HSPA+ Multiflow

If you were to read this page, you will find out that Nokia Siemens is gearing towards a new technology where it will allow a mobile device to be connected to two cell tower simultaneously. In doing so, it will cut down the potential drop calls especially when a mobile device is located close to the edge of a cell tower.

Personally, I welcome this technology with open arms. I think it is not too late to introduce such technology because we need to be able to access to internet at broadband speed especially with the introduction of LTE in the near future.

At this moment in time, O2 UK has deployed 3G 900mhz and other mobile networks will have to follow them. With LTE, mobile network providers who run on the O2 UK network will benefit greatly as it has extended the coverage range of the cell network.

I will be waiting for such technology to be deployed by OEMs. At this moment, we have quadband GSM + Pentaband UTMS + LTE with A-GPS + GLONASS. I will be most delighted to see more technologies to be deployed soon.

Kudos to Nokia Siemens!

System Management for Internet Service Providers

If you are a keen internet user, have you ever experienced your internet service being "slowed down" for no apparent reason? Well, if you do, welcome to the world of "System Management" as what O2 will tell its customers. If you refer to this link, it will show you what O2 will do when a user is using p2p or merely downloading or even trying to watch a rented movie via streaming. Let's face it, all Internet Service Providers or ISP will throttles the speed of your broadband irrespective of whether you are using an ADSL 2+ or via a fibre optics modem like Virgin Broadband.

ISPs are telling customers that they need to do so to ensure that all customers will be able to enjoy a respectable broadband speed. Well, this is true to an extent. Imagine if there is and exchange for 10000 connections and amonth those 10000 household, only 10 percent of them use more than 100GB of download/streaming per month. The rest would only download occassionally. Due to the 10 percent of household who are indulged in heavy downloading, the rest of the household had to suffer a slowdown on their broadband because the exchange could not provide sufficient bandwidth to the rest of the household as the 10 percent had occupied most of the bandwidth.

The solution is simple. ISPs will issue a statement stating that they will manage the traffic of each household who use their internet service to ensure that there will be sufficient bandwidth for all users. Even TalkTalk Broadband is following other ISPs to do so. Bear in mind that TalkTalk received the most complaints regarding their broadband and phone  services recently so you might want to think again when subscribing to TalkTalk Broadband. In doing so, ISPs will not need to improve on their bandwidth in such a short span of time. They will have sufficient time to improve on their infrastructure.

Well, what about consumers then? Does consumers have a choice when signing up to a broadband service? I would always recommend people to have a look on an ISP's website and forums as to their reliability of service and also their customer services. Personally, I was on Virgin Broadband which I was paying £21 a month for 10mbps download and 1mbps upload where there is no limit in how much I can download. Virgin Broadband is fairly alright with their customer services and on their reliability score. Make sure that your house is within their fibre optics coverage. Otherwise, you will have to pay around £35 for a landline and an ADSL broadband which is just too much considering that O2's Home Broadband is only £20 a month for the similar package but without free of peak minutes to UK landlines excluding premium numbers.

In a nutshell, we as consumers could not avoid ISPs in managing their traffic but always choose a broadband service provder carefully. Don't just sign up to one without doing a research.

Good luck!

Compaq W200 Multiport

If you are one of those people who are finding difficulty in getting the Compaq W200 Multiport to work, please have a look at my explanation.


I am one of those nerds who bought a Compaq Presario 2800 notebook without Wireless LAN. All I have been doing is to use LAN and wireless through usb. I am kinda wondering whether it is possible for me to install a Wireless LAN card on the Presario 2800 without using an additional usb port. Well, I've made it...Just.


I have purchased a Compaq W200 Multiport for my Presario 2800 and guess what? Installation of the wireless LAN card onto the notebook was the easy part. What is difficult is the ability to get it to work!!! Yes, it is difficult. I have managed to install the software which was provided when I bought the Wireless Lan Card and it worked fine. I believe the software version was 1.00C. After installing the software, I have a problem.


I can't seem to log on to any of the wireless Access Points!!! How strange!!! That prompts me to google and have a look at how to solve this problem. I was then told that I need to upgrade the software to 1.00H. Alright, I did it and guess what? I had a BSOD.


It is not funny though. I get BSOD whenever the W200 fires up. That is not good because I can't make use of the piece of hardware which I have just bought! So much for preserving a 7 years old notebook!!! Oh well, I went back to google and look at the possible ways to overcome BSOD.


After looking for ages, I have come to a conclusion - I have to stick to software version 1.00C if I want to use the W200. The problem with the 1.00C software is that it does not support WPA!!! Oh my! That is bad...


In the end, I have to abandon the W200 wireless lan card project and stick to a usb 802.11g wireless lan adapter. How sad...


Update: 28/03/2009 - I have not yet given up on the W200 Multiport yet. Right now, I am actually trying to use the SP30513 driver. I really hope that it will solve the BSOD problem which I have experienced for so long. I really don't want to use usb wireless adaptor anymore...
