Ip.access explained
ip.access Limited is a multinational corporation that designs, manufactures, and markets small cells (picocell and femtocell) technologies and infrastructure equipment for GSM, GPRS, EDGE, 3G, 4G and 5G. The company was acquired by Mavenir in September 2020.
The company’s headquarters is based in Cambourne, England. The company also maintains offices in Gurgaon and Pune, India.
ip.access combines IP and cellular technologies to provide 2G, 3G and LTE coverage and for mobile networks. Using satellite backhaul, its products provide coverage to commercial passenger aircraft,[1] ships,[2] and users in remote rural areas.
The firm is a member of 3GPP,[3] CBRS Alliance, European Telecommunications Standards Institute (ETSI),[4] Having previously been an individual member of the Telecom Infra Project, following its acquisition, ip.access continues to be involved through Mavenir's membership.[5]
History
ip.access was founded in December 1999[6] as a wholly owned subsidiary of TTP Group PLC[7] aimed at developing technologies that would allow multiple radio access technologies to communicate over the Internet. To accommodate its growing staff, in 2006 ip.access relocated to new offices in Cambourne Business Park, Cambridge, where it remains.[8]
In October 2000, TTP Group spun off its communications division (TTP Communications, or TTPCom) in an initial public offering on the London Stock Exchange, and ip.access joined the spin-off as a wholly owned subsidiary of the TTPCom group.
In March 2006, the company secured an £8.5 million round of funding from Intel Capital, Scottish Equity Partners, and Rothschild & Cie Banque.[9] As part of its June 2006 acquisition of TTP Communications, Motorola also gained a stake in ip.access.[10] In 2007, after signing an OEM agreement with ip.access, ADC[11] (now part of Tyco Electronics) made a minority interest investment in the company. Followed by, both Cisco Systems[12] and Qualcomm[13] making strategic financial investments in the company in 2008.
In July 2007, the firm became a founding member of the Femto Forum, renamed Small Cell Forum in February 2012.[14] [15] ip.access was named in The Sunday Times Fast Tech Track 100 in both 2007[16] and 2008.[17] The company was cited as the number one picocell vendor by ABI Research in 2008.[18]
In 2009, ip.access was named in the Deloitte Technology Fast 500 EMEA.[19] In April 2009, the company announced its Oyster 3G product would support femtocell standards published by 3GPP and the Broadband Forum.[20] In March 2010, the company took part in the first Plugfest,[21] organized by ETSI as part of its Plugtests[22] program, held to demonstrate the effectiveness of the 3GPP femtocell standards in supporting interoperability between femtocell access points and network equipment from different vendors.
In June 2011, the market research and analysis firm Infonetics[23] named ip.access along with its partner Cisco Systems, as the leading supplier of 3G femtocells.[24] In August 2011, ip.access[25] announced it had made more than 500,000 installations of its 3G technologies.[26] In February 2013, ip.access announced it had become the first 3G small cell provider to ship one million residential units.[27] In the same month, ip.access and completed successful interoperability testing of 3G small cells over IP Satellite.[28]
In February 2014, ip.access launched a new range of small cells called presenceCell,[29] which unlike traditional small cells, do not rely on providing indoor coverage and capacity to deliver a return on investment. Rather, the ultra-compact base stations are designed to capture anonymous user location and phone identity information from smartphones, which can be analysed and packaged as a service for a variety of businesses.
Private equity fund Zouk Capital invested in ip.access in July 2015[30] alongside Amadeus Capital Partners.
In August 2015, ip.access was named as a partner in the European Commission-funded €8 million Horizon 2020 Project SESAME.[31] Led by Hellenic Telecommunications Organisation (OTE) the project's remit was to develop virtualised cloud-enabled, multi-operator, 5G radio access infrastructure and services. In February, 2016. ip.access launched its Viper platform to provide end-to-end connectivity and management for small cells.[32]
nanoVirt, a virtualised small cell gateway which integrates 2G, 3G and 4G small cell management and access control functions and can run on a carrier-grade Virtual Machine (VM) environment or hosted in a third-party data centre was announced in May 2016.[33] Ip.access has deployed more than 2 million small cells globally which are used by mobile operators to densify their networks to improve network coverage and/or capacity.[34] Small cells are also the foundation for private network use cases based on spectrum sharing such as CBRS in the United States.
AeroMobile and SITAONAIR use ip.access small cells combined with satellite backhaul to provide cellular coverage on commercial and private aircraft.[35] The company also supplies maritime solutions on freight vessels and cruise liners working with partners such as Pentonet, SpeedCast and Telecom26. Ip.access has also provided small cells connected over satellite as rapid deployment disaster response systems. Ip.access small cell solution have also been deployed in Africa, Asia, and Latin America to provide connectivity to rural and remote communities and reduce the digital divide.
Acquisition by Mavenir
On September 27, 2020 ip.access was acquired by Mavenir, the supplier of cloud-native network software to communication service providers. The acquisition allowed the integration of ip.access’ 2G and 3G technologies into Mavenir's existing 4G and 5G OpenRAN portfolio broadband suite and also extend its reach into the enterprise market for private wireless networks based on 3GPP technologies such as 4G/LTE and 5G.
The sale of ip.access Ltd to Mavenir was led by the ip.access management team; Richard Staveley (CEO), Nick Johnson (CTO & Founder), Neil Winrow (COO) and Laura Lawrence (CFO).
The two companies had worked together to deliver Vodafone UK's first Open RAN site at the Royal Welsh Showground in Builth Wells in August 2020.
In November 2020, Mavenir announced the establishment of an OpenRAN Centre of Innovation to be centred at the ip.access headquarters in Cambridge, UK.
Products
The telecommunications firms AT&T[36] uses Oyster 3G as the core femtocell technology for its 3G MicroCell[37] product. Cisco Systems,[38] has jointly developed a femtocell solution with ip.access in compliance with the Broadband Forum's TR-069[20] technical specification.
nanoGSM
In 2002, ip.access introduced the world's first IP basestation controller for indoor GSM networks.[39] nanoGSM uses 2G picocells that leverage the standard GSM air interface, full IP-based BSC, and an OMC-R management system that delivers voice, messaging and data to both 2G and 3G handsets at an indoor range of up to 200m.

In addition to the presenceCell, ip.access also provides the back-end processing and management system that delivers the Presence data anonymously and securely to vertical application providers. The company's Network Orchestration System serves as the infrastructure management solution and also supports the GSMA's OneAPI standard, which allows third parties to provide value-added services through web friendly message interfaces. The presenceCell was commercially deployed by Vodafone Turkey in 2015.[44] In January 2017, ip.access entered into a strategic partnership with wireless network analytics company Inovva to enhance the Presence offering.
Viper
Viper is a virtualised, in-premises enterprise 3G/4G radio access network platform launched in February 2016 that can be deployed by mobile operators or enterprises to offer indoor coverage through a “small cells as a service” (ScaaS) business model.[45] In May 2017, ip.access announced the updating of the Viper2020 Cloud Managed Small Cell platform to support 5G, first responders and neutral host networks with Presence.
