wWAN is a carrier operated cellular network that transmits both voice and data

wWAN technology is divided into three types:

– _AMPS

– _2G_{(second generation) – circuit-switched voice & data}

– _CDPD

– _2.5G_{– HSCSD packet-data service enhancements to the}

– _{GSM, TDMA, CDMA and PCS}

– _3G_{(third generation) – re-designed for increased capacity,}

speed and efficiency they carry both voice and data, and can provide +/- 144Kbps

– _{GPRS and CDMA2000 (1xRTT)}

wLAN & wWAN Comparison

Feature Wireless LAN Wireless WAN Geographical Coverage

Area

Small: Typically in building or campus. Some cold spots may prevent network access but typically these can be addressed.

Large: Can be Nationwide. Cold spots may prevent network access.

“In Building” coverage Typically very good assuming the access points are setup properly.

In a building with leaded glass, reflective windows or thick concrete walls, coverage can be poor except close to windows. Large buildings can also cast a shadow blocking out signals behind it.

“In Vehicle” coverage None - Unless the vehicle is in a covered building or campus.

Typically works well, even when moving.

Throughput High (11-50 Mbps) but often shared by many users Moderate, but typically each user gets between 50-144Kbps on the newer faster GPRS networks Latency Low, typically less than 10mSec. High, typically 300-1000mSec

Setup Cost Low to moderately expensive to cover a large building or campus.

Access card costs are relatively small and sometimes free with service.

Setup Complexity Relatively easy for small one access point network. Can be complex for large building or campus – expert will likely be needed.

Easy, the carriers have done the hard work setting up the network for you.

Usage Cost Free airtime, though system maintenance and troubleshooting is an ongoing expense.
