Data transmission | Nokia 9500 instruction

22.Data transmission

This device employs the data transmission capabilities of the GSM and WLAN networks to send multimedia messages, short messages and e-mail, and to establish connections with remote computers, for example.

Wireless data connections can be made from most locations where your device operates, but it is recommended that you move the device to a location where the strongest possible wireless signal can be obtained. When the signal is strong, data transmission is efficient. Wireless data communications may perform differently from data communications transmitted over wires. This is due to the inherent characteristics of the wireless environment. Wireless connections may experience "noise", low or lost signals, and distortions.

Noise

Radio interference from electronic appliances and equipment, as well as from other phones may affect the quality of wireless data transmission.

Roaming

As the device user moves from one network cell or WLAN access point coverage area to another, the signal strength of the channel may drop. The network may hand over the user to a coverage area and frequency where the signal is stronger. Network roaming may also occur when the user is stationary, due to varying network traffic loads. Such roaming may cause slight delays in transmission.

Electrostatic discharge

A discharge of static electricity from a finger or a conductor may cause erroneous functions in electrical devices. The discharge may result in distorted display and unstable software operation. Wireless connections may become unreliable, data may become corrupted, and transmission halted. In this case you need to end the existing call (if any), switch off the device (if on) and remove the battery. Then replace the battery and establish a new wireless connection.

Dead spots and dropouts

Dead spots are areas where radio signals cannot be received. Dropouts occur when the device user passes through an area where the radio signal is blocked or reduced by geographical features or large structures.

Signal impairment

Distance and obstacles can cause signals to become out-of-phase. They can also cause reflected signals. Both situations result in a loss of signal strength.

Low signal strength

Due to either distance or obstacles, the radio signal strength from a WLAN access point or a cell site may not be strong enough or stable enough to provide a reliable data connection for communication. Therefore, to ensure the best possible communication, remember the following points:

•The data connection works best when the device is in a stationary position. Attempting wireless data communication while in a moving vehicle is not recommended.

•Do not place the device on a metal surface.

•Check on the device display that the signal strength is sufficient. Moving the device within a room, especially towards a window, may result in a stronger signal. If a signal is not strong enough to support a voice call, data connection should not be attempted until you can find a location with better signal reception.

9500 specifications

The Nokia 9500 Communicator, launched in 2004, stands as a landmark device in the evolution of mobile technology, blending the features of a smartphone with the functionality of a handheld computer. It was part of Nokia's Communicator series, which was known for its advanced features, and the 9500 was particularly significant due to its innovative design and robust capabilities.

One of the standout features of the Nokia 9500 is its distinctive clamshell design. When closed, it resembles a traditional mobile phone, compact and easy to carry. However, upon opening, the device reveals a full QWERTY keyboard and a large display, offering an exceptional typing experience for those who frequently send emails or create documents on the go. The keyboard is spacious and tactile, making it ideal for productivity tasks.

The 9500 is equipped with the Symbian OS, specifically the Series 80 user interface, which was optimized for the Communicator's unique form factor. Users could multitask efficiently, switching between applications seamlessly, which was a remarkable feature for its time. It supported various productivity applications including calendar, contacts, and word processing, enhancing its appeal to business users.

In terms of connectivity, the Nokia 9500 offers a range of options. It includes support for GPRS, providing users with internet access even while on the move. Wi-Fi capabilities further expanded its utility, allowing for faster data transfer rates and easier access to the internet in hot spots. Bluetooth technology was also included, enabling wireless data sharing with other devices.

The device features a 640x200 pixel display, which was impressive for its time, ensuring that both text and images were clear and easily readable. The Nokia 9500 also came with a camera, which was a novelty for mobile devices in the early 2000s, allowing users to capture images on the go.

Another important aspect of the 9500 is its battery life. It was designed to support extended usage, making it a reliable choice for professionals who needed to stay connected throughout the day. The device also supported expandable memory through a miniSD card slot, providing further flexibility for users to store more data.

In summary, the Nokia 9500 Communicator was a pioneering device that combined the functionalities of a mobile phone and a laptop. With its robust design, keyboard, productivity applications, and connectivity options, it set a foundation for future smartphones, showcasing what mobile computing could achieve long before the era of modern smartphones.
