Arguably one of the most exciting handsets from mobile phone giant Nokia, the Nokia N8 provides a simply stunning list of specifications with impressive hardware. one of the major strings to this handsets bow is the inclusion of an amazing 12 mega pixel digital camera.
The Nokia N8 provides fast Internet access via both 3G coverage and Wi-Fi. in areas covered by 3G, access the Internet is provided courtesy of an HSDPA connection at speeds of up to 10.2 mega bytes per second, along with HSUPA at 2 MB per second. Whenever Wi-Fi detects a signal from a wireless Internet router, it utilises these to provide a much faster browsing experience. in order to stay connected to cellular networks in all but the most isolated locations, class 33 versions of both EDGE & GPRS are utilised.
As mentioned, the Nokia N8 comes equipped with an impressive digital camera boasting a whopping 12 mega pixels. This operates at a pixel resolution of 4000x 3000 pixels and includes Carl Zeiss optics, Autofocus and a Xenon flash, leaving users with no doubts over the cameras quality. Face and smile detection is also included to simplify the task of taking great photos. The increasingly popular geo-tagging facility is also present which utilises GPS to automatically records the location at which a photo was taken. High definition video can be shot using the camera in 720p quality at a rate of 25 frames per second.
16 GB of internal storage is provided as standard which allows plenty of room for data such as media files. although this amount should prove ample for the needs of most users, it can be increased to 32 GB by utilising the micro SD card slot. The internal phonebook can store a seemingly endless number of entries and fields and comes with the popular Photocall function. This allows a photo to be assigned to a particular contact within the internal phonebook, which is in turn displayed on the screen whenever that person is in contact.
The Nokia N8 is relatively compact at 113.5x 59.1x 12.9 mm and weighs in at just 135 g. The combination of compact dimensions and its lightweight makes it a pocket friendly handset which is also comfortable to hold and use on the move.
A huge number of additional features is included as standard within the Nokia N8. This ranges from a versatile internal media player which supports many different formats of both video and music files to a document viewer for business users. Voice command and dial means users can operate many functions simply by talking to the phone whilst GPS with A-GPS support allows various applications to function such as the digital compass and geo-tagging.
The screen on the Nokia N8 is an AMOLED capacitive touchscreen and it measures 3.5 inches. it operates at a pixel layout of 360x 640 pixels can display up to 16M colours for perfect playback of video files and photos. it features an accelerometer sensor for auto rotate and is manufactured from scratch-resistant materials.
Despite incorporating a groundbreaking digital camera, the Nokia has not neglected other areas phone constructing the N8. it offers functionality to rival even the most established Smartphone Brands and excels in areas where others fall short.
We are creatures of habit, and once we get used to doing things a certain way, it really is difficult to change. for some people, this also applies to implementing home VOIP service in their home. unlike traditional phones, where your home may already be wired with a phone jack in the wall in each and every room, your home is probably not wired in the same way for VOIP. but you can still implement VOIP throughout your home, and there are multiple ways to accomplish this.
Let’s look at the component parts of your VOIP system. once you decide which VOIP provider to use, you will get a VOIP adapter box, also known as an ATA box. this box is about the size of a deck of cards and is the smarts behind the VOIP. One cable from this ATA box plugs into a spare jack on your high-speed Internet router, and your standard RJ-11 jack from your regular phone plugs into the other end of the ATA box.
Ok, some of you are saying you have a problem already, since your high-speed Internet connection modem only has ONE jack on it, and that is where you plug your computer in so you can get online. Yes, this is a problem but not a huge one. You are going to need to go to Best buy or Radio Shack or some similar place and get a HUB. the easiest way to think of this is like being an extension cord for your high-speed Internet modem. You plug the hub into an electrical outlet, and then you run a cable from the hub to the jack on your high-speed Internet modem. now you plug your computer into one of the jacks on the hub (you will probably have about 3 or 4 of them), and also plug the cable from your VOIP ATA box into another jack on the hub. Before you leave Best buy or Radio Shack, make sure you have the cables with RJ45 plugs on each end – one of these goes from the hub to your modem and another one goes from your VOIP ATA box to the hub.
Now with your VOIP ATA box connected to the hub or directly into your high-speed Internet modem if you had a spare jack on it, you just connect your standard traditional phone into the RJ-11 jack on the ATA box and you are good to go.
But what about using your VOIP phone throughout the house so that you are not tethered to the room that has the ATA box and the high-speed Internet modem? You have multiple options here. You can use a cordless phone where you would plug the base unit into the VOIP ATA box, and then you are good to go. I would recommend a cordless phone that is in the 5.8 Ghz range to provide your best coverage.
If you want to have multiple phone handsets around the house, I would recommend getting one of those multi-unit cordless phone setups. Some of those can accommodate up to 8 cordless phones with the same base unit.
There are places online that will explain how to wire your VOIP ATA box into the outside wiring of your home phone system so that the RJ-11 jacks you already have in every room can still be used. while this is possible, it is not recommended. there are multiple stories of people who have blown out their ATA box and/or the entire phone wiring of their home because they were not familiar enough with the electrical load requirements of implementing a system like that. unless you are an electrician or telephone company repair person, this approach is likely to cause more problems than it solves.
Wireless networking is de rigeur these days, but in large buildings or crowded urban environments it can sometimes be difficult to get connections working reliably throughout a facility. Extending your WiFi network allows you to provide strong coverage through a home or workplace while allowing wireless devices to roam about and keep connectivity.
The most reliable way I’ve found to extend WiFi network coverage is to create a single network with multiple Wireless Access Points, connected via a wired backbone to a single internet router. Here’s how this is done.
Create a Single WiFi Network
Many times I’ve arrived at a client’s home or office to find a plethora of WiFi networks in place: Smith Family front and Smith Family Rear, or in a business ABC Corporate WiFi, ABC Sales and Jim’s Network. not only does that mean your computers and smartphones need to join and remember multiple network passwords, but you are probably using multiple routers (and thus multiple DHCP servers and NAT conversions) on the network.
A better alternative is to create a single WiFi Network – Smith Family or ABC Corp WiFi – that is available everywhere via multiple Wireless Access Points (WAPs) thoughout the structure. This provides a single sign-on for convenience and security, and allows you to roam throughout a facility on the same network.
Each WiFi device should be configured to broadcast the same wireless network name (SSID), and use the same password and method of wireless security (WPA2 encryption is best). This image below shows a configuration for an Apple Airport router, other vendor’s equipment will work similarly.
The second important setting is to make sure you have only one router handing out DHCP addresses on your network. for most homes and small businesses this will be the device which connects to your internet provider (Cable, FIOS, DSL, etc.). Your primary router may include WiFi (like an Airport Extreme or Time Capsule) or may be wired only, but either way this should be the only device on the network with a DHCP server enabled.
On all other devices – if they have routing capability – turn off DHCP capability. This prevents potential IP address conflicts and keeps all equipment on the same network subnet. with Apple Airport gear this is via the Internet tab, turn Connection Sharing to Off (Bridge Mode).
Many brands of WiFi routers have a dedicated bridge or wireless access point mode. with others (like the wildly popular Linksys gear) you can disable DHCP services, tape over the WAN port and give the device a fixed IP address on your network to use the router as a WiFi bridge (additional instructions here).
Plan Your Placement and WiFi Channels
WiFi coverage tends to drop off about two rooms or one floor away from the transmitter, varying with the construction of your building. Additional WiFi routers or access points placed throughout your structure about every three rooms or two floors apart will balance out and broaden coverage.
In crowded WiFi environments like an office downtown in a major city, you may need to place WAPs closer and on every floor. Large metal objects, old plaster walls with wire mesh grids inside, or new metal-and-concrete structures can weaken or block signals, so some placement experimentation may be required.
Modern WiFi devices will default to using Automatic channel selection, and in most cases this is fine. if you are in an area with many competing WiFi signals, you may want to use scanning software (like iStumbler on the Mac or a WiFi Finder for the iPhone/iPad) to see what’s around and choose a channel which has relatively little traffic for your setup.
If you set the channel manually, use the same channel on all access points to flood your network with a strong common signal.
Use a Wired Backbone When Possible
Once you’ve configured and placed access points throughout your facility, you need to network them together. a wired backbone is by far the most reliable way to distribute WiFi coverage throughout a structure, and provides a central LAN for fixed computers and devices like printers or non-WiFi equipped gear.
Standard network cabling uses cat5 or cat6 (GigE) ethernet lines, and runs can be up to 500 feet long. if you don’t have enough outputs on your primary router to run a cable to each access point, a switch can be attached to any port to provide additional ethernet jacks for distribution. many newer homes and businesses have ethernet cabling and wall jacks already installed. with older buildings a bit of elbow grease or an electrician’s help may be required to get things setup.
Connect each ethernet cable to your primary router or switch on one end, and to your remote access point on the other. This kind of setup creates a wired-to-wireless bridge in each remote location, nodes that provide WiFi coverage for each area.
If running ethernet cabling isn’t an option, another solution is to use powerline networking. These devices plug into your electrical outlets and bridge your network over in-wall power cabling. This is very convenient, though in practice the brand of equipment used and the condition of your building’s electrical wiring will dictate how speedy and reliable this solution is.
Use WiFi Extenders as a Fallback Choice
Another popular method for extending your WiFi network range is to use a WiFi extender, or a wireless extension feature built into a WiFi router. These devices pick up on existing WiFi signals and rebroadcast them to give a signal boost and extra range. the extender needs to be placed closer to the primary transmitter than a second wired access point would be, in order to stay in range of the original signal for relay.
Configuration should account for the same details as above: use the same network name and password for the extended/repeated signal as the original network, and turn off any DHCP or routing capabilities on the device. You’re just looking to bridge and extend a signal, not create a new network.
In my experience WiFi extenders can be a hit-or-miss proposition. some of my clients have had very good luck with WiFi extenders, others find them unreliable. a wired backbone is preferable when available.

I’ve attended the Black Hat Security conference in Las Vegas for many, many years now. It is by far the best security event each year and this year was no exception. each year seems to go something like this for me:
I attend the conference and get educated on all the new attack vectors, exploits, and general mayhem happening in the digital world. I come home afraid of my digital shadow. throughout the year I pay attention to all the work that is done to close the holes we heard about. I start to feel better about the fate of our digital world; things are looking up! I attend the next years Black Hat Conference. I learn about the new digital Armageddon. I get scared again. Rinse and repeat. I am convinced I’m part of some sick psych experiment. Why do I go you ask? well, I guess it is like going to a NASCAR event. you go for the thrills and the crashes!
Here is a brief glimpse of the messages that were delivered by the various researchers speaking at Black Hat this year. this is my attempt to try and distill a one hour presentation to a one sentence take away. I highly recommend that you don’t take these at face value, they are meant to raise awareness for further study. I recommend you explore the research further so you have all of the facts and the complete picture. (Some of these have already been fixed, Phew):
-The certificate authority system that is so critical to HTTPS/SSL secure website encryption is fatally flawed, has been hacked several times already where certificates were stolen and is generally in need of a major overhaul to fix the lack of true authenticity it is providing today. Authenticity is the thing that keeps us safe from SSL man-in-the-middle attacks. a very cool firefox plug-in that might help this issue was released called convergence by convergence.io. definitely check it out and the paper on this whole issue called perspective.
-MAC OSX 10.7 is a must upgrade for those that take security seriously. Many critical improvements, upgrade now. Lion supports new application sandboxing, XPC for intra-application privilege separation, ASLR improvements and 64bit support, etc.
- great analysis done of how MAC OSX holds up to Advanced Persistent Threats (ATP) attack. In a nutshell, it is way better than XP but in a dead heat with Win7.
-MAC OSX Server has major security issues and is way less secure than Win2008R2. Researcher suggested that OSX Server security is so poor as to not be deployable.
-A researcher showed an exploit against Apple’s new smart batteries used in it MacBook Pro line. the researcher showed how you could hack the battery so it would stop accepting a charge or better yet overheats and catches fire or explodes.
-Do not use Apple’s Bonjour file sharing/network discovery protocol on an untrusted network. It has major security weaknesses such as no authentication, mDNS spoofing, no user interaction required, etc.
-Study was done that shows MAC users aren’t as paranoid as Windows users about security. thus the conclusion was they would be more susceptible to social engineering type attacks like Phishing.
-Researcher found that on several consumer Internet router/firewall products when UPNP was enabled (usually on by default) it worked on both the inside and OUTSIDE interfaces. that would mean that anyone on the Internet would be able to send your router a UPNP message to reconfigure the security settings of your device to let them in. Of course, disabling UPNP has been a best practice for a long time but I know most don’t have any idea.
-Researcher developed a cool tool called nooter and rotonooter that shows if your ISP is bandwidth or rate limiting you, certain websites or certain protocols/services.
-The basic security architecture of iOS is very well done. Lots of complex steps needed to fully compromise a device. Mandatory iOS code signing is enforced at run-time making it very secure. iOS app sandboxing fairly well done but some issues with allowing apps access to over 141 local RPC servers in the OS. iOS 4.3 now includes ASLR for all built-in apps or apps that have been compiled with ASLR PIE. App devs out there please compile your application using PIE; please. unfortunately vast majority don’t. Biggest threat is using browsers embedded in applications. Use the native safari browser instead.
-Apple iOS turns on encryption as soon as you enable a passcode on your device. the complete file system is encrypted. However, as was previously known a simple jailbreak of the phone allows the attacker to decrypt all data. However, in iOS 4.x Apple released data protection. this feature encrypts a subset of the file system using your passcode as the key and not the normal encryption key. this means that even if they jailbreak your iPhone they would still need your passcode to unlock any folders or files protected by data protection. unfortunately, that protection is extremely limited today. Only mail, attachments, profile passwords like active-sync IDs, and apps that ask for data protection through the API have it.
-Clever new spear phishing attack using google alerts was disclosed. this is an APT type attack where you are targeting a person or entity. It works very simply. Many executives, their staff or their marketing department use the Google alerts service to track any and all new web postings that match stuff about them or their company. Basically, it is a tool so folks can be alerted when others are talking about them in articles, blogs, etc. the idea of the spear phish is to setup a drive by download infected website and post an article about the target person or entity on your website. the person will receive a google alert message with your website link in it. the user clicks on the link to see what new press they have received on the web. the malware infected site then compromises their browser and PC. Voila, you now have a foothold into your targets internal network.
You can find the archives of the talks given this year about 6 months from now at https://blackhat.com/html/archives.html
Until then you will have to try and track down the research using google. sorry I can’t provide you more than that. But I can answer any questions you might have if you post them here.
The opinions and information presented here are my PERSONAL views and not those of my employer. I am in no way an official spokesperson for my employer.

A cheap wireless router these days will be one of the older generation 802.11 b or 802.11 g. however, thetraffic on the frequency, 2.4 GHz, used by these cheap wireless routers is heavily congested, especially in cities,so it is better to go for a new 802.11 n series, if you can stretch to it. The 802.11 n is also six times fasterthan a cheap wireless router.
There are hundreds of routers out there and many a cheap wireless router as well. however, bewary of buying a very cheap wireless router, because you may be disappointed with its performance. The differencein price between a cheap wireless router and a good wireless router is not that much, but the difference in qualitycan be huge.
This is especially true if you want to use your cheap wireless router for streaming films, watching TV orplaying games. The old 802.11 b or g technology is usually too slow for modern applications like films andgames.
The latest in the family of 802.11 is the 802.11 n, which can run at 300 MHz instead of the old standard of 54MHz, which means an increase of about 600%. Not only that, but the old 802.11 b/g protocols work on the 2.4 GHzfrequency, which can be a bit crowded these days.
The new standard works on 5 GHz, which is not crowded and is faster, though you will probably not experiencedouble the speed. they also incorporate a QoS technology (Quality of Service) called StreamEngine from Ubicom whichallows packet (data) prioritization. This also has the effect of speeding up the delivery of the data.
You can probably get away with using a cheap wireless router with 802.11 b/g if you are not planning to play thelatest and fastest games. you certainly do not need a fast wireless router just for surfing the Internet.
However, if your laptop has an 802.11 n wireless modem, then you really should keep up with modern technologyand get a wireless router that is capable of taking full advantage of 802.11 n, because they provide much morestable connections over a longer distance and at greater speeds as well.
Should you go for a cheap wireless modem or not? Well, the quick answer is no, but really it depends what youmean. get a good wireless modem for as little as possible by all means, but it really is not worth buying oldtechnology that you know has been superseded just because it is cheap. soon all laptops will be 802.11 n enabledand then you will be losing out with your old router.
A good connection is what makes the Internet fun or a real drag, so if you want more chance of keeping theInternet fun, do not buy a cheap wireless router, it would be better to wait and save up. do not be tempted bymerchants selling off old stocks of cheap wireless router devices and read about what your laptop (or computer) cantake advantage of before you buy anything too advanced.
