Boost Your Cell Phone Coverage

Cell Phone Boost That Works

You might have seen stickers that you put on the back of your phone. They supposedly improve coverage, but they work just about as well as hope. This is better than that. It’s the zBoost Cell Phone Signal Booster.

The zBoost Signal Booster is equipment that you need to install at your home or office (now there is a car model too).  It consists of two parts:

  • Antenna to pick up the signal. It is in 16 inch by 1 inch PVC pipe
  • Booster that you place where you need the signal to go. It is about the size of a router or cable modem.

The antenna and booster are connected by a coaxial cable. There are different zBoost models costing $215-$310 depending on the cell carriers you need boosted. Be sure to get the right model for your needs.

If you read the reviews on Amazon, you will see that most people either love it or hate it. This is based on the individual situation in a particular location. You need to have coverage somewhere so that you have a signal to boost. The ideal location is typically on a roof or a window. Then you put the booster where you need coverage, which is recommended to be at least 25 feet away from the antenna in order to reduce interference.

My Experience

I just installed the zBoost for someone in Arlington, Virginia. It was the dual-band 800 and 1900 MHz XY510 model because they have iPhone 3G’s, which use both bands depending on if they are on AT&T’s Edge or 3G network. Their living room went from no coverage to 5 bars. Be sure to follow the instructions closely and experiment with placement. In my case, changes of 1 foot for the receiving antenna made a difference of 3 bars.

If your home or office has poor cell phone coverage, this could be well worth the investment.

Problems for Pandora and other US Web Radio Stations

Pandora is a web site that provides streaming music to your computer, your iPhone, and other devices. It creates customized stations based on music you like and if you give a song a “thumbs up” or “thumbs down”. You can click on a song you like to go to Amazon or iTunes in order to purchase it. It’s great for finding new music and it used to be a good business.

But the record companies are afraid of streaming radio stations. They brought the issue to the Copyright Royalty Board, which decided last year to raise the cost to play a song over the Internet from 8/100 of a cent per song per listener in 2006 to 19/100 of a cent per song per listener in 2010. Pandora only makes revenue on ads on its website, so this will be quite a bite into profits.

The Washington Post recently talked with Pandora.

“We’re approaching a pull-the-plug kind of decision,” said Tim Westergren, who founded Pandora. “This is like a last stand for webcasting.”…

“We’re losing money as it is… The moment we think this problem in Washington is not going to get solved, we have to pull the plug because all we’re doing is wasting money.”

The problem is in Washington with the Copyright Royalty Board’s decision. First, if the music industry understood what was in their best interests, they would encourage the promotion of their music. Second, these rules only apply to the US. So I can still listen to streaming radio coming from Canada or anywhere else. Only US-based sites are punished. Third, no fees are charged to traditional over-the-air radio stations to play music.

Rep. Howard L. Berman of California is trying to negotiate a deal between web radio companies and SoundExchange, which represents the record companies. Hopefully he can encourage a more reasonable approach to music over the Internet.

My MobileMe Experience

Oh My, MobileMe

You’ve probably already heard of the disastrous launch of Apple’s MobileMe service. Apple has taken a lot of heat for this and heads have rolled over at Apple HQ for it. There are still some remaining issues to be fixed but for the most part Apple has gotten MobileMe working. I’m currently using a free MobileMe trial to evaluate it to see if it will meet my needs. The biggest of my needs is getting all of my emails from several accounts on my iPhone as quickly as possible.

Push Email

If you use a standard POP or IMAP email account, you are limited to a 15 minute check frequency in the iPhone Mail application. In addition to that limitation, if you set up multiple accounts, it will drain your battery all the quicker. My solution was to set up just one account on the phone and have all the email accounts I want to get mail from forwarded to that one. MobileMe is the perfect choice because it offers push email. Instead of that 15+ minute wait for new mail notification, push means you get near instant notification of a new message. In my experience, near instant means about 10 seconds or less.

When MobileMe launched, it was simply unreliable. Some of my messages would arrive instantly, others would never notify me without opening the Mail app. Besides a couple of bad days this month, things have worked far more reliably lately although I still manually check the mail if I haven’t gotten any notifications in a while. Once I had my MobileMe account set up on the iPhone, I still had to get all my email accounts forwarding to my username@me.com email address.

VersaForward to Forward Email

I use Email Forwarding by VersaForward Service to get all my mail to my me.com address. You can set up all of your email accounts to forward to the email address you check on your iPhone. This is a service with a fee paid monthly or every 6 months. To get a discount, use the promotional code TECHDC when signing up for a free trial. That will give you 50% off the first 3 months. Alternatively, you can run home desktop versions of VersaForward either with the entry-level VersaForward Personal or the more powerful VersaForward Professional.

Once you’ve got your email forwarding set up, you can get all of your email messages on your iPhone in a timely and reliable fashion.

Other MobileMe Features

MobileMe does cost $99/year although it offers more than just an email address. Push contacts and calendar updates help keep your iPhone, Desktop, and laptop all up to date with your latest changes. The MobileMe Gallery is a very elegant photo sharing system which creates a website with your photos to share with others as you want to.

Besides mail, my favorite MobileMe feature is iDisk. You can basically consider this a hard drive that you have access to on your computer but the data is stored on the internet. It is the simplicity of iDisk on your computer that makes this so useful. It appears like an external hard drive would. Drag files to it like normal. You can log in to me.com to access the files on the iDisk so it is a great place to keep important files that you might need remote access to. You have a total of 20GB of storage on MobileMe. You can allocate this between email and data storage. The iDisk can work with Macs and Windows as well.

Give Me a Chance

MobileMe got off to a slow start but now that it is finally working, you can see the advantages that it offers. For me, the push email is the #1 selling point. As long as it continues to work, I expect to become a paying customer. The free trial lasts 60 days so you can try it yourself to see how you like it.

VNC and DynDNS for Remote Desktop Support

Connecting Remotely with VNC

One of my favorite software tools to use at Tech DC is VNC. If I have a client in Maryland, D.C. or elsewhere in the world when I am in Virginia, I can use VNC to take control of their computer in order to remotely diagnose problems or provide user training.

VNC stands for Virtual Network Computing. It was originally developed by AT&T Labs in Cambridge, England. It is open source and free. There are many “flavors” of VNC that use the VNC protocol. My favorite for Windows is UltraVNC because it has the added feature of allowing file transfers between the two machines. VNC exists for Windows, Mac, and Linux.

VNC has two parts. There is the VNC Server which serves up the image. And there is the VNC Viewer which views and controls the server computer.

DynDNS.org

One limitation is that VNC requires a static IP. This is where DynDNS.org helps. Most home internet connections have a dynamic IP address, meaning that the IP address changes occasionally. DynDNS.org creates an address such as “yourname.dyndns.org” that is always mapped to your latest IP address, so it is as if you have a static home IP address.

UltraVNC’s Single Click

It takes extra time to setup, but Single Click is a great tool that can be built at UltraVNC. It is a small executable file that someone can click on in order for you to take over their computer. This makes it simple for the person you are connecting to. It also has the added benefit of not needing to configure their router to forward port 5900 to their computer. Single Click is only available for Windows computers.

All Free

VNC is free and DynDNS has a free service that is all you need. You can purchase other remote connection tools that are sometimes easier to set up such as GoToMyPC.  But if you can configure them, VNC and DynDNS should provide everything you need to connect to remote computers.

Erasing Your Hard Drive with Apple’s Disk Utility

If you attach a hard drive to a Mac OS X computer, you can erase it using the built-in Disk Utility.

The cheapest way to attach an external drive is with an adapter such as this one for IDE hard drives from Newegg for about $18.

Once connected on a Mac OS X computer, click Go – Utilites – Disk Utility. From there, click on the disk you want to erase, click the Erase tab at the top, then click Security Options. This will give you the following options:

Zeroing out the data will erase it. For added security, choose the 7-Pass or 35-Pass options to overwrite the data in multiple passes. Like Darik’s Boot and Nuke utility, this will ensure that the data can not be recovered even if someone is using special forensic recovery software.

Once you choose the option you want, click Erase. That’s it.
