage probability.
