UMTS (WCDMA) Technology

Universal Mobile Telecommunications System is a third generation (3G) mobile communications technology that is being developed into a 4G technology. It is specified by 3GPP and is part of the global ITU IMT-2000 standard. The most common form of UMTS uses WCDMA (Wideband Code Division Multiple Access) as the underlying air interface. The UMTS technology instigates authentication of users via USIM cards (Subscriber Identity Module).

Offering mobile speeds up to 21 Megabits per second (21 Mbps) with HSPA and HSPA+ technology, the network covers 1.2 million square kilometres, reaching approximately 20,000 Canadian towns and cities and 93% of the population. The HSPA and HSPA+ network also supports international roaming in more than 200 countries and data services in more than 170 countries and across the United States.


High Speed Packet Access (HSPA) is a collection of two UMTS (Universal Mobile Telecommunications System) telephony schemes High Speed Downlink Packet Access (HSDPA) and High Speed Uplink Packet Access (HSUPA) that extend and improve the performance of existing WCDMA (Wideband Code Division Multiple Access) protocols. HSPA offers peak data rates up to 14.4 Mbps download and 5.8 Mbps upload. HSPA+ improves the end-user experience by increasing peak data rates up to 21 Mbps download and 5.8 Mbps upload.

These faster data speeds unleash a whole new range of applications just not possible at lower speeds such as streaming video and multimedia-rich applications that demand broadband links. Business users can experience faster downloading when accessing the Internet and retrieving e-mails, including large attachments and other bandwidth-intensive applications.

CDMA Technology

Both the 1xRTT and EVDO networks are based upon CDMA (Code Division Multiple Access) which is a digital wireless technology that was pioneered and commercially developed by Qualcomm. Using a unique code to distinguish each different data session, CDMA enables many users to share the airwaves at the same time. CDMA consistently provides enhanced capacity management for voice and data communications, allowing more subscribers to connect at any given time, and it is the common platform on which 3G technologies are built. Another advantage of the CDMA environment is the use of Spread Spectrum for maximum bandwidth optimization. Spread Spectrum technology originated from military applications and it offers a high level of security for over the air transmissions.

Bell Mobility’s CDMA coverage offers access to 1xRTT and EVDO technology. With the Bell Wireless Alliance, MTS, SaskTel and other Canadian partners, Bell Mobility offers Canadian national coverage totalling 1.5 million square kilometres. This national coverage provides the users with a seamless experience across the entire country. Bell Mobility’s EVDO is Canada’s largest EVDO footprint offering download speeds of up to 3.1 Mbps.

CDMA 1xRTT technology has the capability to support both voice and data services over a standard (1X) CDMA channel. It provides up to twice the capacity of earlier CDMA networks, helping to accommodate the continuing growth of voice services as well as new wireless Internet services. 1xRTT is a full duplex, 2-way packet data network based on the Internet Protocol (IP) standard.

Bell Mobility’s 1xRTT network is Canada’s largest network covering 98.2% of Canadian population with 1.5 million sq.kms of the coverage. The 1xRTT network has a peak download data rate of 144 Kbps.


EVDO stands for Evolution Data Optimized and is a data only cellular network. ‘Data only’ means that the EVDO network is dedicated to wireless data needs, including e-mail, opening attachments, accessing corporate Intranets or the Internet and using feature rich applications. Bell clients can enjoy broadband-like speed, wirelessly, wherever their business takes them.

Bell was the first in Canada to offer wireless broadband with our EVDO network. EVDO offers end-users unprecedented wireless data transmission speeds.

Bell Mobility employs Rev A of the EVDO release which is a leading-edge wireless technology that adds even higher data rates and higher system capacity, as well as improved QoS support for low-latency packet applications. It is a fully backward compatible standard and remains interoperable with deployed EVDO networks and devices around the world.

The Rev A network has a peak data rate of 3.1 Mbps download and a peak data rate of 1.8 Mbps upload.

In-building Coverage

Bell Mobility provides complete engineering services to deploy in-building systems in the situations where indoor coverage is required but the network signal is weak. Bell Mobility can do a site survey to assess the indoor coverage and Bell Mobility can provide in-building repeaters which will boost the indoor signal strength. Handheld devices would then be able to fully access the Bell network while indoors. In-building projects are undertaken based on a positive business case.

In-building requests need to be evaluated on a case-by-case basis since each building has different radio signal penetration characteristics. The in-building repeater design, cost and implementation time can vary widely based on the characteristics of the building structure. Funding for in-building projects can consists of a contribution from the customer and a contribution from Bell.

Network Security

Bell Mobility offers an end-to-end network approach to security that not only ensures network security but overall network reliability and resiliency to allow business continuity. Code Division Multiple Access (CDMA) technology originated from military applications and cryptography, and to date, do not have any report of high jacking or eavesdropping on a CDMA call in a commercially deployed network. The inherent security of the CDMA air interface comes from spread spectrum technology and the use of Walsh codes. CDMA utilizes specific spreading sequences and pseudo-random codes for the forward link (i.e. the path from the base station to the mobile) and on the reverse link (i.e. the path from the mobile to the base station).

These spreading techniques are used to form unique code channels for individual users in both directions of the communication channel. Because the signals of all calls in a coverage area are spread over the entire bandwidth, it creates a noise-like appearance to other mobiles or detectors in the network as a form of disguise, making the signal of any one call difficult to distinguish and decode.

CDMA also has a unique soft handoff capability that allows a mobile to connect to as many as six radios in the network, each with its own Walsh code. This means that someone attempting to eavesdrop on a subscriber’s call has to have several devices connected at exactly the same time in an attempt to synchronize with the intended signal. In addition, CDMA employs a fast power control, 800 times per second, to maintain its radio link. It is difficult for a third party to have a stable link for interception of a CDMA voice channel, even with full knowledge of a Walsh code. Synchronization is critical, as without this synchronization, the listener only hears noise.

Bell Mobility also can enhance security by the use of private IP address pools and dedicated VPN connections. A dedicated private IP address pool will prevent the customer’s modem from being able to access the Internet and will prevent spam attacks from the Internet. A Virtual Private Network (VPN) connection between the Bell Mobility network and the customer’s private network provides a dedicated tunnel for the data to securely travel between the customer’s modem and the customer’s network.

Bell Mobility works within best practices as described in ISO standards for information security management.

A Section 5900 (CICA Handbook) assessment of Bell Mobility’s wireless data path is carried out annually by external auditors.

Bell has announced that LTE (Long Term Evolution) will be the technology for our fourth generation (4G) network. This 4G network is the next evolution to Bell’s current 3G technologies which include EVDO, HSPA, and HSPA+ and will deliver mobile data speeds as high as 100 Megabits per second and a new era of services and devices.

The new 4G network will be introduced in a two phased approach:

  1. Continued investment in our current 3G (EVDO) network and roll out of a new high speed packet access (HSPA) network overlay. HSPA technology is a precursor to LTE.
  2. Evolve the HSPA network to a full 4G network as the LTE industry standard becomes fully developed post-2010.

The following are the average speeds which an HSPA network is capable of delivering:

These speeds are dependent upon device and network configurations.
