1.2 Evolution of Cellular Networks
3G Technologies
3G refers to the third generation of telecommunication technologies that is designed to replace 2.5G (GPRS
or CDMA). The demand for 3G comes from the growing need for data transmission over wireless networks.
The features of cellular networks make them particularly attractive to wireless users in comparison to IEEE
802.11 standards. Cellular has the advantages of wider coverage and the ability to stay connected in high-
speed movement. To satisfy the need for data exchange over cellular networks, 3G networks were developed
to improve spectral efficiency. The improvements incorporate voice, video, and broadband wireless data
transmission all in the mobile environment.

The most commonly seen 3G systems are the Universal Mobile Telecommunication Systems (UMTS) and the
Wideband Code Division Multiple Access (WCDMA). These 3G systems are the major revenue contributors
to carriers in the past three to two years. As the technologies continue to evolve, transmission speeds have
become faster. For example, High Speed Packet Access (HSPA) offers downlink speeds that can reach 144
Mbps and 5.8 Mbps for the uplink. It is not wonder the building of 3G facilities and networks are on the rise.
Worldwide subscribers are expected to increase rapidly over the next 3 to 4 years. However, 4G technologies
are already in the works and aim to take mobile data transmission to an even higher level.

HSDPA
High Speed Downlink Packet Access (HSDPA), or 3.5G, is a mobile telephony communications protocol.
It provides packet data service in WCDMA downlink. The transmission speed can reach 8–10 Mbps on a
5 MHz carrier wave, and 20 Mbps with MIMO technology. In practice, the technologies deployed include
AMC, MIMO, HARQ, fast scheduling and fast cell selection.

HSUPA
High Speed Uplink Packet Access (HSUPA), or 3.75G, was developed in response to the inadequate upload
speed of HSDPA (only 384 Kbps). The transmission speed can reach 10–15 Mbps on a 5MHz carrier wave,
28 Mbps with MIMO technology. The upload speed goes up to 5.76 Mbps, 11.5 Mbps with 3GPP Rel7
technology. With HSUPA, functions requiring massive upload bandwidth (e.g., two-way live transmission or
VoIP) can be realized.

WPAN (Wireless Personal Area Network)
A WPAN is a short-range peer-to-peer or ad hoc network built around a person’s working area. Normally the
distance is no more than 10 meters. Because of their limited transmission range, WPANs are used mainly as
cable replacement solutions for data synchronization and data transmission for personal electronic devices
such as PDAs or smart phones. Bluetooth is the most prevalent WPAN technology in use today. It allows
devices such as phones, mice, headsets, and other personal devices to connect wirelessly within a range of 10
meters. The shorter communication distances also mean lower power consumption, making Bluetooth an even
more ideal solution for short-range data transmission. Moxa will be releasing WPAN products in 2010.
