EXHIBIT 99.2 NEWS RELEASE Attention business/financial editors and telecommunication reporters: Coventry Connections selects Sprint Canada and Mobile Knowledge to provide
IP-based telecommunication services and mobile systems solutions for
state-of-the-art command and dispatch centre TORONTO, ON  August 11, 2004 Coventry Connections Inc., a holding company
that provides services for seven taxi fleets in southern Ontario, has selected
Sprint Canada and Mobile Knowledge Corp. to implement an inter-city
computerized taxi command and control system, consolidating dispatch centres
for a number of taxi fleets into one centralized call centre. This is the
largest centralized taxi operations system implemented in Canada, and the first
to operate across multiple cities. Sprint Canada will provide toll free and frame relay data network services and
Mobile Knowledge will provide its advanced taxi solution, Cabmate, to power
the centralized call centre. The state-of-the-art centre will enable Coventry
Connections to expand easily and efficiently into new geographic markets, with
lower operating costs than previously possible with traditional command and
dispatch processes. Mobile Knowledges Cabmate system allows all incoming calls to be managed
through one centralized call centre. Computerized dispatch and fleet control
messages in the form of data and voice communications can be sent to the entire
fleet or to specific cabs in a geographic area, over a wide area network
provided by Sprint Canada. Using the technology, central dispatch can track
the position of each taxicab in the entire fleet at any given time. Weve seen this model work with great success in the United Kingdom, said
Hanif Patni, chief executive officer, Coventry Connections. This innovation
coupled with new cabs and improved passenger information systems allows us to
radically change and advance the taxi business. Backed by Sprint Canadas
network and using Mobile Knowledges state-of-the-art solutions, were able to
consolidate dispatch services from multiple cities through one centralized
operation and offer more to our customers. With the success of this launch we
are expanding aggressively and aim to be Canadas largest taxi operator within
a year. Were pleased to be part of this ground-breaking solution, added Greg
McCamus, president, Sprint Canada Business Solutions. Our engineers worked
closely with Coventry Connections and Mobile Knowledge to provide a flexible
solution that uses both voice and data technology to develop an important
advance in the taxi industry. This is a great example of the ways in which
businesses can use technology to gain a competitive edge. Mick Chawner, president and chief executive officer, Mobile Knowledge, said,
We are very encouraged by the success of this initiative. Coventry Connections
can now offer their services across larger distances with far lower operating
costs than previously possible. Weve worked directly with Sprint Canada and
Coventry Connections to certify the reliability and integrity of data
transmissions. We are very pleased with the high data quality and low latencies
observed over the Sprint Canada network. Coventry Connections currently services over 850 taxicabs in Ontario under
various brand names, the largest of which is Blue Line Taxis. Using its base in
Ottawa, Coventry has already launched a premium taxi service with uniformed
drivers and in-cab passenger displays in Oshawa and will shortly integrate
Veterans Modern Cabs in Cornwall. The company is currently in negotiations to
expand into several additional markets in Ontario. About Coventry Connections Inc.
