Belkin Wireless Pre-N Router
Vendor Belkin
Product type 'pre-N' wireless LAN router
Functionality profile MIMO antenna technology uses a single channel for multiple data streams, greatly enhancing both range and throughput; DHCP server; WEP and WPA security; firewall with SPI and NAT; VPN pass-through
Performance profile Theoretical maximum throughput of 108Mbps (compared to 802.11g's 54Mbps); double the range of 802.11b/g gear; improved performance in mixed 802.11b/g/pre-N networks
Usability profile Printed setup guide and CD-based wizard make installation straightforward; Web-based interface for router management
Price £70 - £100 (inc. VAT)

The 802.11n standard is still being ironed out, and the IEEE (Institute of Electrical and Electronics Engineers) doesn't expect to ratify this developing specification until 2006. However, products based on competing versions of 802.11n's powerful smart-antenna technology, called MIMO, are already available. One of the best of these is Belkin's Wireless Pre-N router.

 

MIMO stands for Multiple Input Multiple Output, and allows a wireless device to make more efficient use of data transmissions in indoor environments. The 802.11n standard will include some version of MIMO, and it promises to deliver 108Mbps throughput and double the range of today's Wi-Fi gear. The smart antennas on a MIMO router can hand off reception and transmission dynamically to each other, adjusting for the clearest data path on the fly. This increases both range and throughput at any given distance in an indoor setting, especially in multipath or interference-prone environments.

Because early 'pre-N' products such as Belkin's are based on proprietary solutions rather than a ratified standard, mixing and matching gear across vendors typically results in degraded performance. Also, when 802.11n becomes a reality, today's Pre-N/MIMO solutions probably won't be fully interoperable with gear based on the ratified spec.




Vodafone Mobile Connect 3G/GPRS data card
Vendor Vodafone
Product type 3G data card for notebook PCs
Functionality profile PC Card hardware and Dashboard software allow a notebook PC to connect to Vodafone's 3G data network, providing near-broadband Internet connectivity with coverage concentrated in major UK towns and cities; where 3G is not available, a slower GPRS connection is used
Performance profile Maximum download speed of 384Kbps (contended service, with actual performance dependent on the number of cell users)
Usability profile Straightforward installation and setup; Dashboard application provides one-stop interface to datacard features
Price Card price from £199 to free depending on tariff; monthly charge from £11.75 (5MB tariff) to £53 (1GB tariff); beyond-tariff data costs from £2.35 per MB to zero; international roaming incurs extra charges

Vodafone's Mobile Connect 3G/GPRS datacard provides notebook PC users with near-broadband wide-area connectivity via a third-generation (3G) cellular network. It comprises a Type II PC Card with a SIM slot, CD-based installation software and a detachable aerial that plugs into the card.

Vodafone’s 3G data service supports a maximum download speed of 384 kilobits per second (Kbps), or 48KB of data per second, and testing by ZDNet UK regularly achieved speeds of around 264Kbps (33KB/s, or around 2MB a minute). Like DSL, 3G is a contended service, so bandwidth is shared between the various 3G users in each cell. Coverage is centred on major cities, and where a 3G link is not available the connection falls back to dial-up-modem-speed GPRS.

It's worth noting that a 3G datacard is currently an expensive mobile connectivity solution; also, users have reported issues with notebook compatibility, technical support, 3G coverage and 3G/GPRS handover.



Windows Mobile 5.0
Vendor Microsoft

Functionality profile Good platform flexibility (supports landscape screens and QWERTY keyboards) and wireless connectivity options (including 3G); persistent memory storage; bundled Mobile versions of MS Office software; hard drive and USB 2.0 support
Performance profile Requires ARM-based CPU, 32MB Flash ROM, 64MB SDRAM; support for persistent storage boosts battery life
Usability profile Windows Mobile 5.0 has the look and feel of desktop Windows, and should be familiar to most users; it comes with 3 handwriting recognition choices, keyboard support, soft-key integration and virtual input area to maximise screen space
Price OS is bundled with hardware (no devices released yet)

Released in May but yet to appear in any shipping devices, Windows Mobile 5.0 is designed to provide handheld and smartphone manufacturers with a more solid platform on which to build their devices. Hardware manufacturers will be able to create devices in many different form factors, incorporating QWERTY keyboards, landscape display orientation and soft-key integration. There is also support in version 5.0 for a wider range of wireless technologies, such as 3G and Wi-Fi for smartphones, plus improved Bluetooth support.

Windows Mobile 5.0 now has built-in support for persistent storage, so that when the battery drains completely, your data remains intact. This means that you can expect longer battery life, as the device won't have to allocate any power to maintain the information stored on it.

Popular Microsoft Office applications such as Word and Excel are bundled as Mobile versions: Word Mobile now supports tables, lists and embedded images, while Excel Mobile allows you to create charts and graphs. There's also PowerPoint Mobile, which allows you to view Presentations (but not edit them). Outlook Mobile provides access to corporate and POP email, and now lets you access Hotmail and MSN in-boxes too.

Microsoft has recently announced a Messaging & Security Feature Pack for Windows Mobile 5.0 that will leverage new functionality in Exchange Server 2003 SP2 to deliver features like push email, device passwords, and over-the-air provisioning and data wiping.
