Verizon 4G WiFi hotspot, Novatel MiFi 4510L

September 28th, 2011

My experience having Verizon-provided internet access over cellular data protocols to my cruising sailboat spans three years and five devices, the Verizon 4G LTE MiFi built by Novetel released this summer being the most current. They’ve worked well enough that I’ve never messed with a high power boat WiFi system, like Ben has, but they are not perfect…

Mobile hotspots are gadgets a little bigger than credit cards that combine a mobile broadband modem with a WiFi router to allow computers and other devices to get onto the internet across distances of 20 miles and more. They have upfront and monthly data plan costs very similar in price to a smartphone.

My first experience surfing the internet through Verizon was in the days before mobile hotspots were available. Back then it was with a tiny card I installed as an option into my wife’s Lenovo ThinkPad laptop and a Verizon USB dongle I used for my own laptop. Both used a cellular protocol called EvDO with average data transfer speeds in the 1 Mbps down, and ½ Mbps up range. Three years ago I found it consistently much faster than the Wi-Fi signals barely in range of my boat despite a powerful Wi-Fi access point provided by the cable company nearby. In addition, the Verizon product received a strong signal out in the middle of Long Island Sound and virtually every anchorage I visited between New York and Maine (see my reviews in www.activecaptain.com)

They also worked well below decks in my Beneteau sailboat, easily penetrating the fiberglass to get a connection. Compared to a Rogue Wave or WireAP, there is literally nothing to install, as both devices would draw power from the computer they were installed in.

As good as that sounds, there was a major hassle in using the included software for the hardware. If the laptop went into a deep sleep to save power, or I closed the lid, the EvDO connection did not recover, sometimes requiring a reboot. The software also interfered with the primary benefit of the USB dongle to share the hardware and data plan between computers, because installing that Verizon client on the next computer took time, required learning that specific computer’s idiosyncrasies in switching between internet sources and involved training the user borrowing the USB dongle on how to switch their laptop back to wired or Wi-Fi internet access.

The arrival of the original Novatel MiFi Hotspot to the Verizon network fixed all that. The MiFi replaced software and a physical connection between the cellular transceiver and the laptop, with a built in Wi-Fi hotspot capability to connect up to 5 computers at a time to the Verizon Cellular EvDO network. This made using Verizon much simpler, as Wi-Fi was already configured on my laptop and that of my co-workers. Switching internet sources was no different than switching between WiFi access points. It was now easy to setup and share my data plan.

Life was good until the Droid series of Smartphones became popular, later joined by the iPhone for Verizon, both of which used the same EvDO protocol and frequencies.

At first I enjoyed accessing EvDO from my phone, first a Motorola Droid and later a Droid 2. My Droid 2 incidentally had the same hotspot capability as my MiFi, but I used it rarely as you can’t talk at the same time, also the MiFi could run five hours on a charge and my Droid could not.

But, my enjoyment of EvDO on both devices fell sharply as hundreds of Droids began competing with mine for the same EvDO bandwidth. Rather than having 1 Mbps of bandwidth, which was more than enough for web conferencing and Skype, the speeds I typically experienced dropped to under 100 Kbps, just 10% of the original speed I once enjoyed.

That brings us to the Verizon 4G LTE network and the hotspot from Novatel (Verizon also offers a hotspot from Samsung, a comparison of the two available here). Verizon has a whole new network (click here for a coverage map), using the LTE protocol it markets as 4G (4th generation) with a speed 10x that of 3G. As a new network with few users, it is very fast. I potentially face disappointment a year or two in the future as millions of new devices use this protocol as well, but at the moment life is good again for connecting my laptop to the internet. The laptop incidently does not need to be upgraded or modified in anyway.

With the Verizon 4G LTE Hotspot from Novatel (above) I have access to both the LTE network when it’s available, and the EvDO network as a fallback. The advertised speed of Verizon’s 4G LTE is up to 10 times faster than 3G EvDO, but with EvDO loaded and LTE near empty, I can measure speeds of 70 to 100 times faster. Ten times faster is all I need.

The 4G Novatel hotspot hardware has some improvements over the original 3G Novatel hardware. One of the small differences is the addition of a status display to show battery charge state and signal strength. This is important as the battery life is so much shorter (barely 90 minutes) vs the older MiFi (5 hours). This 4G LTE version can also be charged with the same 12v boat charger or USB cable I have for my Droid phone, rather than a proprietary adapter the 3G required.

I am cautious that my renewed ability to stay connected while on my boat is in jeopardy, however. Even with 10x the bandwidth, someday there will be millions of new devices using this network as happened with EvDO. With a forecast of 120 million new iPhones to be sold in the next year, I am crossing my fingers that the iPhone 5 doesn’t support LTE, as that could hold off the masses for a year. When this Verizon network and it’s equivalent network from AT&T, SPRINT, and others become saturated, it’s not clear what frequencies will next be available to support another 20+ Mbps of bandwidth per wireless carrier.

Actually, I am more than a little cautious. No offense Verizon & Novatel, but I have to say I cannot recommend this or Samsung’s dedicated hotspot product in combination with an LTE (or EvDO) data plan, because it is likely each user will be stuck midway thru a two year subscription plan paying $50 a month for a product that will be very slow as EvDO has become.

What I can recommend, is purchasing a Verizon LTE compatible smart phone with hotspot capability. Why? First, the hotspot capability can be activated for an additional $20 a month on such a phone, no seperate device needed. Second, you can then elect to discontinue using the hotspot feature at any point the data rate gets too slow. The basic data plan you would still retain on your phone will still be useful to check email and run other apps that work well on low bandwidth, just as my Droid 2 works well even on slow EvDO. Finally, unlike EvDO where the phone can only do one at a time, be a hotspot or let you talk, LTE based smart phones are suppose to be capable of acting as a hotspot and a phone simultaneously. That leaves battery life as the only advantage of the dedicated hotspot. But, for a $30 a month premium I would rather carry a battery powered charger around instead.

Al least for my laptop and I, happy days are here again… until people learn about the Verizon 4G LTE network and millions start sharing the network with me. I mean, I am okay with sharing it with you and other Panbots, but listen, you gotta keep this quiet at least for awhile or I will have to go thru the time and expense to install a Wi-Fi booster for my boat.

WiFi Making iPads And Tablets More Attractive Than Laptops

June 8th, 2011

And trends in Western Europe shows that laptop ownership is decreasing drastically, in favour of increasing interest in iPads and media tablets as the next purchase.

IDC’s ConsumerScape 360° survey, conducted in January this year across six countries including France, Germany, Italy, Spain, Sweden and the UK, points to Western Europeans spending an average of three hours a day online, with search and email being the main activities, regardless of the type of device used (smartphone or computer).

Currently, the most common form of PC ownership across Western Europe is laptops/notebooks, with over 58 percent of respondents owning one in Sweden, while countries such as Italy and France show this percentage to be as low as 45 percent, says IDC.

IDC questioned 11,000 respondents as part of its global Consumer Scape 360° Program on topics related to consumer electronics and device ownership, brand attributes, and usage habits.

Meanwhile DisplaySearch said local or non-branded vendors are fast catching up in the tablet world with whitebox tablet PC players increasing shipments from 567K units in Q4′10 to 1.9M units in Q1′11, representing a 235 percent quarter on quarter growth rate.

While Apple remains the leader in the tablet PC market with a 54 percent share, and also leads the segment in terms of usage experience, hardware design and price, the growing size of the whitebox tablet PC market, with nearly a 20 per cent share in Q1′11 is a sign of increasing demand by the mainstream market for tablets.

Price is a significant influence on any consumer product, and tablets currently carry a healthy premium on the cost of the hardware components,” said Richard Shim, Senior Analyst for DisplaySearch.

“The emergence of the whitebox tablet market is an indication that the market is reacting to that premium and trying to give consumers a lower price to drive adoption

Tips to improve Wi-Fi network

October 24th, 2010

Is your home Wi-Fi network giving you a headache? Do you have trouble spots where you just can’t connect? Do Web pages load slowly or only partially?

Fortunately, you don’t have to put up with spotty Wi-Fi. Here are some insider secrets to improve your network.

Select The Right Location

Placing your router in the best location goes a long way to improving your signal. Routers’ omnidirectional antennas broadcast the signal in all directions. Install the router in the center of your home.

Watch for obstructions. Walls, floors and metal interfere with wireless signals. So place the router as high as possible. Move it away from walls, metal filing cabinets and the like.

Replace Router’s Antenna

You may not be able to place the router in the center of your home. Maybe you need to put it at one end of the house, say where the cable line enters. The signal may not extend to the other end of the house.

In that case, replace your router’s omnidirectional antenna with a high-gain one. It won’t improve output; rather, it broadcasts the signal in only one direction. You can aim it exactly where you need it.

Cut Out Interference

Many routers operate on the crowded 2.4GHz frequency. Cordless phones, baby monitors and microwave ovens will cause interference. Avoid placing these and other wireless gadgets by your router or by your computer.

Routers also operate on different wireless channels, similar to the way radio stations use different channels. One channel may be clearer than others. Try changing the channel in your router’s settings. Check the manual for help. Your computer will detect the change automatically.

Check For Updates

There may be new firmware for your router. Firmware is embedded software that controls hardware. Or there may be a new driver for your computer’s network adapter. Drivers are small programs that help computers communicate with peripherals.

Check the manufacturer’s site for updates. They can improve the reception quality. Carefully follow the instructions for updating firmware and drivers.

Check Your Speed

None of these tips helps if the problem is the Internet connection from your service provider. Maybe things are moving slower than your Internet service provider promised. To find out, take a speed test at Speedtest.net.

The test will quickly check the bandwidth and latency of your broadband Internet connection. Compare its numbers against what your ISP promises. If the numbers are lower than what you’re paying for, call your ISP.

Maybe You Need New Gear

If coverage is still poor, it’s time to buy new gear. Stick with a single brand of networking gear. Different brands work together, but you often get a speed boost with gear from the same manufacturer.

Buy from a major manufacturer like D-Link, Linksys, Netgear or Buffalo. Go with 802.11n gear over 802.11g. It is faster and has a wider range.

Before buying anything else, try a wireless repeater. This picks up your router’s signal and rebroadcasts it, giving you wider coverage. Place it halfway between your router and trouble spots. Repeaters cost about $50.

If you replace your router, look for a MIMO model. Multiple transmitters and receivers work simultaneously to improve range and reception. You’ll need MIMO network adapters for optimal performance.

Go for a simultaneous dual-band router. These broadcast on both 2.4GHz and 5GHz frequencies. Old gadgets can connect at 2.4GHz; new 5GHz gadgets can also connect. You’ll experience less interference at 5GHz.

I also recommend a router with a guest network. Also look for a built-in print server and USB ports for attaching network storage. Expect to spend around $200.

Going wireless, the WiFi way!

October 18th, 2010

Millions of Indian households are setting up wireless networks not just for PCs, but for other WiFi enabled devices, too.

Ashutosh Maheshwari, a Mumbai-based marketing professional, started using WiFi about five years ago. Today, he takes pride in the fact that his wireless internet connection allows him to access the worldwide web not only on any one of his multiple computers but also on his TV, his iPod music player, a Windows-based mobile phone and even his game console Xbox 360.

Like Maheshwari, millions of urban Indians are going wireless, all on WiFi. A WiFi network, or a Wireless Local Area Network, enables mobile devices, laptops or any WiFi-enabled appliance to send and receive data within the range of a wireless base station, commonly known as a hotspot. At present, there are a few public places – like airports, coffee shops and restaurants – where you can access WiFi service for free, or for a fee.

All major system integrators in the country have reported that their hotspot deployments have gone up 20 per cent since last year. Growing laptop sales, increasing awareness about broadband and an all-pervasive use of mobile phones for rich content transfers have become key harbingers of the WiFi platform. The ease with which users can connect household devices has been the main reason for the quick uptake of WiFi.

How to install a wifi printer in your home or office

September 28th, 2010

Wifi networks seem to be taking over consumer electronics, and now almost all PC peripherals can be optimised through wifi; from keyboards and mice, to Ethernet and broadband connections. All of this, of course, adds up to a more flexible, clutter-free user experience. The latest components that don’t need wires are laser printers. Playing a far more hands-on role than many PC components, printers often receive a bad reputation thanks to annoying paper jams or running out of ink at a bad time, but these days printers are still an essential element in any office, so turning them wifi is definitely a good idea.

Some wifi printers run on their own IP address as a wifi network client, whereas others are a component of an already established wifi network, however they all operate in much the same way. To install a wifi printer in your office or home, you need very few materials and even less time. Once you have your PC and printer, all you need is a wifi adaptor (which most PCs come with today), a driver installation disc for your CD or DVD drive and then just an established wifi network which, again, most homes and offices use as standard today.

On your PC, select the ‘Control Panel’ from your ‘Start’ menu and go to the ‘Printers and Faxes’ option. As you would do when installing any printer, click the ‘Add a printer’ option from the Printer Tasks menu and click ‘Next’. At this stage you will most likely have to create a new port using the ‘Standard TCP/IP Port’ connection, after which click to the next page. Next, you have to determine the IP address that your new printer will be assigned to, so that it is distinguished from any other wifi devices your PC might use, and then just click ‘Finish’ to complete the action.

After installing anything new onto a PC, it is generally recommended that you restart the system to prompt the presence of the new hardware. Next put the installation disc into the CD or DVD drive and start it from the ‘My Computer’ option. Open the disc and browse to the installation driver file. Run this file and install it onto your PC, again rebooting once the driver is fully installed.

Once both the printer and the driver are installed and recognized by your PC, it’s time for a test print. Assuming it works fine, then you are nearly finished, you just have to consider the best place to put the printer. Obviously with wifi printers you have a lot of options, but, in an office anyway, it should be central to all users, and at a convenient height too; ideally with room for a paper and ink supply nearby.

With new iPods, smaller isn’t better

September 25th, 2010

ROB PEGORARO
The iPod isn’t even nine years old. But that’s been enough time to dull the marvel of a pocket-size device that costs less and holds more music than many CD racks.

Each year, Apple’s lineup of media players gets a little smaller, and each year the results — while evidence of extraordinary engineering — don’t quite make the case for upgrading.

The latest crop of iPods, introduced Sept. 1 at a media event in San Francisco, shows that a miniaturization mind-set still rules at Apple. But it also shows that gadgets can be too small.

Consider the most compact in the new lineup, the iPod Shuffle. It’s a wafer of a device — about 3.5 cm long — and unlike its immediate predecessor, it includes a set of physical buttons to control playback.

But on this model, $49 for about two gigabytes of flash-memory storage, there’s almost no room outside those controls to undo the clip without pressing the previous-track button. Using its clever VoiceOver spoken-word interface (which gets around the lack of a display by reading titles of songs and playlists to you) requires pressing a tiny, unlabelled button.

Like every Shuffle but the first version, the new Shuffle relies on a non-standard variant of Apple’s proprietary iPod cable; try not to lose it.

The even more problematic iPod Nano ends a history of steady improvements to this flash-memory player. Although this year’s model is smaller than its tiny ancestors, it had to sacrifice their elegant, efficient ClickWheel controls to fit into the case.

In their place you’ll find a touch-sensitive screen that looks terrific but can be a mess in daily use. Numerous actions require skipping back and forth between menus with gestures of varying intuitiveness — forget using it without looking at the display. Its nearly square shape also means you’ll likely be looking at a sideways screen until you flip the display into the correct orientation with a two-finger gesture.

Past Nano models have made good running companions, but forget about this one — even if it incorporates a nifty pedometer application and supports Apple’s Nike+ run-tracking technology. In the winter, you’ll need to remove your gloves (or buy special touch-screen-friendly models) to tap its icons.

The new Nano also nixes not only the older unit’s ability to record video, a defensible move, but also its video-playback options. Considering the features jettisoned from this model, it almost looks like a research project that was meant for focus-group testing but somehow escaped to volume production.

Only the updated iPod Touch represents a major advance. This WiFi-enabled gadget catches up to the new iPhone 4 in a variety of areas. Its screen offers the same absurdly high 960-by-640 pixel resolution; its faster processor and upgraded motion sensors let it play the same games as the iPhone 4; it includes video-capable cameras on the front and back; most importantly, it adds a microphone.

That last feature allows you to use the new Touch — within areas of WiFi access — as a sort of AT&T-liberated iPhone. Beyond browsing the web and checking your e-mail, you can place and receive phone calls with Skype and other internet-calling programs (pity that Google’s Google Voice is not among them) and stage video conferences with iPhone 4 owners and other Touch users in Apple’s FaceTime software.

The cameras on the Touch can record 720p high-definition video, but they’re woeful for taking still photos, thanks to their low resolution and fixed focus.

For still more capacity, you’ll have to buy the 160 GB iPod Classic.

While Apple has been tinkering in less-than-useful ways with its media-player inventory, the rest of the market has been evolving. Most smartphones now come with music-playback software that does the basics passably well- certainly as good as the new Nano. With the demise of proprietary “digital rights management” controls on iTunes Store music, the only thing tying you to Apple’s music lineup is Apple’s iTunes program, which will only sync music to iPhones or iPods.

But Apple’s developers seem to have lost their way with the new iTunes 10. Its Ping social-networking feature doesn’t connect to other networks — forget looking up Facebook friends — and can’t even be used from outside iTunes. It is just as closed and limited as Apple’s mediocre, expensive MobileMe data-syncing service.

In terms of performance and interface, iTunes 10 manages the rare feat of fitting poorly in Windows while also looking like a misfit in Mac OS X.

The iPod Touch has considerable potential as a miniature mobile communicator. But as far as music playback goes, the iPod might be nearing the end of its white headphone cord.
