Bus error: Jake Billo’s weblog

From a HowardForums post, I’ve found out that the Canadian Internet Policy and Public Interest Clinic is seeking comments from people affected by Bell or Rogers’ throttling. This refers to Bell’s global limitation of about 30K/s for BitTorrent, and Rogers areas affected by Ellacoya/Sandvine boxes.

I’ve written Robert Hester an email about my own experiences on TekSavvy, which I’ll repost below. If you’ve been affected by this nonsense, it might be worth your while to write in before a decision is made in September.

Hi Robert,

I read a post from a CIPPIC alias on HowardForums (http://howardforums.com/showthread.php?t=1406593) and figured I’d contribute my experiences with Bell’s internet throttling.

I’m a Computer Science student in Waterloo, Ontario, and currently subscribe to TekSavvy - a Bell DSL reseller. I chose them because I consider Bell Sympatico service to be substandard in the market: Bell’s technical support is lacking at best, they limit bandwidth usage to 60GB per month, and they don’t offer additional features such as static IP addresses.

Bell has applied throttling to their wholesale customers including TekSavvy, specifically for P2P protocols such as BitTorrent. When this network management is active - which I find tends to be more than twelve hours out of every day - my BitTorrent download speeds are limited to 30-50KB/s. This is a far cry from the 5Mbit (~500KB/s) service that I pay for.

What really disappoints me is that an independent reseller has to suffer because Bell unilaterally decides to squash competition. Unfiltered P2P and unlimited bandwidth usage are key competitive features that I’m willing to pay for. When a third party like Bell decides that they can’t compete and uses technical restrictions to bring other services down to the same level of reduced functionality, I’d go as far to say it’s an unfair trade practice. In my opinion: if this practice is not currently illegal, it should be.

I have no objection to reasonable network management, but reducing download speeds to 10% of their potential based on a transmission protocol is far from reasonable.

Thanks for your time and consideration on this important issue. Please feel free to contact me at the email address or phone number below if you require anything else.

From HowardForums: Bell is launching two new personal data plans similar to Telus’ Email and Web 30.

• Unlimited Personal Email & Internet BlackBerry 30
• Unlimited Personal Email & Internet Windows Mobile 30

On the BlackBerry, this package offers unlimited data since all traffic flows through the BIS browsing transport - the only thing restricted is tethering the device to a computer for Internet access, which is charged at $15/MB. US roaming is $8/MB, both figures which seem to fall in with the ridiculous state of Canadian wireless data charges.

While I personally don’t use Bell for wireless - and would definitely go with Telus over Bell if choosing between CDMA carriers - the company has a large number of BlackBerry devices provisioned. It’s a competitive move before the Rogers iPhone and BlackBerry Bold launch, and if you don’t need BES access, this might be a worthwhile plan to investigate.

I was catching up on some of my feeds this afternoon and noted a comment I’d posted on Phil’s blog about what “unlocking” a cell phone really meant. Apart from my day job working for a wireless device manufacturer, where people swap SIM cards and batteries between devices in about 20 seconds, and talk about IMSI, MSISDN and ICCIDs like it’s nobody’s business, it’s often not easy to understand why wireless providers do the things they do. I’ve talked to people who didn’t understand why they couldn’t use their Bell phone on Rogers; or why Rogers made them switch their phone or plan.

Here’s an explanation of some of those issues and a brief background of the state of wireless in Canada.

Currently, in Canada, there are four major providers, several regional or localized carriers, and a number of virtual mobile network operators that piggyback on the major providers’ networks. There are also three different wireless technologies actively used for service. The major providers are:

• Bell Mobility, the wireless arm of Bell Canada. Bell’s prepaid division is called Solo Mobile
• Rogers Wireless, part of the ubiquitous Rogers group of companies
• Telus, who operate standard wireless services and push-to-talk (CHIRP) technology under the Mike brand
• Fido, formerly Microcell Telecommunications, who are owned by Rogers

Of these providers, Bell and Telus use a technology called CDMA. The Wikipedia page on the technology deals with some highly mathematical concepts such as vector orthogonality, but effectively for end users, indicates the type of technology used in phones and wireless towers. CDMA devices are generally only usable on one network - the provider who issued the device.

The alternative technology to CDMA is GSM. Rogers and Fido use GSM, which operates on two radio frequencies in North America: 1900MHz and 850MHz. The 850MHz tower signals generally have better coverage indoors. The distinctive feature of GSM is that all devices have a SIM card, which contains operator information, the subscriber phone number, and address book information.

The final technology, iDEN is used by Telus for the Mike PCS brand. iDEN devices support “push-to-talk” technology and also contain SIM cards. These SIM cards may or may not be compatible with GSM phones, though.

So why can’t I use my Bell phone on Rogers?
Since Bell uses CDMA technology and Rogers uses GSM, phones are physically not compatible with the other provider’s network. The radio transmitter internal to the phone uses different frequencies and CDMA phones don’t read SIM cards.

So why can’t I use my Telus phone on Bell?
Telus and Bell won’t activate a phone not provided by them on their own network. While the technology is the same, phones are typically preconfigured with individual carrier settings that aren’t necessarily easy to change on CDMA devices.

Why did Rogers make me change my phone?
Since approximately May this year, Rogers turned off its older network, which used analog towers and an older technology for transmitting wireless signals. Customers were required to upgrade to a GSM capable phone and in doing so, the coverage area should be improved.
