Shaw Go WiFi Status in Sault Ste Marie

Judging by the number of times the network “Shaw Open” is showing up during WiFi network scans in Sault Ste Marie, it appears the roll-out of the Shaw WiFi network is going extremely well.

In September, 2011 Shaw announced it was cancelling its plans to enter the cell network marketplace. In its stead, they proposed a WiFi network based on backhaul connectivity through the company’s broadband network. In the industry this is known as mobile data off-loading where data that would normally transit a cellular radio network uses a fibre optic or other broadband network instead.  Recent studies show that the amount of off-loaded traffic is approaching 50% in some jurisdictions. This frees up valuable, and expensive, radio spectrum for more real-time applications such as voice. It also means a user does not need to use expensive cellular (mobile) plan megabytes to view data intensive apps like videos.

Shaw branded their product as Shaw Go WiFi.

The Shaw Go WiFi consists of a large number of WiFi hotspots located throughout an area covered by a Shaw cable plant. Shaw provides the hotspots free to all manner of businesses, offices, public buildings, etc. in the target area.  The ultimate goal is provide as complete coverage of a locale as possible. The system is network agile which means it has the capability to hand-off active connections between hotspots as long as they have an overlapping electronic footprint.   Sources inform me that the maps of the WiFi locations have about a two week lag period from the installation date until they show up on the map.

To access the system, a user needs to be a Shaw customer, have a email address and be registered through the Shaw Go WiFi website.  You can have more than one device registered. A device is a cellphone, tablet, laptop or any other hardware that can connect to a WiFi network. The number of devices a user can register varies from as few as three to as many as 10 depending on the level of Shaw Internet service you subscribe to. The details are available in the FAQ area on the website.  

The use of the network is free but data usage is charged against the data cap in the plan the device is registered under.

As noted, as of this point in time, you can only use the system if you have a account. If you live outside the Shaw Internet coverage are, you are out of luck. There are a couple of work arounds. One is to establish Shaw account within the nearest coverage area. This can get a bit pricey as the cheapest Internet price is $50.00, after the $30 introductory offer, for 125 GB of data. Another option is have a friend or relation register your device on their plan and either depend on their kindness to cover your data usage or offer to reimburse them based on your data usage. In the above example the cost for data is 40 cents per gigabyte.

There is little doubt that Shaw Go WiFi is an example of the direction mobile networks are moving as data uses increase exponentially and radio spectrum becomes harder to acquire and more expensive.   While the technology works very well in urban areas, it is less advantageous to rural areas that do not have the underlying backhaul infrastructure or population density.

Tbaytel Data Hub Roaming

It appears the Tbaytel data hub roaming is back in business – kind of.  I gleaned the following from the Tbaytel Community Forum website. 
  • The Tbaytel policy of only selling Tbaytel data hubs to users for use in the Tbaytel coverage area still applies. This means that unless you have an address north of approximately 6th Line in Sault Ste. Marie they will not sell you a rocket hub. This is in compliance with the Rogers/Tbaytel operating agreement.
  •  As sold, the Tbaytel data hub is blocked from directly accessing the Rogers network through a Rogers’s site infrastructure. In other words it can only access a Tbaytel tower/site. However, Tbaytel will unblock the data hub so you can use it in roam mode while travelling. This is done by calling Customer Care at 807-623-4400. I would be prepared to cite the Tbaytel-Roy thread on the Community Forum as the source for the request. The unblocking setting will remain in force until you ask Tbaytel to change it back
  • Tbaytel does offer some good advice about being sure to ensure the US and International Data Block remains in place after the domestic roam feature is activated. Otherwise you may get very large roaming charges if operating near the US/Canada border both north and east of Sault Ste. Marie. In any case, one should confirm what network one is connected to periodically if you are using a data hub in an area that may incur roaming charges.

Data hubs acquired directly from Rogers can roam the Tbaytel network at will and without modification. When I had my Rogers data hub, it was blocked from roaming outside Canada so international roaming was not an issue.

Observations on the Canadian 700 MHz Auction


There has been considerable buzz about the possible entry of the US cellular company Verizon into the Canadian marketplace. This has been generated by hints that Verizon may purchase one or more of the new entrants formed as a result of the AWS (Advanced Wireless Service) frequency auction in 2008 – namely Mobilicity, Public and Wind. Verizon is able to do this because foreign ownership of cellular companies with less than 10% of market share is permitted. The AWS companies meet this criterion. 

Where this gets interesting is that although a purchaser likes Verizon may be huge when compared to the total Canadian market, by purchasing existing operators, Verizon will still be considered a new entrant. This means that Verizon will be able to take full advantage of the special considerations afforded new entrants, in particular spectrum allocation, tower sharing, and roaming agreements.

Needless to say the incumbents are not happy with this state of affairs and have been crowing loud and long about the unfairness of it all with all three CEO’s issuing statements and threats within the last few days about how the market will suffer if Verizon is allowed to proceed and enter Canada.

Vidéotron has now joined the chorus for reasons I cannot fathom because they are considered a new entrant as well as a regional carrier and are fully protected by some of the auction rules.
Auction Blocks

The main driver for this outburst of high dudgeon is the upcoming 700 MHz auction. Some background information may help understand the situation.

When Canada (and the US) converted from analogue to digital television a few years ago, it freed up a considerable amount of radio spectrum in the 700 MHz band and it became available for use by cellular services.

In Canada, the available frequency spread was divided into blocks as shown in this chart. The channel numbers at the top of the chart refer to the old TV channel numbers. Channel 51 is still an operational channel and it has the potential to interfere with the lower Block A frequencies. This makes Block A spectrum a little less value. For auction purposes, four blocks are considered “prime” and come with some restrictions as will be explained later.  These are Blocks B, C, C1 and C2.
 Canadian plan for the bands 698-756 MHz and 777-787 MHz

 This is the key information in an easier to read format.

The following frequency blocks will be available for the 700 MHz auction:
698-704 MHz/728-734 MHz
6+6 MHz
704-710 MHz/734-740 MHz
6+6 MHz
710-716 MHz/740-746 MHz
6+6 MHz
716-722 MHz
6 MHz
722-728 MHz
6 MHz
777-782 MHz/746-751 MHz
5+5 MHz
782-787 MHz/751-756 MHz
5+5 MHz

Paired means that there are two blocks separated by sufficient bandwidth to allow one block for download and one block for upload.

Unpaired means the block is standalone and is most valuable for one way transmission.

Coverage Areas
The auction rules set license boundaries for coverage areas.  As explained on the Industry Canada/Spectrum Branch website, these areas, called tiers, are based on Statistics Canada’s Census Divisions and Subdivisions. Four tier sizes have been established to accommodate various wireless services, applications and frequency bands.
·         Tier 1 is a single national service area;
·         Tier 2 consists of 14 large service areas;
·         Tier 3 consists of 59 smaller regional service areas; and
·         Tier 4 comprises 172 localized service areas.

For the upcoming auctions, Tier 2 boundaries will apply.  Northern Ontario is considered one of the 14 large service areas.

There are a total of 7 frequency blocks available for each Tier 2 area. However, the incumbent carriers may only purchase one prime block per area while new entrants can purchase two prime blocks per area. For auction purchases, regional carriers such as Tbaytel, Vidéotron, and EastLink are considered new entrants and may bid on two prime blocks.  This means in theory, one incumbent vendor will be excluded from prime blocks in each Tier 2 area.  

There is nothing in the rules which prevent one or more of the incumbents developing a frequency or network sharing agreements as long as it is made public before the start of the auction. Rogers and Vidéotron have such an agreement now but they have not formally stated it will extend to the auction. None of the incumbents have joint LTE operating agreements, or at least any visible in the public domain.

Where it gets interesting is if we look at how these prime blocks are used in the US marketplace. AT&T uses the B and C blocks while Verizon uses C1 and C2 blocks. This usage becomes critical when Canadian carriers workout roaming deals with US carriers; the handsets need to match the frequencies. There is also the issue of roaming default hierarchy. While both AT&T and Verizon have LTE networks, it is not always available and connections default to older, and often slower, standards. AT&T phones default LTE to HSPA to GSM which is the standard used by Rogers and most of the Canadian new entrants. Verizon phones tend to default downward to their CDMA core network which is the standard used by Bell, Telus and Public.

Most smartphones sold in Canada default to GSM, even the ones sold by Bell. This is why Bell smartphones have limited network access between Sault Ste. Marie and Thunder Bay. While Verizon sells smartphones that can default to CDMA as well as HSPA, I am not aware of any that are sold in Canada.  My Samsung Galaxy SII defaults to AT&T or T-Mobile when in the US. Apple iPhones react likewise.

The bottom line is many observers feel that if Verizon follows through on the auction, they will go after the CI and C2 blocks which they are able to do under the two block rule in order to maintain compatibility with their US operations.

Tier 2 Areas

Northern Ontario Tier 2-09

 Technology Roll Out

The auction also has rules concerning roll out of advanced technology in rural areas. Incumbents and new entrants who either purchase or have access to two paired blocks (not necessarily prime blocks) are required to provide 700 MHz coverage within 5 or 7 years to cover 90% and 97% respectively of the area their HSPA coverage provide in 2012. 

In effect, this means the new entrants have minuscule urban areas to cover while the incumbents have to cover about 75% of the country. The regional carriers are somewhere in between.

The only pressure on the new incumbents is that they must provide coverage within 10 years to a range of 20% to 50% depending on the geographical area. For Northern Ontario it is 50%.  Unfortunately, this can be achieved without providing any new technology or 700 MHz coverage in rural areas and by simply upgrading urban networks.

That is not to say they will not; just that they do not have to.  However, using the 700 MHz band blocks on existing or co-shared towers in rural area would allow for greater coverage while repurposing the most expensive part of the necessary infrastructure, the towers and ancillary structures. On the flip side of the coin, lower frequencies like 700 MHz can handle les bandwidth than the higher frequencies so congestion may quickly become a problem.  In summary, higher frequencies equal more bandwidth but less coverage while lower frequencies equal more coverage but less bandwidth.

The auctions rules also state that all network operate must allow network roaming and share tower by all service providers. This means a new entrant like Verizon can advertise and offer full national coverage on one of the incumbent networks without spending any capital for network infrastructure. They will have to pay the infrastructure owners reasonable rates in accordance with CRTC and Industry Canada directives. There are some hardware challenges and technology issues that need to be resolved but these are not insurmountable.
