Choosing a mobile device these days can be confusing – let’s take

a look at the configuration options available:

Communications Options

• Wireless Communications

• HSDPA and HSCSD are 3G
• GPRS and EDGE : Wireless Wide Area Networks WWANs maintained by major public carriers like Cingular, Sprint

  Nextel, T-Mobile, and Verizon in the United States. Throughput is variable but I see around 300 KBPS in most markets. Each carrier offers an

  unlimited data plan for approximately $25 USD per month. GPRS is a subset of GSM. EDGE is an enhanced GPRS compression that allows greater bandwidth

  over GSM timeslots.

• WIFI : Wireless Fidelity or Wireless Local Area Networks WLANs known as 802.11a,b,g, and the latest g chips are

  included in many mobile devices. These privately maintained networks have low overhead costs and a range of around 300 meters with throughput up to 54

  MBPS – greater in proprietary manufacturer-introduced multiplexing configurations.

• Bluetooth : Personal Area Networks PANs are designed

  to connect personal devices to one another in a range of 30 meters in enhanced mode.

In your home office – internet connectivity is the second most

important utility, right behind electrical power. When you do fall off the grid, however, the best way to not completely loose it is to have a plan in

place. I have four stages of redundancy to make sure I can always hit the net before I give up and miss a demo – your sales team will appreciate it!

1) Power down and reset everything. About half of the broadband outages are resolved by reconnecting to the service. If that

doesn’t work, most likely these days there is an outage – and most providers don’t even notice an outage until they get 10% reported down on a node.

Keep your provider on speed dial on your mobile or non-VOIP phone, just to check, then when they tell you it will be next week before they can roll a

truck, politely make the appointment and move on to step 2 below.
2) Scan the airwaves! Just right click on your wireless

networking icon and choose “view available wireless networks”.
