Opp mws

[Muxlow]

Im wondering about the OPP and their mobile work stations
Iv noticed on quite a few new opp cars they have 2 or 3 antennas on the roof now.
Well iv always saw the one now they have 2 extra.
How do they get the "internet?" or the data to their toughbooks?
Is it a hidden wifi kinda deal, or does the signals come from the fleetnet towers or hows that all work out?

I think TPS uses Rogers for their data stuff. Since OPP is Fleetnet its probably on Bell's 3G or something like that. That would be my guess.

I know that they are either on Bell or Telus (I was told once, but I can't remember).... they use Panasonic Toughbook's in the cars. Not sure how many of the cruisers have them. I know that the media guys (Dave Woodford) use them to do all the press releases in their cars...so news gets out a lot faster.

 

[Muxlow]

Soo is it just like the bell wireless internet card you can get? Work by usb. Is it something like that? Or does the signal come stright from a fleetnet tower

 

[yorkphotog]

It isn't a USB card.. AFAIK, it's built into their Toughbooks (some Dell, Lenovo, and Panasonic laptops come with integrated cellular internet). Next time I'm in a cruiser, I'll find out whether they are on Telus or Bell.

 

[mikewazowski]

OPP are on Bell Mobility Cellular for their internet access.

 

[Muxlow]

What type of antenna do they use for that?

 

[SCPD]

one of 2 things a 3 g card or its built in the laptop you dont need a aerial

 

[yorkphotog]

It's built in... but I'm still not sure why so many of the cruisers have multiple antennas....

Also, FYI.... the Bell portable internet runs on the same platform as the Rogers portable internet (it was actually a joint mission). Neither Rogers or Bell internet will work if you are mobile -- you must be well within range of a tower and cannot be moving. Telus' mobile internet, on the other hand, will hand off your signal to towers as you go.

You need to take a closer look at what your wrote.

You're comparing Bell and Rogers PORTABLE internet to Telus' MOBILE internet.

Apples and Oranges.

A more valid comparison would have been to compare Bell and Rogers MOBILE internet to Telus' MOBILE internet.

In fact, Bell and Telus both use the same MOBILE internet technology.

All 3 Company's MOBILE technologies will easily handle handoffs between towers.

I've driven from Huntsville to Collingwood while maintaining a internet connection using Rogers' MOBILE internet. I handed between towers the whole journey and actually handed from HSPA to EDGE to GPRS while not dropping my VPN connection.

The OPP would be using Bell's MOBILE internet and chances are, the laptops have an external antenna port.

We had iTronix GoBooks with builtin Aircards but they provided an external antenna connection that could be connected to a small whip antenna on the side of the display or an external antenna.

Here's a link to the newer version of what we had:

Rugged Notebook Computer - The General Dynamics Itronix GoBook XR-1 MIL810F laptop computer with Dyn

Mobile, portable.......oops.

I'm referring solely to "portable" internet.
Rogers Communications - Wireless, Digital Cable TV, Hi-Speed Internet, Home Phone
Internet services- bell.ca
Connect Plans | TELUS

 

[mikewazowski]

The Rogers and Bell plans you highlighted are PORTABLE internet. The Telus plan you highlighted is MOBILE internet.

Telus' Internet is MOBILE since that's all they can offer in this area.

Bell and Rogers can offer both MOBILE and PORTABLE internet.

The OPP would use Bell's mobile internet while TPS uses Rogers mobile internet. They're both using the cellular network.

You can think of portable internet as home internet that you can take with you where ever you go. It operates around 2.4Ghz and offers speeds faster then mobile internet.

While I was working in Windsor, I took along a portable internet modem to use in my hotel room since the hotel wanted $10/day for wireless.

A lot of people with cottages use the service as well.

If you want mobile internet, then you're going to use a cellular based service such as HSPA or 1X.

Would one antenna be for RX and the other 2 for TX? Thats how London police have theirs set up.. 2 for the same thing and one for the other

I was just wondering what type of antenna the ones opp use are called

And i have a bell mobile net usb thing. Works all over when im driving. Never lost a signal yet

 

[sirsmiley]

the cars will most likely have a a pair of antennas..one for rx one for tx, and will have a cell modem (not a simple usb device) from bell business division that will use a cell signal to tunnel in with a secure connection to orillia via the internet.

Without knowing what radios they have in their vehicles, it's all guessing.

Could be a GPS, cellular modem and radio antennas.

Could be a GPS, 800Mhz radio and VHF radio antennas.

Most cars these days have AVL so they'd need a GPS antenna.

If they've got an 800Mhz radio, then they've probably got an 800Mhz antenna.

Some 800Mhz mobile systems also have a VHF radio "drawer" in the trunk which is accessed through the same control head. This gives them access to Provincial Common and other EMO frequencies. This would probably require another antenna.

Then there's the antenna needed for any mws system installed (if needed).

Hard to tell without knowing anybody from the radio shop.

Unless they're running a full duplex radio system (no police agencies are), then there's no need for separate rx and tx antennas.

Okay..

WiMAX (2.5GHz) Inukshuk :
- Rogers Portable Internet
- Bell Sympatico High Speed Unplugged
Yesterday, LOOK Communications has agreed to sell its spectrum from 2.5 to 2.6GHz for Inukshuk. Consumer modems cannot roam. That is, transfer seamlessly from one tower to the next. Towers are also spaced much further apart than cellular so coverage is severely limited although the coverage maps are fairly accurate given my experience with it. There are supposed public-safety version that does roam seamlessly, but I'm not sure.

Primus was doing a pilot of a 3.5GHz WiMAX project in Hamilton but I haven't heard anything else about it.

Cellular:
- Rogers HSDPA (3.5G)
- Bell and Telus EVDO Rev. A (3G)
- Bell and Telus HSPA/LTE (4G, urban cities Q4 2009, national ETA 2010)
Rogers touts their 7.1mbps HSDPA network, but they have not rolled it out nationally yet. HSDPA works in most of the populated areas but you're back to EDGE in the rural areas.

 

[h4waii]

For pete's sake. It's running over the cellular network. Bell runs on CDMA with EVDO REV.A and soon to be LTE, Rogers runs it on UMTS over WCDMA and "soon" to be HSPA.

The above poster has it right. they are not using the Inukshuk service. That is very limited to a stationary location. They are not using an antenna for Rx and an antenna for Tx. Infact, I doubt these antenna's are actually connected to the laptops unless they are in a zone with crappy cell coverage.

 

[mikewazowski]

Rogers runs it on UMTS over WCDMA and "soon" to be HSPA.

Actually HSPA (HSDPA/HSUPA) is the data bearing portion of UMTS and is what's running now.

Much like EDGE is the data bearing portion of GSM.

But bottom line, you're correct. The MWS's are running on one form of cellular network or another.

OPP has the 2 pucks (antennas) on the roof for the MWS. One transmits, on receives. The modem is in the trunk connected to the pucks with cord. A cord from the modem then goes up and plugs into the MWS. It runs at 100mbs. The MWS encrypts the signal outgoing and receives the incoming encrypted signal.

Cars with 3 pucks...are in fact older cars, where the system has been upgraded and the centre puck is in fact dead, but just easier to leave the puck there than try a patch job on an operational cruiser.
