How To Improve Signal Strength to Security System Cellular Backup

If you have an ADT alarm system for your home or business, there is a chance you also have a Safewatch Cellguard cellular backup system in place. This device is a white box with a cellular antenna that acts as a backup connection to your primary internet connection. If your primary internet connection fails, the Cellguard system takes over and runs your alarm over a cellular network.


Everybody understands the importance of having an alarm system, and the benefits of the Safewatch Cellguard are many. The device works in the event of a power outage, lets your alarms function when your ISP is down or experiencing network issues, doesn’t rely on any phone lines, and gives you peace of mind that you’ll be protected 24/7. Something that many people overlook is the cellular signal available where the Cellguard will be installed. A cellular backup is great, but if there isn’t adequate signal available, how can it protect you?

 

Enter the Cel-Fi PRO Signal Booster for AT&T. The Cel-Fi does away with all the complicated setup, issues, and installation costs of typical signal boosters. No mounting antennas to the roof, running cables through walls and ceilings, and no unsightly panel or dome antennas on the walls and ceilings. Instead the Cel-Fi PRO has just two pieces of hardware, a Network Unit (NU) and a Coverage Unit (CU). Installation is as simple as placing the NU in a window where the AT&T signal is the strongest and connecting it to power. The CU is then placed elsewhere in the home or office and connected to power. The NU picks up and amplifies the AT&T signal, wirelessly sends the signal to the CU, and the CU pushes out an amplified cellular signal for any devices in range. It is that simple!


The Cel-Fi PRO will do double duty for you. First it will ensure your Safewatch Cellguard has a strong connection to the cellular network. This means your backup connection for your ADT alarm will be working for you 24/7. Even if it is installed in the center of a brick or metal building, it can be in the reach of the Cel-Fi. Because the Cel-Fi PRO covers up to 13,000 square feet there are very few places it can’t work for you. The second the job the Cel-Fi does of course is to boost the AT&T signal to other devices. AT&T phones, hotspots, and modems, along with the Cellguard, all benefit from an improved cellular signal.

 

The Cel-Fi PRO isn’t limited to working with just ADT systems either. Any alarm system that uses the AT&T 3G, 4G, or 4G LTE network, can take advantage of a simple, zero installation way to boost the signal and provide the peace of mind knowing that your alarm system is working for you all the time.

Read our full review of the Cel-Fi PRO for AT&T!

More Americans Make the Move to Mobile Internet

The US Census Bureau recently announced results from a study they’ve performed the last few years. The study looks at the types of Internet service being used in households across the states and over varying incomes. From what they’re seeing, mobile broadband Internet is growing in terms of usage - whether it be for a household's sole means of getting online OR just a supplement to the traditional services.

In addition to the Census results, the NTIA (National Telecommunications & Information Administration) collected data in July 2015 from close to 53,000 households. It shows that three-quarters of households with internet are using a DSL, cable or fiber connection to get online. With that of course still being the majority, it's actually quite a big drop from 82 percent in 2013.

Households that rely on mobile broadband Internet raised from 10 to 20 percent in the same period. That makes it about one in five US households whose Internet service is now mobile only. The FCC has even expanded its Lifeline program to include mobile connections.

How To Block Shodan.io From Scanning Your network

shodanbanner.jpg
 

Shodan.io is a search engine with the job of crawing the internet for publically acessible servers, software, and equipment. Intended as a site for cyber security experts and researchers, Shodan is a popular destination for those with other intentions as well. While not an inherently bad site, a hacker might want to cause some trouble by remotely accessing a web server with default credentials found on Shodan. News stories over the last few years talk about how Shodan has been used to log into traffic light controls, web cameras, and find databases to exploit.


How do you prevent your network from being scanned and added to Shodan? First you’ll need a router or firewall with more than basic functions. Your device should accept custom firewall rules where you can block by remote IP address. Second you’ll need a list of the servers that Shodan uses to crawl the internet.


Below is a list of known Shodan IP addresses and host names. A firewall rule should be created to block each entry.


93.120.27.62 - m247.ro.shodan.io

85.25.43.94 - rim.census.shodan.io

85.25.103.50 - pacific.census.shodan.io

82.221.105.7 - census11.shodan.io

82.221.105.6 - census10.shodan.io

71.6.167.142 - census9.shodan.io

71.6.165.200 - census12.shodan.io

71.6.135.131 - census7.shodan.io

66.240.236.119 - census6.shodan.io

66.240.192.138 - census8.shodan.io

198.20.99.130 - census4.shodan.io

198.20.70.114 - census3.shodan.io

198.20.69.98 - census2.shodan.io

198.20.69.74 - census1.shodan.io

188.138.9.50 - atlantic.census.shodan.io


If you have a router capable of displaying active sessions or reporting blocked firewall events, you’ll see something like this.

There are of course a number of things you can do to protect yourself from uninvited internet guests. First and foremost, don’t use default credentials for your router, server, database, IP camera, etc. These devices are incredibly easy to find through Shodan and there is never an excuse for defaults! You can also set your router to only allow inbound traffic from known IP addresses. Disabling WAN pings is another way you can try and prevent inbound traffic to your network. The easiest test is to run a Shodan search against yourself. If you know your external IP address, plug it into Shodan and look at the results. Do you see open ports? Do you have devices that are unsecured or running default credentials? The best solution is not to have public facing devices at all and instead to use a VPN to remotely access equipment, but in some situations that just isn't an option and the firewall rules are a fix.


There are a number of routers that can provide the necessary firewall capabilities to block sites like Shodan from scanning your network.

Cradlepoint Announces Cat 6 LTE Advanced Modems and Routers for Multi-Carrier Compatibility

cradlepoint aer2100

Cradlepoint has released a new LTE Advanced (or Cat6-capable modem), as well as updated versions of their embedded routers to utilize the new modem module. The Cat 6 modem supports 4G LTE for all USA, Canada, and Europe carriers, making Cradlepoint's routers more versatile and easier to use than ever before. Unlike their Cat3 multi-band models, which support multiple carriers but must be re-flashed any time a user wants to switch carriers, the Cat 6 devices will automatically detect the carrier when the SIM is installed. Other benefits of the new Cat 6 modem over the older version include:

  • Support for all USA, Canada, and Europe carriers
    • LTE bands: 1-5, 7, 8, 12, 13, 17, 20, 25, 26, 29, 30, 41
    • WCDMA/DC-HSPA+ bands: 1, 2, 3, 4, 5, 8
    • NOTE: the Cat 6 devices do not support Sprint/Verizon 3G
  • New radio band support: Verizon Band 2/5, AT&T Band 12/29/30, Sprint Bands 26/41 (Sprint Spark compatible) and T-Mobile Band 12
  • Carrier aggregation: this allows the equipment to connect to 2x bands at the same time. For example if you've got Band 4 XLTE and Band 13 LTE Verizon coverage at a location the new radios will actually connect to both together instead of only connecting to one or the other. This means higher throughput!
  • Higher throughput: Cat 6 supports up to 300Mbps down and 50Mbps up vs. Cat 3 @ 100/50Mbps 
  • Auto carrier selection

More information about the new Cat 6 modem and routers that utilize it is available at 3Gstore:

How To Get More IP Addresses On Your Network

computerlab.jpg

Just about any home or enterprise grade router out of the box is going to have a default IP address of 192.168.1.1 or similar. What many homeowners or small businesses may never realize is there is a limit to how many devices can be connected to the network. In a typical /24 network, also known as a ‘Class C’ network with a subnet of 255.255.255.0, there are 256 IP addresses. These range from 0 to 255, with 0 and 255 not used in most modern networks. Typically the first usable number is 1, which is reserved for the router, leaving a total of 253 IP addresses for connected devices. 253 IP addresses may seem like a lot, but if you are a business providing WiFi for guests, a school providing connectivity for students, or a large enterprise with 100+ employees with multiple devices, that number can be very limiting.

vlan_example.jpg
 

There are a number of ways that you can increase the address space on your network to accommodate more devices. One way is to configure multiple VLANs. A VLAN is a second network or group of devices that can communicate with each other as if they were all physically connected together. A school may create a new VLAN for each wing of a building, or each computer lab. A VLAN has many benefits including more management and control over devices, and only one router to manage. A VLAN can also be separated from a primary LAN, for example separating a customer network from a sensitive point of sale terminals or other local resources. However a VLAN can be more difficult to configure if your router even supports them to begin with and for some environments, a VLAN may not be necessary at all.

 

classbnetwork.png

This is where you can create a ‘Class B’ network instead. By changing the subnet of your network from 255.255.255.0 or /24 to 255.255.254.0 or /23, you can effectively have 510 IP addresses. If your default LAN IP is 192.168.1.x, with a /23 you would have IP addresses from 192.168.1.1 to 192.168.2.254 available. The great news here is all of your devices will be able to communicate to each other directly. File and printer sharing continue to work, devices can ping each other, and no other complex settings are needed. If you have devices that are assigned a static IP address, just update their subnet mask to the new /23 scheme and they will be ready to go. If you leave them as /24 they can communicate only to their original range of IP addresses. When configured properly, a computer at 192.168.1.10 could ping and print to a device at 192.168.2.254 with no special routing rules or VLAN required.

 

vlanpeplink2.png
 

If you are going to do this on a Peplink or Pepwave router, the steps are extremely simple. First login to your router and visit the Network tab. In the Network Settings pick your router IP address. This is the IP address you’ll use to configure web configure the router. This is also going to be the Gateway address you’ll enter on devices you are assigning static IP addresses. Most important here is to select the proper subnet. The default is /24, but if you switch to /23 you’ll have the additional address space. You then set your DHCP server to the range you want to have handed out automatically. If you want DHCP to hand out all available IP addresses you would set the start address to 192.168.1.2 and the end address to 192.168.2.254.


If you have a high turnover of devices connecting and disconnecting from the network, you can adjust the DHCP lease time. This is how long the router will hold an IP address for a client. The shorter the lease time the quicker addresses return to the DHCP pool. Remember if you are going to be assigning static addresses to devices, ensure they are NOT in the DHCP range or you’ll have IP address conflicts and each device will have limited or no connectivity on your network.

Band Selection on the Pepwave MAX BR1

 

The Pepwave MAX BR1 is a rugged, ready-for-anything M2M connectivity solution that provides unparalleled uptime and dependability in mobile command, first response, surveillance, banking, retail, healthcare, and other deployments. Featuring Automatic Failover between fixed and mobile links, built-in 802.11n Wi-Fi and embedded 4G LTE/3G modem, and SpeedFusion™ persistent session roaming, the MAX BR1 keeps critical voice, data, and video streams flowing fast, without interruption, wherever your work takes you.

br1_top_pic.jpg
 

As a mobile router the Pepwave MAX BR1 has a powerful embedded cellular modem capable of a connection on an North or South American carrier. All you need is an activated SIM card on the network of choice and you’ll be online. Supported networks include Verizon, AT&T, Sprint, and T-Mobile in the US. With cellular carriers introducing more and more cellular technologies, carriers are running data service on multiple different frequencies.


Verizon for example has their 3G, 4G LTE, and 4G XLTE networks which run on different frequencies. Fortunately, the MAX BR1 fully supports all of these technologies and will automatically connect to the cellular network. In some cases, the automatic selection might not be the best choice for your deployment. We’ll take a look at the hidden Advanced Band Selection men on the BR1.


First, you’ll need to ensure your MAX BR1 is running the latest firmware version available here. Once loaded up, head to the Dashboard page of the router, then click the Details tab on the cellular interface. Scroll to the section titled Cellular Settings. On the LTE/3G line, the default setting will be auto. You can also choose to set this to 3G only or LTE only. Next to the LTE/3G heading there is a blue question mark, click this and you’ll see a hidden option to enable Advanced Band Selection. You’ll then see check boxes where you can choose what frequencies you want the router to utilize.

 

br1bandselection.png
 

Why would you want to control the band? With the Verizon example you may be in an LTE area, so you could simply select the LTE only option and be done. However, there is LTE at 700Mhz (Band 13) and XLTE at 1700/2100Mhz (Band 4). The signal strength might be the best at 700Mhz sine that frequency is lower and has better building penetration, but it tends to have slower speeds and more congestion than XLTE does. If your application requires the fastest speeds, you can lock the BR1 to use just Band 4. If you are running a less bandwidth intensive application like uploading ATM transactions you might want to pick Band 13, the standard LTE frequencies. The higher signal strength could result in more reliable connection, although you may have lower overall data speeds. Every situation is different, and all installations have different requirements, and that fine tune control is great for those who need it while staying out of the way for users who do not.

 

br1_back_antennas.jpg

For most users the factory default settings are perfect and there is no reason to make any changes. However you can have much more control over the MAX BR1 with these extra settings. These settings aren’t unique to the MAX BR1 though. Any embedded cellular Peplink router will have this hidden functionality.

Cel-Fi PRO Signal Booster for AT&T - 3G, 4G & 4G LTE Review

If you have a weak cell signal in a home or office, there are a few potential fixes available. One option is to use a microcell from your cellular carrier. These devices use your existing high speed internet connection and tend to have limited coverage, provide slow speeds, and are only as reliable as your ISP. If you don’t have a high speed connection, this isn’t an option at all. The most common way to boost cell signal inside a home or office is with a wireless repeater kit. This consists of an antenna mounted on the roof, cable running inside to an amplifier, and then another cable going to one or more inside antennas at various locations where the signal is needed. Cellular repeater kits have the advantage of working with an existing cellular signal and amplifying it for multiple devices at once, but often times the complexity and cost of installation prevent this from being a viable solution. Repeater kits also suffer from limited range when attempting to boost a weak signal. An amplifier that is capable of covering 5,000 Sq. Ft. under optimal conditions may only improve signal to one or two rooms when the starting signal is less than perfect.

 

(Contents of kit)
 

Enter the Cel-Fi PRO Signal Booster for AT&T. The Cel-Fi does away with all the complicated setup, issues, and installation costs of typical signal boosters. No mounting antennas to the roof, running cables through walls and ceilings, and no unsightly panel or dome antennas on the walls and ceilings. Instead the Cel-Fi PRO has just two pieces of hardware, a Network Unit (NU) and a Coverage Unit (CU). Installation is as simple as placing the NU in a window where the AT&T signal is the strongest and connecting it to power. The CU is then placed elsewhere in the home or office and connected to power. The NU picks up and amplifies the AT&T signal, wirelessly sends the signal to the CU, and the CU pushes out an amplified cellular signal for any devices in range. It is that simple!

(Coverage Unit, CU)
 

The Cel-Fi PRO for AT&T boosts the cellular signal up to 13,000 Sq. Ft on 3G, 4G HSPA+, and 4G LTE with just one NU and one CU. A repeating amplifier capable of that coverage area on the other hand would be significantly more expensive, require multiple rebroadcasting antennas, and in most cases need professional installation. How can the Cel-Fi boost the signal to such a large area with such a small device? The Cel-Fi can operate at up to 100dB of system gain on each band simultaneously. That is 30dB more gain than any other wireless repeater kit available from any other manufacturer. By working with only a single carrier, in this case AT&T, the Cel-Fi doesn’t fall under the FCC Safe Harbor requirements which limits gain to 70dB on other booster products. For every 6dB of power, the coverage distance from the CU doubles making the Cel-Fi solution a significantly more powerful option.

 

(Network Unit, NU)
 

What if you have a larger area to cover? Because the NU and CU communicate wirelessly in the 5Ghz frequency range, multiple Cel-Fi systems can be installed without the concern for interference. Try that with a standard repeater kit and you’ve got a recipe for serious oscillation (feedback between antennas) which will result in a lower output power or cause the amplifier to shut down completely.

 

celfiwave.png
 

With the Nextivity Wave mobile application on iOS and Android devices, registering your device is easy. Before the Cel-Fi pro begins boosting the signal, you’ll connect to the CU with a phone by Bluetooth. When you launch the Wave app you’ll be able to quickly pair to the system and register. Alternatively you can do this from a PC by attaching a USB cable to the CU. Per the FCC, all signal boosters need to be registered with the mobile carrier before use and the Cel-Fi PRO simplifies this with a quick 5 minutes process.


3Gstore has been extensively testing the Cel-Fi PRO in our warehouse over the last 30 days. We already have a standard cellular repeater kit installed in the building with multiple internal antennas to rebroadcast the boosted signal. There is a dome antenna in the hallway to cover the front offices, a dome in the conference room, a dome in our server room to provide coverage for our LTE backup, and a panel antenna to push the signal into our warehouse space. This kit was professionally installed over the course of two days, and provides us coverage for the majority of our location. To test the Cel-Fi, we disconnected our traditional amplifier and ran the NU in the front window of our building. We took the CU and placed it in our warehouse space about 75’ away through 4 walls. After a quick automatic pairing process, the CU indicated it was boosting the AT&T signal. At this point we would usually take a hand held signal meter to various offices to ensure the signal was being boosted where needed, but the effect was immediately obvious just looking at the signal bars on our phones and hotspots. The exact same areas we cover with our roof mounted antenna, amplifier, and 4 internal antennas, were covered in less than 5 minutes by simply plugging the Cel-Fi PRO NU and CU into power.

 

We of course broke out the signal meter to do some real testing as well. The AT&T signal strength at the CU location, with it powered off,  would fluctuate from -100 to -105dBm. On most phones that is the equivalent of a 1 bar signal. With the Cel-Fi powered on we jumped to -60dBm, which is a 5 bar signal! At longer distances within the warehouse, the signal strength slowly decreased just like it does when you move away from a cell tower, but even at the farthest distance from the CU, through multiple office walls, we still had a -90dBm signal. This is a stronger signal at longer distances than our existing amplifier and antennas are capable of, and getting that boost with a simple 5 minute install of a Cel-Fi PRO is like nothing we have ever seen before.

(PRO-X and CU)
 

There are of course locations where wirelessly pairing a NU and CU just isn’t possible. Because the units communicate with each other in the 5Ghz range, major obstacles like concrete walls and ceilings could block communication completely. The Cel-Fi PRO-X is an add on to the Cel-Fi PRO that includes 130’ of ultra low loss cable to connect the two units.

 

 

 (includes NU and CU attachment, 130' cable)
 

You still have all the benefits of the Cel-Fi system including that unheard of 100dB of gain providing that massive coverage area and no requirement to route any external antennas. The cable is especially easy to install in offices or warehouse spaces with drop ceilings or open spaces.

 

 

The minimum requirement for using the Cel-Fi PRO for AT&T is just one bar of signal for the Network Unit to work with (-120dBm RSRP signal minimum). If you are looking for an effective signal booster for your home or office, and would rather not go through the potential headache and hassle of installing a traditional repeater kit, or just want something easy to set up and use, the Cel-Fi PRO is the device for you. The best part? It is just $699. If the goal of the Cel-Fi was to shake up the signal boosting industry, it certainly has done exactly that.


The Cel-Fi PRO for AT&T is available now at 3Gstore!
