TELUS’ networks
The Company has a coast-to-coast fibre optic network, which interconnects cities
between Halifax and Vancouver and extends into the U.S. via points of presence in
Albany, Ashburn, Palo Alto, Boston, Buffalo, Chicago, Detroit, New York and Seattle.
This network is fully integrated with TELUS’ extensive metropolitan networks in Alberta
and B.C. and connects into networks constructed in Montréal, Ottawa, Toronto and other
cities. As at December 31, 2007, the total amount of network fibre reached more than
18,000 kilometres.
TELUS wireline networks
TELUS’ wireline network includes the Alberta and B.C. portion of the transcontinental
high-density fibre optic transmission system used by the various incumbent local
exchange carriers (“ILECs”) across Canada. As part of the national strategy, TELUS
also built its own national inter-city fibre optic backbone network that interconnects the
network in Alberta and B.C. with major centres in Ontario and Québec. This fibre optic
network is supplemented by new local fibre optic networks in 54 competitive local
exchange carrier (“CLEC”) exchanges or metropolitan areas. TELUS’ network
interconnects with the networks of Verizon Communications Inc. (“Verizon”) and other
carriers in the U.S. for the exchange of U.S. and international traffic.
TELUS wireless networks
TELUS is one of three national Canadian facilities-based wireless service providers, and
offers wireless voice and data services to consumers and businesses nationally on two
networks. As a result of acquisitions and purchases completed in previous years,
TELUS holds a significant mobile spectrum position of up to 45 MHz PCS and cellular
spectrum and as much as 55 MHz in many areas with the inclusion of its iDEN network
spectrum. The federal government will make available additional wireless spectrum
through an auction in mid-2008 and further auctions are anticipated for spectrum in the
700 MHz and 2.5 and 2.6 GHz bands. See “Upcoming spectrum auction”.
PCS/cellular networks
TELUS owns and operates a national digital PCS network and analogue/digital cellular
facilities in Alberta, B.C., and eastern Québec, with 40 to 45 MHz of PCS spectrum
throughout all major population regions of Canada. Its national PCS wireless network
utilizes 1X, CDMA (code division multiple access), and EVDO and EVDO Rev A digital
technology.
TELUS expanded its network coverage through roaming/resale agreements entered into
in 1999 (“the Roaming/Resale Agreements”), principally with Bell Canada and certain of
its affiliates. These agreements expanded TELUS’ digital PCS coverage areas outside
of major urban markets in Ontario, Québec and Atlantic Canada and were subsequently
amended to include 1X and the EVDO high-speed network. At the end of 2007, TELUS’
national digital networks, combined with coverage provided by the Roaming/Resale
Agreements, reached approximately 31.6 million Canadians.
In 2004, TELUS and Verizon Wireless expanded their Canada and U.S. roaming
arrangements under a consolidated long-term roaming agreement to improve each
