Smarter Homes
The Modern society exhibits increasing demand to utilize new communication services. Today, new services are offered in different packages using standard (copper) networks for cable television and telephony. As both networks have their specific advantages and disadvantages.
Akshita IT Solution is developing an integrated network solution using smart FTTH/Wi-Fi technology in a transparent form, thus enabling all kinds of services through one infra-structure.
Home Surveillance
Video surveillance is an integral part of each and every modern security system for protection of facilities, individuals and assets. In large systems, the video surveillance is integrated with other security systems such as a LPG gas sensor, motion detection, fire detection systems, door sensors.
The greatest trend in video surveillance systems is switch from analog cameras to the IP camera. All recordings of the surveillance cameras are digitalized both for viewing and storing at the computers. Broadband delivery of the so-called four-play services of voice, video, data, and wireless has been offered from traditional telephony service providers. FTTH networks have leveraged cost-effective shared media for the delivery of video content to a large number of subscribers for many years with particular effectiveness in the residential market segment.
Home Automation
Home automation is “The Internet of Things”…The way that all of our devices and appliances will be networked together to provide us with a seamless control over all aspects of our home and more. We offer state-of-the-art home security kits and accessories to protect you and your family from danger, including door and window alarms, garage and driveway alarms, as well as motion detectors.
Features
- Smart IP camera integrates with video surveillance, anti-theft alarm host and smart home control function.
- Through the IP camera, we can communicate through mobile application.
- Alarm signal can be delivered immediately to smart alarm host with RF signal if any illegal invasion (door & window sensor, fire disaster & gas leak) is detected.
- Video record and snapshot will be uploaded to server by host after receiving an alarm signal.
- A push notification is delivered to phone APP by server (due to involving a privacy of family, a privacy mode can be set in APP to prevent a privacy leak) so that a proper measure can be took immediately by checking the scene condition with APP.
Network Layout
The RF spectrum is divided into several ranges, or bands. With the exception of the lowest-frequency segment, each band represents an increase of frequency corresponding to an order of magnitude (power of 10). The following table depicts the eight bands in the RF spectrum, showing frequency and bandwidth ranges. The super high frequency (SHF) and extremely high frequency (EHF) bands are often referred to as the microwave spectrum.
Designation Abbreviation Frequencies Free-space wavelengths
Very Low Frequency VLF 9 kHz to 30 kHz 33 km to 10 km
Low Frequency LF 30 kHz to 300 kHz 10 km to 1 km
Medium Frequency MF 300 kHz to 3 MHz 1 km to 100 m
High Frequency HF 3 MHz to 30 MHz 100 m to 10 m
Very High Frequency VHF 30 MHz to 300 MHz 10 m to 1 m
Ultra High Frequency UHF 300 MHz to 3 GHz 1 m to 100 mm
Super High Frequency SHF 3 GHz to 30 GHz 100 mm to 10 mm
Extremely High Frequency EHF 30 GHz to 300 GHz 10 mm to 1 mm
In the United States, radio frequencies are divided into licensed and unlicensed bands. The Federal Communications Commission issues licenses that permit a commercial entity to have exclusive use of a frequency band in a given location. Unlicensed frequencies are free for public use but remain a shared medium.
Most of the small business organization uses old Electronics Private Branch Exchange (EPBX) System for the telephony communication. This EPBX is now could be replaced by Internet protocol telephony PBX called IP-PBX which uses Intranet as a backbone as each organization has pre installed local area network. The network architecture for the IPPBX system is easy to design & Implement. Keywords — IPPBX, VoIP, SIP. I. INTRODUCTION Small business organizations uses Electronic Private Branch Exchange System for the telephony communication with internal employees and with the outside world, where there is a central Electronics system attached with the user extensions with long copper cables. This system uses a lot of maintenance work as well as requires extra hardware and wiring for the new user extension.
Such organizations which are having the intranet networking facility, as well as WiFi facility for the employees, could change their telephony system to IP-PBX system where there is a central server called IPPBX and the users were get connected through their computer system or laptops via a software called softphone. The softphone are acted as a user extension number which could also run on mobile phones who has wifi facility. II. DESIGNING THE IPPBX SYSTEM The network architecture is shown in figure 1. Fig.1. Network Architecture This network includes an IPPBX server which consists of Intel Atom board with 500GB of the hard disk, 2 GB of RAM, CD-ROM, Super cool cabinet and SMPS of pico PSU 160W which is smallest power supply runs on 12V DC manufactured by “mini-itx”.
Due to this, the PBX server is low power consumption server. This server also consist of dual Ethernet card, one for static IP provided by internet service provider and one for intranet organization communication as shown in the figure. Consider the outside world IP address is 202.XXX.XXX.XXX (IP1) and intranet IP address is 192.168.47.112 (IP2) for the IPPBX server. This IPPBX server could connect on both sides via these two IP address. The IPPBX server consist of Linux based operating system called “trixbox”, developed by “fonality”. The telephony communication is based on Session Initiation Protocol (SIP) which enables the communication between user softphones managed by Asterisk an open source free PBX package. Each user extensions are on desktop PCs or Laptop or SIP-enabled WiFi mobile phones.
Fiber To The Home (FTTH)
As compared to the existing copper wire technology and wireless, which limits the bandwidth capacity, fiber has a very high bandwidth throughout. FTTH technology platform also integrates data, voice & video services that are being rolled out by BSNL with connectivity that has unlimited bandwidth. The state of the art technology provides fix access platform that:
- Delivers the high speed broadband from 256 Kbps to 100 Mbps,
- Enables IPTV with different type of contents like HDTV and future coming 3D TV
- Has a range of voice telephony services
It provides a comprehensive solution for the IP leased line, internet, Closed User Group (CUG), MPLS-VPN, VoIP, video conferencing, video calls etc. Also FTTH enbles to provide bandwidth on demand as per the need of the customer without changing the access fiber and home device.
Basic internet Access Service controlled and uncontrolled from 256Kbps to 1000Mbps.
- TV over IP Service (MPEG2)
- Video on Demand (VoD)(MPEG4) play like VCR
- Audio on Demand Service
- Bandwidth on Demand (User and or service configurable)
- Remote Education
- Point to Point and Point to Multi Point Video Conferencing, virtual classroom.
- Interactive Gaming
- VPN on broadband
- Dial up VPN Service
- Virtual Private LAN Service (VPLS)
- Voice and Video Telephony over IP: Connection under control of centrally located soft switches
